Morphology of Roots and Canals of Maxillary First Premolars: A CBCT Study in a Peruvian Sample.

It is important to take into account variations in structures related to dental pulp for planning the most adequate endodontic treatment management. The objective of this study was to determine the morphology of roots and canals of maxillary first premolars (MFPs) using cone-beam computed tomography (CBCT). This retrospective study included a sample of 392 CBCTs of Peruvian adults proportionally selected by sex, age, and quadrant.
