Background: This study aimed to compare the continuous rotation and reciprocating movements of rotary files in achieving apical patency root canal retreatment. Materials Methods: vitro, experimental evaluated 64 extracted mandibular molars. The teeth were prepared up F3 with ProTaper Universal obturated using lateral compaction technique. divided into four groups (n = 16) based on mesiobuccal c...

Introduction: the major goal of endodontic treatment (ET) is complete elimination and/or maximum possible reduction bacteria and irritants in root canal system (RCS). However, persistence bacterial debris refractory to therapy may leading ET failure, being necessary realize conventional or surgical retreatment. Objective: this a case report on nonsurgical management an extensive chronic periapi...
