Morphology of maxillary and mandibular teeth analyzed by cone-beam computed tomography in a Turkish sub-population
Objectives: The aim of the present study was to evaluate the morphometric aspects of anatomy of the root canal system of maxillary and mandibular teeth
Methods: Patients referred for a CBCT radiographic examination for accurate diagnosis and treatment planning were enrolled in the study. A total of 147 patients with 1764 maxillary premolars, maxillary molars and mandibular canine teeth (each tooth group consisted of 294 tooth) were included. The number of roots and their morphology, number of canals per root, canal morphologies according to Vertuci classification, location of apical foramen, fused roots and primary variations were recorded. Assessments were done by an oral radiologist and an endodontist.
Results: The state of being three roots for maxillary first and second premolars were 3% and 1% respectively. According to vertuci classification of roots in maxillary first premolars were 66% type I in buccal canals and 62% type I in palatal canals and in second maxillary premolars were 55% type I in buccal canals and 41% type I in palatal canals. The fused roots for maxillary first and second premolars were 8% and 10% respectively. The states of being 2 canals in buccal root were 22% in maxillary first premolars and 35% in maxillary second premolars. In maxillary first premolars, 48% in buccal root, and 66% in palatal root the foramen was on the tip of the root. These values were 49 % and 88% for maxillary second premolars. In maxillary first molars, the classification of mesiobuccal, distobuccal and palatal canals were 39% type II, 78% type I and 86% type I respectively.
Conclusions: The root and canal configuration of a Turkish sub-population showed different features. CBCT scans can enhance the understanding of root canal anatomy and provide a precise description of these unusual anatomical variations with the potential of improving the outcome of endodontic treatment.
