The purpose of the present study was to clinically and radiographically evaluate and compare the efficacy of demineralized freeze dried bone allograft (DFDBA) and bovine derived xenogenic bone graft (BDX) [Bio-Oss] with amniotic membrane (AM) as guided tissue regeneration (GTR) in the treatment of human periodontal Grade II buccal furcation defects. Ten patients suffering from chronic periodontitis, displaying bilateral Grade II buccal furcation defect, were randomly treated using DFDBA with AM (Experimental site A) or using bovine derived xenograft (BDX) with AM (Experimental site B). The clinical and radiographic parameters were recorded at baseline, 6 and 9 months. Healing was uneventful in all patients except one site which was treated with BDX + AM. At 9 months after therapy, soft tissue measurements for the DFDBA + AM group showed pocket depth (PD) reduction of 4.7 mm +/- 0.58, and relative attachment level gain of 4.8 mm + 0.32, while the BDX + AM group showed a PD reduction of 4.4 mm +/- 0.27, and AL gain of 5.1 mm +/- 0.09. Osseous measurements showed bone fill of 2.1 mm +/- 0.36 for the DFDBA + AM group and 2.43 mm +/- 0.38 for the BDX + AM group. Percentage gain in bone was 76.3% for the DFDBA + AM group and 79.6% for the BDX + AM group. Statistical analysis revealed there was no statistical difference between the two materials in all measurements. Within the limits of the present study, it can be concluded that: (1) at 9 months after surgery both therapies resulted in significant PD reductions and CAL gains and (2) significant improvement was seen in bone fill and percentage gain with both the material, however, there was no significant difference between both.

The new 0.074% diclofenac mouthwash is an effective and tolerable medicinal product for post-surgical symptomatic relief.

Background:The relatively safe nature and cost-effectiveness of herbal extracts have led to a resurgent interest in their utility as therapeutic agents. Therefore, this prospective, double-blind, randomly controlled clinical trial was designed to compare the antiplaque and antigingivitis effects of newly formulated mouthrinse containing tea tree oil (TTO), clove, and basil with those of commercially available essential oil (EO) mouthrinse.Materials and Methods:Forty patients were selected for a 21-day study period and randomly divided into two groups. The test group patients were given newly formulated herbal mouthrinse and the control group patients were given commercially available EO mouthrinse. The Plaque Index (PI), Gingival Index (GI), and Papillary Marginal Attachment (PMA) Index were recorded at baseline, 14 days, and 21 days. The microbial colony forming units (CFU) were assessed at baseline and 21 days.Results:Test group patients using herbal mouthrinse showed significant improvement in GI (0.16), PI (0.57), and PMA (0.02) scores. These improvements were comparable to those achieved with commercially available EO mouthrinse. However, the aerobic and anaerobic CFU of microbiota were reduced with the herbal mouthrinse (P = 0.0000).Conclusion:The newly formulated herbal mouthrinse and commercially available mouthrinse were beneficial clinically as antiplaque and antigingivitis agents. Newly formulated mouthrinses showed significant reduction in microbial CFU at 21 days. So, our findings support the regular use of herbal mouthrinse as an antiplaque, antigingivitis, and antimicrobial rinse for better efficacy.

Background:Neutrophils constitute the main phagocytic cell system in mammalian host defense against an infecting agent. Abnormalities in leukocyte number and function are associated with increased susceptibility to periodontal diseases. The purpose of this study is to evaluate the in vitro phagocytic properties of crevicular and peripheral blood neutrophils in healthy and periodontitis subjects.Patients and Methods:A total of 30 subjects, that is, 10 patients in each of the following three groups: healthy controls, chronic periodontitis (CP), and localized aggressive periodontitis (LAP), were included in the study. The neutrophils were isolated from the peripheral blood and gingival crevice and tested for phagocytosis of Candida albicans. The percentage of leukocytes with ingested C. albicans was determined by light microscopy.Results:A significant reduction in the phagocytic activity of crevicular fluid polymorphonuclear neutrophils (CF-PMN) of LAP subjects (mean: 54.3±7)(P<0.001) was observed, compared to healthy controls (mean: 74.2±9) and chronic periodontitis subjects (mean: 69±9)(P=0.352). The mean percentage of peripheral blood polymorphonuclear neutrophils (PMNs) with phagocytosis of opsonized C. albicans in LAP patients was significantly reduced (mean: 74.9±5)(P<0.0068) compared to the phagocytic activity of neutrophils from controls (mean:82.1±3) and chronic periodontitis subjects (mean: 82.0±5)(P=0.970). There was no significant reduction in the phagocytic activity of CF PMNs (mean: 69±9) (P=0.35) and peripheral blood PMNs (mean: 82.5)(P=0.97) in the chronic periodontitis group when compared to the control group.Conclusion:The phagocytic activity of both crevicular and peripheral neutrophils in subjects with periodontitis is altered, increasing the susceptibility to periodontitis. Thus individual susceptibility may be an additional and important modifying factor in the pathogenesis of periodontal disease.

The current study showed that curcumin has inhibitory effect on polymorphonuclear leukocyte-type MMP-9 involved in matrix degradation in periodontitis. Since Curcumin has a potent anti-inflammatory effect, it may have therapeutic potential as a host modulation agent in periodontal diseases.
