RESUMO

Bone mass aquisition in childhood is an important factor in fractures and osteoporosis prevention. Many studies show correlations between bone mineral densities and mandibular radiomorphometric indices in adults. The objective of this research was to verify if such a correlation exists also in growing individuals. Spine and whole-body densitometries and panoramic radiographs of 94 healthy children - 42 boys and 52 girls - and of 35 children with diagnosis of Osteogenesis Imperfecta types I, III and IV - 16 boys and 19 girls - aged from 5 to 18 years were evaluated. Five mandibular radiomorphometric indices were tested: mandibular cortical index, visual estimation of cortical width, mentual and antegonial indices and antegonial depth. This study showed correlation between visual estimation of cortical width, mentual and antegonial indices with bone mineral densities and skeletal ages in healthy children. Children with diagnosis of Osteogenesis Imperfecta showed more corticals classified as C3 and thin, and mentual and antegonial indices were thinner than in healthy children, even in those who were already in pamidronate treatment. Most of the children with normal densitometric diagnosis had corticals classified as C1 and not-thin.
