- Background: Several studies have found correlations between diabetes and an increased prevalence of periodontitis. Objective: To analyse, in a group of subjects with type 2 diabetes (T2D), (i) the association between medical characteristics and severe periodontal disease and (ii) dental care habits and knowledge of oral health. Methods: One hundred and ninety-one subjects with T2D were examined. Based on assessment of marginal bone height in panoramic radiographs, two periodontal subgroups were identified: one periodontally diseased (PD+) and one periodontally healthy (PD-) group. All subjects completed a questionnaire about their medical and oral health. Results: Twenty per cent of the subjects were classified as PD+. This was verified by clinical parameters. PD+ individuals had higher haemoglobin A1c (HbA1c) levels (p=0.033) and higher prevalences of cardiovascular complications (p=0.012). They were also less likely to be of Scandinavian origin (p=0.028) and more likely to smoke (p < 0.001) than the PD- group. The PD+ group rated their oral health as poor (p < 0.0001) and believed that T2D had an influence on their oral status (p < 0.0001). Conclusion: The best predictor for severe periodontal disease in subjects with T2D is smoking followed by HbA1c levels. T2D subjects should be informed about the increased risk for periodontal disease when suffering from T2D.

- AbstractAim: The aim of the present study was to examine how deleterious current smokingand the use of Swedish moist snuff (snus) is for periodontal health compared with nontobaccousers.Materials and Methods: The studies comprised three epidemiological crosssectionalstudies, in 1983, 1993 and 2003, of stratified random samples aged 20, 30, 40,50, 60 and 70 years. The numbers of dentate participants were 550, 552 and 523,respectively. The participants were examined clinically and radiographically.Diagnostic criteria were the number of teeth, plaque, gingival status, probing pocketdepth (PPD)X4 mm, height of the alveolar bone level and classification by periodontaldisease experience. In addition, participants were asked about their tobacco habits.Results: Multiple logistic regression shows, after adjusting for age, gender andsociodemographic variables, that relative to non-tobacco users, cigarette smokers hadstatistically significant less gingivitis, a higher frequency of PPDX4mm and a higherincidence of severe periodontitis. There was no significant association betweengingivitis, frequency of PPDX4mm and periodontal disease experience and snus use.Conclusions: Cigarette smokers were found to have a statistically significant higherrisk of severe periodontitis than non-tobacco users and users of snus. Using snus didnot seem to be a risk factor for periodontitis

- Objectives: The aim was to study a regenerative surgical treatment modality for peri-implantitis employing submerged healing. Material and Methods: Twelve patients, having a minimum of one osseointegrated implant with peri-implantitis, with a progressive loss of >= 3 threads (1.8 mm) following the first year of healing were involved in the study. After surgical exposure of the defect, granulomatous tissue was removed and the implant surface was treated using 3% hydrogen peroxide. The bone defects were filled with a bone substitute (Algipore((R))), a resorbable membrane (Osseoquest((R))) was placed over the grafted defect and a cover screw was connected to the fixture. The implant was then covered by flaps and submerged healing was allowed for 6 months. After 6 months the abutment was re-connected to the supra-structure. Results: A 1-year follow-up demonstrated clinical and radiographic improvements. Probing depth was reduced by 4.2 mm and a mean defect fill of 2.3 mm was obtained. Conclusion: Treatment of peri-implant defects using a bone graft substitute combined with a resorbable membrane and submerged healing results in defect fill and clinical healthier situations.

- AIM: To look for clinical signs of periodontal disease in young adults who exhibited radiographic bone loss and detectable numbers of Aggregatibacter actinomycetemcomitans in their primary dentition. MATERIAL AND METHODS: Periodontal status and radiographic bone loss were examined in each of the subjects 16 years after the baseline observations. Techniques for anaerobic and selective culture, and checkerboard, were used to detect periodontitis-associated bacterial species. The isolated A. actinomycetemcomitans strains were characterized by polymerase chain reaction. RESULTS: Signs of localized attachment loss were found in three out of the 13 examined subjects. A. actinomycetemcomitans was recovered from six of these subjects and two of these samples were from sites with deepened probing depths and attachment loss. Among the isolated A. actinomycetemcomitans strains, serotypes a-c and e, but not d or f, were found. None of the isolated strains belonged to the highly leucotoxic JP2 clone, and one strain lacked genes for the cytolethal distending toxin. CONCLUSIONS: This study indicates that the presence of A. actinomycetemcomitans and early bone loss in the primary dentition does not necessarily predispose the individual to periodontal attachment loss in the permanent dentition.

- 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.

- BACKGROUND: The chewing stick, the miswak, is used in many developing countries as the traditional means for oral hygiene. It is prepared from the roots, twigs and stem of Salvadora persica or other alternative local plants. OBJECTIVES: To compare the effects of the chewing stick miswak (from S. persica) and toothbrush on subgingival plaque microflora among Saudi Arabian individuals. Further, to investigate whether components extracted from S. persica may interfere with the subgingival plaque micro-organisms. MATERIAL AND METHODS: Fifteen healthy Saudi Arabian male volunteers aged 21-36 years were included in a single-blind, randomized cross-over study. The participants were taught how to use each device properly. Plaque sampling for DNA test was performed at the baseline, 1 week after professional tooth cleaning, and after 3 weeks of either miswak or toothbrush use. Identification and quantification of microbial species were performed by the checkerboard method, using whole genomic, digoxigenin-labelled DNA probes. Inhibition zones around miswak were examined on agar plates with Actinobacillus actinomycetemcomitans and the leukotoxicity of this bacterium was analyzed in a bioassay with macrophages+/-extracts of miswak. RESULTS: Miswak and toothbrushing had a similar influence on the levels of the subgingival microbiota. However, A. actinomycetemcomitans was significantly more reduced by miswak (p<0.05) than by toothbrushing. These results were supported by our in vitro results which, indicated that extracts from S. persica might interfere with the growth and leukotoxicity of A. actinomycetemcomitans. CONCLUSIONS: In contrast to toothbrush use, miswak use significantly reduced the amount of A. actinomycetemcomitans in the subgingival plaque.
