    Background and aims. A combination of guided tissue regeneration (GTR), bovine porous bone mineral (BPBM), and platelet rich plasma has been already applied for the regeneration of intrabony defects. The aim of this study was to determine the role of plasma rich in growth factor (PRGF) alone in the periodontal regeneration of intrabony defects in humans as compared with BPBM/GTR Technique.Materials and methods. In this split-mouth clinical trial, nine advanced periodontal patients with 20 intrabony defects were randomly treated with a combination of either BPBM/GTR (control) or PRGF (test). Periodontal parameters including gingival recession, probing depth (PD), gingival index (GI), plaque index (PI), and relative clinical attachment level (CAL) were evaluated at baseline and 6 months post-operatively.Results. No difference was observed at baseline between the two groups. At 6-month post-treatment, both techniques demonstrated significant reduction in CAL, PD and GI. The mean pocket depth reduction in control group was 4.1 ± 1.52 mm and 4.5 ± 1.5 mm on buccal and lingual sites, respectively (P < 0.0001); and 3.6 ± 0.9 mm in the test group. The changes in CAL in the deepest part of the defect were 3.06 ± 1.79 mm and 2.33 ± 0.78 mm for test and control groups, respectively. No statistically significant difference was detected between the two groups after 6 months.Conclusion. According to the results, the use of PRGF alone, similar to BPBM/GTR improves clinical parameters and plays a significant role in PD reduction and CAL gain.

    Background and aims. Statins, the mevalonate pathway inhibitors, have effects on bone formation in vitro and in vivo. The aim of the present study was to investigate whether injection of statins could lead to ectopic bone formation in rats.Materials and methods. A single dose (0.5 mg) of simvastatin, atrovastatin, lovastatin and polyethylene glycol (control material) were injected into four quadrants of dorsal subcutaneous tissue in twelve rats. Intramuscular injections of the same statins were also done in femur and arm muscles of eight other rats.Results. Cartilage formation was observed in simvastatin-treated area in one rat after six weeks. Bone formation was also evident in lovastatin-treated area in one rat and simvastatin-treated area in another after this period. No hard tissue formation was detected in muscles.Conclusion. Subcutaneous injection of simvastatin and lovastatin can induce ectopic bone formation.

    Background and aims. A high number of patients with periodontitis may have undiagnosed diabetes. It is possible that gingival crevicular blood from routine periodontal probing may be a source of blood for glucose measurements. The aim of this study was to compare gingival crevicular blood and fingerstick blood glucose measurements using a self-monitoring de-vice with the standard laboratory plasma glucose measurement.Materials and methods. 30 patients with periodontitis and positive bleeding on probing were chosen. Blood samples of two sites were analyzed using a glucose self-monitoring device. In 50 diabetic and 50 non-diabetic patients, after testing fast-ing plasma glucose (FPG), glucose levels in gingival crevicular blood (GCBG), and capillary fingerstick blood (CFBG) sam-ples were analyzed using the same device.Results. In non-diabetics, the analysis of agreement failed to prove sufficient agreement between the paired methods (FPG & CFBG, FPG & GCBG, and CFBG & GCBG). In diabetics, this analysis revealed sufficient agreement only between FPG & CFBG, and between FPG & GCBG measurements.Conclusion. Gingival crevicular blood can be used for testing blood glucose during periodontal examination in diabetic periodontal patients but not in non-diabetic individuals.

    Background and aim. The use of certain lasers has been proposed as an adjunctive method in periodontal pocket therapies. The objective of this study was to investigate the effects of Nd:YAG laser on the clinical periodontal parameters following scaling and root planning (SRP) in comparison to SPR alone.Materials and methods. Six adults with moderate to severe chronic periodontitis, each with at least two 4- to 7-mm pockets in single-rooted teeth, were selected. From a total of 68 sites studied, 28 were randomly allocated to the control group receiving SRP alone and 40 pockets were allocated to the test group receiving SRP assisted by Nd:YAG laser therapy (100 mJ/Pulse, 2 Hz, 2 min). Clinical parameters were recorded and compared before and three months after treatment. The data was analyzed using SPSS software.Results. Both test and control groups revealed significant improvements in pocket probing depth, 3.2 ± 1.4 mm and 1.4 ± 1 mm respectively, P < 0.001), clinical attachment level (2.2 ± 1.6 mm and 0.6 ± 1.2mm respectively, P < 0.001), and bleeding on probing (77.5% and 46.4% respectively, P < 0.05). However, the improvement in the test group was significantly higher than in the control group (P < 0.01).Conclusion. Nd:YAG laser can be suggested as an adjunctive method for treatment of periodontal pockets.

