Assessment of root morphology of human mature permanent mandibular canines using cone beam computed tomography: an institutional retrospective study
Assessment of root morphology of permanent mandibular canines
Abstract
Introduction:-Root morphology of mandibular canine vary widely in different population.
Aim:- The objective of present retrospective study is to observe the root morphology of permanent mature mandibular canine in Eastern Indian subpopulation.
Materials and Methods:- In this study 212 permanent mandibular canines of both male and female patients (14-50 years age group) collected from a tertiary health care centre were processed through iRYS NNT viewer software and evaluated for the variation in the root morphology.
Results:- Statistical analysis revealed that 85.4% of mandibular canines have single root with single canal. Among other canal configuration Type 3 was most commonly found while Type 2 was least common. significantly larger root dimensions observed in males than females. Labial surfaces showed highest dentin thickness while mesial and distal surfaces exhibited the least. The most common shape of canal cross section was reported oval at CEJ, flat shape at middle 3rd, oval at apical 3rd. Majority of root apex exhibited no curvature with laterally positioned apical foramen. Accessory canals were reported in 32.5% cases mostly at the apical third.
Conclusion:- Due to wide variation in root morphology of mandibular canines in different population, dentist should aware of it for successful endodontic management.
