ABSTRACT
This study evaluated the applicability of the regression method for determining vertebral age developed by Caldas et al. (2007) by testing this method in children from low-income families of the rural zone. The sample comprised cephalometric and hand-wrist radiographs of 76 boys and 64 girls aged 7.0 to 14.9 years living in a medium-sized city in the desert region of the northeastern region of Brazil, with an HDI of 0.678. C3 and C4 vertebrae were traced and measured on cephalometric radiographs to estimate the bone age. The average age, average hand-wrist age and average error estimated for girls and boys were, respectively, 10.62 and 10.44 years, 11.28 and 10.57 years, and 1.42 and 1.18 years. Based on these results, the formula proposed by Caldas et al. (2007) was not applicable to the studied population, and new multiple regression models were developed to obtain the children's vertebral bone age accurately.
RESUMO
O objetivo deste estudo foi avaliar a aplicabilidade do método de análise para determinar a idade vertebral proposto por Caldas et al., 2007 em crianças de baixa renda. A amostra se constituiu de radiografias cefalometricas e carpais de 76 meninos e 64 meninas com idade entre 7,0 a 14,9 anos que vivem em zona rural de um município sergipano. Os corpos das vértebras C3 e C4 foram traçadas e mensuradas e em seguida as idades ósseas foram estimadas. A idade media estimada para as meninas foi de 10,62 anos e a idade óssea carpal foi de 11,28 anos; o erro médio de 1,42 anos. A idade media estimada para os meninos foi de 10,44 anos e a idade óssea carpal foi de 10,57 anos com erro médio de 1,18 anos. Baseado nos resultados, o modelo proposto por Caldas et al. (2007) não pode ser aplicada na população estudada, e portanto novos modelos de regressão foram desenvolvidos.
