Abstract :

Aim: To determine the root canal irrigation technique that is most efficient at reduction of Enterococcus faecalis in persistent periradicular disease. Materials and Methods: 60 healthy adult patients presenting with symptomatic and radiographic evidence of chronic apical periodontitis were selected as study subjects and divided into 3 equal groups based on irrigation technique used. During and after canal preparation Group (Gp) 1 samples were irrigated with 3% NaOCl and 17 % EDTA using Max–i–probe side vented needle, which was used as control, Gp 2 & 3 samples were supplemented with ultrasonic & Diode laser activation of irrigants used in Gp 1, respectively. Pre and post intervention samples were collected using sterile paper points and transported in thioglycolate medium to the microbiological lab for incubation. The colony–forming units (CFUs) grown were counted by using Open CFU software. The value obtained was then transformed into actual counts based on the known dilution factors. Results: The percentage decrease in the E. faecalis was around 98.46%, 92.91% and 76.79% in Gp 3, Gp 2 and Gp 1 samples. The decrease in pre & post test microbial count was statistically significant under all three groups Conclusion: Laser activation of 3% NaOCl and 17% EDTA is better than ultrasonic activation and conventional syringe irrigation of root canals in vivo. Laser disinfection is a viable option for incorporation in routine clinical practice to reduce E. faecalis in root canals prior to intracanal medication/obturation.
