In 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.

In 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.
