Maxillary Permanent First Premolars With Three Canals: Incidence Analysis Using Cone Beam Computerized Tomographic Techniques.

Aim: This study aimed to analyze incidence of three canals in human permanent maxillary first premolar teeth using cone beam tomographic techniques.

Materials And Methods: The samples were divided into three groups namely Group (GP) I (single rooted [ = 255]), GP II (two rooted [ = 326]), and GP III (three rooted [ = 8)]. The teeth were processed, mounted in arches, coded, and subjected to cone beam tomographic scanning.
