Endodontic Management and Cone-beam Computed Tomography Evaluation of Seven Maxillary and Mandibular Molars with Single Roots and Single Canals in a Patient.

Abstract: Introduction: The knowledge of root canal morphology and the existing anatomical variations is essential for successful endodontic therapy. Methods: This report presents an extraordinary case of unusual tooth morphology involving the bilateral existence of 7 maxillary and mandibular first and second molars with a single root and a single canal in a patient. Results: Endodontic retreatment of the affected teeth #15, #19, and #18 was performed. Cone-beam computed tomography (CBCT) images confirmed our diagnostic and therapeutic measures after endodontic management of the teeth. Conclusions: This morphologic variation has not been reported in the literature. The availability of 3-dimensional images further provided the opportunity for the precise description of the anatomy of 7 maxillary and mandibular molars with single roots and single canals.
