    Munhygien- och kostvanor hos gymnasieelever2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte:Syftet med studien var att undersöka munhygien- och kostvanor hos gymnasieelever i årskurs 3. Material och metod: Studien var en kvantitativ tvärsnittsstudie. Datainsamlingen genomfördes i form av enkätundersökning med 123 deltagare i åldrarna 18-22 år. Enkäten bestod av 20 frågor med fasta svarsalternativ som berörde elevernas bakgrund, munhygien- och kostvanor. Resultat: Studiens resultat visade att majoriteten av deltagarna borstade tänderna två gånger om dagen med tandborste och fluortandkräm och 28 % använde något approximalt hjälpmedel. Mer än hälften av deltagarna åt lunch och middag varje dag, däremot var det endast hälften av deltagarna som åt frukost varje dag. Deltagarna hade ett lågt intag av sötsaker. Slutsats: Studien visade att deltagarna hade relativt goda munhygienvanor, däremot var användningen av approximala hjälpmedel och fluorpreparat bristfälliga. Vidare visade resultatet att deltagarna hade bristfälliga kostvanor då endast hälften av deltagarna åt frukost varje dag.

    The effect of a decontamination protocol on contaminated titanium dental implant surfaces with different surface topography in edentulous patients.2018In: Acta Odontologica Scandinavica, ISSN 0001-6357, E-ISSN 1502-3850Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: To investigate if it is possible to achieve complete decontamination of dental implant surfaces with different surface characteristics.

    MATERIALS AND METHODS: Twelve implant pieces with an Osseotite® surface and 12 implant pieces with a Ti-Unite® surface were attached on to the complete lower dentures of six patients and were allowed to accumulate plaque for 30 days. When retrieved, the implant decontamination protocol used, involved both mechanical (PeriBrush™) and chemical (3% H2O2) decontamination. The number of colony forming units per millilitre was determined and the dominant micro-organisms in selected samples was identified by 16s rRNA gene amplicon sequencing. The effect of the titanium brush on the implant surface was examined by SEM.

    RESULTS: Complete decontamination was achieved in five out of 24 implants (four Osseotite® and one Ti-Unite®). The mean CFU/ml detected after decontamination were 464.48 for Osseotite® and 729.09 for Ti-Unite® implants. On the surface of the implants in which complete decontamination was not achieved, all of the predominant bacteria identified were streptococci except for one which was identified as micrococcus. SEM images revealed that the surface features of the decontaminated implants were not significantly altered.

    CONCLUSIONS: Mechanical decontamination using a titanium brush supplemented with chemical treatment for one minute (3% H2O2) can achieve complete decontamination of implant surfaces in edentulous patients.

    Kost och munhygienvanor hos skiftarbetare2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien var att kartlägga kostvanor och munhygienvanor samt uppfattning av den egna munhälsan hos skiftarbetare. Studien har utförts som en kvantitativ tvärsnittsstudie med användning av enkät. Undersökningsgruppen bestod av sammanlagt 100 skiftarbetare från industri- och vård- och omsorgssektorn i Skåne. Det insamlade materialet analyserades i statistikprogrammet Statistical Package for the Social Sciences (SPSS) version 23.0. Resultatet av studien visade att skiftarbetarnas kostvanor påverkades negativt av skiftarbete genom ökat småätande, intag av sötad dryck och oregelbundna måltider på grund av varierande arbetstider.  När det gäller munhygienvanor påverkades inte tandborstningen på samma sätt, däremot rengöringen mellan tänderna utförs inte regelmässigt. Studiens slutsats visade att skiftarbetarna hade goda munhygienvanor när det gäller tandborstning och fluoranvändning dock med mindre regelbunden rengöring mellan tänderna. Kostvanorna var bristfälliga med ökat småätande och sötade drycker mellan måltiderna.

    Peri-implant diseases and conditions: consensus report of workgroup 4 of the 2017 world workshop on the classification of periodontal and peri-implant diseases and conditions2018In: Journal of Clinical Periodontology, ISSN 0303-6979, E-ISSN 1600-051X, Vol. 45, no S20, p. 286-291Article in journal (Refereed)
    Abstract [en]

