Brief Summary

The aim of thepresent study was to in- vivo evaluate the antimicrobial efficacy of commerciallyavailable ozonated olive oil with and without ultrasonic activation as rootcanal irrigant in primary endodontic infections and compare with conventionalirrigant i.e. 2.5% Sodium hypochlorite.

In the presentstudy, fifty six patients with single rooted teeth were selected. After local anaesthetic administration and rubberdam placement, access cavity was made. Working length was determined using an apexlocator and confirmed radiographically. Pretreatment sample (S1) was obtainedwith a paper point by injecting normal saline (5 ml) into the root canal andtransporting it into the peptone water. Biomechanical preparation was done upto the working length with master apical file size #40 and step back up to size#60.  The patients were randomly dividedinto four groups (n=14) - Group 1: 2.5% Sodium hypochlorite, Group 2: 2.5%Sodium hypochlorite with ultrasonic activation, Group 3 : Ozonated olive oiland Group 4: Ozonated olive oil with ultrasonic activation. Irrigation was donewith the respective irrigants during the biomechanical preparation and in Group2 and Group 4 irrigant was passively activated by ultrasonics. Postinstrumentation and irrigation sample (S2) was collected in the same manner asS1. Microbiological samples (S1, S2) were preincubated for 30 minutes andshaken vigorously in a vortex mixture for 60 seconds and then it was plated onBrain heart infusion agar and colonies were counted after 24 hours of incubationusing classic bacterial counting method.

The results ofthis study demonstrated that in intragroup comparison, statistically significantreduction was found from S1 to S2 in all the four experimental groups. Inintergroup comparison the mean reduction of bacterial counts of Group 1 (SodiumHypochlorite) and Group 3 (Ozonated olive oil) were found to be lower than thatof Group 2 (Sodium Hypochlorite with ultrasonic activation) and Group 4(Ozonated olive oil with ultrasonic activation). However, the difference wasnot statistically significant between Group 1 (Sodium Hypochlorite) and Group 3(Ozonated olive oil) but the difference was statistically significant betweenGroup 2 (Sodium Hypochlorite with ultrasonic activation) and Group 4 (Ozonatedolive oil with ultrasonic activation) with highest mean percentage bacterialreduction seen in Group 2 (Sodium Hypochlorite with ultrasonic activation).