    Background and aims. A link between the occurrence of severe periodontitis and several systematic health changes including an altered lipid metabolism has been suggested. The aim of this study was to investigate the relationship between chronic periodontitis and serum lipid levels.Materials and methods. Thirty patients with chronic periodontitis (the community periodontal index of treatment needs – CPITN scores III & IV; age range 30-40 years old) as test group and 30 healthy individuals as control group were selected. The levels of serum lipids including total cholesterol and triglyceride as well as high- and low-density lipoproteins (HDL and LDL) were assessed. The relationship between serum lipids and periodontal disease was tested using Student’s t-test.Results. There were no significant differences in any criteria between case and control groups. The presence of periodontal disease was significantly related with higher total cholesterol in the case group (p < 0.05). Triglycerides, HDL, and LDL did not show any difference between case and control groups.Conclusion. Chronic periodontitis raises the chance of occurrence of hyperlipidemia in healthy people. The findings of this study support the reports linking increased prevalence of changing serum lipids among patients with periodontal disease

    Background and aim. The toothbrush is the most widely used tooth-hygiene tool, and numerous designs have been manufactured, claiming superior plaque removal. This study aimed at comparing the efficacy of a tooth wipe to a manual toothbrush on reduction of microbial plaque.Materials and methods. This crossover study was conducted on 30 subjects at two visits with one-week interval. Before each visit, individuals refrained from brushing teeth for 12 hours, had their regular meal, and then avoided to eat hard and/or soft foodstuff. Subjects were asked to brush their teeth with the allocated toothbrush (without toothpaste) using the Bass technique for 2 minutes at first visit and with the alternate toothbrush at the second visit. Pre- and post-brushing plaque was measured for total, proximal and buccolingual surfaces using the O’Leary Plaque Index. Paired t-test was used to analyze data.Results. The overall plaque indices were significantly reduced with the tooth wipe and the manual brush (P = 0.000). There were no significant differences between tooth wipe and manual brush for removing plaque at total surfaces (46.01 ± 17.2% vs. 47.73 ± 17.04%, P = 0.75) and proximal surfaces (28.76 ± 23.15% vs. 43.71 ± 23.77%, P = 0.06). However, the plaque reduction at buccolingual surfaces by tooth wipe was significantly higher than that by manual brush (79.37 ± 23.54% vs. 56.83 ± 22.33%, P = 0.001).Conclusion. The results indicate the tooth wipe is as effective as the manual toothbrush and can be used for marinating oral hygiene.

    Background and aim. The aim of the present study was to evaluate the frequency, extension and severity of the gingival recession in a Greek adult population sample.Materials and methods. The study was performed on 800 patients, 336 males and 446 females between 18-77 years old, which sought dental treatment in a private dental practice. All measurements of recession depth and width were done with a periodontal probe and under sufficient illumination. The type of gingival recessions was evaluated based on Miller’s classification. Statistical analysis was accomplished using chi-square test.Results. The overall plaque indices were significantly reduced from 39.37 ± 20.76 to 20.62 ± 13.42 using the tooth wipe, and from 35.82 ± 16.82 to 19.70 ± 11.15 using the manual brush (P = 0.000). There were no significant differences between tooth wipe and manual brush for removing plaque at total surfaces (46.01 ± 17.2% vs. 47.73 ± 17.04%, P = 0.75) and proximal surfaces (28.76 ± 23.15% vs. 43.71 ± 23.77%, P = 0.06). However, the plaque reduction at buccolingual surfaces by tooth wipe was significantly higher than that by manual brush (79.37 ± 23.54% vs. 56.83 ± 22.33%, P = 0.001).Conclusion. Considering the high prevalence of this clinical study, implementation of oral hygiene instructions and conducting analytical and experimental researches would be a necessity
