Morphometric Analysis Of The Ramus Of The Mandible For Sex Determination

Objective The shape of the condyle, coronoid, and the intervening sigmoid notch is unique due to attachments and direction of pull of temporalis muscle, different chewing habits, hormones, etc. So morphometric variation of these mandibular landmarks can be used in individual identification. Material And Methods The study was carried out on 500 panoramic view images. Visual tracing assisted assessment of thousand sides (left and right) was done. Sexual dimorphism of left and right mandibular ramus parts (sigmoid notch bordered by coronoid and condylar process). The shape of coronoid process, condyle, and sigmoid notch were interpreted. Results The most prevalent shape of sigmoid notch was wide variant (41.2%), condyle was convex type (50%) and coronoid was round (53.4%). Condyle and coronoid showed asymmetry between right and left with p-value 0.001 and 0.019, respectively. This study has illustrated that triangular-shaped coronoid was more in females (p-value 0.012). Conclusion Sexual dimorphism is observed in the shape of the mandible due to masticatory activity at the point of insertion of temporalis muscle, biting force, hormones, and various genetic reasons. The results have exemplified that the morphometric variation of condyle, coronoid and sigmoid notch can be used as a tool for personal identification.

“…5: The morphometric parameters taken on OPG to train the AI However, it is worth noting that the accuracy level for males was relatively lower, which is consistent with findings from previous studies. 22,23 Furthermore, logistic regression, another statistical method used in this study, exhibited an overall accuracy rate of 69.9%. In terms of gender classification, logistic regression correctly identified 67.4% of females and 72.2% of males.…”

“…Jaw bone and teeth are immune to wear even under extreme conditions and hence play a vital role in post-mortem identification. 19 The teeth which are least affected by dental caries are the canine teeth, hence it is retained in the jaw for the longest period after death, it also shows higher degrees of sexual dimorphism and hence can be used in gender determination of the living or the dead. 20 A study conducted by Patil et al 21 employs Artificial Neural Networks (ANN) for gender determination and compares the obtained results with logistic regression and discriminant analysis using mandibular parameters (Figure 5) as inputs.…”

Revolutionary advancements in dentistry have been brought about by robotic advancements that mimic the functions of the human brain. Over an extended period, both dental and medical documentation has undergone computerization, with cloud servers serving as reliable backups. These records have played a crucial role in identifying victims of major catastrophes such as the World Trade Centre disaster and the Indian Ocean tsunami. Often, in these cases, the bodies are severely damaged and unidentifiable, except for the remaining teeth and the resilient jawbone, which exhibit remarkable resistance to harsh conditions. These elements have proven to be vital in the process of identifying disaster victims. To conduct the present review, extensive online research was performed using databases such as Google Scholar, PubMed, Medline, and IEEE Xplore, up until December 2022.
