Abstract

Objectives The aim of this work was to study the morphology of root and root canals of permanent mandibular anterior teeth in a sample of the Egyptian population.
Methods A total of 16 permanent mandibular central incisors (I1), 25 permanent mandibular lateral incisors (I2) and 15 permanent mandibular canines (C) were collected and classified into groups according to shape and number of roots. Molds of pink wax with the samples were submitted for cone beam computed tomography (CBCT). The number and shapes of roots were determined and types of root canals were assessed and classified according to Vertucci's classification. Finally, data was statistically analyzed.
Results Regarding the macroscopic appearance of I1, all the samples had one root while I2 had one root with 92%. As for C, 80% of the sample was with one root. CBCT revealed the following configurations, according to Vertucci's classification; Regarding I1, Type I was the most common canal configuration (75%) followed by type II (12.5%) and type III (12.5%) Regarding I2, Type I (60%) was the most common configuration followed by type III (28%). As for C, 66.7% of the sample was represented by type I followed by type III and IV, where each was represented by 13.3%.
Conclusions There are morphological variations in the root and root canal anatomies of the mandibular central incisors, lateral incisors, and canines of Egyptian population as compared to other populations.
