    Metoder för tobaksavvänjning2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Patients with tobacco habits visit the dental care regularly, therefore it is well placed to carry out tobacco cessation for those who smoke or use snuff. The purpose of this study was to highlight methods available for tobacco cessation and results of these methods. The authors searched in the database PubMed and was limited to articles published during the last ten years and performed in the dental care. The framework was limited to eight studies which were performed in the dental care. The results showed that there are several different combination methods for tobacco cessation. In three articles, the 5A method was used in combination with nicotine replacement therapy. In other articles five different combination methods with different follow-up times were used. In one of those with

    combined approach two methods are described. In addition a method was used for snuff cessation. The result showed differences in frequency of success to tobacco stop. The best result was shown after twelve months tobacco cessation and a follow up in two of the combination methods and the method for snuff cessation (36%, 25% and 30%). The lowest success rate was 7% after twelve months follow up with one of the 5A methods. The conclusion of the study is that there are few published studies regarding tobacco cessation in the dental care, which are based on evaluation of methods performed among patients. Follow up, counselling and support have essential effects on the result.

    Effect of grafting materials on osseointegration of dental implants surrounded by circumferential bone defects: an experimental study in the dog2008In: Clinical Oral Implants Research, ISSN 0905-7161, E-ISSN 1600-0501, Vol. 19, no 4, 329-334 p.Article in journal (Refereed)
    Abstract [en]

    AIMS: This study was designed to evaluate the effect of gap width and graft placement on bone healing around implants placed into simulated extraction sockets in the mandibles of four beagle dogs. MATERIALS AND METHODS: Four Ti-Unite implants (13 mm x 3.3 mm) were placed on each side of the mandible. Three implants were surrounded by a 1.35 mm circumferential and a 5 mm deep gap around the coronal portion of the implants. A fourth implant was inserted conventionally into both sides of the mandibles as a positive control. The gaps were filled with either Bio-Oss, autogenous bone or with a blood clot alone. The study design was balanced for animal, side and modality. Ground sections were prepared from biopsies taken at 3 months, and computer-aided histometric measurements of bone/implant contact and area of bone within threads were made for the coronal 5 mm. Data were analysed using analysis of variance. RESULTS: The mean bone/implant contact was 9.8 mm for the control and ranged from 9.3 to 11.3 mm for the three test modalities. The corresponding values for area within threads were 1 mm(2) and 1-1.2 mm(2). Modality had a significant effect on both bone/implant contact (F=16.9; P<0.0001) and area within threads (F=16.7; P<0.0001). CONCLUSION: The results of this study suggest that both autogenous bone graft and Bio-Oss played an important role in the amount of hard tissue fill and osseointegration occurring within marginal bone defects around implants.

    The effect of periodontal therapy on intra-oral halitosis: a case series2016In: Journal of Clinical Periodontology, ISSN 0303-6979, E-ISSN 1600-051X, Vol. 43, no 5, 445-452 p.Article in journal (Refereed)
    Abstract [en]

    Aim: The aim of this study was to evaluate the effects of non-surgical periodontal therapy on intra-oral halitosis 3months after therapy. Material and methods: Sixty-eight adults with intra-oral halitosis were included in a case series. Intra-oral halitosis was evaluated at baseline, and at 3months after treatment using the organoleptic scores (OLS), Halimeter (R), and a gas chromatograph. Results: Significant reductions for OLS (p<0.01), total sum of volatile sulphur compounds (T-VSC) (p<0.01) and methyl mercaptan (MM) (p<0.05) values were found after treatment. Hydrogen sulphide (H2S) levels were not significantly reduced. The numbers of probing pockets 4mm, 5mm and 6mm were significantly reduced as a result of therapy (p<0.001). Bleeding on probing (BOP) and plaque indices were also significantly reduced (p<0.001). For the 34 individuals with successful periodontal treatment (BOP<20% and a 50% reduction of total pocket depth) reductions in OLS (p<0.01) and T-VSC scores (p<0.01) were found. Eleven individuals were considered effectively treated for intra-oral halitosis presenting with a T-VSC value <160ppb, a H2S value <112ppb and a MM value <26ppb. Conclusion: Non-surgical periodontal therapy resulted in reduction of OLS, MM and T-VSC values 3months after therapy. Few individuals were considered as effectively treated for intra-oral halitosis.

    Does pregnancy have an impact on the subgingival microbiota?2009In: Journal of Periodontology, ISSN 0022-3492, Vol. 80, no 1, 72-81 p.Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: We investigated clinical and subgingival microbiologic changes during pregnancy in 20 consecutive pregnant women > or =18 years not receiving dental care.

    METHODS: Bacterial samples from weeks 12, 28, and 36 of pregnancy and at 4 to 6 weeks postpartum were processed for 37 species by checkerboard DNA-DNA hybridization. Clinical periodontal data were collected at week 12 and at 4 to 6 weeks postpartum, and bleeding on probing (BOP) was recorded at sites sampled at the four time points.

