The purpose of this study was to evaluate the position and shape of mental foramen
in periapical radiographs. For this study, periapical radiographs of premolar areas were
obtained from the 200 adults. Accordingly, the positional and shape changes of mental
foramen were evaluated. The authors obtained radiographs according to changes in
radiation beam direction in periapical radiographs of premolar areas, and then evaluated
the positional and shape changes of mental foramen.
The following results were obtained:
1. Shapes of mental foramen were observed elliptical(34.3%), round or oval(28.0%),
unidentified(25.5%) and diffuse(12.2%) type in descending order of frequency.
2. Horizontal positions of mental foramen were most frequently observed at the 2nd
premolar area(55.3%), the area between the 1st premolar and 2nd premolar(39.6%), the
area between the 2nd premolar and 1st molar(3.4%), the
1st premolar area(1.0%), the area between the canine and 1st premolar(0.7%) in
descending order of frequency
3. Vertical positions of mental foramen were most frequently observed at the inferior
to apex(67.1%), and at apex(24.8%), overlap with apex(6.4%), superior to apex(1.7%) in
descending order of frequency.
4. Shapes of mental foramen were more obviously observed at the upward 10¡£
positioned periapical radiographs. And according to the changes of horizontal and vertical
position, they were observed similar to normally Positioned periapical radiographs.
