Estimation of Chronological Age from Permanent Teeth Development

چکیده
This paper compares traditional averagesbased model with other various age estimation models in the range from the simplest to the advanced ones, and introduces novel Tabular Constrained Multiple-linear Regression (TCMLR) model. This TCMLR model has similar complexity as traditional averages-based model (it can by evaluated manually), but improves the mean absolute error in average about 0.30 years (approx. 3.6 months) for males, and 0.18 years (approx. 2.2 months) for females, respectively. For all models, the chronological age of an individual is estimated from mineralization stages of dentition. This study was based on a sample of 976 orthopantomographs taken of 662 boys and 314 girls of Czech nationality aged between 2.7 and 20.5 years.

Introduction: Like other measures of human development, dental development is not in complete accordance to chronological age. Investigations show that dental age can be affected by gender, race, systemic conditions, and some other factors and consequently, be different in people of the same chronological age. A correct estimation of dental age and its development in children is of great import...

Introdouction: Age estimation is an important issue in forensics, particularly for treatment planning and determining patients’ rights. Radiographic evaluation of the third molar developmental stage is a significant criterion for age estimation. The pattern of tooth development is largely heritable and varies from race to race. The objective of this study was to radiographically examine and com...
متن کاملDental Age Estimation in Children: A Review
Teeth are extremely useful in the estimation of age and are preferable over other skeletal methods As they are durable in archaeological contexts, have minimal remodeling, and the growth of permanent and deciduous teeth continues over the entire juvenile period [1,2]. Formation of deciduous teeth begins in utero at about 4 months and permanent teeth complete formation at approximately 25 years ...
