    Sjuksköterskestudenters kunskap om oral hälsa: En jämförelse mellan studenter i årskurs 1 och årskurs 32010Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Knowledge of oral health is important so registered nurses, at an early stage, can detect various diseases in the oral cavity. Lack of knowledge in oral health has been reported among registered nurses. The purpose of this study was to compare the knowledge in oral health between nursing students in grade 1 and grade 3. The study was based on a questionnaire with fixed response alternatives that were distributed by the author to nursing students in grade 1 and grade 3 at Kristianstad University. The students claimed to have good theoretical and practical knowledge while the survey revealed that there were gaps in knowledge. The results showed also that there was a statistically significant difference in knowledge between students in grade 1 and grade 3 concerning candidiasis, xerostomia, prosthesis and oral health assessments. In this study the knowledge is low in several areas within oral health among the nursing students. Increased education is desirable to ensure adequate oral health procedures among patients in hospital or nursing homes.

    Development of an instrument to assess oral hygiene ability in older adults: the oral hygiene ability instrument2019In: Gerodontology, ISSN 0734-0664, E-ISSN 1741-2358Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: To describe the development process of an instrument to assess the ability to manage daily oral hygiene and the cause of impaired oral hygiene. The instrument is initially aimed for use by the dental team in the ageing population.

    BACKGROUND: Oral hygiene is an important component of oral health. Inability to manage oral hygiene combined with other risk factors often results in poor oral health and impaired quality of life.

    METHODS: A guideline for instrument development was used during the construction of the instrument. The method included three phases: I. planning: the purpose and target group of the instrument were determined, and a literature review and qualitative focus-group study were conducted; II. construction: objectives were formulated, and a pool of items was built; and III. evaluation and validation, which included two pilot studies, interviews, item analyses and revision of the instrument.

    RESULTS: The planning and construction phases resulted in an instrument with 47 items comprising three parts: (a) interview, (b) clinical examination and (c) observation of activities of daily living (oral hygiene). After two pilot studies, the instrument was found to have good content validity. Analyses of qualitative and quantitative data resulted in a reduction in the number of items to 33.

    CONCLUSION: OHAI can be a valuable tool as a preventive method to identify older adults at risk of impaired oral health. However, the instrument needs further evaluation before wider use.

    Abstract [en]

    General health is crucial in upbringing a child. Good oral health is an essential part of good general health. The aim of this study was to evaluate pregnant women's knowledge about nutrition, oral hygiene and caries in children under three years. A quantitative method was used with questionnaire. The study was carried on pregnant women and the questionnaires were distributed by midwives. Descriptive statistical analysis was performed based on 243 responses. The result indicates that 10 % of the pregnant women replied that freshly squeezed juice should preferably be given between meals. Of the respondents, 93 % responded that the teeth should be brushed twice a day. When asked if a baby tooth is more susceptible to caries than an adult tooth for caries 60% responded incorrectly no, or do not know. The conclusion suggests that pregnant women’s knowledge of oral care in children under three years is good, but knowledge with regard to diet and caries is lower.

    Comparison between the Klemetti index and heel DXA BMD measurements in the diagnosis of reduced skeletal bone mineral density in the elderly.2005In: Osteoporosis International, ISSN 0937-941X, E-ISSN 1433-2965, Vol. 16, no 8, p. 999-1003Article in journal (Refereed)
    Abstract [en]

    Osteopenia/osteoporosis affect many elderly people and might not be detected until symptoms of fractures occur. Early detection of osteopenia/osteoporosis is important and would allow preventive measures and treatment. Access to screening for osteopenia/osteoporosis is often limited, whereas panoramic radiography is commonly used in dentistry. The aim of this study was to determine the validity of the Klemetti index (KI), measured on panoramic radiographs, in the diagnosis of osteopenia/osteoporosis as defined by a bone mineral density (BMD) measurement below -1.5 standard deviations (SDs) of a community based sample. In total, 211 consecutive participants (102 men and 109 women) 60-96 years in the SNAC-Blekinge study (Swedish National Study on Ageing and Care) underwent bone densitometry [by dual-energy X-ray absorptiometry (DXA)] of both heels. A panoramic radiograph was taken of each participant, and mandibular cortex on a panoramic radiograph was classified as '0' or normal (even and sharp endosteal margin), '1', moderately eroded (evidence of lacunar resorption or endosteal cortical residues), or '2', severely eroded (unequivocal porosity). From logistic regression, the odds ratio of having a BMD measurement below -1.5 SD was 8.04 (95% CI 2.39 to 27.12, P<0.001) in the 'osteopenic' (KI category 2), compared with the 'normal' group (KI categories 0 and 1). Receiver operating characteristic (ROC) curve analysis was used to measure the validity of the KI indicating osteopenia (KI category 2) in predicting reduced BMD. This point provided a sensitivity of 50% and a specificity of 89%. Positive and negative predictive values were 21% and 97%, respectively. There were 87% correctly classified subjects. The area under the ROC curve was 0.64. The present study demonstrated that a negative finding (KI category <2) is highly predictive of the absence of osteopenia/osteoporosis as defined by the DXA measurements.

    Probiotic supplements and debridement of peri-implant mucositis: a randomized controlled trial2015In: Acta Odontologica Scandinavica, ISSN 0001-6357, E-ISSN 1502-3850, Vol. 74, no 1, p. 60-66Article in journal (Refereed)
    Abstract [en]

    Objective.

    The aim of this double-blind randomized placebo-controlled trial was to evaluate the effects of probiotic supplements in adjunct to conventional management of peri-implant mucositis.

    Materials and methods.

    Forty-nine adult patients with peri-implant mucositis were consecutively recruited after informed consent. After initial mechanical debridement and oral hygiene instructions, the patients received a topical oil application (active or placebo) followed by twice-daily intake of lozenges (active or placebo) for 3 months. The active products contained a mix of two strains of Lactobacillus reuteri. Patients were clinically monitored and sampled at baseline and after 1, 2, 4, 12 and 26 weeks. The clinical end-points were pocket-probing depth (PPD), plaque index (PI) and bleeding on probing (BOP). In addition, the subgingival microbiota was processed with checkerboard DNA-DNA hybridization and samples of gingival crevicular fluid (GCF) were analyzed for selected cytokines with the aid of multiplex immunoassays.

    Results.

    After 4 and 12 weeks, all clinical parameters were improved in both the test and the placebo group. PPD and BOP were significantly reduced compared with baseline (p < 0.05), but no significant differences were displayed between the groups. The clinical improvements persisted 3 months after the intervention. No major alterations of the subgingival microflora were disclosed and the levels of inflammatory mediators in GCF did not differ between the groups.

    Conclusions.

    Mechanical debridement and oral hygiene reinforcement resulted in clinical improvement of peri-implant mucositis and a reduction in cytokine levels. Probiotic supplements did not provide added benefit to placebo.

