Abstract

Background: Thorough knowledge of root morphology which varies in different population is very important for successful endodontic management. The objective of the present retrospective study is to observe the root morphology of permanent mature maxillary canine in Eastern Indian subpopulation. Materials and Methods: In this study, 212 permanent maxillary canines of both male and female patients (14–50 years age group) collected from a tertiary health care Centre in Kolkata, West Bengal were processed through iRYS NNT viewer software and evaluated for the root morphology, canal configuration with its variation, effect of gender on these variables. Results: The statistical analysis revealed that 99.1% of maxillary canines have a single root with a single canal. Root diameter and dentine thickness were higher in males than females. Labial surfaces showed the highest dentin thickness while mesial and distal surfaces exhibited the least. The most common shape of canal cross section reported oval at CEJ, flat shape at middle 3rd, oval at apical 3rd. Majority of root apex deviated distally (55.2%) with laterally positioned apical foramen (59.4%). Accessory canals were reported in 40% of cases mostly at the apical third. Conclusion: Root morphology of permanent maxillary canines varies widely and endodontist should be aware of it due to the success of root canal treatment.
