Abstract
This study aimed to compare the efficacy of Photo-Activated Disinfection (PAD), 2.5% NaOCl and 2%
CHX in E.faecalis eradication. Forty-two single rooted human teeth were contaminated with E. faecalis. The roots
were divided into one positive control group (n=10) in which the roots were irrigated with normal saline and three
experimental groups (n=10); groups 1, PAD; groups 2, 2.5% NaOCl; groups 3, 2% CHX. Microbiological samples
were collected with sterile paper points, and bacterial growth was determined. Surface topography was
investigated under a scanning electron microscopy (SEM). Treatment of root canals with PAD or irrigating with
normal saline did not significantly reduce the number of E.faecalis 2.5% NaOCl, 2% CHX significantly reduced
the number of E.faecalis (66.7% and 86.8%, respectively) when compared with the control group(p<0.05).
Keywords : Photo-Activated disinfection, antimicrobial Efficacy, root canal