    Effect of probiotic lozenges on inflammatory reactions and oral biofilm during experimental gingivitis2013In: Acta Odontologica Scandinavica, ISSN 0001-6357, E-ISSN 1502-3850, Vol. 71, no 3-4, p. 828-833Article in journal (Refereed)
    Abstract [en]

    Aim. Probiotic bacteria have been introduced for prevention and treatment of periodontal diseases. The aim was to assess if daily oral administration of probiotic bacteria could influence the inflammatory response and the composition of supragingival plaque in an experimental gingivitis model. Materials and methods. Eighteen healthy female adults volunteered after informed consent. A double-blind randomized placebo-controlled cross-over design was used. The buccal surface of first molars was used as experimental sites. A mouth-guard covering the first premolar to second molar was used when brushing, preventing accidental cleaning during 3 weeks of plaque accumulation. Lozenges containing L. reuteri (ATCC55730 and ATCC PTA5289) or placebo were taken twice a day. During the run-in and washout periods, professional tooth cleaning was performed 5 days/week. At baseline and follow-up, plaque index, gingival index and bleeding on probing were recorded. Samples of gingival crevicular fluid (GCF) were analysed for concentration of seven inflammatory mediators. Bacterial samples were processed with checkerboard DNA/DNA-hybridization. Results. All subjects presented a local plaque accumulation and developed manifest gingivitis at the test sites during the intervention periods. The volume of GCF increased in both groups but was statistically significant only in the placebo group (p < 0.05). The concentrations of IL1-β and IL-18 increased significantly (p < 0.05), while IL-8 and MIP1-β decreased (p < 0.05). No differences were displayed between test and placebo. Likewise, the microbial composition did not differ between the groups. Conclusion. Daily intake of probiotic lozenges did not seem to significantly affect the plaque accumulation, inflammatory reaction or the composition of the biofilm during experimental gingivitis.

    Systemic antibiotics and debridement of peri-implant mucositis: a randomized clinical trial2012In: Journal of Clinical Periodontology, ISSN 0303-6979, E-ISSN 1600-051X, Vol. 39, no 6, p. 574-581Article in journal (Refereed)
    Abstract [en]

    Background This RCT compared non-surgical treatment of peri-implant mucositis with or without systemic antibiotics. Materials and Methods Forty-eight subjects received non-surgical debridement with or without systemic Azithromax ® (4 days), and were followed during 6 months. The checkerboard DNA-DNA hybridization method was used to analyse the microbiological material. Results Five subjects were excluded due to antibiotic medication during follow-up. At baseline,1 and 3 months no group differences were found. Statistical analysis failed to demonstrate differences in probing pocket depths (PPD) values at 6 months (Mean diff PPD: 0.5 mm, SE: ±0.4 mm, 95% CI: −0.2, 1.3, p = 0.16). Mean% implant bleeding decreased between baseline and month 6 from 82.6% to 27.3% in the test, and from 80.0% to 47.5% in the control group (p < 0.02). Throughout the study, no study group differences in bacterial counts were found. Conclusion No short-term differences were found between study groups. The clinical improvements observed at 6 months may be attributed to improvements in oral hygiene. The present study does not provide evidence for the use of systemic antibiotics in treatment of peri-implant mucositis.

    Reproducibility of subgingival bacterial samples from patients with peri-implant mucositis2015In: Clinical Oral Investigations, ISSN 1432-6981, E-ISSN 1436-3771, Vol. 19, no 5, p. 1063-1068Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: The aim of the present study was to investigate the reproducibility of bacterial enumeration from subsequent subgingival samples collected from patients with peri-implant mucositis.

    MATERIAL AND METHODS: Duplicate microbial samples from 222 unique implant sites in 45 adult subjects were collected with paper points and analyzed using the checkerboard DNA-DNA hybridization technique. Whole genomic probes of 74 preselected bacterial species were used. Based on the bacterial scores, Cohen's kappa coefficient was used to calculate the inter-annotator agreement for categorical data. The percentage agreement was considered as "good" when the two samples showed the same score or differed by 1 to the power of 10.

    RESULTS: Moderate to fair kappa values were displayed for all bacterial species in the test panel (range 0.21-0.58). There were no significant differences between Gram-positive and Gram-negative species. The percentage of good agreement between the first and second samples averaged 74.7 % (n = 74; range 56-83 %), while the proportion of poor agreement ranged from 1 to 19 % for the various strains.

    CONCLUSION: While an acceptable clinical agreement was obtained in most cases, diverging bacterial scores may appear in subgingival samples collected at the same time point from patients with peri-implant mucositis.

    CLINICAL RELEVANCE: The broad bulky base of implant crowns may present an obstacle for the collection of reproducible subgingival samples with paper points.

    Open flap debridement of peri-implantitis with or without adjunctive systemic antibiotics: a randomized clinical trial.2017In: Journal of Clinical Periodontology, ISSN 0303-6979, E-ISSN 1600-051X, Vol. 44, no 12, p. 1285-1293Article in journal (Refereed)
    Abstract [en]

    AIMS: To investigate clinical, radiographic and microbiological outcome over 12 months following open flap debridement of peri-implantitis with or without antibiotics.

    MATERIALS AND METHODS: Peri-implantitis was surgically treated with or without Zithromax(®) in 19 control and 20 test individuals. Probing pocket depth (PPD), gingival inflammation (BOP), intra-oral radiographs and microbial samples were studied. Per protocol, and intent to treat analyzes were performed.

    RESULTS: The mean difference (reduction) in PPD values between baseline and month 12 in the test and control groups were: 1.7 mm (SD ± 1.1, 95% CI: 1.1, 2.3, p < 0.001), and 1.6 mm (SD ± 1.5, 95% CI: 0.8, 2,4, p < 0.001), respectively. Data analysis failed to show study group differences for BOP, PPD, radiographic bone level, and microbial load. Succesful treatment (per protocol: PPD≤ 5 mm, no BOP, no suppuration and no bone loss ≥ 0.5 mm) at 12 months in test and control groups were 7/15 (46.7%), and 4/16 (25.0%). Bacterial load reduction was similar in study groups with a temporary reduction following treatment.

    CONCLUSIONS: Surgical treatment of peri-implantitis with adjunctive systemic azithromycin did not provide one-year clinical benefits in comparison to those only receiving open flap debridement. This article is protected by copyright. All rights reserved.

    Virus vid lokal aggresiv parodontit studeras2009In: Tandläkartidningen, ISSN 0039-6982, Vol. 101, no 3, p. 58-Article in journal (Other academic)
    Abstract [sv]

    Under det senaste decenniet har virus roll i parodontitsjukdomens uppkomst och progression studerats. Data har publicerats som visar att virus förekommer och eventuellt har betydelse för sjukdomsutvecklingen vid vissa typer av parodontit. Vi har därför undersökt förekomsten av bakterier och virus hos ett antal unga patienter med lokal aggressiv parodontit. Vår studie kan dock varken belägga eller avvisa hypotesen om virusförekomstens betydelse.

    Abstract [en]

    The purpose of this study was to investigate parents' knowledge about diet and dental caries. The survey was conducted using a structured questionnaire consisting of 19 questions regarding knowledge of diet and caries, and preventive measures. The questionnaires were distributed to parents who were visiting a dental hygienist or prophylaxis nurse with their children aged 0-3 years. A total of 88 completed surveys were collected. The study showed that the majority of the parents had knowledge about diet and dental caries. They had good knowledge about snacking, poor oral hygiene and that diet and feeding contents of the bottle can cause tooth decay. Parents have an important responsibility to guide the child to achieve a good general oral health. Thus, dental professionals, especially dental hygienists, have an important role in preventing tooth decay.

