ABSTRACT

Objectives: Previous studies showed there were variations in the interforamina distance of mental foramen between races. The aim of our study is to determine the interforamina distance of mental foramen among Malaysian populations.

Materials and methods: A total of 503 orthopantomogram (OPG) radiographs were observed. Interexaminer calibration was estimated using the Kappa-Cohen formula. A sheet of transparent paper was superimposed on the panoramic film and the mental foramen was traced on it by using a fine marker pen. A vertical line marking the midline was drawn passing between the maxillary central incisors, the mandibular central incisors, or the nasal septum by using a ruler. The distance of the mental foramen from the midline was then recorded from both the left and the right side. The data were analyzed using chi-square test.

Results: According to our inclusion and exclusion criteria, 110 OPGs have been excluded and 393 OPGs were selected. In the Malay population, the most common interforamina distance for a male is between 55 and 60+ mm (n = 73, 54.8%). Also, the most common interforamina distance for a female is 55 to 60+ mm (n = 84, 50%). In the Chinese population, the most common interformina distance for a male is between 55 and 60+ mm (n = 60, 66.8%). Similarly, the most common interforamina distance for a female is between 55 and 60+ mm (n = 73, 53.8%). Among the Indian population, the most common interforamina distance for a male falls between 55 and 60+ mm (n = 53, 43.4%) and for a female as well (n = 50, 54%). According to the chi-square test, the results show that the study is statistically insignificant since the p-value is > 0.05 for both the male and female population.

Conclusion: There is no relationship between the interforamina distance and the ethnicity. The most common interforamina distance for all the races falls between 55 and 60+ mm.
