A CBCT Study to Evaluate the Root and Canal Morphology of Permanent Maxillary First Molars in Children

Abstract

Introduction: For the correct diagnosis and endodontic therapy, a complete understanding of root canal morphology is required. One of the causes of endodontic failure is the inability to identify every canal in the root canal system; the second mesiobuccal canal (MB2) in the permanent maxillary first molar is the most commonly missed canal. Studies examining the root canal differences in pediatric Indian populations’ permanent maxillary first molars are somewhat uncommon. Aim: Cone-beam computed tomography (CBCT) will be used to assess the root and canal morphology of permanent maxillary first molars in the pediatric Indian population. Materials and methods: In the age range of 7–13 years, 25 children’s CBCT pictures (50 images) were gathered from the institutional database and private diagnostic facilities. SCANORA® software was used to reconstruct the CBCT pictures, and Statistical Package for the Social Sciences (SPSS) for Windows was used to evaluate and analyze the data. Results: The roots of each permanent maxillary first molar were distinct. And all of the palatal and distobuccal roots were found to have a single root canal (100%), whereas the mesiobuccal roots were found to have a single root canal in 80% of cases and a double root canal in 20% of cases. The Vertucci type II structure, followed by types IV and V, was the most prevalent in roots with two channels. Conclusion: Within the constraints of this investigation, we came to the conclusion that the permanent maxillary first molar root canal configuration varied among the patients from the pediatric Indian population.
