Comparative evaluation of post - operative pain after single visit endodontic treatment using protaper next and protaper gold rotary file systems: a randomized clinical trial

Abstract

Introduction: Postoperative pain and swelling are the unfavourable sequalae of endodontic treatment if debris produced while instrumentation gets expulsed beyond periapex. The amount of debris varies with every different instrumentation technique and design characteristics. Among the various advanced technologies and instruments available as of today are the thermal treated alloys and also the offset centre of mass. Examples of these designs are PTG & PTN respectively. In-vitro studies reported PTN expulses less debris than PTG. Nonetheless, in clinical scenario’s, the periapex tissues could act as natural barrier, the response may be affected due to hosts immunity response. Therefore, the aim of the study is to evaluate and compare post-operative pain following single visit endodontic treatment using PTN & PTG rotary file systems.
