Microsurgical Management of Nonsurgical Endodontically Treated Fiasco in Natural Permanent Upper Molar Tooth – A Clinical Case Report

Abstract

Abstract The maxillary first permanent molar presents wide anatomical alterations for root number and their respective canal system. The medial root (mesiobuccal) specifically has been invariably associated to treatment failures when nonsurgical endodontic procedures have been solely carried out. In endodontic treatments, the decision to retreat the failed endodontic treatment with a surgical procedure depends on multiple factors. Evidence about the enduring prognosis of conventional retreatment (nonsurgical) comparative to invasive surgery (root end) remains questionable which requires additional scrutiny. The present case report presents a case of a patient (female, age 53 years) who presented with agony in relation to the maxillary first molar (left-sided) abutment of a four-unit fixed partial denture. Routine endodontic treatment was performed for the affected tooth which showed evidence of failure at 6-month follow-up intervals. Surgical intervention as part of the desired treatment was undertaken with the sealing of the canals done by Portland cement-based repair material. A pursual (6 months) after apicoectomy showed a complete rebuilding of the lateral apical region with freshly laid bone and a complete symptom-free patient. This clinical case report is directed to highlight the prospect of nonconservative clinical procedures once a noninvasive approach produces less anticipated results.