    RESULTS: The mean BOP at week 12 and postpartum was 40.1% +/- 18.2% and 27.4% +/- 12.5%, respectively. The corresponding mean BOP at microbiologic test sites was 15% (week 12) and 21% (postpartum; not statistically significant). Total bacterial counts decreased between week 12 and postpartum (P <0.01). Increased bacterial counts over time were found for Neisseria mucosa (P <0.001). Lower counts (P <0.001) were found for Capnocytophaga ochracea, Capnocytophaga sputigena, Eubacterium saburreum, Fusobacterium nucleatum naviforme, Fusobacterium nucleatum polymorphum, Leptotrichia buccalis, Parvimonas micra (previously Peptostreptococcus micros or Micromonas micros), Prevotella intermedia, Prevotella melaninogenica, Staphylococcus aureus, Streptococcus anginosus, Streptococcus intermedius, Streptococcus mutans, Streptococcus oralis, Streptococcus sanguinis, Selenomonas noxia, and Veillonella parvula. No changes occurred between weeks 12 and 28 of pregnancy. Counts of Aggregatibacter actinomycetemcomitans (previously Actinobacillus actinomycetemcomitans), Porphyromonas gingivalis, Tannerella forsythia (previously T. forsythensis), and Treponema denticola did not change. Counts of P. gingivalis and T. forsythia at week 12 were associated with gingivitis (P <0.001).

    CONCLUSIONS: Subgingival levels of bacteria associated with periodontitis did not change. P. gingivalis and T. forsythia counts were associated with BOP at week 12. A decrease was found in 17 of 37 species from week 12 to postpartum. Only counts of N. mucosa increased.

    Comparisons of bacterial patterns present at implant and tooth sites in subjects on supportive periodontal therapy. I. Impact of clinical variables, gender and smoking.2006In: Clinical Oral Implants Research, ISSN 0905-7161, E-ISSN 1600-0501, Vol. 17, no 1, 18-24 p.Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: (I) To compare the oral microflora at implant and tooth sites in subjects participating in a periodontal recall program, (II) to test whether the microflora at implant and tooth sites differ as an effect of gingival bleeding (bleeding on probing (BOP)), or pocket probing depth (PPD), and (III) to test whether smoking and gender had an impact on the microflora.

    MATERIAL AND METHODS: Data were collected from 127 implants and all teeth in 56 subjects. Microbiological data were identified by the DNA-DNA checkerboard hybridization.

    RESULTS: PPD> or =4 mm were found in 16.9% of tooth, and at 26.6% of implant sites (P<0.01). Tooth sites with PPD> or =4 mm had a 3.1-fold higher bacterial load than implant sites (mean difference: 66%, 95% confidence interval (CI): 40.7-91.3, P<0.001). No differences were found for the red, orange, green, and yellow complexes. A higher total bacterial load was found at implant sites with PPD> or =4 mm (mean difference 35.7 x 10(5), 95% CI: 5.2 (10(5)) to 66.1 (10(5)), P<0.02 with equal variance not assumed). At implant sites, BOP had no impact on bacterial load but influenced the load at tooth sites (P<0.01).

    CONCLUSION: BOP, and smoking had no impact on bacteria at implant sites but influenced the bacterial load at tooth sites. Tooth sites harbored more bacteria than implant sites with comparable PPD. The 4 mm PPD cutoff level influenced the distribution and amounts of bacterial loads. The subject factor is explanatory to bacterial load at both tooth and implant sites.

    Microbiological composition associated with interleukin-1 gene polymorphism in subjects undergoing supportive periodontal therapy.2006In: Journal of Periodontology, ISSN 0022-3492, Vol. 77, no 8, 1397-1402 p.Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Interleukin-1 gene polymorphism (IL-1 gene) has been associated with periodontitis. The present study examined the subgingival microbiota by IL-1 gene status in subjects undergoing supportive periodontal therapy (SPT).

    METHODS: A total of 151 subjects with known IL-1 gene status (IL-1A +4845/IL-1B -3954) (IL-1 gene) were included in this study. Clinical data and subgingival plaque samples (40 taxa) were collected. These taxa were determined by the checkerboard DNA-DNA hybridization method.

    RESULTS: Gender, smoking habits (n-par tests), age, and clinical periodontal conditions did not differ by IL-1 gene status. IL-1 gene-negative subjects had a higher total bacterial load (mean difference, 480.4 x 10(5); 95% confidence interval [CI], 77 to 884 x 10(5); P <0.02). The levels of Actinobacillus actinomycetemcomitans (mean difference, 30.7 x 10(5); 95% CI, 2.2 to 59.5 x 10(5); P <0.05), Eubacterium nodatum (mean difference, 4.2 x 10(5); 95% CI, 0.6 to 7.8 x 10(5); P <0.02), Porphyromonas gingivalis (mean difference, 17.9 x 10(5); 95% CI, 1.2 to 34.5 x 10(5); P <0.05), and Streptococcus anginosus (mean difference, 4.0 x 10(5); 95% CI, 0.2 to 7.2 x 10(5); P <0.05) were higher in IL-1 gene-negative subjects, an observation specifically found at sites with probing depths <5.0 mm.

    CONCLUSIONS: Bleeding on probing did not differ by IL gene status, reflecting clinical SPT efficacy. IL-1 gene-negative subjects had higher levels of periodontal pathogens. This may suggest that among subjects undergoing SPT, a lower bacterial load is required in IL-1 gene-positive subjects to develop the same level of periodontitis as in IL-1 gene-negative subjects.

