Locally delivered SMV provides a comfortable and flexible method to improve clinical parameters and also to enhance bone formation.

The use of autologous PRF or PRP were both effective in the treatment of furcation defects with uneventful healing of sites.

Background: Obesity is considered as a strong risk factor of inflammatory periodontal tissue destruction. The purpose of this study is to determine presence of progranulin (PGRN) and high sensitivity C reactive protein (hs CRP) levels in serum and gingival crevicular fluid (GCF) in obese subjects with chronic periodontitis and to find an association, if any.Material and methods: 40 subjects (20 males and 20 females) were selected based on their clinical parameters into four groups (10 subjects in each group): group 1 (healthy non obese), group 2 (healthy obese), group 3 (non obese with chronic periodontitis) and group 4 (obese with chronic periodontitis). Serum and GCF PGRN levels were estimated by enzyme linked immunosorbant assay (ELISA) and hs CRP levels were estimated by immunoturbidimetry method.Results: The mean PGRN and hs CRP concentration both in serum and GCF were highest for group 4 followed by group 3, group 2 and least in Group 1.Conclusion: PGRN and hs CRP may be novel biomarkers of the chronic inflammatory response in obesity and chronic periodontitis.

Background: Along with conventional periodontal surgical therapy, local delivery of antibiotics may provide more effective treatment in smokers by targeting tissue-invasive bacteria. The aim of this randomized, placebo-controlled, doublemasked clinical trial was to evaluate the adjunctive effects of subgingivally delivered 0.5% azithromycin (AZM) as an adjunct to scaling and root planing (SRP) in the treatment of chronic periodontitis in smokers. Methods: Fifty-four patients were randomized and categorized into two treatment groups: Group 1 -26 subjects who received (SRP) plus placebo gel and Group 2 -28 subjects who received (SRP) plus 0.5% azithromycin. Clinical parameters were recorded at baseline, 3, 6 and 9 months. They included Plaque Index (PI), modified Sulcus Bleeding Index (mSBI), probing depth (PD) and clinical attachment level (CAL). Results: Azithromycin resulted in significant improvements. A single application of AZM resulted in attachment gain at 9 months of 2.44 ± 0.64 mm as compared to 0.18 ± 0.68 mm for the placebo. Similarly, pocket depth and PI were significantly reduced but no change in the mSBI was noted. Conclusions: When compared to the placebo, the adjunctive use of 0.5% AZM resulted in significant improvement in clinical outcome in the treatment of chronic periodontitis among smokers.

Within the limits of the present study, there is greater bone fill at sites treated with PRF with conventional OFD than conventional OFD alone.
