Endodontic management of mandibular premolars with aberrant root canal morphology : Case Series

Abstract

Background: Intricate research into the internal anatomy of teeth has revealed myriad variations in root canal configurations. The mandibular premolar’s root canal system is one such tooth with complexities that usually requires special management skills in root canal treatment. Proper knowledge of the root canal anatomy, diligent radiographic interpretation and clinical inspection is essential for successful root canal treatment of the mandibular premolars. Skillful and specific root canal preparation and obturating techniques are usually needed. Methods: This paper reports two unusual cases of atypical root canal morphologies in mandibular premolars. The first case is a mandibular first premolar with Vertucci type V configuration and the second case is a mandibular second premolar with C shaped root canal both of which were successfully managed endodontically. Results: The use of CBCT (Cone beam computed tomography) and magnification has greatly helped in diagnosis and management of these cases. Conclusion: The case series describes the morphological variations found in mandibular premolars which were diagnosed and managed with the help of diagnostic aids like CBCT and dental operating microscope for the success of endodontic therapy.
