Fluorescence characteristics of E. faecalis in dentine following treatment with oxidizing endodontic irrigants

• Fluorescence readings of E. faecalis infected human dentine sections were quenched when treated with oxidizing irrigants. returned to baseline in 24 h. The fluorescence quenching effects agents need be considered using laser as a diagnostic tool assessing the quality root canal debridement or disinfection. This study aimed assess changes characteristics Enterococcus over period h following treatment endodontic Sterilised, non-functional extracted third molars embedded acrylic resin and uniformly sectioned into 2 mm thick sections. After removal smear layer, inoculated cultured for 7 days. subsequently different concentrations sodium hypochlorite (NaOCl) hydrogen peroxide (H O ). Bacterial assessed at time points calibrated device. All data normality (Kolmogorov Smirnoff test) analysed ANOVA Bonferroni post-hoc tests. irrigants vitro .
