ABSTRACT

Background: The mental foramen is a small foramen situated on the anterolateral aspect of the body of mandible, through which the mental nerve and blood vessels pass. The mental nerve innervates the lower canines and premolars.
Purpose of study: As the mental foramen is an important landmark to facilitate surgical, local anaesthetic, and other invasive procedures, the present study was aimed to elucidate its morphologic and morphometric features.
Results: The shape of the mental foramen was round in 40 right sides (44.9%) and 44 left sides (49.4%).  The longitudinally oval foramen was found in 49 right sides (55.1%) and 45 left sides (50.6%). The direction of opening of the foramen was posterosuperior in most of the cases (77.5% on the right side and 83.15% on the left side). The study measured an average vertical diameter of 2.72mm and 2.75mm whereas the horizontal diameter was 3.66mm and 3.54mm on right and left foramina respectively.
Conclusions: Variations exist in the position, shape, and size of mental foramen in different population groups. It is essential to be aware of the possibility of these anatomical variations while planning surgery in that region to avoid nerve damage and also to enable effective mental nerve block anaesthesia.
Key words: Mental foramen, Shape, Diameter, Direction of opening.
