The purpose of this study was to evaluate the position and shape of mental foramen
in panoramic radiographs. For this study, panoramic radiographs were obtained from the
200 adults and evaluated the position and shape of mental foramen. According to various
positional changes in panoramic radiographs of the patients, the author also obtained
panoramic radiographs from the 100 adults and then evaluated the positional and shape
changes of mental foramen.
The following results were obtained:
1. Shapes of mental foramen were observed elliptical(43.3%), round or oval(42.5%),
unidentified(7.5%) and diffuse(6.7%) type in descending order of frequency.
2. Horizontal position of mental foramen were most frequently observed at the 2nd
premolar area(54.2%), and area between the 1st premolar and 2nd premolar(43.1%), area
between the 2nd premolar and 1st molar(2.7%) in descending order of frequency.
3. Vertical position of mental foramen were most frequently observed at the inferior of
apex(88.2%), and at apex(9.7%), overlap with apex(1.9%), superior of apex(0.2%) in
descending order of frequency.
4. According to various positional changes in panoramic radiographs of the patients,
shape changes of mental foramen were more obviously observed at the forward 10mm
and chin down 10¡Æpositioned panoramic radiographs. And changes of horizontal and
vertical position were observed in similar to compared with normal positioned panoramic
radiographs.
