Article: Evaluation of Antimicrobial Activity of Two Endodontic Sealers: Zinc Oxide with Thyme Oil and Zinc Oxide Eugenol against Root Canal Microorganisms- An Study

Aim: The present study was aimed to find out and compare the antimicrobial effect of the paste containing zinc oxide cement mixed with thyme oil (ZO + Th oil) with that of the paste containing zinc oxide and eugenol (ZO + E) against and common root canal pathogens of deciduous teeth.

Materials And Methods: An antimicrobial effect was carried out by the agar diffusion method. The ZO + Th oil paste was filled in the punched holes of Mueller Hinton agar at two equidistant points. The same was followed for ZO + E paste. For 24 hours, all the plates were incubated at a temperature of 37°C. The inhibition zones in millimeters around the wells were calculated. There were 6 times repetitions of the test for each microorganism. Data were tabulated and analyzed statistically using one-way analysis of variance (ANOVA) and Tukey's comparison test. Level of significance for the tests was 5%.

Results: Zones of bacterial inhibition were highest for ZO + Th oil paste against the pathogenic microorganisms followed by while for ZO + E paste, the decreasing order against pathogenic microorganisms was and Statistically significant difference was found in both the pastes, ZO + Th oil paste and ZO + E paste.

Conclusion: ZO + Th oil paste showed higher levels of antimicrobial effect against the root canal pathogens. Thosar NR, Chandak M, Bhat M, Basak S.
