Abstract:

Introduction: Pulpal infections are caused by varied number of organisms and are located in various sites of root canal system. This micro-biota can be eliminated or reduced by using various treatment modalities. Materials & Method: Thirty two patients were selected according to the inclusion criteria and were divided into four groups viz. group A (PAD), n=10; group B (Diode laser), n=10; group C (NaOCl), n=10; group D (Normal Saline), n=2. The treatment was done according to the group and following manufacturer�??s instructions. The efficacy of each group was evaluated by using microbial culturing technique. Three samples Preoperative (1), after first application (2) and after second application of disinfection protocol (3) were taken for each group and were incubated separately for aerobic and anaerobic culture at 37ºC for 24 hrs. Microbial counting was done for each sample in the form of colony forming units (CFU) and the mean CFU counts were tabulated. Results: Microbial counting was done for both aerobic as well as anaerobic culture in the form of CFUs. The results were evaluated statistically using two-way Analysis of Variance (ANOVA) and Friedman test. All the groups showed reduction in number of bacteria. The statistical significant difference (p<0.0001) were observed for Group A, with aerobic and anaerobic microorganisms whereas for Group B and C, it was observed only with aerobic microorganisms. Conclusion: PAD, Diode laser and 5.25% NaOCl showed antibacterial action against aerobic and anaerobic bacteria.
