Uncommon Root Canal Morphology in a Mandibular Second Premolar: Diagnostic and Clinical Insights

Abstract

Excellent success rate of endodontic treatment is achieved by thorough knowledge of anatomical and morphological variations of the root canal system. Endodontist must be able to recognize teeth that differ from standard morphology, because these variations can complicate the treatment process. Ensuring thorough cleaning and sealing of these teeth is crucial, because it leads to the negative outcomes. Mandibular premolars, are known to have unique and irregular anatomical characteristics. Presence of separate three canals with distinct apical foramina of mandibular premolars is a rare occurrence. While mandibular first premolars may exhibit three canals up to 23% cases, this is much less common in second premolars, with an incidence of 0.4%. Furthermore, mandibular second premolar with three roots is found in just 0.2% cases. Following case report discusses the endodontic management of a mandibular second premolar which has unique variations in canal anatomy.