    A classification for peri-implant diseases and conditions was presented. Focused questions on the characteristics of peri-implant health, peri-implant mucositis, peri-implantitis, and soft- and hard-tissue deficiencies were addressed. Peri-implant health is characterized by the absence of erythema, bleeding on probing, swelling, and suppuration. It is not possible to define a range of probing depths compatible with health; Peri-implant health can exist around implants with reduced bone support. The main clinical characteristic of peri-implant mucositis is bleeding on gentle probing. Erythema, swelling, and/or suppuration may also be present. An increase in probing depth is often observed in the presence of peri-implant mucositis due to swelling or decrease in probing resistance. There is strong evidence from animal and human experimental studies that plaque is the etiological factor for peri-implant mucositis. Peri-implantitis is a plaque-associated pathological condition occurring in tissues around dental implants, characterized by inflammation in the peri-implant mucosa and subsequent progressive loss of supporting bone. Peri-implantitis sites exhibit clinical signs of inflammation, bleeding on probing, and/or suppuration, increased probing depths and/or recession of the mucosal margin in addition to radiographic bone loss. The evidence is equivocal regarding the effect of keratinized mucosa on the long-term health of the peri-implant tissue. It appears, however, that keratinized mucosa may have advantages regarding patient comfort and ease of plaque removal. Case definitions in day-to-day clinical practice and in epidemiological or disease-surveillance studies for peri-implant health, peri-implant mucositis, and peri-implantitis were introduced. The proposed case definitions should be viewed within the context that there is no generic implant and that there are numerous implant designs with different surface characteristics, surgical and loading protocols. It is recommended that the clinician obtain baseline radiographic and probing measurements following the completion of the implant-supported prosthesis.

    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®). 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®. 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® (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® thus showed significant promise in alleviating the impact of diabetes on dental as well as general health.

    The severity of human peri-implantitis lesions correlates with the level of submucosal microbial sysbiosis2018In: Journal of Clinical Periodontology, ISSN 0303-6979, E-ISSN 1600-051XArticle 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.

    Upplevelser av cigarettrökning och uppfattning om dess påverkan på orala hälsan bland en grupp högskolestudenter: en kvalitativ studie2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Syftet med studien var att belysa hur studenter som dagligen röker minst tio cigaretter upplever det egna tobaksbruket. Ett ytterligare syfte var att belysa studenternas uppfattning om cigarettrökningens påverkan på den orala hälsan. Material och metod: En empirisk studie med kvalitativ design tillämpades. Datamaterial samlades in genom intervjuer där åtta studenter från Högskolan Kristianstad deltog. Intervjuerna baserades på en intervjuguide på tolv frågor, som varade i cirka 10-15 minuter. Data analyserades genom kvalitativ innehållsanalys. Resultat: I studiens resultat framgick att deltagarna upplevde lugnande och avslappnande känslor i samband med sin cigarettrökning. Dessa känslor framgick främst vid rökning under stressfulla situationer och var huvudanledningen till att deltagarna fortsatte röka. I samband med sin rökning upplevde majoriteten av deltagarna försämrad kondition och svårigheter att vara ifrån rökningen i fem timmar eller mer.  Studenternas uppfattningar om hur rökning påverkar oral hälsa var att det medförde främst gula tänder och dålig andedräkt. Slutsats: Studenterna hade en positiv syn på sin cigarettrökning där de upplevde främst avslappnande och lugnande känslor. Deras uppfattningar om rökningens effekter på orala hälsan var bristande där främst missfärgningar och dålig andedräkt framgick.

    Longitudinal evaluation of periodontitis and development of cognitive decline among older adults2018In: Journal of Clinical Periodontology, ISSN 0303-6979, E-ISSN 1600-051X, Vol. 45, no 10, p. 1142-1149Article in journal (Refereed)
    Abstract [en]

    AIM: to determine whether having periodontitis is associated with cognitive decline among older adults.

    MATERIAL AND METHODS: A prospective population study of older adults, Swedish National Study on Ageing and Care, (SNAC) provided repeated registrations of cognitive functions. Cognitive decline was defined as ≥ 3-points deterioration from a predetermined level at baseline, using the Mini-Mental State Examination (MMSE). Between 2001 and 2003, 715 individuals had a medical as well as a clinical and radiographic dental examination. The individuals were re-examined after 6 years. Periodontitis was defined as ≥ 4mm bone loss at ≥ 30% of tooth sites. Social variables were captured from questionnaires.

    RESULTS: The multivariate logistic regression analysis demonstrated a statistically significant association between prevalence of periodontitis and cognitive decline after adjustments of confounding factors of importance.

    CONCLUSIONS: A history of periodontitis may be of importance for cognitive functions among older adults. This article is protected by copyright. All rights reserved.

