RESUMO

Morphological and topographic knowledge of the mandibular canal is paramount during dental procedures in the jaw, as structures that go through this canal must be preserved. The aim of this study was to analyze morphologic and morphometrically the course and relations of the mandibular canal of both male and female adults, belonging to two different groups of ages. The sample was composed of 300 panoramic radiographs shared in 4 groups: Groups F1 and F2: female gender (ranging between 18-40 years and above 40 years, respectively); Groups M1 and M2: male gender (ranging between 18-40 years and above 40 years, respectively). Seven linear vertical measurements were performed in the radiographs to describe the course and relations of the mandibular canal with anatomic structures of jaw. Mental foramen horizontal position and proximity relation between the mandibular canal and the roots of the inferior teeth were also evaluated. Statistically significant differences were observed in four of the measurements between genders. However, there was no difference between groups of age for any of the measurements. The most frequent position of the mental foramen was between the roots of the inferior pre-molars; and the mandibular canal shows proximity relation to the roots of the inferior third molar, moving gradually away from the roots of the other teeth. The results suggest that the measurements related to mandibular canal performed in this study can be influenced by the gender but are independent of age