    Kariesförekomst hos invandrarbarn i Sverige, Norge, Finland och Danmark2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Of all the children in the world 90% have had tooth decay. World Health Organisation has established goals to reduce the caries prevalence. In the year of 2000, the goal was that 12 - year-olds should not exceed DMFT 3 and 2020, 80% of all the world's children at aged 6 should be caries-free. The aim of this study was to describe the prevalence in children aged 3-19 years, with an immigrant background in Sweden, Norway, Finland and Denmark. The method that was used was a literature review. Data were searched in PubMed using the keywords "children", "immigrant", "immigrants", "caries". Papers before the year 2000 were excluded. Nine scientific papers were found. Non of these were found from Finland. The caries prevalence was presented in dmfs/DMFS, dmft/DMFT, dfs/DFS and in percentage. The result showed a high caries index in Sweden, Norway and Denmark. The conclusion suggests that children and adolescents with immigrant backgrounds have a high caries prevalence in these countries.

    Diagnosis of periimplant disease2019In: Implant Dentistry, ISSN 1056-6163, E-ISSN 1538-2982, Vol. 28, no 2, p. 144-149Article in journal (Refereed)
    Abstract [en]

    PURPOSE: The aim of this review is to describe the current guidelines for the differential diagnosis of periimplant diseases.

    MATERIALS AND METHODS: Synopsis reviews were conducted to define the differential diagnosis of periimplant disease through an electronic literature search in MEDLINE up to February 2018.

    DISCUSSION: Periimplant mucositis is defined by the presence of bleeding and/or suppuration on gentle probing with or without an increased probing depth compared with previous examinations and by the absence of bone loss beyond crestal bone-level changes resulting from initial bone remodeling. Periimplantitis is defined by the presence of bleeding and/or suppuration on gentle probing with an increased probing depth compared with previous examinations and by the presence of bone loss beyond crestal bone-level changes resulting from initial bone remodeling. Thus, a combination of clinical registrations (probing pocket depth, bleeding on probing, and presence of pus) combined with radiographic signs of possible bone loss is needed for differential diagnosis.

    CONCLUSIONS: An accurate baseline registration at the time of placement of the prosthesis (probing pocket depth and bone level) with ongoing yearly monitoring is essential for diagnosis and appropriate disease management.

    Abstract [en]

    The aim of the study was to describe how patients experienced communication, treatment and costs at the dental hygienist program at Högskolan Kristianstad. The study was based on a questionnaire that was made at the patient clinic. The questionnaire was conducted by the treating dental hygienist student after the treatment. The questionnaire was answered in the waiting room. Collection of the material occurred during the month of March in 2009. There were totally 111 patients that participated in this study. The results of the study showed that 92.8% of patients thought that the atmosphere at the reception was calm and efficient. More than two thirds of the participating patients (63.1%) felt very safe in the treatment chair. 81.1% of the patients that participated in this study thought that they got very good treatment by the dental hygienist student. The majority of the participated patients (59.5%) also considered the price for the treatment as reasonable. The conclusion of this study is that the majority of the patients have a positive attitude in terms of communication, treatment and price towards the patient clinic at Högskolan Kristianstad.

    Improved general and oral health in diabetic patients by an Okinawan-based Nordic diet: a pilot study2018In: International Journal of Molecular Sciences, ISSN 1422-0067, E-ISSN 1422-0067, Vol. 19, no 7, article id E1949Article in journal (Refereed)
    Abstract [en]

    Periodontal disease, periodontitis as well as the preceding gingivitis, has been associated with both obesity and diabetes. Studies have shown that diet changes can lead to a lower incidence of such inflammation. The aim of the present case series over four weeks was to study the effects on medical and dental conditions in patients with type 2 diabetes of the consumption of the Okinawan-based Nordic Diet (OBND&reg;). Medical and dental examinations were performed to estimate the general health and gingivitis/periodontitis. Serum cytokine levels were assessed using Luminex technology. Eight of ten study participants completed the study. All participants lost weight (p = 0.012). Six out of seven that were treated with insulin could reduce their insulin intake after two weeks with OBND&reg;. The reduction was about 16 units which corresponds to a 34% relative reduction compared to the starting point (range 15⁻63%). Fasting blood glucose values fell (p = 0.035). Hemoglobin A1c (HbA1c) (p = 0.01), triglycerides (p = 0.05), and low-density lipoprotein (LDL) (p = 0.05) were also reduced. Bleeding on probing changed from ~28% before any dietary changes to ~13% after two weeks with OBND&reg; (p = 0.01). The reduction in gingival bleeding was as substantial as might be expected from one session of professional tooth cleaning. Markers of inflammation were also reduced. The OBND&reg; thus showed significant promise in alleviating the impact of diabetes on dental as well as general health.

    Tandhygienisters upplevelse av hälsofrämjande arbete2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien var att undersöka hur oralt hälsofrämjande arbete upplevdes av legitimerade tandhygienister. En kvalitativ studie har genomförts och datainsamlingen gjordes genom intervjuer med en intervjuguide som underlag. Åtta deltagare från två folktandvårdskliniker i Skåne intervjuades och intervjuerna varade i 11-20 minuter. Materialet analyserades utifrån en kvalitativ innehållanalys. Resultatet redovisas utifrån temat ”Tandhygienister har ett stort ansvar i sitt hälsofrämjande arbete”. Deltagarna upplevde att hälsofrämjande arbete är betydelsefullt, att de har goda förutsättningar och möjligheter att påverka patienterna att uppnå en god oral hälsa. Patienternas motivation och tandhygienistens engagemang är av stor vikt för att uppnå förståelse hos patienter om egenvård och vad god oral hälsa innebär. Deltagarna anser att de har ett ansvar som legitimerade tandhygienister att hjälpa patienterna att uppnå och bibehålla en god oral hälsa. Majoriteten av deltagarna upplevde att en god oral hälsa inte bara är viktig för tändernas hälsa utan även för hälsan i övrigt. Slutsatsen av studien är att är att tandhygienister upplever att de har ett stort ansvar när det gäller hälsofrämjande arbete samt att det finns goda möjligheter att påverka patienter att uppnå en god oral hälsa genom hälsofrämjande arbete. Patienter som inte är intresserade och inte tar ansvar för sin egen munhälsa är en utmaning för deltagarna vid oralt hälsofrämjande arbete.

    Socioekonomiska faktorers påverkan på kariesrisk hos barn 0-12 år i Sverige2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med litteraturstudien var att undersöka socioekonomiska faktorers påverkan på kariesrisken hos barn 0-12 år i Sverige. Metod: Studien genomfördes som en systematisk kvantitativ litteraturstudie, sökningen av vetenskapliga artiklar gjordes i PubMed. Resultat: Låg socioekonomisk status gav högre kariesrisk än hög socioekonomisk status. Barn till mödrar med låg utbildningsnivå hade 3.02 gånger ökad kariesrisk än barn till mödrar med hög utbildningsnivå. Barn med två utlandsfödda föräldrar hade 6.37 gånger ökad kariesrisk i förhållande till barn med föräldrar födda i Sverige. Slutsats: Barn till föräldrar med låg socioekonomisk status hade högre kariesrisk än barn till föräldrar med hög socioekonomisk status oberoende av föräldrarnas/familjens inkomst, föräldrarnas utbildning, föräldrarnas bakgrund, föräldrarnas/familjens hälsa/vanor/attityder eller geografiskt område.

