- 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

Journal article (peer-reviewed)abstract
- 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.

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 Twenty-two 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 or less sites the likelihood of defect fill was higher in the BDX group (LR: 3.2, 95% CI: 1.010.6, p < 0.05). Conclusions Bovine xenograft provided more radiographic bone fill than AB. The success for both surgical regenerative procedures was limited. Decreases in PD, BOP, and suppuration were observed.

Research review (peer-reviewed)abstract
- Aim:To compare histopathological characteristics of peri-implantitis and periodontitis lesions. METHODS: A search was conducted on publications up to July 2010. Studies carried out on human biopsy material and animal experiments were considered. RESULTS: While comprehensive information exists regarding histopathological characteristics of human periodontitis lesions, few studies evaluated peri-implantitis lesions in human biopsy material. Experimental peri-implantitis lesions were evaluated in 10 studies and three of the studies included comparisons to experimental periodontitis. Human biopsy material: the apical extension of the inflammatory cell infiltrate (ICT) was more pronounced in peri-implantitis than in periodontitis and was in most cases located apical of the pocket epithelium. Plasma cells and lymphocytes dominated among cells in both types of lesions, whereas neutrophil granulocytes and macrophages occurred in larger proportions in peri-implantitis. Experimental studies: placement of ligatures together with plaque formation resulted in loss of supporting tissues and large ICTs around implants and teeth. Following ligature removal, a "self-limiting" process occurred in the tissues around teeth with a connective tissue capsule that separated the ICT from bone, while in peri-implant tissues the ICT extended to the bone crest. CONCLUSION: Despite similarities regarding clinical features and aetiology of peri-implantitis and periodontitis, critical histopathological differences exist between the two lesions

Research review (peer-reviewed)abstract
- Guidelines for improving the reporting in preclinical in vivo research (ARRIVE) have been recently proposed. AIM: The aim was to assess to what extent the ARRIVE guidelines were considered in preclinical in vivo studies in implant dentistry. MATERIAL AND METHODS: Four comprehensive systematic reviews evaluated to what extent the ARRIVE guidelines were considered in preclinical in vivo studies in implant dentistry. Studies on the influence of implant material, surface and design on tissue integration to implants placed in pristine bone, in locally compromised sites and/or systemically compromised animals, as well as on peri-implant mucositis and peri-implantitis were evaluated. The four reviews introduced different modifications to the ARRIVE guidelines dedicated to the specific assignment of the review. RESULTS: A large variation in the frequency of reporting with regard to the items of the modified ARRIVE guidelines was observed. The reviews revealed that relevant information, e.g. sample size calculation, blinding of the assessor etc., was often not reported. It was also identified that several items in the ARRIVE guidelines may be less--if at all--applicable to research in implant dentistry. CONCLUSION: It is suggested that researchers implement, whenever relevant, the ARRIVE guidelines during planning and reporting of preclinical in vivo studies related to dental implants.
