In forensic practice knowledge of chronological age (CA) is an important factor, and it can be estimated by several methods. Some are complex, expensive and time consuming. Dental Age (DA) estimation by radiographic methods is easy and inexpensive, it has shown to be consistent with chronological age (CA), with variations according to sex and race. The objective of this study was to estimate the concordance between DA and CA in Mexicans. This is a cross sectional, observational study, in which a standardized dental resident reviewed 88 Orthopantomographies (44 female, 44 male), blinded to CA, of the Orthodontics School Files of the Universidad Autónoma de Sinaloa, the population was 3 to 16 years of age. The main difference in months between DA and CA was 3.36 (p=0.384) and 94 % of concordance, the analysis by sex for males showed a main difference of 5.16 (P=0.785) and 96 % concordance; for females it showed 7.32 (P=0.095) and concordance of 92 %. In conclusion the DA according to Demirjian is a reliable method to estimate CA in these patients.
