Abstract
INTRODUCTION: It is widely accepted that the permanent maxillary central incisor almost invariably has a single canal. METHODS AND RESULTS: This case reports a maxillary central incisor canal morphology that differs from this predominant form, a single-rooted permanent maxillary central incisor with 1 main canal that separated into 2 distinct canals in the apical third with 2 apical foramina. The presence of a superimposed mesioden was also established. Nonsurgical endodontic retreatment achieved an optimal result. CONCLUSIONS: There is greater variation in root canal morphology of permanent maxillary central incisors than population studies would suggest.