    A single-center randomized controlled clinical trial on the adjunct treatment of intra-bony defects with autogenous bone or a xenograft: results after 12 months2012In: Journal of Clinical Periodontology, ISSN 0303-6979, E-ISSN 1600-051X, Vol. 39, no 7, 666-673 p.Article in journal (Refereed)
    Abstract [en]

    Background Limited evidence exists on the efficacy of regenerative treatment of peri-implantitis Materials and methods Subjects receiving antibiotics and surgical debridement were randomly assigned to placement of autogenous bone (AB) or bovine derived xenograft (BDX) with placement of a collagen membrane. The primary outcome was: evidence of radiographic bone fill and the secondary outcomes included reductions of probing depth (PD) bleeding on probing (BOP) and suppuration. Results 22 subjects were included in the AB and 23 subjects in the BDX group. Statistical analysis failed to demonstrate differences for 38/39 variables assessed at baseline. At 12 months, significant better results were obtained in the BDX group for bone levels (p < 0.001), BOP (p = 0.004), PI (p = 0.003), and suppuration (p < 0.01). When adjusting for number of implants treated per subject, a successful treatment outcome PD≤ 5.0 mm, no pus, no bone loss and BOP at 1/4 sites the likelihood of defect fill was higher in the BDX group (LR: 3.2, 95 % CI: 1.0 to 10.6, p < 0.05). Conclusions Bovine xenograft provided more radiographic bone fill than autogenous bone. The success for both surgical regenerative procedures was limited. Decreases in PD, BOP, and suppuration were observed.

    Evaluation of titanium implants placed into simulated extraction sockets: a study in dogs1999In: International Journal of Oral & Maxillofacial Implants, ISSN 0882-2786, Vol. 14, no 3, 351-360 p.Article in journal (Refereed)
    Abstract [en]

    The purpose of this study was to evaluate the effect of gap width on bone healing around implants placed into simulated extraction socket defects of varying widths in 10 mongrel dogs. All premolars were removed and the alveolar ridges were reduced to a width of 7 mm. Nine weeks later, a total of 80 implants, 10 mm long by 3.3 mm wide, were placed into osteotomy sites prepared to 3 different diameters in the coronal half, simulating extraction sockets. Three experimental sites, with gap sizes of 0.5 mm, 1.0 mm, and 1.4 mm, were created; the control sites had no gap. The depth of each defect was measured at the time of implant placement. All implants were stable at the time of placement. The dogs were euthanized 12 weeks after implant placement, and blocks containing the implants and adjacent bone were submitted for histologic evaluation. Clinically, all control and test sites healed, with complete bone fill in the defect. Percentages of bone-to-implant contact were measured histologically. As the gap widened, the amount of bone-to-implant contact decreased, and the point of the highest bone-to-implant contact shifted apically. These changes were statistically significant (P < .001). No statistically significant differences in bone-to-implant contact were found between the sites when the apical 4 mm of implants were compared. Within the limits of this study, the simulated extraction socket defects healed clinically, with complete bone fill, regardless of the initial gap size. However, the width of the gap at the time of implant placement had a significant impact on the histologic percentage and the height of bone-to-implant contact.

    Re-osseointegration on rough implant surfaces previously coated with bacterial biofilm: an experimental study in the dog2008In: Clinical Oral Implants Research, ISSN 0905-7161, E-ISSN 1600-0501, Vol. 19, no 2, 182-7 p.Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: The purpose of the study was to investigate whether osseointegration can occur on rough implant surfaces that previously had been coated with bacterial biofilm. MATERIALS AND METHODS: The premolars on both sides of the mandible in four beagle dogs were extracted. Following 3 months healing, three titanium implants Ti-Unite, Nobel Biocare were partially inserted in the left side of each mandible. Some threads protruded from the tissues into the oral cavity. Plaque accumulated on the exposed part of the implant. Following a 5-week healing period, the contaminated parts of each implant were treated using three different techniques: (1) swabbing with citric acid for 30 s followed by rinsing with physiological saline, (2) cleansing with a toothbrush and physiological saline for 1 min, and (3) swabbing with 10% hydrogen peroxide for 1 min followed by rinsing with physiological saline. The treated implants and one pristine implant (control) were installed to the full implant length on the contralateral sides of the mandibles. Following 11 weeks of healing, the dogs were sacrificed and biopsies were obtained. Ground sections were prepared for histomorphometric analysis. RESULTS: All treatment modalities were associated with direct bone-to-implant contact on the portion of implant surface previously exposed to the oral environment. CONCLUSIONS: The results demonstrate that rough surfaces, which were plaque contaminated and cleaned by different methods, can re-osseointegrate.

    Klinikchefens uppfattning om tandhygienistens kompetens2010Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    The aim of the study was to examine the competence of dental hygienists among Clinic Director´s within the Public Dental Service and Private dentists in the county of Skåne . The study was quantitative and consisted of an electronic questionnaire sent out to all Clinic Directors in the county of Skåne. A total of five hundred and thirty eight questionnaires were sent out. The inclusion criteria were the Clinic directors who employed dental hygienists who had obtained their professional degree during the last four years. Twenty nine Clinic directors responded to the study.

    The results showed that in general clinic directors are pleased and feel that dental hygienists are proficient in periodontology and dental caries diagnostics. There were two clinic directors who felt that dental hygienists should have more knowledge in the fields of endodontics and pedodontics.

    The Clinic directors were asked if they wanted to add a certain skill or specialty to the competence of dental hygienists. Two of the clinic directors said that they would like to see dental hygienists be able to measure blood and sugar levels if needed.

    In conclusion, this study shows that most of the clinic directors thought that the dental hygienists had good knowledge and skills within their operating range. The result of this study must be interpreted with caution because of the low response rate.

