Forensic age estimation from teeth is crucial for identification. The Average Stage of Attrition (ASA) method proved most effective for adult age determination compared to microscopic techniques.

Area of Science:

  • Forensic Odontology
  • Anthropology

Background:

  • Accurate age estimation is vital in forensic identification.
  • Dental metrics offer reliable indicators for determining an individual's age.

Purpose of the Study:

  • To evaluate and compare the efficacy of three distinct methods for adult age estimation from teeth.
  • To identify the most accurate and practical method for forensic applications.

Main Methods:

  • Comparative analysis of three age estimation techniques: Johanson method, Kashyap and Koteswar Rao method, and the Average Stage of Attrition (ASA) method.
  • Involved microscopic measurements for Johanson and Kashyap methods, and clinical observation for the ASA method.
  • Study sample comprised 100 patients.

Main Results:

Related Experiment Videos

  • The Average Stage of Attrition (ASA) method demonstrated superior accuracy in adult age determination.
  • Kashyap's technique yielded unsatisfactory results more frequently.
  • Overestimation of age was commonly observed with mandibular teeth and in samples from female individuals across all methods.

Conclusions:

  • The ASA method is recommended as the most effective clinical approach for forensic age estimation from teeth.
  • Further research is warranted for Kashyap's method due to measurement challenges.
  • Sex and tooth type (mandibular) can influence age estimation accuracy.
