The aim of this study was to evaluate retromolar canal (RMC) according to side, sex, distance, and relation with the last tooth in cone bean computed tomography (CBCT). Methods. The sample consisted of 500 CTCB of individuals of both sexes, with a minimum age of 14 years. RMC course, morphology, length, angle, diameter, and distance from the RMC with the most distal molar were evaluated. Results. RMC was found in 17 (3.7%) patients, aged between 19 and 73 years. Twenty-one RMC were observed; 9 (42.85%) were present on the right side and 12 (57.14%) on the left side. Four individuals (23.52%) had RMC bilaterally; 12 (70.6%) were female, and 5 (29.4%) were male; and regarding the individuals with bilateral canals, 3 were female. Conclusions. Female and the left side presented a higher frequency of RMC. RMC presence and course were not related to the age. There was no association between RMC course, side, angle measurements, diameter, and distance to the last tooth in the dental arch.
