Clinical antimicrobial efficacy of <scp>N</scp>i<scp>T</scp>i rotary instrumentation with <scp>N</scp>a<scp>OC</scp>l irrigation, final rinse with chlorhexidine and interappointment medication: a molecular study

Abstract

Supplementary steps consisting of a final rinse with CHX followed by calcium hydroxide interappointment medication promoted further decrease in the bacterial bioburden to levels significantly below those achieved by the chemomechanical procedures alone. Because the long-term outcome of root canal treatment is dependent upon maximal bacterial reduction, the present results are of clinical relevance.
