ABSTRACT
Objective: The objective of this study was to evaluate the morphology and associated pathologies of maxillary first molar using Cone beam computed tomography.
Study Design: Descriptive cross sectional study.
Place and Duration of Study: This study was conducted at the Department of Oral Biology, Rehman college of dentistry, Peshawar from 1st March 2016 till 30th April 2020.
Materials and Methods: A descriptive cross-sectional study was conducted using 128 Cone beam computed tomography scans at Rehman college of dentistry, Peshawar. The Cone beam computed tomography scans were evaluated for number of root canals, presence of caries, agenesis, anatomic abnormalities and ectopic eruption using 3D reconstruction of the images. Data collected was analysed by SPSS version 20
Results: In this study, 56.25% of the scans showed four root canals while 43.75% had 3 canals. Mesiobuccal canal-2 was more common in males (74.13%) compared to females. First molar teeth had a 47.65% prevalence of dental caries.
Conclusion: Within the limitations of this study, we conclude that mesiobuccal canal-2 is a common finding in the maxillary first molar with higher prevalence in males compared to females. Due to higher susceptibility of first maxillary molar to dental caries, there is a higher probability of missing the mesiobuccal canal-2 during endodontic treatment. Therefore, careful exploration of pulp chamber should be done to avoid treatment failure.
Key Words: cone beam computed tomography, maxillary first molar, mesiobuccal canal-2, dental caries.