    Assessments of oral health status in frail patients in hospital2004Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The general aims of this thesis were to evaluate the usefulness of an oral assess¬ment guide and to determine the oral health status among frail patients in hospital settings. A further aim was to analyze possible factors that may be associated with oral health status, with special focus on the relationship between oral health and nutritional status among elderly rehabilitation patients. The Oral Assessment Guide (OAG) was used in patients with haematological malignancies undergoing chemotherapy. In further studies a Revised Oral Assessment Guide (ROAG) was used among geriatric rehabilitation patients. The inter-rater reliability of the OAG between registered nurses at the ward and a dental hygienist (DH) was good, as well as between a registered nurse and a DH using ROAG. Problems in the oral cavity were detected in all patients with haematological malignancies undergoing chemotherapy. Problems related to mucous membranes, teeth and/or dentures were most frequent. Oral health problems were also a frequent finding among the geriatric rehabilitation patients. The frequency of oral health problems was significantly lower at discharge compared to admission. Oral health problems were more often found among patients that stayed for longer periods at the hospital, were more dependent on help with daily activities and suffered for dysphagia, than among the healthier patients. Oral health problems were more common among the patients being at risk of undernourishment, suspected to be or severely undernourished (UN), than among the well-nourished patients. Problems in oral health status were significantly associated with the occurrence of respiratory diseases, living in special accommodation, being UN and being a woman. The highest Odds Ratio (OR) was found in problems with gums in relation to the occurrence of respiratory diseases (OR 8.9; 95 % CI 2.8-27.8). OAG as well as ROAG were found to be useful for assessing oral health status in frail patients at hospital. Oral health problems were a frequent finding among the patients. The use of an oral assessment tool on a routine basis may facilitate the detection of problems which otherwise can be hidden, and can serve as a guide for initiating individualised oral health procedures.

    Munhälsostatus hos patienter som vårdas på sjukhus2004In: Tandläkartidningen, ISSN 0039-6982, Vol. 96, no 10, 62-65 p.Article in journal (Other academic)
    Abstract [sv]

    Den 23 april 2004 försvarade tandhygienist Pia Andersson avhandlingen ”Assessments of oral health status in frail patients in hospital” vid odontologiska fakulteten, Malmö högskola. Fakultetsopponent var professor Tony Axéll, Specialisttandvården, Halmstad. Handledare under avhandlingsarbetet har varit professor Stefan Renvert, Högskolan Kristianstad och professor Ingalill Rahm Hallberg, Vårdalinstitutet, Lund. Det övergripande syftet med avhandlingen var att utvärdera ett formulär för att bedöma munhälsan på patienter som låg inne på sjukhus och att undersöka förekomsten av problem i munnen. På äldre patienter inom rehabilitering undersöktes dessutom om det fanns samband mellan munhälsostatus och relaterade faktorer som ålder, kön, boendeform, civilstånd, sjukdomsorsak vid inskrivning till avdelningen, läkemedelsintag, funktionsstatus och nutritionsstatus med fokus på sambandet mellan munhälsostatus och nutritionsstatus.

    Psychometric properties of the Dental Hygienist Anxiety Scale in a group of general dental patients2013In: Acta Odontologica Scandinavica, ISSN 0001-6357, Vol. 71, no 3-4, 877-882 p.Article in journal (Refereed)
    Abstract [en]

    Objective.  The aim of the present study was to evaluate the psychometric properties of the Dental Hygienist Anxiety Scale (DHAS) in a sample of adult general dental patients.  Materials and methods.  The DHAS is a questionnaire adapted to assess fear and anxiety of dental hygienist (DH) treatment. The DHAS contains four items and the sum of scores range from 4 (no anxiety) to 20 (extreme fear). A convenient sample of 80 patients in treatment at two DH programs in Sweden were consecutively included in the study. The DHAS was distributed together with questions regarding self-perceived oral health and experience of dental care at the first visit after a clinical examination performed by a DH. Re-test assessments of DHAS were conducted ∼ 2 weeks later in conjunction with the next visit to the DH before treatment (scaling session).  Results.  The results verified a significant positive correlation between the average DHAS sum of scores and global fear of DH and dentist treatment, perceived pain during the last DH treatment and female gender. The DHAS sum of scores had a high internal consistency, Cronbach's  coefficient of 0.89 and 0.87 at the first and at the second assessment, respectively. The test-re-test reliability of the DHAS sum of scores was acceptable, with an intra-class coefficient of 0.82 and Kappa coefficients between 0.49-0.78 for the four single items in the DHAS. Conclusions.  These results suggest that the DHAS has acceptable psychometric proprieties and is a valid and reliable scale to assess anxiety in DH treatment.

    Clinical correlates of oral impacts on daily performances2010In: International Journal of Dental Hygiene, ISSN 1601-5029, E-ISSN 1601-5037, Vol. 8, no 3, 219-226 p.Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: The aim of this study was to investigate the associations between oral health measures and oral health-related quality of life as captured by OIDP (oral impacts on daily performances).

    METHODS: The study was performed in three dental clinics in Sweden and included 204 patients, 43.8% men and 56.2% women (aged 20-86 years), consecutively recruited in connection with their routine dental examination. The patients were interviewed using the OIDP followed by a clinical examination. Four bite-wing radiographs were taken in two of the clinics (n = 154). A self-administered questionnaire provided information about socio-economic data.

    RESULTS: Subjects >or=60 years had significantly more missing teeth, lesser maximal jaw opening, higher number of sites with alveolar bone loss and proportionally more filled teeth than younger individuals. Impacts related to the oral health that affected their daily life were reported in 39.7%. Multivariate logistic regressions analysis showed that missing teeth (>or=10) and a limited jaw opening (<40 mm) were significantly associated with having one or more impact as measured with the OIDP [odds ratio (OR) 6.50, 95% CI 1.48-28.43 and OR 2.87, 95% CI 1.03-7.96, respectively].

