Comprehensive Chart for Dental Age Estimation (DAEcc8) based on Demirjian 8-teeth method: Simplified for operator...

Area of Science:

• Forensic Odontology
• Anthropology
• Human Biology

Background:

• Juvenile crime is rising globally, necessitating reliable age estimation methods.
• Radiographic dental age estimation (DAE) is crucial for legal and forensic purposes.
• Existing DAE methods, like Demirjian's modification, can be complex and difficult to apply.

Purpose of the Study:

• To develop a comprehensive and user-friendly dental age estimation chart (DAEcc8).
• To integrate existing DAE tables and regression equations into a single, accessible tool.
• To improve the pictorial representation of developmental stages for better accuracy.

Main Methods:

• Developed DAEcc8 by combining Chaillet and Demirjian's modification of the Demirjian method.
• Incorporated updated pictorial representations based on Demirjian and Nolla's classifications.
• Defined scoring for each developmental stage in males and females.
• Utilized regression equations for final age computation.

Main Results:

• DAEcc8 consolidates all necessary data and equations for DAE.
• The chart features improved pictorial representations for easier stage identification.
• The method is designed for straightforward comprehension and execution.

Conclusions:

• DAEcc8 offers a more accessible and efficient tool for dental age estimation.
• The proposed chart has potential applications in forensic dentistry and education.
• This method can aid in accurately determining the age of juveniles in conflict with the law.