    Uppfattningar och upplevelser av hypnoterapi mot tandvårdsrädsla2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Aim: The aim of this study was to investigate the perceptions of hypnotherapy’s effects and experiences of hypnotherapy as a treatment of dental fear in dental clinics.

    Material and Methods: The material was obtained through interviews with six informants working with hypnotherapy as a treatment for dental fear in dental clinics in Sweden. The interviews were conducted using an interview guide and lasted 20 - 35 minutes. The method was qualitative and the interviews were analyzed through a qualitative content analysis.

    Results: In the results a main theme appeared: Preventive treatment. The results showed that the informants perceived hypnotherapy’s effects as good and they experienced hypnotherapy as effective in the treatment of dental fear. The informants agreed that hypnotherapy should be used in dental clinics and performed by a dentist or dental hygienist. Many of the informants felt that their colleagues had difficulties accepting hypnotherapy as a method.

    Conclusion: Perceptions and experiences of hypnotherapy as a treatment and its effect are generally positive with some exceptions regarding their colleagues attitudes towards the method. More research is needed to bring a wider acceptance and understanding of hypnotherapy as a treatment method.

    Effectiveness of enamel matrix derivative on the clinical and microbiological outcomes following surgical regenerative treatment of peri-implantitis: a randomized controlled trial2016In: Journal of Clinical Periodontology, ISSN 0303-6979, E-ISSN 1600-051X, Vol. 43, no 10, p. 863-873Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: This randomized clinical trial aimed at comparing radiological, clinical and microbial effects of surgical treatment of peri-implantitis alone or in combination with enamel matrix derivative (EMD).

    METHODS: Twenty-six subjects were treated with open flap debridement and decontamination of the implant surfaces with gauze and saline preceding adjunctive EMD or no EMD. Bone level (BL) change was primary outcome and secondary outcomes were changes in pocket depth (PD), plaque, pus, bleeding and the microbiota of the peri-implant biofilm analyzed by the Human Oral Microbe Identification Microarray over a time period of 12 months.

    RESULTS: In multivariate modelling, increased marginal BL at implant site was significantly associated with EMD, the number of osseous walls in the peri-implant bone defect and a Gram+/aerobic microbial flora, whereas reduced BL was associated with a Gram-/anaerobic microbial flora and presence of bleeding and pus, with a cross-validated predictive capacity (Q(2) ) of 36.4%. Similar, but statistically non-significant, trends were seen for BL, PD, plaque, pus and bleeding in univariate analysis.

    CONCLUSION: Adjunctive EMD to surgical treatment of peri-implantitis was associated with prevalence of Gram+/aerobic bacteria during the follow-up period and increased marginal BL 12 months after treatment.

    ”Early childhood caries” och associerade riskfaktorer bland barn i Europa2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Early childhood caries (ECC) is a form of dental caries that affects children at an early age. The disease is characterized by a rapid progression and it usually affects smooth surfaces of the primary teeth.

    Aim: The aim of this study was to describe the prevalence and identify risk factors for early childhood caries (ECC) among children between 0-6 years in Europe.

    Method: The material used in this review is scientific publications mainly collected from the medical database PubMed. The results are based on a compilation of 15 scientific articles published between 2000-2014.

    Results: The prevalence of ECC ranged from 13.0-85.0 % in different countries and populations in Europe. The lowest and highest occurrence of ECC was observed among children in Sweden. ECC was associated with dietary and oral hygiene habits, along with several socioeconomic factors, where the parent’s educational level, employment status and ethnicity were the most significant factors. Breastfeeding and the use of baby bottle were behavioral factors that showed an association with increased prevalence of ECC.

    Conclusion: ECC exists in both Western and Eastern European countries. Dietary and oral hygiene habits are very important for the development of ECC, but the disease has also a relation with several behavioral and socioeconomic factors.

    Effect of oxybenzone on PGE2-production in vitro and on plaque and gingivitis in vivo2004In: Journal of Clinical Periodontology, ISSN 0303-6979, E-ISSN 1600-051X, Vol. 31, no 2, p. 91-94Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: To study the effect of oxybenzone on prostaglandin E2 (PGE2) production in cell culture and to evaluate the effect of an oxybenzone-containing dentifrice on plaque and gingivitis in a 6-week clinical trial.

    MATERIAL AND METHODS: Human embryo palatal mesenchyme (HEPM) cells were used for testing the inhibition of IL-1beta-stimulated PGE2-production in vitro by different concentrations of oxybenzone. For the in vivo study, a total of 66 individuals with a Quigley & Hein plaque index of at least 1.5 and an Ainamo & Bay gingival index of at least 0.2 were included in a double-blind clinical trial with two cells and a parallel design. Two compositions of fluoride dentifrice were used, one with the addition of 0.5% oxybenzone, and one without. Plaque and gingival index were obtained at three time points: (1) at baseline, (2) after 3 weeks, and (3) after 6 weeks.

    RESULTS: A dose-dependent inhibition of PGE2-production was found in the HEPM cell culture following oxybenzone exposure. In the clinical trial, a 25% reduction of gingival index was observed in the oxybenzone group (p<0.001) after 6 weeks as compared with 2% for the placebo group.

    CONCLUSIONS: These findings indicate that PGE2-production is reduced by oxybenzone in vitro and that the use of oxybenzone in a dentifrice reduces gingivitis in vivo.

    Regenration of alveolar ridge defects: Consensus report of group 4 of the 15th European Workshop on Periodontology on Bone Regeneration2019In: Journal of Clinical Periodontology, ISSN 0303-6979, E-ISSN 1600-051X, Vol. 46, p. 277-286Article in journal (Refereed)
    Abstract [en]

    BACKGROUND AND AIMS: Bone augmentation procedures to enable dental implant placement are frequently performed. The remit of this working group was to evaluate the current evidence on the efficacy of regenerative measures for the reconstruction of alveolar ridge defects.

    MATERIAL AND METHODS: The discussions were based on four systematic reviews focusing on lateral bone augmentation with implant placement at a later stage, vertical bone augmentation, reconstructive treatment of peri-implantitis associated defects, and long-term results of lateral window sinus augmentation procedures.

    RESULTS: A substantial body of evidence supports lateral bone augmentation prior to implant placement as a predictable procedure in order to gain sufficient ridge width for implant placement. Also, vertical ridge augmentation procedures were in many studies shown to be effective in treating deficient alveolar ridges to allow for dental implant placement. However, for both procedures the rate of associated complications was high. The adjunctive benefit of reconstructive measures for the treatment of peri-implantitis-related bone defects has only been assessed in a few RCTs. Meta-analyses demonstrated a benefit with regard to radiographic bone gain but not for clinical outcomes. Lateral window sinus floor augmentation was shown to be a reliable procedure in the long-term for the partially and fully edentulous maxilla.

