چکیده    Background. elimination of bacteria from the root canal system is one of the aims of endodontic treatment; hence the incorporation of antibiotics into sealers can increase their antimicrobial efficacy. the aim of the present study was to determine the in vitro antimicrobial effects of ah26 and ah plus sealers mixed with amoxicillin, triple antibiotic paste and nanosilver on enterococcus faecalis. methods. in this experiment, amoxicillin, triple antibiotic paste and nanosilver powder were added at 10% of the total sealer weight to ah26 and ah plus sealers and then cultured freshly or after 1, 3, and 7 days with suspension of e. faecalis for 24 hours. the zones of growth inhibition for e. faecalis were evaluated in each group. results. incorporation of nanosilver did not increase antibacterial effects of the sealers. sealers combined with amoxicillin exhibited the highest antibacterial efficacy in fresh condition. in the set specimens, the results demonstrated that the mixture of sealers and triple antibiotic pastes exhibited the greatest antibacterial efficacy. conclusion. amoxicillin and triple antibiotic paste significantly improved the antibacterial properties of ah plus and ah26 sealers. such properties decreased with time, but the use of sealeramoxicillin/triple paste combination was still superior to using sealers alone or in combination with nanosilver.
