INTRODUCTION: The aim of this study was to compare the antimicrobial effects of MTAD, sodium hypochlorite (NaOCl) and their combination on endodontic micro-organisms. MATERIALS AND METHODS: Zone of Inhibition (ZI) and Minimum Inhibitory Concentration (MIC) were the techniques used. In ZI technique blood agar plates were inoculated with organisms, paper discs were soaked with irrigants and maximum zones of bacterial inhibition were recorded. In the MIC technique the irrigants were serially diluted in TSB tubes and 0.1 mL of the tested microbe solutions were added. Results were obtained on the basis of turbidity and growth on agar plates. Statistical analyses were carried out using ANOVA and Tukey tests. RESULTS: In ZI technique, we investigated 120 specimens including 5 microbial species, 3 irrigants and their control groups, each with 6 repetitions. The results demonstrated MTAD greater antimicrobial efficacy compared to NaOCl, and their mixture (M+N) against Staphylococcus (S) aureus, Enteric (E) bacteria and Enterococcus (E) faecalis (P |
