Abstract

This research aimed to study the correlation between the location of mandibular foramen and the gonial angle in Thai population. The samples of this study were 61 dry adult mandibles (31-76 years) including 48 males and 13 females obtained from the Faculty of Medicine, Khon Kaen University. The location of mandibular foramen was measured in the vertical and horizontal distances. The vertical distance was measured from the mandibular foramen to the occlusal plane of teeth and the horizontal distance is measured from the mandibular foramen to the anterior border of the mandibular ramus. The study found that the average of the gonial angle value is 118.01 ± 6.40 degrees, the average of the vertical distance from the mandibular foramen to the occlusal plane was 6.24 ± 3.50 mm. and the average of horizontal distance from the mandibular foramen to the anterior border of the mandibular ramus was 18.07 ± 3.07 mm. Multiple linear regression demonstrated that the gonial angle was significant negatively correlated with the horizontal distance from the mandibular foramen to the anterior border of mandibular ramus (p < 0.0001), but there was no significant correlation between the gonial angle and vertical distance from the mandibular foramen to the occlusal plane (p = 0.473).
