Abstract

An in vitro study using polyethylene tubes filled with Grossman's sealer, Rickert's sealer, and N2 permanent was conducted over a six month period in an effort to determine their lasting antimicrobial properties against eight different microorganisms.

From the study it was observed that N2 permanent possesses a long-lasting antimicrobial effect, but this effect appears to diminish greatly with time. Further investigation is needed to determine whether or not the effect is actually permanent in nature. The N2 permanent was also shown to have broader antimicrobial effectiveness against the eight microorganisms tested. N2 permanent produced zones of inhibition against five of the eight organisms, Grossman's sealer produced zones against three, and Rickert's sealer produced zones of inhibition against only one organism. The antimicrobial effect of both Grossman's and Rickert's sealers was observed to be non-existent at 24 hours.
