Abstract:

Objective: To assess the number of canals and morphological patterns of mesiobuccal root of maxillary second molars based on Vertucci's classification analyzed by Cone Beam Computed Tomography (CBCT) scans in our patients. Study Design: Retrospective Cross sectional analytical study. Place and Duration: At Operative Dentistry Department, Islamic International Dental Hospital, Islamabad from 1st September 2020 to 1st January 2021. Methodology: Cone-beam computed tomography (CBCT) scans (PLANMECA, Finland) were used with image size 13 x 9cm (651 x 651 x 451 cm3), voxel size 200µm to include maxillary anatomy with 96 KV radiation dose, exposure time of 12.527 seconds and current of 9 MA. Slice thickness of 0.200mm was recorded. Axial, coronal and sagittal planes were used to evaluate root canal anatomy of maxillary second molars. Number of canals and morphological patterns as per Vertucci's classification were recorded in mesiobuccal root of maxillary second molars. Results: Out of 200 cone-beam computed tomography (CBCT) scans, 316 maxillary second molars met the inclusion criteria. Mesiobuccal root of maxillary second molars having one canal were found in 78.48% and 2 canals in 21.52%. Maximum frequencies of canals in mesiobuccal root of maxillary second molars as per Vertucci's Classification were found to have type I i.e. 78.5% followed by type IV in 16.5% and type II in 5%. Conclusion: Number of canals is variable for the mesiobuccal root of maxillary second molar. Single canal and Vertucci's type I is the most common canal configuration type in mesiobuccal root of maxillary second molars. Significant difference was found between gender and Vertucci's classification in mesiobuccal root.
