Antimicrobial Efficacy of Obturating Materials used In Deciduous Teeth-An in vitro study

dental

ABSTRACT Preservation of deciduous tooth with non-vital pulp has been a major problem for pediatric dentistry. In such cases, the preferred treatment modality is pulpectomy. The objective of pulpectomy is complete removal of necrotic and irreversibly infected pulp of an affected tooth but in spite of chemomechanical preparation and copious irrigation of canal, there are chances of failure of pulp therapy due to entrapped microorganism in the canal space owing to the tortous and complex nature of the root canal system and change in their morphology with resorption. AIM: The aim of the study was to assess the antimicrobial efficacy of different obturating materials used in deciduous teeth. MATERIAL AND METHOD: In the present study, antimicrobial efficacy of Metapex, Zinc Oxide Eugenol (ZOE), Calcium hydroxide with chlorhexidine, and Endoflas were assessed and compared with each other. RESULTS: Intergroup comparison at 24 hours (Tukey’s test) revealed significant difference amongst all the groups. Endoflas had higher zone of inhibition as compared to all the other groups except group treated with Zinc Oxide Eugenol. CONCLUSION: The antimicrobial activity of obturating materials according to results obtained from the present study can be summarized as follows: Endoflas > ZOE > Calcium hydroxide with chlorhexidine > Metapex
