Resumo
UNASSIGNED
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 Staphylococcus aureus, Escherichia coli, Enterococcus faecalis, and Pseudomonas aeruginosa, common root canal pathogens of deciduous teeth.
UNASSIGNED
An in vitro 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 post hoc comparison test. Level of significance for the tests was 5%.
UNASSIGNED
Zones of bacterial inhibition were highest for ZO + Th oil paste against the pathogenic microorganisms S.aureus, followed by E. coli, E. faecalis, P. aeruginosa while for ZO + E paste, the decreasing order against pathogenic microorganisms was E. coli, S. aureus, E. faecalis, and P. aeruginosa. Statistically significant difference was found in both the pastes, ZO + Th oil paste and ZO + E paste.
UNASSIGNED
ZO + Th oil paste showed higher levels of antimicrobial effect against the root canal pathogens.How to cite this article: Thosar NR, Chandak M, Bhat M, Basak S.
