Abstract

To determine the position of mental foramen based on the height from alveolar crest and lower border of the
mandible from CBCT scans. The purpose of the study is to determine the position of mental foramen based on
the height fromalveolar crest and lower border of the mandible from CBCT scans. Materials and methodsA
total of 50 CBCT scans were evaluated. The number, size and form of the mental foramen were recorded and
their three dimensional relationship with the mandibular premolars were observed and noted. The position of
each mental foramen relative to bony reference points were be measured, and distances from mental foramen
to the cement enamel junctions of the mandibular premolars were measured.Results:The average values were
obtained for the distance between the mental foramen and the alveolar crest, mental foramen to the lower border
of the mandible, the horizontal and vertical dimensions of the mental foramen. All of the individuals has a
single mental foramen which was ovoid in shape. The mean horizontal dimensions were (2.70±0.73)mm and
(2.73±0.72)mm on the right and left sides respectively. Vertical dimensions were (2.20±0.65)mm and
(1.86±0.16)mm respectively on the right and left sides. Mean distances from the mental foramen to alveolar
crest and the lower border of the mandible were (11.35±3.92,10.48±2.84) and (9.47±1.48, 9.72±1.38)
respectively. ConclusionThe average values obtained from the study help in understanding the anatomy and
position of the mental foramen better on CBCT. The detailed information about the relationship between mental
foramen and its surrounding structures will facilitate diagnostic and surgical procedures done in the oral and
maxillofacial region