    CONCLUSIONS: Individuals with diminished functional oral health status (missing teeth and limited jaw opening) had significantly more often one or more oral impacts on daily life than those with fewer than 10 missing teeth and a jaw opening >or=40 mm. The OIDP instrument may be valuable for use in routine dental check-ups in patients with related problems to determine possible oral impacts on daily life.

    Dental patients' perceptions and motivation in smoking cessation activities2016In: Acta Odontologica Scandinavica, ISSN 0001-6357, E-ISSN 1502-3850, Vol. 74, no 4, 285-290 p.Article in journal (Refereed)
    Abstract [en]

    Objective

    The aim of the present study was to investigate smokers' perceptions of and motivation for smoking cessation activities in dentistry.

    Materials and methods

    Patients who smoked were consecutively recruited from general as well as specialist dental care clinics in Sweden. After a dental visit the patients completed a questionnaire about self-perceived oral health, smoking habits, motivation, reasons to quit and not to quit smoking, support to quit, smoking cessation activities and questions about smoking asked by dentists and dental hygienists.

    Results

    The sample consisted of 167 adult patients (≥ 20 years) who smoked daily. During the last 6 months, 81% of the patients had experienced oral health problems. The most common complaints were discolourations of the teeth, periodontal problems and dry mouth (38%, 36% and 33%, respectively). Improved general health was a major reason to quit smoking (89%). It was also stated that it was important to avoid oral health problems. 71% of the patients preferred to quit by themselves and 16% wanted support from dentistry. High motivation to quit smoking was reported by 20%. Occurrence of periodontitis during the last 6 months was significantly associated with being highly motivated to stop smoking (OR = 3.0, 95% CI = 1.03-8.55).

    Conclusions

    This study revealed that, although it was important to quit smoking to avoid oral health problems, the patients were not aware that tobacco cessation activities can be performed in dentistry. Periodontal problems seem to be the most motivating factor among the patients who were highly motivated to stop smoking.

    Testing an oral assessment guide during chemotherapy treatmen in a Swedish care setting: a pilot study1999In: Journal of Clinical Nursing, ISSN 0962-1067, E-ISSN 1365-2702, Vol. 8, no 2, 150-158 p.Article in journal (Refereed)
    Abstract [en]

    Oral complications are common in patients with haematological malignancies who undergo chemotherapy treatment. A pilot study including 16 haematological patients was carried out to evaluate the oral status using an Oral Assessment Guide (OAG) and to test the reliability of the OAG. The oral assessments were made daily by registered nurses at a Department of Internal Medicine in Sweden. Once a week a dental hygienist made the oral assessments independent of the registered nurses in order to provide data for calculations of inter-rater reliability. All patients had varying degrees of alterations in the oral cavity, especially in the mucous membranes, teeth/dentures and gums. The inter-rater agreement between the nurses and the dental hygienist was good for saliva and swallow, and moderate for voice and gums. Assessments to detect alterations in the oral cavity afford the opportunity for early and individualized interventions and may decrease the risk of oral infections. It is necessary to train the nurses to ensure high levels of reliability in the oral assessments. The OAG seems to be a reliable and clinical useful tool for assessing the oral cavity status and determining changes.

    Oral health problems in elderly rehabilitation patients2004In: International Journal of Dental Hygiene, ISSN 1601-5029, E-ISSN 1601-5037, Vol. 2, no 2, 70-77 p.Article in journal (Refereed)
    Abstract [en]

    A combination of poor oral hygiene and dry mouth may be hazardous to the oral health status. However, systematic assessments in order to detect oral health problems are seldom performed in the nursing care of the elderly. The aims of this study were to investigate the occurrence of oral health problems measured using the Revised Oral Assessment Guide (ROAG) and to analyse associations between oral health problems and age, gender, living conditions, cohabitation, reason for admission, number of drugs, and functional and nutritional status. One registered nurse performed oral health assessments using ROAG in 161 newly admitted elderly patients in rehabilitation care. Oral health problems were found in 71% of the patients. Thirty per cent of these patients had between four and eight problems. Low saliva flow and problems related to lips were the most frequent oral health problems. Problems in oral health status were significantly associated with presence of respiratory diseases (problems with gums, lips, alterations on the tongue and mucous membranes), living in special accommodation (low saliva flow, problems with teeth/dentures and alterations on the tongue), being undernourished (alterations on the tongue and low saliva flow) and being a woman (low saliva flow). The highest Odds ratio (OR) was found in problems with gums in relation with prevalence of respiratory diseases (OR 8.9; confidence interval (CI) 2.8–27.8; P < 0.0005). This study indicates the importance of standardised oral health assessments in order to detect oral health problems which can otherwise be hidden when the patients are admitted to the hospital ward.

    Comparison of oral health status on admission and discharge in a group of geriatric rehabilitation patients2003In: Oral Health and Preventive Dentistry, Vol. 1, no 3, 221-228 p.Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to compare oral health status on a geriatric rehabilitation ward among patients who were assessed using the Revised Oral Assessment Guide (ROAG) on admission and at discharge; and to investigate in what respect the oral health procedures (OHP) suggested in ROAG were applied when oral health problems were detected. MATERIALS AND METHODS: Registered nurses on the ward performed oral health assessments using ROAG with 107 patients on admission and at discharge. When oral health problems were detected measures to be taken were suggested using ROAG. RESULTS: Oral health problems were common among the patients on admission (86%), as well as at discharge (51%). The frequency of the problems was significantly lower at discharge compared to admission. The OHP that were recommended in ROAG were completely followed when saliva flow-related problems were detected. Regarding other oral health problems, measures other than the recommended ones were often performed. CONCLUSION: This study demonstrated that the oral health was better at the end of the hospital stay compared to admission.

