Root canal anatomy and morphology evaluation of mandibular molars according to gender by cone-beam computed tomography in Iranian population

Introduction: This study aimed to evaluate anatomy and morphology of mandibular permanent molars using cone-beam computed tomography (CBCT) in a selected Iranian population.Methods Materials: CBCT images 638 first second (322 males 316 females) were included this vitro study. Number roots root canals, Vertucci’s configuration each root, radix paramolaris (RP), entomolaris (RE), C-shaped canals determined both genders. Data analyzed by Pearson-Chi square test SPSS (V.22) software (P = 0.05).Results: The most common distal type I for Among 266 molars, 97.3% teeth had two roots, 0.75% RP 1.87% RE. All RE I. found 1.12% all male population, significantly at the left side (P=0.045). 372 94.08% 0.53% 0.26% prevalent canal mesial was III (52.96%) with significant difference between right (P=0.006) (P=0.049). 5.64% more specifically detected group. Significant observed genders (P=0.024) (P=0.009).Conclusion: II configurations while predominant RE, RP, channels not population their prevalence higher among population.
