The knowledge of the morphology and topography of the mandibular canal is important for performing dental treatment as preservation of the mandibular canal can get easily involve or damaged during extraction of mandibular third molars, implant surgeries, orthognathic surgeries, and reduction and fixation of fractures. The aim of this study was to evaluate morphometric analyses of the mandibular canal in relation to the age group and gender by using panoramic radiography. The mean values of all measurements are greater in males than females and the ratio between the distance are seen greater in females in R1 and R3 and in males R2 is greater than males. Panoramic radiography was efficient for making the measurements and evaluating the course of mandibular canal
