Disparity in anatomy of mandibular second molar: a case report

Mandibular second molars are known to have high root canal complexity. Diagnosis and successful endodontic treatment is a challenge for multi-rooted teeth with complex root morphology. This case report represents a rare of mandibular second molar having variation in anatomy, having single root with single root canal. Proper radiographic and clinical interpretation is essential. Clinicians should be aware of disparity in root canal anatomy other than normal root canal morphology. Thus, the aim of this case report is to present an endodontic management of mandibular second molar having single root and single root canal.
