Abstract
Background: Microorganisms are the main cause of pulpal and periapical diseases. Hence, the elimination of such potential microbes is achieved by endodontic treatment. Mechanical preparation is the main mechanism to reduce the bacterial load in canals which is enhanced by intracanal irrigants. Despite these procedures, some bacteria might persist within the canals. It is important to disinfect the pulp space and dentinal tubules thoroughly with an effective endodontic irrigant to prevent reinfection of a treated root canal.
Aim: This study aimed to evaluate and compare the antimicrobial efficacy of nanosilver (NS) Solution, Azadirachta indica, sodium hypochlorite, and normal saline when used as irrigants in infected root canals of primary teeth.
Settings and design: The study was a prospective randomized control trial which was conducted as per the consort statement.
Materials and methods: Eighty pulpally involved primary teeth requiring endodontic treatment of children aged 5-12 years were selected for this study. The subjects were randomly allocated to 4 groups (3 irrigant and control groups) consisting of 20 children each where Group I = NS solution, Group II = A. indica, Group III = Sodium hypochlorite (2.5%), and Group IV = Control group. Microbiological samples were collected at the baseline (before irrigation) and postirrigation after biomechanical preparation using the selected irrigant. The samples were subjected to an anaerobic bacterial culture test. Microbial colonies were identified and expressed as colony forming units per milliliter.
Statistical analysis: Data were analyzed using one-way analysis of variance, Paired t-test, and Post hoc Bonferroni test.
Results: NS solution showed the highest mean of 4.384 × 103 ± 1.019 followed by Sodium hypochlorite with a mean of 3.500 × 103 ± 1.193 and A. indica of 2.590 × 103 ± 0.778.
Conclusion: Based on the results of this study, NS solution can be used as an alternative to other root canal irrigating solutions in primary teeth.
