Survey of Anatomy and Root Canal Morphology of Maxillary First Molars Regarding Age and Gender in an Iranian Population Using Cone-Beam Computed Tomography.

Abstract

INTRODUCTION: The purpose of this study was to investigate the root and canal morphology of maxillary first molars with regards to patients' age and gender with cone-beam computed tomography (CBCT). METHODS AND MATERIALS: A total of 149 CBCT scans from 92 (67.1%) female and 57 (31.3%) male patients with mean age of 40.5 years were evaluated. Tooth length, presence of root fusion, number of the roots and canals, canal types based on Vertucci's classification, deviation of root and apical foramen in coronal and sagittal planes and the correlation of all items with gender and age were recorded. The Mann Whitney U, Kruskal Wallis and Fisher's exact tests were used to analyze these items. RESULTS: <0.05). The prevalence of apical foramen deviation in mesiobuccal and palatal roots statistically differed with gender. CONCLUSION: The root and canal configuration of Iranian population showed different features from those of other populations.
