title: The relationships between dental age, chronological age and bone age in Turkish adolescents with constitutional delay of growth.
abstract: The aim of this study was to investigate the relationships between dental age and bone age in Turkish adolescents with constitutional delay of growth and compare them with a group of normal, healthy adolescents. Left hand and wrist radiographs and dental panaromic radiographs of 33 adolescents (25 boys and 8 girls) aged between 10 and 16 years with constitutionally delayed growth were assessed. The control group comprised 41 healthy adolescents (24 boys, 17 girls) aged between 10 and 16 years. Bone age was determined according to Greulich and Pyle; dental age was assessed using the Demirjian method. In the control group, no statistical difference was found between chronological, bone and dental ages. In the group of adolescents with constitutional growth delay, there was no significant difference between chronological age and dental age, but the differences between dental age and bone age and between chronological age and bone age were found to be statistically significant. It was found that Demirjian's dental age assessment is a valid method for scoring dental age in Turkish adolescents. Adolescents with constitutional delay of growth had dental maturation appropriate for chronological age, but not for bone age.