    Inter-rater reliability of an oral assessment guide för elderly patients residing in a rehabilitation ward2002In: Special Care in Dentistry, ISSN 0275-1879, Vol. 22, no 5, 181-186 p.Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to test the inter-rater reliability of a revised oral assessment guide (ROAG) for patients residing in a geriatric rehabilitation ward. A consecutive sample of 140 patients was recruited for the study. Oral assessments were performed for 133 newly admitted patients by one registered nurse (RN) during a period of six months. A dental hygienist (DH) carried out 103 oral assessments during the same half-year. For 66 patients, the RN and the DH performed independent assessments. There was an agreement between the RN and the DH in the majority of the independent assessments, except for tongue and teeth/dentures. The percentage agreement exceeded 80 percent. Inter-rater agreement measured by Cohen's Kappa coefficient ranged from moderate to very good and percentage agreement had a range of 58 to 91 percent. The agreement was highest in assessment of voice and swallowing (91%). Assessments of teeth and dentures seemed to be most difficult for the RN to evaluate. ROAG was found to be a clinically useful assessment tool. Additional education and training is needed to improve the reliability of the oral assessments and should include continuous support from a dental hygienist as well as a pictorial manual on how to use the ROAG.

    Oral health and nutritional status in a group of geriatric rehabilitation patients2002In: Scandinavian Journal of Caring Sciences, ISSN 0283-9318, E-ISSN 1471-6712, Vol. 16, no 3, 311-318 p.Article in journal (Refereed)
    Abstract [en]

    The aims of this study were to evaluate the oral health status and nutritional status in a group of geriatric rehabilitation patients, and to analyse the relationship between these two parameters. Nurses at the ward performed structured assessments of oral and nutritional status using the Revised Oral Assessment Guide and the Subjective Global Assessment form in 223 newly admitted patients. Most oral health problems were found among patients who stayed longer at the hospital and were more dependent on help as compared with the healthier patients. Thirty-four per cent of the patients were either severely undernourished, at risk or suspected to be undernourished (UN). Oral health problems were more common among UN patients (p < 0.0005) compared with well-nourished patients. The most frequent oral health problem was found on teeth or dentures (48%). Problems related to the tongue and lips were also common among UN patients (56 and 44%, respectively). Oral health status was correlated (r = 0.32) to nutritional status. Problems with swallowing had the strongest association to the nutritional status (OR 6.05; 95% CI 2.41-15.18). This study demonstrated that poor oral health status was related to undernourishment.

    Munvård inom vård och omsorg2006Collection (editor) (Other (popular science, discussion, etc.))
    Abstract [sv]

    Munvård är en viktig men ofta eftersatt del av vård och omsorg. Allt fler människor behåller sina naturliga tänder långt upp i åldrarna, vilket medför att behovet av hjälp med munvård ser annorlunda ut idag jämfört med för ett par decennier sedan.

    Boken ger kunskap om den friska munhålan, de vanligaste sjukdomarna samt hur man kan förebygga och behandla dessa. Den beskriver också undersökning av munnen och hur fynden dokumenteras. Andra ämnen som tas upp är munhälsa och nutrition, munvård för patienter med cancer och andra sjukdomstillstånd samt etik och bemötande.

    Munvård ger en god teoretisk grund och lämpar sig särskilt väl för sjuksköterskestudenter och andra inom vård- och omsorgsutbildningarna samt för redan yrkesverksamma inom området.

    Självupplevd oral hälsa hos patienter som strålats mot huvud- och halscancer2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study was to illustrate how patients radiated against head and neck cancer, experience their oral health after ending radiotherapy. The study is qualitative and considers interviews with eight informants. The interviews were conducted using an interview guide. The interviews were recorded on a tape recorder and lasted about 10-20 minutes. The interview data were then analysed using a qualitative content analysis. The results of this study show that a majority of the respondents experience their oral health negatively after ending radiotherapy; these are mentioned in physical effect and mental limitation. The informants experienced pain and dry mouth after completing radiotherapy. The results also showed that they had trouble eating, including swallowing and chewing difficult and that they were forced to make dietary changes. The informants experienced generally it was hard to eat at large surroundings because the fear of choking occurred. Radiotherapy had also affected the informants psychologically, as they often was in low mood. The conclusion of the study shows that these patients experience pain, have trouble eating and that they are affected psychologically as well as inhibited socially.

    Abstract [en]

    The aim of this study was to describe non-surgical treatment options for the diseases mucositis and peri-implantitis found in present literature. The literature review also illustrates the effect of the treatment opptions on soft tissue with mucositis and peri-implantitis surrounding dental implants. The study reviews twelve scientific articles that have been processed from the aim of the study. The result shows six therapy options, Er:YAG laser, air abrasive, ultrasonic device, hand instruments, hand instruments in combination with antibiotics and hand instruments in combination with clorhexidin. The following methods are described according to how they are used and how they affect the soft tissue surrounding dental implants. The therapy options showed some improvements with reduced pocket depth, bleeding on probing (BOP) and gain in clinical attachment level (CAL). Several studies accentuate the importance of good self-care and regular visits for supportive care which have an impact on the survival of the implants and in avoiding progress of disease. All of the therapy options have positive effects but to different extent and it is not concluded how long the positive effect remains in the soft tissue.

