Age and Gender Estimation Through Dental X-Ray Analysis

The most frequently used, long-lasting, and well-preserved human body part in forensic and anthropological investigations is the tooth. The tooth is said to be a great way to determine the biological profile of unidentified remains. A piece of evidence in cases where the recovered dead bodies are mutilated and dismembered beyond recognition, such as bomb blasts, terrorist attacks, airplane crashes, and other mass disasters. Results could not be available for many days while forensic experts use their skills to manually determine each person’s age and gender. A fully automated method was developed to ascertain the age and gender of a person based on digital images of their teeth. The procedure of determining gender and age from images of individuals is done methodically since teeth are a strong and unique part of the human body that persists for a longer length of time and exhibits less sensitivity to change in its natural structure. Dental evidence is regarded as valuable for determining sex when other body parts are insufficient, critical to the body, or unavailable. The main techniques for determining sex from teeth are visual/clinical, microscopic, and sophisticated techniques. This review article covered the difficulties and approaches like GNN which is used for sex determination from teeth.