    CONCLUSIONS: The evaluated bone augmentation procedures were proven to be effective for the reconstruction of alveolar ridge defects. However, some procedures are demanding and bear a higher risk for postoperative complications. This article is protected by copyright. All rights reserved.

    Dental implants from the patients perspective: transition from tooth loss, through amputation to implants – negative and positive trajectories2012In: Journal of Clinical Periodontology, ISSN 0303-6979, E-ISSN 1600-051X, Vol. 39, no 7, p. 681-687Article in journal (Refereed)
    Abstract [en]

    Aim The aim of this study was to explore patients' expectations on and experiences from dental implant treatment through deep-interview technique. Material & Methods A qualitative study design was chosen and 17 patients were interviewed by open-ended questions. All patients in the study had a previous history of periodontal disease with, in most cases, many years of treatment. The interviews were transcribed; a coding process was used according to qualitative conventional content analysis. Results In the analysis, a core category was identified as “Transition from tooth loss, to ‘Amputation’, and to implants – negative and positive trajectories”. When the patients faced the fact that it was not possible to keep the teeth any longer, a period of fear, shame and denial, which also affected their social life negatively followed. After they received their implants and the chewing ability and appearance became better, it also improved their quality of life. Conclusion Treatment with dental implants improved function, enhanced self-esteem, social life and, thus quality of life. In clinical practice, information about dental implants and motivational strategies are needed during the period before getting dental implants. Follow-up is important thereafter, capturing both the pros and cons with implants.

    Differences in four reported symptoms related to temporomandibular disorders in a cohort of 50-year-old subjects followed up after 10 years2008In: Acta Odontologica Scandinavica, ISSN 0001-6357, E-ISSN 1502-3850, Vol. 66, no 1, p. 50-7Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To assess possible changes in the prevalence of four temporomandibular disorder (TMD) symptoms reported by subjects at age 50 and again 10 years later. MATERIAL AND METHODS: Identical questionnaires were sent out in 1992 and in 2002 to all subjects born in 1942 and living in two Swedish counties. Of those who answered the four questions on TMD symptoms in 1992, 74% responded in 2002 (n=4639). The response alternatives were dichotomized into two groups: 1) No problems and 2) some, rather severe and severe problems. RESULTS: The mean prevalence of TMD-related symptoms reflected small and mainly non-significant changes, whereas the prevalence of reported bruxism was significantly greater at age 60 than at age 50. Among those with no TMD symptoms at age 50, 5-7% of the men and 8-9% of the women reported symptoms at age 60. Of those reporting one or more TMD symptoms at age 50, 47-65% of the men and 40-48% of the women had no symptoms 10 years later. There was a significant and markedly increased risk of reporting TMD symptoms and bruxism (OR>10) at age 60 among those who had symptoms at age 50. CONCLUSIONS: The mean prevalence of reported TMD symptoms was relatively consistent from age 50 to age 60. The group reporting symptoms at the first examination were highly likely still to have the symptoms 10 years later. However, approximately half of the subjects with TMD symptoms at age 50 reported no symptoms at age 60.

    Effect of soft drinks on proximal plaque pH at normal and low salivary secretion rates2007In: Acta Odontologica Scandinavica, ISSN 0001-6357, E-ISSN 1502-3850, Vol. 65, no 6, p. 352-356Article in journal (Refereed)
    Abstract [en]

    Objective. The aim of this study was to investigate the effect of different types of drinks on plaque pH during normal and drug-induced low salivary secretion rates.

    Material and methods. Three drinks were tested in 10 healthy adult subjects: 1) Coca-Cola regular, 2) Coca-Cola light, and 3) fresh orange juice. pH was measured in the maxillary incisor and premolar region with the microtouch method. The area under the pH curve (AUC) was calculated.

    Results . During normal salivary condition, mouth-rinsing with Coca-Cola regular resulted in a slightly more pronounced drop in pH during the first few minutes than it did with orange juice. After this initial phase, both products showed similar and relatively slow pH recovery. Coca-Cola light also resulted in low pH values during the very first minutes, but thereafter in a rapid recovery back to baseline. During dry mouth conditions, the regular Cola drink showed a large initial drop in pH, and slightly more pronounced than for orange juice. After the initial phase, both products had a similar and slow recovery back to baseline. At most time-points, AUC was significantly greater in dry conditions compared to normal conditions for Coca-Cola regular and orange juice, but not for Coca-Cola light. Coca-Cola light generally showed a significantly smaller AUC than Coca-Cola regular and orange juice.

    Conclusions. The main conclusion from this study is that a low salivary secretion rate may accentuate the fall in pH in dental plaque after gentle mouth-rinsing with soft drinks.

    Ungdomars syn på den egna orala hälsan och påverkan på livskvalitén2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien var att belysa ungdomars upplevda orala hälsa och dess påverkan på livskvalitén. Studien genomfördes som en kvalitativ intervjustudie med nio informanter i åldern 18-19 år på en gymnasieskola i Kristianstad. Intervjuerna utgick från en intervjuguide och det insamlade materialet analyserades genom en kvalitativ innehållsanalys. Resultatet av studien visade att informanterna upplevde sig ha en god oral hälsa och att de tog väl hand om sina tänder. Det var viktigt för informanterna att ha en god oral hälsa och de beskrev betydelsen både på ett fysiskt och psykiskt plan. Majoriteten av informanterna upplevde att den orala hälsan påverkade livskvalitén. Slutsatsen av studien är att ungdomar tycks uppleva sig ha en god oral hälsa och att upplevda orala problem påverkar livskvalitén. Ungdomar anser att det är viktigt att ha en god oral hälsa och att tändernas utseende är betydelsefullt.

    Relation of gelsolin amyloidosis and periodontal health2015In: Clinical Oral Investigations, ISSN 1432-6981, E-ISSN 1436-3771, Vol. 19, no 2, p. 229-235Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: Hereditary gelsolin amyloidosis (AGel amyloidosis) is a rare, dominantly inherited systemic disease with worldwide distribution, caused by a gelsolin gene mutation. We studied the periodontal conditions and microbiological plaque composition of AGel amyloidosis patients.

    MATERIAL AND METHODS: A voluntary study group of 36 AGel amyloidosis patients (mean age 61) filled in a questionnaire. A thorough periodontal examination included periodontal pocket depth and attachment level measurements, registrations of visible plaque, bleeding on probing and panoramic radiographs. The presence of oral Candida was studied by fungal culture method. Bacterial samples from deepened pockets (≥4 mm) were analyzed with checkerboard DNA-DNA hybridization method.

    RESULTS: VPI (15.3 %) and BOP (11.2 %) of the patients were modest reflecting relatively adequate oral self-care. Still 89 % of the patients had at least one PPD of ≥4 mm; 78.5 % of the PPDs ≥6 mm were found in molars. Patients had lost one third of the molars due to periodontitis and/or tooth decay. Half of the patients (53 %) were Candida carriers. Bacterial analysis of subgingival plaque samples revealed bacterial species common to chronic periodontitis.

    CONCLUSION: AGel amyloidosis may increase the risk for periodontitis even when the oral self-care is adequate. Molar teeth appear to be mostly affected, leading to tooth loss.

