AN IN-VITRO COMPARISON OF GUTTA PERCHA REMOVAL EFFICIENCY WITH PROTAPER RETREATMENT FILES, RACE INSTRUMENT, AND RECIPROC R

2022

Background: Retreatment procedures are carried out where root canal treatment of teeth fails. There are a variety of methods used to remove gutta-percha from the root canal such as hand files, rotary files, and ultrasonic instruments. Aim: An in-vitro comparison of efficiency of gutta percha removal in retreatment using protaper retreatment files, race instruments and reciproc R. Settings and Design: The present study is an in-vitro comparative study. Methods and Material: Seventy-five extracted non carious human premolar single rooted teeth were used in this study. Root Canal Treatment of these teeth was performed and obturation carried out with Gutta Percha and AH plus sealer. The specime…
