Anti-microbial effect of probiotic versus silver nanoparticle irrigant

Disinfection of root canal system is a big challenge in the path of successful long-term treatment outcomes. 32 nonpathogenic extracted human teeth with single roots were collected for the study and were inoculated with Enterococus faecalis (E. faecalis) and later treated with silver nitrate solution and probiotic solution. The mean values of the E. faecalis count of probiotic irrigant (mean = 1.12) is lesser than that of silver nanoparticle irrigant (mean = 2.39). The probiotic irrigant had better antimicrobial efficacy than silver nanoparticle irrigant against E. faecalis.