    CLINICAL RELEVANCE: AGel amyloidosis as a systemic disease is related with a vast variety of symptoms with variable severity. Even though a causal relationship of the systemic disease and periodontitis has not yet been proven, increased risk for periodontal problems should be considered when examining AGel amyloidosis patients.

    Association of early onset periodontitis microbiota with aspartate aminotransferase activity in gingival crevicular fluid.2001In: Journal of Clinical Periodontology, ISSN 0303-6979, E-ISSN 1600-051X, Vol. 28, no 12, p. 1096-1105Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: The objective of this study was to determine the relationship between the activity of the enzyme aspartate aminotransferase (AST) in gingival crevicular fluid (GCF) using the colorimetric PerioGard (PTM) test and the subgingival microflora in early onset periodontitis lesions.

    MATERIAL AND METHODS: The study population consisted of 25 otherwise healthy individuals exhibiting early onset periodontitis (EOP). In each patient four experimental sites were identified comprising one deep periodontal pocket (PD >5 mm) randomly chosen in each quadrant. Bacterial samples were obtained from the experimental sites, consecutively cultured anaerobically and in 10% CO(2) using selective and nonselective media. Isolates were characterized to species level by conventional biochemical tests and various identification kits. Clinical measurements as well as AST activity, assessed either as positive or negative using the PTM, were recorded at the same sites.

    RESULTS: Sixty-two sites exhibited AST positive and 38 AST negative activity. Analysis of bacterial counts using the ANOVA (Mann Whitney U-test) showed that Streptococcus intermedius, Peptostreptococcus micros, Campylobacter concisus, Bacteroides forsythus, Camplobacter gracilis, Campylobacter rectus and Selenomonas sputigena were significantly higher in sites with AST-positive activity. The odds ratio of having high prevalence of S. intermedius, P. micros, C. concisus, B. forsythus, C. gracilis, C. rectus and S. sputigena in the presence of a positive AST site was very high (range: 3.5-17.0). Streptococcus sanguis, Actinomyces naeslundii, Gemella morbillorum, Capnocytophaga gingivalis, Veillonella parvula, Fusobacterium varium, Eubacterium lentum and Prevotella oralis were detected in significantly higher proportions in sites with AST negative activity and manifested a negative odds ratio in the presence of AST positive sites. The logistic regression analysis revealed that smoking and bleeding upon probing showed a significant association with AST activity, while plaque and suppuration were not found to be significant predictors of AST activity. The co-infection of Porphyromonas gingivalis, B. forsythus and P. micros, or P. gingivalis, B. forsythus and C. rectus were found to be significantly associated with the AST activity (p<0.001). AST positive sites revealed significantly higher occurrence of co-infections by P. gingivalis, B. forsythus, S. sputigena or by P. gingivalis, B. forsythus, S. intermedius than AST negative sites (p<0.001). P. gingivalis, B. forsythus, A. naeslundii co-infection was found significantly higher in the AST negative sites (p<0.001).

    CONCLUSIONS: The present study found a high level of agreement between the presence of putative periodontal pathogens and positive AST scores at periodontal sites that clinically were considered to be potentially disease active. Prospective studies should be performed to confirm the findings.

    Randomized controlled trial: lip piercing: the impact of material on microbiological findings2013In: Pediatric dentistry, ISSN 1942-5473, Vol. 35, no 1, p. 23E-28EArticle in journal (Refereed)
    Abstract [en]

    PURPOSE: The purpose of this study was to investigate whether there are microbiological differences in bacterial samples collected from labial piercings made of different materials.

    METHODS: Sterile piercings of 4 materials were randomly allocated to 80 pierced subjects. After 2 weeks, microbiologic samples were collected and processed by checkerboard DNA-DNA hybridization methods. Wilcoxon signed ranks and Mann-Whitney tests were used for statistical analysis (adjustment for multiple comparisons).

    RESULTS: There were no statistically significant differences between material groups in relation to baseline data. In samples from stainless steel piercings, the total microbial load was significantly higher than the other materials (P<.05). Ten (mainly periopathogenic) species were found at significantly higher levels (P<.001) on steel than on polypropylene and/or polytetrafluoroethylene piercings.

    CONCLUSIONS: Labial piercings made of stainless steel could promote the development of a pathogenic biofilm.

    Tongue piercing: the effect of material on microbiological findings.2011In: Journal of Adolescent Health, ISSN 1054-139X, E-ISSN 1879-1972, Vol. 49, no 1, p. 76-83Article in journal (Refereed)
    Abstract [en]

    PURPOSE: Biofilms on oral piercings may serve as a bacterial reservoir and lead to systemic bacteremia or local transmission of pathogenic microbiota. The use of piercing materials which are less susceptible to biofilm accumulation could contribute to prevention of problems. The present study investigated whether there are microbiological differences in bacterial samples collected from tongue piercings made of different materials.

    METHODS: A total of 85 subjects with tongue piercings participated in this study. After a baseline dental examination, sterile piercings of four different materials were randomly allocated to the study subjects. After 2 weeks, microbiologic samples were collected and processed by checkerboard deoxyribonucleic acid- deoxyribonucleic acid hybridization methods.

    RESULTS: About 28.8% of subjects reported 61 lingual recessions (1.91 ± .96 mm), whereas 5% reported tooth chipping on one tooth each. With the exception of Aggregatibacter actinomycetemcomitans (Y4), Fusobacterium nucleatum species, and Parvimonas micra, bacteria associated with periodontitis were not commonly found in the samples from studs or piercing channels. Of the 80 bacterial species, 67 were found at significantly higher levels (p < .001) in samples from stainless steel than from polytetrafluoroethylene or polypropylene piercings.

    CONCLUSION: The low bacterial counts from piercing channels suggest that having a tongue pierced would not contribute to an increased risk for oral infection. The present study demonstrated that studs made of steel might promote the development of a biofilm, whereas those made of polytetrafluoroethylene or polypropylene may be rather inert to bacterial colonization. The finding of Staphylococci on steel and titanium studs may suggest an elevated risk for complication if the piercing channel is infected.

    Impact of sample storage on detection of periodontal bacteria.2005In: Oral Microbiology and Immunology, ISSN 0902-0055, E-ISSN 1399-302X, Vol. 20, no 2, p. 128-130Article in journal (Refereed)
    Abstract [en]

    BACKGROUND/AIMS: Information on the impact of sample storage prior to analysis by DNA methods is limited. The aim of this study was to investigate the effect of subgingival sample storage on bacterial detection and enumeration.

    MATERIAL AND METHODS: Subgingival plaque samples were studied by a) checkerboard DNA-DNA hybridization by immediate processing, b) storage at + 4 degrees C for 6 weeks, c) storage at - 20 degrees C for 6 months or d) storage at - 20 degrees C for 12 months.

    RESULTS: No differences in total DNA were found between protocol 1 and 2, or between protocol 3 and 4. Protocol 1 yielded 2.4 times more total bacterial DNA than did protocol 3 (P < 0.001). Actinobacillus actinomycetemcomitans and Campylobacter gracilis were detected in 21.1% of the immediately processed samples but only in 6.6% of the samples after 12 months of storage. Similar changes were noticed for Treponema denticola, which was detected in 22.3% and 9.2%, respectively. Streptococci spp., Fusobacterium nucleatum and Tannerella forsythia did not seem to be affected by storage. In contrast, the level of Campylobacter rectus detection frequency changed from 2.6% if processed immediately to 15.8% if samples were stored for 12 months.

