Retreatment of a Mandibular Molar with Chronic Apical Abscess and Internal Root Resorption with the GentleWave® Procedure: A 16-Month Clinical Case Report

Abstract

Introduction: Internal root resorption is a progressive loss of dentin in teeth with inflamed and possibly partially necrotic pulp tissue. If diagnosed at early stages, the process is halted by endodontic treatment. While endodontic treatment is the preferred treatment modality for internal root resorption, current standard endodontic techniques pose a challenge for cleaning, disinfection and obturation of these irregular and inaccessible areas, especially within the apical third.
