Disinfection of artificially contaminated Resilon cones with chlorhexidine and sodium hypochlorite at different time exposures.

Objective: The aim of this study was to evaluate the efficiency of chlorhexidine (CHX) and sodium hypochlorite (NaOCl) solutions on Resilon cones that were artificially contaminated with microbial samples of Enterococcus faecalis or Candida albicans at various concentrations and time exposures.

Study Design: Resilon cones artificially contaminated with E faecalis or C albicans were left in contact with 1% NaOCl, 5% NaOCl, and 2% CHX disinfecting solutions for 1 and 5 minutes. The cones were then individually transferred to the test tubes, which contained 10 mL of thioglycollate media, and were incubated at 37 degrees C for 7 days.

Effects of sodium hypochlorite and chlorhexidine solutions on Resilon (synthetic polymer based root canal filling material) cones: an atomic force microscopy study.

The aim of the present study is to evaluate the effects of 2% chlorhexidine and 5.25% sodium hypochlorite on the surface properties of Resilon cones with the atomic force microscopy. The Resilon cones were immersed in disinfecting agents (5.

Postoperative pain after endodontic retreatment: single- versus two-visit treatment.

Objective: The purpose of this clinical study was to determine the effect of 1- or 2-visit root canal treatment on the postoperative pain in the retreatment cases.

Study Design: Two hundred eighteen cases that required retreatment were included in the study. Obturated and unfilled canal space and the status of periapical tissues were evaluated according to the PAI index.