    Oral hälsa hos barn med och utan astma2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Asthma is a chronic inflammatory airway disease which is common in all ages. Over 300 million people worldwide are estimated to have the disease.

    Aim: The aim of this study was to investigate whether the oral health differs between children with and without asthma.

    Method: The method used was a literature review and the literature searches were made in the medical database PubMed. The results were based on a compilation of 13 clinical scientific studies and 11 of these compared children with and without asthma. The remaining articles studied either how the oral health was affected by the combination treatment with specific drugs or compared the oral health of children with different duration and medication for asthma.

    Results: Some of the included studies found that children with asthma had an increased cariesprevalence compared with children without asthma, while other studies showed that there was no difference between the groups. Regarding the plaque, bleeding and caries-related bacteria, the results were also conflicting. Medication with β2-agonist combined with corticosteroids contributed to a reduced salivary flow and an increased level of caries-related bacteria among children with asthma.

    Conclusion: There are conflicting results regarding whether the oral health differs between children with and without asthma. Combination treatment with β2-agonists and corticosteroids contributed to a reduced salivary flow and an increased level of caries-related bacteria.

    Abstract [en]

    Chronic obstructive pulmonary disease (COPD) is a chronic lung disease. The disease is the fourth leading cause of death and more than 5 percent of the adult population worldwide is affected.

    The aim of this study was to investigate the association between periodontitis and COPD.

    Search for material for the literature review was done in the medical database PubMed where the keywords were: "Chronic obstructive pulmonary disease" and "Periodontal health or periodontal disease". The result is based on twelve studies that were extracted and analyzed. The studies have investigated pocket depth, attachment loss, plaque index, bleeding on probing and bone loss. Ten studies compared a COPD group with a healthy control group, one study compared two COPD groups and one study examined a COPD group and a group with other lung diseases.

    Most studies found that people with COPD had a higher incidence of pocket depth, attachment loss, plaque index, bleeding on probing and bone loss. The conclusion of the literature review is that there is an association between periodontitis and COPD and that smoking is a link between the two diseases.

    Uptake and release of fluoride from fluoride-impregnated chewing sticks (miswaks) in vitro and in vivo2008In: Caries Research, ISSN 0008-6568, Vol. 42, no 5, 363-368 p.Article in journal (Refereed)
    Abstract [en]

    The purpose was to investigate the uptake and release of fluoride (F) from F-impregnated chewing sticks (miswaks). In the first series, 3-cm-long pieces were impregnated in 1, 2, 3 and 4% NaF solutions for 3 h, 1 day and 3 days (10 pieces/test). There was a dose-response effect with respect to both impregnation time and the concentration of the F solution. In the second and third series, totally 40 miswak pieces were impregnated in 3% NaF for 1 day and 3 days; the outer layer (bark) was separated from the inner spongy part (pulp) and analyzed separately. F was released from both parts, but somewhat more was released from the bark than from the pulp; a plateau was reached at around 30 min. In vivo, 9 healthy subjects used three products for 2 min in a crossover design: (1) a miswak impregnated in 3% NaF for 1 day, (2) a miswak impregnated in 3% NaF for 3 days, and (3) 1 g of F toothpaste (containing 1,450 ppm F as NaF) on a toothbrush. The highest F concentration at the approximal area was obtained after using the miswak impregnated in 3% NaF for 3 days compared with the other products (p < 0.05 or p < 0.01). To conclude, NaF-impregnated miswaks produced a rapid release of F in vitro as well as in vivo and may be an interesting vehicle for home care use for caries prevention in countries where they are used regularly.

    Undersköterskors uppfattning om oral hälsa och munvård på cancerpatienter: en kvalitativ studie2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien var att belysa undersköterskors uppfattning om oral hälsa ochmunvård som utförs på inneliggande cancerpatienter.En kvalitativ studie har tillämpats med en intervjuguide som underlag. Åtta informanterintervjuades i anslutning till deras arbetsplats och intervjuerna varade 10-20 minuter.För att analysera intervjumaterialet användes en kvalitativ innehållsanalys.Resultatet redovisas utifrån temat ”oral hälsa hos cancerpatienter viktigt men lågtprioriterat”. Att hjälpa patienterna med den dagliga munhygienen, upplevde inteinformanterna som något obehagligt utan såg det som en självklar del i sin yrkesroll.Informanterna upplevde även att den orala hälsan inte prioriterade och att det var svårtatt utföra munvård när patienterna nekade hjälp.Studiens slutsats visar att informanterna uppfattar den orala hälsan som en viktig del förpatientens välbefinnande men att munvård inte är det första som prioriteras hoscancerpatienter.