    CONCLUSIONS: In longitudinal clinical studies including microbiological samples and processed with DNA-DNA hybridization methods, samples should be stored for the same period of time before processing to avoid loss of microbiological information.

    Den orala hälsans påverkan hos barn med övervikt2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Obesity is a growing, global health problem. Last year (2010) there were more than 43 million overweight children (under the age of five) in the world. The aim of this study was to determine if oral health is affected in overweight children. The authors chose to study publications regarding oral health in overweight children between the ages of 2-19 years. The material was collected from the medical databases PubMed and Science Direct. These results are based on seventeen scientific medical reports.

    Several studies show that overweight children have more decayed teeth and a greater risk for developing caries than children with normal weight. A small number of studies found a correlation between fewer decayed teeth and overweight children compared to children with normal weight. Another result showed an association between obesity in children that can lead to early tooth eruption and a greater risk for developing periodontitis after the age of 16.

    More research is required to determine associations between obesity in children and its connections to oral health conditions. It is important for dentists and dental hygienists to be alert to child patients with obesity, as they might have an increased risk for caries, periodontitis and early tooth eruption.

    Clinical and microbiological findings at sites treated with orthodontic fixed appliances in adolescents.2010In: American Journal of Orthodontics and Dentofacial Orthopedics, ISSN 0889-5406, E-ISSN 1097-6752, Vol. 137, no 2, p. 223-228Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: Fixed orthodontic appliances can alter the subgingival microbiota. Our aim was to compare the subgingival microbiota and clinical parameters in adolescent subjects at sites of teeth treated with orthodontic bands with margins at (OBM) or below the gingival margin (OBSM), or with brackets (OBR).

    METHODS: Microbial samples were collected from 33 subjects (ages, 12-18 years) in treatment more than 6 months. The microbiota was assessed by the DNA-DNA checkerboard hybridization method.

    RESULTS: Bacterial samples were taken from 83 OBR,103 OBSM, and 54 OBM sites. Probing pocket depths differed by orthodontic type (P <0.001) with mean values of 2.9 mm (SD, 0.6) at OBSM sites, 2.5 mm (SD, 0.6) at OBM sites, and 2.3 mm (SD, 0.5) at OBR sites. Only Actinomyces israelii (P <0.001) and Actinomyces naeslundii (P <0.001) had higher levels at OBR sites, whereas Neisseria mucosa had higher levels at sites treated with OBSM or OBM (P <0.001). Aggregatibacter actinomycetemcomitans was found in 25% of sites independent of the appliance.

    CONCLUSIONS: Different types of orthodontic appliances cause minor differences in the subgingival microbiota (A israelii and A naeslundii) and higher levels at sites treated with orthodontic brackets. More sites with bleeding on probing and deeper pockets were found around orthodontic bands.

    Caries-related saliva properties in individuals with 22q11 deletion syndrome2007In: Oral surgery, oral medicine, oral pathology, oral radiology, and endodontics, ISSN 1079-2104, E-ISSN 1528-395X, Vol. 103, no 4, p. 497-504Article in journal (Refereed)
    Abstract [en]

    Abstract: Objectives. The aims were to compare saliva secretion rate, buffer capacity, cariogenic bacteria, total protein, IgA, and electrolytes between patients with 22q11 deletion syndrome (22q11DS) and control subjects and to study correlations between saliva and serum levels of IgA and electrolytes in 22q11DS patients.

    Study design. Twenty-nine consecutive 22q11DS patients (mean age 12.6 years) and matched healthy control subjects were clinically examined, and stimulated saliva samples were collected.

    Results. Patients with 22q11DS had impaired salivary secretion rate (P <.01) and buffer capacity (P <.05), higher numbers of cariogenic bacteria (P <.01), increased saliva protein concentrations (P <.001), and reduced output of electrolytes (P <.001 -.05) compared with control subjects. A correlation between concentration in serum and saliva was found only for IgA (r =.622; P<.01).

    Conclusions. Different salivary components were affected in patients with 22q11DS, which may explain the increased caries risk seen in these patients.

    Äldre personers uppfattning av tandhygienistbesök2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det finns en begränsad mängd vetenskapliga studier om äldres uppfattning av tandhygienistbesök. Därför är det viktigt att belysa och få vetskap om vad äldre personer har för uppfattning av tandhygienistbesök för att få en ökad förståelse för denna patientgrupp och deras behov. Syftet med studien var att undersöka äldre personers uppfattning av tandhygienistbesök. Studien är en kvantitativ empirisk studie som utfördes med användning av en enkät som innehöll 22 frågor med fasta svarsalternativ som delades ut vid olika pensionärsföreningar och samlingsplatser. I studien ingick 110 äldre personer från åldern 65 år och däröver. Studien visade att majoriteten av respondenterna uppfattade att tandhygienisten hade ett mycket bra bemötande och att de uppfattade att de hade fått det stöd och den hjälp de behöver för att kunna ha en god munhygien. En stor del av respondenterna var nöjda med det senaste besöket och de trivdes mycket bra hos tandhygienisten. Det var ett mindre antal som uppfattade tandhygienistbesök som obehagliga och smärtsamma. Studiens slutsats visar att majoriteten har en positiv uppfattning av tandhygienistbesök och att de anser att det är viktigt att besöka en tandhygienist.

    The patient undergoing implant therapy: summary and consensus statements: the 4th EAO Consensus Conference 20152015In: Clinical Oral Implants Research, ISSN 0905-7161, E-ISSN 1600-0501, Vol. 26 Suppl 11, p. 64-7Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: The assignment for this working group was to update the existing knowledge regarding factors considered being of special relevance for the patient undergoing implant therapy. This included areas where conflicting opinions exists since long or recently has been expressed, like the role of antibiotic prophylaxis in dental implant surgery and peri-implantitis. Also areas with growing interest and concern such as patient-reported outcome measures (PROMs) and health-economy was included in this review.

    MATERIALS AND METHODS: The literature in the respective areas of interest (antibiotic prophylaxis, peri-implantitis, patient-reported outcome measurements and health-economic aspects) was searched using different strategies for the different papers. Search strategies ranged from a complex systematic review to systematic- and narrative reviews, depending on subject and available literature. All collected material was critically reviewed. Four manuscripts were subsequently presented for group analysis and discussion and plenum discussions and concensus approval. The selected areas were considered to be of key importance and relevance for the patient undergoing implant therapy.

    RESULTS: The results and conclusions of the review process are presented in the respective papers. The group's conclusions, identified knowledge gaps, directions for future research and concensus statements are presented in this article. The following reviews were available for group discussions and the foundation for subsequent plenary sessions: Lund B, Hultin M, Tranaeus S, Naimi-Akbar A, Klinge B.

