The purpose of this study was to verify whether the Greulich & Pyle (GP), Greulich & Pyle Visual (GPV) and Tanner & Whitehouse (TW) methods for estimating skeletal age could be applied in the Brazilian population, and which of these three methods could be considered more reliable when compared with the chronological age of the individuals. This study was based on one hundred and sixty volunteers (80 females and 80 males) with ages between 6 years and 10 months and 14 years and 9 months. The results showed that for the GP method, the correlations with chronological age were 0.95 for males and 0.97 for females. For the GPV method, the correlations were 0.96 and 0.97, respectively and for TW, 0.96 and 0.97. The results showed that the Greulich & Pyle, Greulich & Pyle Visual and Tanner & Whitehouse methods presented high correlation values when compared with the chronological age of the individuals. Corrective factors were established to make these methods applicable to the Brazilian population.Downloads