    The effect of permanent grafting materials on the preservation of the buccal bone plate after tooth extraction: an experimental study in the dog2012In: Clinical Oral Implants Research, ISSN 0905-7161, E-ISSN 1600-0501, Vol. 23, no 8, 911-917 p.Article in journal (Refereed)
    Abstract [en]

    Objectives: The aim of the present study was to evaluate the effects of a novel bone substitute system (Natix®), consisting of porous titanium granules (PTG) and a bovine-derived xenograft (Bio-Oss®), on hard tissue remodelling following their placement into fresh extraction sockets in dogs. Material and methods: Six modalities were tested; Natix® granules with and without a covering double-layered Bio Gide® membrane; Bio-Oss® with and without a covering double-layered Bio Gide® membrane; and a socket left empty with and without a covering double-layered Bio Gide® membrane. Linear measurements, indicative of buccal bone height loss, and an area measurement indicative of buccal bulk bone loss were made. The statistical analysis was based on the Latin Square design with two blocking factors (dog and site). Tukey's post hoc test was used to adjust for multiple comparisons. Results: Histological observation revealed that while bone formed around both the xenograft and the titanium particles, bone was also noted within titanium granules. Of the five modalities of ridge preservation techniques used in this study, no one technique proved to be superior. Conclusion: The titanium granules were observed to have promising osseoconductive properties.

    The impact of the stone age diet on gingival conditions in the absence of oral hygiene.2009In: Journal of Periodontology, ISSN 0022-3492, Vol. 80, no 5, 759-768 p.Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: The objective of this study was to assess the oral microbiota and clinical data in subjects without access to traditional oral hygiene methods and who ate a diet available in the Stone Age.

    METHODS: Ten subjects living in an environment replicating the Stone Age for 4 weeks were enrolled in this study. Bleeding on probing (BOP), gingival and plaque indices, and probing depth (PD) were assessed at baseline and at 4 weeks. Microbiologic samples were collected at the mesio-buccal subgingival aspects of all teeth and from the dorsum of the tongue and were processed by checkerboard DNA-DNA hybridization methods.

    RESULTS: No subject had periodontitis. Mean BOP decreased from 34.8% to 12.6% (P <0.001). Mean gingival index scores changed from 0.38 to 0.43 (not statistically significant) and mean plaque scores increased from 0.68 to 1.47 (P <0.001). PD at sites of subgingival sampling decreased (mean difference: 0.2 mm; P <0.001). At week 4, the total bacterial count was higher (P <0.001) for 24 of 74 species, including Bacteroides ureolyticus, Eikenella corrodens, Lactobacillus acidophilus, Capnocytophaga ochracea, Escherichia coli, Fusobacterium nucleatum naviforme, Haemophilus influenzae, Helicobacter pylori, Porphyromonas endodontalis, Staphylococcus aureus (two strains), Streptococcus agalactiae, Streptococcus anginosis, and Streptococcus mitis. Bacterial counts from tongue samples were higher at baseline (P <0.001) for 20 species, including Tannerella forsythia (previously T. forsythensis), Aggregatibacter actinomycetemcomitans (previously Actinobacillus actinomycetemcomitans; serotype a), and Streptococcus spp.

    CONCLUSIONS: The experimental gingivitis protocol is not applicable if the diet (e.g., Stone Age) does not include refined sugars. Although plaque levels increased, BOP and PD decreased. Subgingival bacterial counts increased for several species not linked to periodontitis, whereas tongue bacterial samples decreased during the study period.

    Effect of a stannous fluoride dentifrice on the sulcular microbiota: a prospective cohort study in subjects with various levels of periodontal inflammation2005In: Oral Health & Preventive Dentistry, ISSN 1602-1622, Vol. 3, no 4, 263-272 p.Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: To assess the effects of an experimental 0.454% stannous fluoride (SnF2) dentifrice on the oral sulcular microbiota in patients with various stages of oral diseases using checkerboard DNA-DNA hybridization.

    MATERIAL AND METHODS: In the present one-month, single center, single product, prospective cohort trial, 37 adults (mean age 37.6) were assigned to one of four oral health condition cohorts with seven to 10 subjects each: 1. mild gingivitis, 2. marked generalized gingivitis to moderate periodontitis, 3. caries-prone and 4. treated moderate to advanced chronic periodontitis in supportive periodontal care. All four groups were asked to use the test dentifrice and a power toothbrush twice a day for one minute during a four-week test period. Before and after the trial period, Plaque Indices (PII, Silness and Löe, 1964) and Gingival Indices (GI, Löe and Silness, 1963) were recorded. Subgingival plaque samples were collected from all patients at Baseline, as well as after two and four weeks. These samples were analyzed for content of 40 bacterial species using checkerboard DNA-DNA hybridization.

    RESULTS: As a result of the only one minute brushing with the stannous fluoride dentifrice, the mean PII at Baseline was significantly lower (p < 0.05) from the mean PII at four weeks. No statistically significant differences were found between premolar and molar mean values. Moreover, no statistically significant differences were found between the mean GI at Baseline and at four weeks. The microbiological analysis showed that at baseline subjects in groups 2 and 4 had significantly higher bacterial loads of bacteria than groups 1, and 3 (i.e. A. actinomyctemcomitans P. gingivalis, T. forsythia, and T. denticola. Over the study period, the total bacterial load did not change in groups 2, 3 and 4. In groups 1 and 3, however, an increase in the loads of Streptococci spp. were noticed (p < 0.05) including S. mitis, S. intermedius, and S. sanguis (p < 0.01) suggesting an increase in the presence of early colonizing and health associated bacteria.

    CONCLUSION: One minute brushing with a 0.454% stannous fluoride dentifrice did--after four weeks--not affect the subgingival microbial profiles in patients with moderate periodontitis and treated moderate to advanced periodontitis. However, the sulcular microbial profiles of mild gingivitis and caries-prone patients were affected, indicating a shift towards a gingival health associated microbiota in the sulcular region of patients not affected by attachment loss. RUNNING HEAD: Effect of stannous fluoride on sulcular microbiota.
