Comparative evaluation of the antibacterial activity of two Biocompatible materials i.e. Biodentine and MTA when used as a direct pulp capping agent against streptococcus mutans and Enterococcus faecalis- An in vitro study

Abstract

Aim: This study aims to evaluate and compare the antibacterial potential of biodentine and mineral trioxide aggregate (MTA) cement against Streptococcus mutans and Enterococcus faecalis. Materials and Methods: Biodentine and MTA were used to assess the antibacterial efficacy against S. mutans and E. faecalis., using the agar well diffusion test. Agar plates were incubated at 37°C for 24 h in an incubator. The diameter of bacterial inhibition zones around each well was measured to the nearest size in mm with a digital caliper. Results: Inhibition zones formed by Biodentine against S. mutans and E. faecalis were significantly larger than the zones formed by MTA (P < 0.05). Conclusion: From the present study, it can be concluded that Biodentine and MTA have antimicrobial activity against S. mutans and E. faecalis, but higher mean zone of inhibition was recorded in biodentine.
