A pilot study of the mandibular angle and ramus in Indian population

To evaluate the mandibular angle and to analyze the relationship of the angle and height & breadth of the ramus of the mandible to the gender, so as to study its role in the anthropological diagnosis. The angle, height and breadth of the ramus of adult dry human mandibles of both sexes were measured using a goniometer. The values obtained were analyzed statistically. The present study showed a statistically significant difference in the mandibular angle as well as height of the ramus between both the sexes. The mean mandibular angle of Indian population when compared to that of European population was found to be lower by 9 degrees. The findings of this study might be useful in providing anthropological data that can also be used in dental and medical practice. However, the Indian mandible can be used for sexual dimorphism as is usual in anthropological work; it appears to possess important unfavourable anatomic factors that may predispose the individuals to difficult laryngoscopy or intubation.
