Resumo
Objective: It was evaluated the position and shape of mental
foramen on digital panoramic radiographs in a Brazilian sub-
population. Material and Methods: Five hundred and eighteen
panoramic radiographs were consecutively selected from a sec-
ondary database from a private radiology clinic and analyzed
according to age, gender and symmetry. Two specialists in den-
tal radiology determined the horizontal and vertical positions
and the format of 1036 mental foramen. Results: The highest
frequency of the mental foramen was located between the long
axis of the first and second premolars (55.89%). There was no
difference in horizontal position in relation to gender and age. Symmetries were observed in 68.91% of the sample. The vertical
positioning of the foramen showed a common location below
the apex of the first and second lower premolars (55.31%). Dif-
ference in vertical relationship was observed only in patients
aged 10 to 20 years. Symmetries were observed in 84.36% of
cases. A large number of mental foramen had undefined/irregu-
lar contours (62.74%), with symmetries in 68.15%. Conclusion:
The mental foramen is commonly presented below and between
the first and second premolars and with undefined/irregular
format.
