Background. In India there have been limited number of studies on periodontal status among drug addicts, and thus this study aims to assess the Oral hygiene and periodontal status in substance abusers and compare it with non-substance abusers. Methods. A comparative study was conducted to assess the periodontal status in substance abusers. Non-substance abusers were procured from the general population of Bangalore. From the control group 250 non-substance abusers were age and sex matched with the study population of substance abusers. The oral hygiene and periodontal condition of all subjects was assessed using Oral hygiene index- simplified (OHI-S), Russell's periodontal indices and Gingival bleeding index. Results. The mean of OHI-S and Periodontal Index (Russell's Index) scores were higher (2.70 and 3.68, resp.) in substance abusers than the control group (2.45 and 2.59, resp.). The mean Gingival bleeding score was lower (9.69) in substance abusers than the control group (22.7) and found to be statistically significant. A positive correlation found between OHI-S and Russell's periodontal index whereas negative correlation was found between OHI-S and Gingival bleeding in substance abusers. Conclusions. Though the oral hygiene was fair, more periodontal destruction and less of gingival bleeding were observed in substance abusers as compared to control group.
Objective:Our objective was to determine the efficacy of pre-procedural rinsing with chlorhexidine in reducing bacterial aerosol contamination during use of ultrasonic scaler and comparing the efficacy of water, non-tempered chlorhexidine and tempered chlorhexidine in reducing bacterial count in aerosols when used as a pre-procedural rinse.Materials and Methods:The study was designed to include 30 systemically healthy patients in different age groups. The patients were divided randomly into 3 groups (I, II, III) of 10 patients each to be administered with sterile water, non tempered chlorhexidine and tempered chlorhexidine, respectively, as a pre-procedural rinse. The aerosol produced by the ultrasonic unit was collected at 3° clock, 6° clock and 12° clock positions on blood agar plates within a range of 4 feet in all the three groups. The blood agar plates were incubated for 48 hours and the total number of colony forming units (CFUs) were counted and statistically analyzed.Results:The results showed that CFU in group III and group II were significantly reduced when compared to group I with F=1084.92, P<0.001 (ANOVA). Also, CFU in group III was significantly reduced when compared to group II with P<0.001.Conclusions:Pre-procedural rinse can significantly reduce the viable microbial content of dental aerosols and tempered chlorhexidine was more effective than non-tempered chlorhexidine.
Background:Periodontitis is bacteria-related chronic inflammatory condition characterized by pocket formation, loss of clinical attachment, gingival recession, mobility, and eventual loss of teeth. The purpose of this study was to clinically evaluate the need for elimination of the pocket epithelium during mucoperiosteal flap surgery aimed at reattachment or re-adaptation.Materials and Methods:A split mouth design was done to compare modified Widman flap (MWF) with removal of the pocket epithelium and crevicular mucoperiosteal flap (CMF) without removing the pocket epithelium. The following measurements were taken after 1 month of completion of nonsurgical phase gingival index (Loe and Silness), plaque index (Silness and Loe), mobility, furcation involvement, level of attachment, pocket depth, gingival recession, gingival contour index, and dentinal hypersensitivity (ice stick test). In addition to these measurements, which were taken immediately prior to the surgery (baseline), 1- and 3-month and 6 months postsurgical measurements were also recorded.Results:The results of this study showed a greater reduction of mean probing depth in the test group (MWF). The control group (CMF) showed greater mean gingival recession compared to the test group throughout the study period. The test group showed more gain in the clinical attachment levels compared with the control group. The difference between the two groups was statistically significant (P < 0.001).Conclusions:The results of this study demonstrate that MWF surgery was more effective in reducing mean probing depth, showed greater gain in clinical attachment, and demonstrated less gingival recession.
