ABSTRACT
Aim and objective:
To evaluate and compare the cytotoxicity and antimicrobial activity of various inorganic metal oxide nanoparticles along with vehicles when used as intracanal medicaments in the root canal system. Materials andmethods:
The study included triplicates (n = 36 times) that were subjected to n calcium oxide (CaO), n zinc oxide (ZnO), n magnesium oxide (MgO), and metapaste as intracanal medicaments. The efficacy of novel intracanal medicaments was evaluated for biocompatibility assay using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) reagent following antimicrobial efficacy against Enterococcus faecalis (E. faecalis) was evaluated using zone of inhibition (ZOI) and minimum inhibitory concentration (MIC). The statistical analysis Kruskal-Wallis test, student t-test, and analysis of variance (ANOVA) using Statistical Package for the Social Sciences (SPSS) software (v.20.0).Results:
The order of proliferative activity of experimental groups on L929 mouse fibroblast cells using MTT assay was metapaste > nCaO > nMgO > nZnO). After evaluation of antimicrobial efficacy, group I nCaO showed maximum ZOI and MIC against E. faecalis, which showed high statistically significant differences between all four groups after ANOVA (p < 0.0001*).Conclusion:
n calcium oxide (CaO) mixed with propylene glycol (PPG) 400 has a potential role as an intracanal medicament with minimum cytotoxic effect and maximum antimicrobial activity against endodontic pathogens. Clinicalsignificance:
Nanoparticles-based intracanal medicament can provide a promising future in reducing endodontic flareups when used as intracanal medicament.
