Methods: Panoramic radiographs of a population including 45 men and 45 women which were aged between 51 to 79 years were assessed and statistically analyzed. Results: Analysis of data demonstrated that the average of measured distances in male were significantly higher than female except for the distance between the two mental foramina. It should be signified that the accuracy of gender specification with this method was ranged between 78 to 84.5 percent in female and between 80 to 89 percent in male.
