| ABSTRACTBackground: The antimicrobial agents are added to root canal sealers to improve their antibacterial effect. Thepurpose of this study was to evaluate three root canal sealers (DORIFILL, ENDOFILL, APEXIT PLUS) for their antimicrobialeffect by using the agar diffusion test (ADT).Materials and Methods: The antimicrobial effect of three root canal sealers was tested by the agar diffusion test.Fifteen petriplates . Five cavities , each one measuring 5ml in diameter and 4ml in depth ,were made in each agarplates using cork poorer and then completely filled with the products to be tested. All plates were incubated for 72hours at 37°C under aerobic conditions, and zones of inhibition were measured .Statistical analysis was conductedusing a one-way analysis of variance (ANOVA), P value equal or greater than 0.05 was considered as a statisticallynon significant, P value equal or greater than 0.01 and less than 0.05 was considered as statistically significant, wereas P less than 0.01 was considered as statistically highly significant.Results: All of the sealers caused bacterial growth inhibition. Their effectiveness, in descending order of antimicrobialactivity, was as follows: ENDOFILL DEXAMETHASONE, DORIFILL, APEXIT PLUS.The sustaining period of the antimicrobial action of all types of sealers used in this study was 24 hrs only. Noantimicrobial activity was seen after 72 hrs.Conclusions: Root canal sealers showed different inhibitory effects depending on their types and the bacterial strainstested. Root canal sealers containing Dexamethasone and eugenol proved to be effective against themicroorganisms studied.Keywords: Antimicrobial activity, endodontic treatment, roots canal sealers.
