Background. and Aim: The retromolar canal is an anatomical structure of the mandible and a type of bifid inferior alveolar canal. The retromolar canal might conduct accessory innervation to the
mandibular molars or contain an aberrant buccal nerve; thus, this canal is of clinical significance. The aim of this study was to evaluate the prevaleirce of retromolar canal on cone-beam computed tomography [CBCT] scans. Materiols and Methods: In this descriptive-analytical study, 151 retromolar canalsin 102 patients [102 unilateral and 49 bilateral] with third molar teethrequiring CBCT were evaluated. The scans were evaluated for presence of the retromolar canal and linear measurements [distance to second molar, height and width] were made. The data were analyzedby independent t-test and chi square test.
Resultsz The prevalence of retromolar canal was 7.3% [n=11] . With regard to linear measurements, the mean distance from the retromolar canal to the second molar was 12.76 +/- 4.3mm. The mean height of the canal was 6.66 +/- 2.18mm, and the'mean width was 1.7 +/- 0.6mm. The presence of retromolar canal was not statistically correlated withsex, side of the jaw or age [P: 0.146] .
