Evaluation of the Root and Canal Morphology of Maxillary and Mandibular Premolars in an Emirati Sub-Population.

Introduction And Aims: Numerous studies have reported that maxillary and mandibular premolars have a complex internal canal configuration, which can vary according to the race and geographic origin. Therefore, a thorough knowledge and understanding of the root and canal morphology is crucial to ensure successful outcome of root canal treatment. This retrospective study aims to describe the root and canal morphology of the maxillary and mandibular first and second premolars in the Emirati subpopulation using cone-beam computed tomography (CBCT).
