Background: The root and canal morphology of maxillary first permanent molars (MFPMs) is a very widely studied issue in endodontics. However, only one study has been conducted to date on this issue using cone-beam computed tomography (CBCT) in India, and the sample consisted of extracted teeth. Aim: To investigate the root and canal morphology of MFPMs in an Indian population, by using CBCT. Methods and Material: 487 bilateral MFPMs (974 teeth) were assessed and the root and canal morphology were determined according to Vertucci's classification. In addition, the prevalence of a second mesiobuccal canal in the mesiobuccal root (MB2) was correlated with gender, age and arch side. Results: Three roots were most commonly found in the MFPMs regardless of gender (P > 0.05), but this prevalence varied according to the side of the dental arch (P < 0.05). MB2 was present in 77.5% of 3-rooted teeth. Patients above 60 years had a higher incidence of these canals (84.7%) (P < .05). The occurrence of bilateral MB2 was 71.8% in 3-rooted MFPMs. Gender had no significant impact on the occurrence of bilateral MB2 in 3-rooted MFPMs (P > .05). The most common canal configuration was type IV (46.5%) and I (98.9%) in the mesiobuccal and distobuccal roots, respectively (P < .05). The prevalence of MB2 in 3-rooted MFPMs was higher in patients above 60 years of age. Conclusions: The root and canal morphology of MFPMs in an Indian population may have significant variations depending on the dental arch side and patient age.
