Morphological Changes and Gender-Based Differences in Human Dry Mandible
Abstract
Introduction: The natural ageing process can cause changes in the teeth and gums, which can further impact the structure and function of the mandible. The major parts of a mandible are the condylar process, the angle of the mandible, and the mandibular canal. These anatomical structures play a key role in various branches of dentistry like orthodontics, prosthodontics, forensic dentistry, and maxillofacial surgery.
Methods: The present study included 100 dry adult human mandibles of known genders. We measured the condylar volume with a vernier calliper, the angle of the mandible with a protractor, and the length of the mandibular canal by passing a probe through the mandibular foramen to the mental foramen.
Results: We found that the angle of the mandible was higher in females, while the condylar volumes were greater in males. The length of the mandibular canal did not show much difference in the two genders. The mean value of mandibular canal length in adult females was greater than that of males, and the p value was greater than 0.05, making this difference statistically insignificant (p = 0.1318). There was no correlation between gender and mandibular canal.
Conclusion: The study showed that two parameters (condylar volume and angle of mandible) can undoubtedly be used for assessing sexual dimorphism and can also be an aid in various branches of dentistry with respect to diagnoses, treatment plans, executing surgeries, rehabilitation, and facial reconstructions.