    Osseointegration on implant surfaces previously contaminated with plaque. An experimental study in the dog2003In: Clinical Oral Implants Research, ISSN 0905-7161, E-ISSN 1600-0501, Vol. 14, no 4, p. 373-380Article in journal (Refereed)
    Abstract [en]

    This study investigated whether osseointegration can occur on a surface which had previously been coated with dental plaque. The mandibular premolar regions of four young adult Labrador dogs were used for the study. The lower premolars (P1, P2, P3, and P4) were extracted on either side of the mandibles. Following a 12-week healing period, three 3.75 mm x 13 mm commercially pure titanium implants (Nobel BiocareAB, Gothenburg, Sweden) were partially inserted in one side of each mandible. This resulted in some threads protruding from the tissues into the oral cavity. Plaque was allowed to accumulate on the exposed implant surfaces. Following a 5-week healing period, the contaminated parts of each implant were treated using three different cleaning techniques: (1) swabbing with supersaturated citric acid for 30 s on a cotton pellet followed by rinsing with physiological saline, (2) cleansing with a toothbrush and physiological saline only for 1 min, and (3) swabbing with 10% hydrogen peroxide (H2O2) on a cotton pellet for 1 min followed by rinsing with physiological saline. The treated implants and one previously unused implant (control) were then placed into freshly prepared tapped sites to the full implant length on the contralateral sides of the mandibles. Following 11 weeks of healing, biopsies were obtained and ground sections prepared for histomorphometric analysis. All treatment modalities were associated with direct bone to implant contact on the portion of implant surface previously exposed to the oral environment. In conclusion, The results demonstrate that osseointegration can occur to surfaces that were plaque contaminated and cleaned by different methods.

    The severity of human peri-implantitis lesions correlates with the level of submucosal microbial sysbiosis2018In: Journal of Clinical Periodontology, ISSN 0303-6979, E-ISSN 1600-051X, Vol. 45, no 12, p. 1498-1509Article in journal (Refereed)
    Abstract [en]

    AIM: To cross-sectionally analyze the submucosal microbiome of peri-implantitis (PI) lesions at different severity levels.

    MATERIALS AND METHODS: Microbial signatures of 45 submucosal plaque samples from untreated peri-implantitis lesions obtained from 30 non-smoking, systemically healthy subjects were assessed by 16s sequencing. Linear mixed models were used to identify taxa with differential abundance by probing depth, after correction for age, gender, and multiple samples per subject. Network analyses were performed to identify groups of taxa with mutual occurrence or exclusion. Subsequently, the effects of peri-implant probing depth on submucosal microbial dysbiosis was calculated using the microbial dysbiosis index.

    RESULTS: In total, we identified 337 different taxa in the submucosal microbiome of peri-implantitis. Total abundance of 12 taxa correlated significantly with increasing probing depth; a significant relationship with lower probing depth was found for 16 taxa. Network analysis identified two mutually exclusive complexes associated with shallow pockets and deeper pockets, respectively. Deeper peri-implant pockets were associated with significantly increased dysbiosis.

    CONCLUSION: Increases in peri-implant pocket depth are associated with substantial changes in the submucosal microbiome and increasing levels of dysbiosis. This article is protected by copyright. All rights reserved.

    Plackavlägsnande effekt: jämförelse mellan manuell och elektrisk tandborste2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Oral health is an important part of overall health and may affect the quality of life. Plaque has an effect on oral health and may be a contributing factor to the development of periodontal diseases and caries. The purpose of this study was to compare the plaque removal efficacy with the use of manual and electric toothbrush. The study was conducted as a review and the material was collected by search of scientific articles in the database Pub Med. Keywords was "dental plaque", "plaque", "dental biofilm", "electric toothbrush", "power toothbrush" and "manual toothbrush". The result was based on 15 scientific articles. Plaque removal efficacy of electric and manual toothbrush was compared in different groups such as patients with fixed orthodontic appliances, patients with periodontitis and gingivitis, dental students, children, youth and adults. The results showed that the electric toothbrush had better plaque removal efficacy than manual toothbrush in all groups.

    The conclusion is that the electric toothbrush has better plaque removal efficiency than a manual toothbrush, which also supports the study's hypothesis.

    Intresset för volontär tandvård bland blivande tandläkare och tandhygienister: en enkätstudie2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Många människor i utvecklingsländer lever dagligen med tandvärk och har aldrig besökt en tandläkare. Tandläkare och tandhygienister som arbetar som volontärer åker iväg för att hjälpa till, skänka glädje och hopp till dessa människor. Syftet med denna studie var att undersöka om det fanns tandläkar- och tandhygieniststudenter som ville arbeta ideellt som volontär inom tandvården i utvecklingsländer efter avslutade studier. Studien genomfördes som en enkätundersökning där enkäterna sändes ut till alla (n= 367) som studerar sitt sista år på tandläkar- och tandhygienistprogrammet i Sverige. Resultatet visade att lite mer än hälften, 106 av 204 respondenter önskade arbeta ideellt som volontär i utvecklingsländer efter avslutade studier. Endast ett fåtal hade någon erfarenhet av ideellt arbete sedan tidigare och den största anledningen till att studenterna ville arbeta som volontärer i utvecklingsländer var viljan att hjälpa till. Det fanns ingen skillnad i svaren beroende på könsfördelning och yrkesgruppering. Slutsatsen med studien är att cirka hälften av de tillfrågade tandläkar - och tandhygieniststudenterna önskade att arbeta ideellt som volontär i utvecklingsländer.

    IL-1RN gene polymorphism is associated with peri-implantitis.2006In: Clinical Oral Implants Research, ISSN 0905-7161, E-ISSN 1600-0501, Vol. 17, no 4, p. 380-385Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: Interleukin (IL)-1alpha, IL-1beta and their natural specific inhibitor IL-1 receptor antagonist (IL-1ra) play a key role in the regulation of the inflammatory response in periodontal tissues. Polymorphisms in the IL-1 gene cluster have been associated with severe adult periodontitis. We aimed to investigate the IL-1 gene cluster polymorphisms in patients with peri-implantitis.

    MATERIAL AND METHODS: The study included 120 North Caucasian individuals. A total of 71 patients (mean age 68 years, 76% smokers) demonstrating peri-implantitis at one or more implants as evidenced by bleeding and/or pus on probing and bone loss amounting to >3 threads on Brånemark implants and 49 controls (mean age 66 years, 45% smokers) with clinical healthy mucosa and no bone loss around the implants were recruited for the study. The titanium implants, ad modum Brånemark, had been in function for at least 2 years. Mouthwash samples were collected and used for genotyping of the bi-allelic polymorphisms IL-1A(-889), IL-1B(+3953), IL-1B(-511) and a variable number of tandem repeat IL-1RN gene polymorphisms using PCR technique.

    RESULTS: Significant differences were found in the carriage rate of allele 2 in the IL-1RN gene between peri-implantitis patients and controls (56.5% vs. 33.3%, respectively; odds ratios (OR) 2.6; 95% confidence interval (CI) 1.2-5.6; P=0.015). Logistic regression analysis taking smoking, gender and age into account confirmed the association between the IL-1RN allele 2 carriers and peri-implantitis (OR 3; 95% CI 1.2-7.6; P=0.02).

    CONCLUSIONS: Our results provide evidence that IL-1RN gene polymorphism is associated with peri-implantitis and may represent a risk factor for this disease.
