Abstract
AbstractIn case of failed root canal treatment endodontic retreatment of the root canal system is necessary. The aim of the present study was to compare the gutta-percha removal with Protaper retreatment files (Dentsply Maillefer, Ballaigues, Switzerland), K3 (SybronEndo) and Hero Shapers (MicroMega, Besancon, France). Method: Thirty freshly extracted human single rooted teeth were prepared with ProTaper rotary instruments up to file F3 andfilled with 30 # GP cones and AH plus sealer. The teeth were then stored for 1 week. The teeth were divide into 3 retreatment groups (n=10). The gutta-percha was removed using Protaper retreatment files, K3 and Hero Shapers. Teeth were then evaluated using radiographs. Results: Comparing the ratio between clean canals Protaper and K3 showed better debris removal as compared to Hero shaper. But no significance difference was found.
