ABSTRACT

AIM: The aim of this study was to develop an age estimation table based on mineralization stages of third molars in a survey in the state of Alagoas, Brazil. Forensic dentistry has largely contributed to solve age estimation cases. Radiographic study on tooth mineralization stages has shown major importance on age estimation with forensic application.
METHODS: This investigation was a crosssectional study developed at the clinic of the local branch of the Brazilian Dental Association in Alagoas. Three hundred and twelve patients of both genders aged 9 to 21 years were enrolled. Three calibrated examiners (kappa=0.789, p<0.001) determined the mineralization stages of each third molar from radiographs collected in the survey. The age of each patient was also recorded.
RESULTS: A third molar chronological mineralization table based on the study's survey was developed. There was correlation (Spearman=0.869; p<0.01) between real and estimated ages, mainly when both upper and lower third molars were considered together.
CONCLUSIONS: It is important to develop regional age estimation tables based on local surveys mainly considering ages of forensic interest.

Keywords: age determination by teeth, molar third, radiography, panoramic.
