This study aims to investigate the root canal anatomy of human extracted permanent maxillary anterior teeth in patients reporting to our dental institution in Chennai using cone beam computed tomography (CBCT).

Materials and Methods:

A total of 285 maxillary anterior teeth comprising of 100 central incisors, 85 lateral incisors, and 100 canines extracted from various patients reporting to our institution were studied. The number of roots and number of canals were assessed; following which, the root canal anatomy of each tooth was evaluated for the canal pattern using CBCT. The collected data were analyzed using IBM. SPSS statistics software 23.0 version.


All the teeth examined were observed to be single rooted. All maxillary central incisors displayed Type I (100%) pattern whereas maxillary laterals and canines displayed canal variations. In maxillary laterals, Type I pattern (98%) was most prevalent followed by Type II (2%) configuration. Maxillary canines revealed a predominant Type I (96%) canal pattern followed by Type II (3%) and Type III (1%).


A varied root canal anatomy was observed in maxillary anterior teeth among Chennai urban population in this institutional-based study. The most frequent canal pattern reported in the maxillary anterior dentition was Type I. Type II was observed in both maxillary lateral incisors and maxillary canines whereas Type III canal configuration was reported only in maxillary canines.
