THE MENTAL FORAMEN - HORIZONTAL POSITION AND SHAPE IN SOUTHEAST SERBIAN POPULATION
Abstract
The mental foramen is an important anatomic landmark in dentistry, and the knowledge about its accurate location is important in gaining local anesthesia, during surgical and endodontic procedures, as well as in forensics. The purpose of this study was to determine the most common position and shape of the mental foramen in the Southeast Serbian population. Three hundered panoramic radiographs were analyzed and the horizontal position of the mental foramen was determined according to the reference lines drawn at the longitudinal axes of the first and the second premolar and the mesial root of the first molar. In 62% of the cases mental foramen was between longitudinal axes of the first and the second premolar, in 21% was in line with the second premolar, in 9% in line with the first premolar, in 8% between the axes of the second premolar and the first molar. The most common shape was round (54%). The horizontal position and shape were asymmetrical in 26% and 32% of the cases, respectively. The most common position of the mental foramen was between the first and the second premolar, while the most common shape was round. Knowledge about variable positions of the mental foramen is important in diagnosis and clinical procedures in the region of the mandible.
