-

 AGE ESTIMATION 

INTRODUCTION :

  • Radiology plays an important role in human age determination
  • Dental radiography is a non-destruction and simple technique used daily in dental practice 
  • Age estimation in children can be based on radiographic analysis of developmental stages of dental elements since:

  1. Strong genetic control
  2. More reliable in predicting chronological age than other osteological indicators






NEED FOR IDENTIFICATION:

  • A competent forensic death investigation of human remains has 4 goals :

  1. Determination of the means
  2. Manner
  3. Cause of death
  4. Identification of the remains


METHODS:
DEMIRJIANS METHOD:

  • To assess the developmental stages of third molars from the mandible .
  • Eight stages (A-H) Plus 0 - absence 



CONCLUSION :

  • Teeth represent useful material for age estimation 
  • Development of each individual can be effected by :
  1. Genetic 
  2. Nutritional
  3. Climatic 
  4. Hormonal
  5. Environmental 




  • It has been reported that dental mineralisation is less affected by external factors when compared to bone mineralisation 
  • thus tooth is considered for determination of chronological age .