    Occurrence of cases with peri-implant mucositis or peri-implantitis in a 21-26 years follow-up study2018In: Journal of Clinical Periodontology, ISSN 0303-6979, E-ISSN 1600-051X, Vol. 45, no 2, p. 233-240Article in journal (Refereed)
    Abstract [en]

    AIM: to determine the prevalence and development of peri-implant mucositis and peri-implantitis and to assess risk factors over time.

    MATERIALS AND METHODS: The study is a longitudinal case series assessing the occurrence and diagnosis of peri-implant mucositis and peri-implantitis.

    RESULTS: 218/294 patients who had received dental implants between 1988-1992 were examined between 2000-2002 (exam II; 9-14 years after the first exam). At exam III (20-26 years after exam I, on average 23.3 years), 86 individuals were re-examined. The diagnosis of peri-implant mucositis and peri-implantitis at exam III was 23.8% and 13.7% respectively. Surgical treatment of peri-implantitis after exam II resulted in a bone gain for 2/12 individuals. Individuals with ≥ 3 implants at exam II were at risk for peri-implantitis at exam III (χ2=7.9, p <0.01, LR: 11.6, 95%CI: 1.5, 92.5, p < 0.01). A history of periodontitis (p=0.07), a diagnosis of peri-implant mucositis (p =0.77), or smoking (p=0.86) at exam II, were not predictive of peri-implantitis at exam III.

    CONCLUSIONS: The diagnosis and occurrence of peri-implantitis and peri-implant mucositis was high. Healthy conditions at implants after 9-14 years were predictive of future implant health. This article is protected by copyright. All rights reserved.

    Peri-implant health, peri-implant mucositis, and peri-implantitis: case definitions and diagnostic considerations2018In: Journal of Clinical Periodontology, ISSN 0303-6979, E-ISSN 1600-051X, Vol. 45 Suppl 20, p. 278-285Article in journal (Refereed)
    Abstract [en]

    The objective of this review is to identify case definitions and clinical criteria of peri-implant healthy tissues, peri-implant mucositis, and peri-implantitis. The case definitions were constructed based on a review of the evidence applicable for diagnostic considerations. In summary, the diagnostic definition of peri-implant health is based on the following criteria: 1) absence of peri-implant signs of soft tissue inflammation (redness, swelling, profuse bleeding on probing), and 2) the absence of further additional bone loss following initial healing. The diagnostic definition of peri-implant mucositis is based on following criteria: 1) presence of peri-implant signs of inflammation (redness, swelling, line or drop of bleeding within 30 seconds following probing), combined with 2) no additional bone loss following initial healing. The clinical definition of peri-implantitis is based on following criteria: 1) presence of peri-implant signs of inflammation, 2) radiographic evidence of bone loss following initial healing, and 3) increasing probing depth as compared to probing depth values collected after placement of the prosthetic reconstruction. In the absence of previous radiographs, radiographic bone level ≥3 mm in combination with BOP and probing depths ≥6 mm is indicative of peri-implantitis.

    Surgical treatment of peri-implantitis lesions with or without the use of a bone substitute: a randomized clinical trial2018In: Journal of Clinical Periodontology, ISSN 0303-6979, E-ISSN 1600-051X, Vol. 45, no 10, p. 1266-1274Article in journal (Refereed)
    Abstract [en]

    AIM: To assess whether the treatment outcome differed between surgical debridement, with or without a bone substitute.

    MATERIALS AND METHODS: 41 adults with 3 or 4 wall peri-implant bone defects were enrolled in a 1-year RCT. Surgical debridement (control group), or in combination with a bone substitute (Endobon® ) (test group) was performed.

    RESULTS: Radiographic evidence of defect fill (primary outcome) was only significant in the test group (p = 0.004). At year 1, no bleeding on probing (BOP) in the control and test groups were 7/20 (35%) and 10/21 (47.6%), respectively (χ2=0.67, p=0.41). Plaque scores did not differ by study group at baseline (p=0.31), or at year 1 (p=0.08). Mid-buccal soft tissue recession changes did not differ by groups (p=0.76). Successful treatment outcome (defect fill ≥ 1.0 mm, PPD values at implant ≤5 mm, no BOP, and no suppuration was identified in 1/20 (5.0%) control, and 9/21 (42.9%) test individuals (F= 7,9, p <0.01). Number needed to treat analysis identified an absolute risk reduction of 32.8% in benefit of the test procedure. (F= 7,9, p <0.01).

    CONCLUSIONS: Successful treatment outcome using a bone substitute was more predictable when a composite therapeutic endpoint was considered. This article is protected by copyright. All rights reserved.
