Abstract:
To assess the age of a living person in forensic medicine, many different methods can be used, one of the most popular is the assessment of dental status, and the most accessible and widespread method of its assessment is the Demirjian method, based on the assessment of the stages of tooth development.
Objective:
To diagnose the age of majority using the Demirjian method in the Russian population.
Material And Methods:
The stages of development of the third molar on 645 OPTG from male and female individuals were analyzed using the Demirjian classification.
Results:
The results of the study showed that it is possible to determine the fact of the 18th birthday with a 70% probability by the stage of development of the G tooth. According to the stage of development, H is 98% likely to conclude that the subject is of age.
Conclusion:
The Demirjian method for estimating third molars can be successfully used for a comprehensive assessment of the fact of reaching adulthood in the Russian population.
