Abstract

Since complete debridement of the root canals of the primary teeth is not practically possible due to the highly variable root canal anatomy, success of the endodontic therapy depends partly on the use of antibacterial irrigating agents and root canal filling materials. Recent literature indicates that anaerobes comprise a majority of the bacteria in necrotic root canals of primary teeth. The study determined the antibacterial effectiveness of four root canal filling materials namely Calcium hydroxide, Zinc oxide eugenol, Vitapex and Metapex against microbial specimens obtained directly from necrotic root canals of primary teeth. Method: Microbial specimens were collected using sterile paper points, from 15 primary maxillary and mandibular posterior teeth of randomly selected children in the age group of 4-10 years with infected non vital primary teeth, requiring pulpectomy procedure. The microbial specimens collected were subjected to microbiological analysis and the antimicrobial potential of root canal filling materials were tested using Agar diffusion technique. Results: were statistically analyzed using one-way ANOVA. Facultative/Aerobic organisms were isolated in all the cases, anaerobic organisms were isolated in 80% of the cases, and Candida albicans was isolated in 1 case. ZOE showed superior inhibitory activity against most of the organisms isolated followed by Vitapex, Calcium hydroxide and Metapex in descending order. Conclusion: Our data may be useful as a guide for relative antimicrobial effectiveness or non-effectiveness of the materials employed. In vivo studies are required to state the specific antimicrobial activity and merits and demerits of any of the test filling material.
