TINEO, Francisco et al. Estimacion de la edad cronológica con fines forenses, empleando la edad dental y la edad osea en niños escolares en maracaibo, estado zulia. Acta odontol. venez [online]. 2006, vol.44, n.2, pp.184-191. ISSN 0001-6365.

The aim of this paper was to determine if the combination of the skeletal age calculated by the Greulich and Pyle method, and the dental age estimated by using the Demirjian and cols. method in a multiple regression equation is more precise and efficient for predicting the chronological age of children at school age. A sample of thirty individuals was selected (16 boys and 14 girls) without systemic illnesses and with height and weight according to their age and sex. The estimation of the skeletal age by means of the Greulich and Pyle method and the dental age estimation according to the Demirjian and cols. method were both carried out. The skeletal age was 0,5 year less than the real chronological age. There was an overestimation of 0,9 years in the dental age with regard to the chronological age and the dental age was 1,5 years higher than the skeletal age. We obtained a strong positive correlation (r = 0,929) between the chronological age and the dental age; and of (r = 0,918) between the chronological age and the skeletal age, without regarding their sex. It was evident that the combination of the dental age and the skeletal age increases the precision for the calculation of the chronological age, when compared with the regression equations used by the dental age and the skeletal age, as independent predicable variables, based on their respective determination coefficients (R²).
