ABSTRACT

In this study, it is aimed to compare the retarded, average and accelerated developmental changes of girls and boys for evety sex and age separately, in respect to Greulich and Pyle Atlas basically. The material of this study has been constituted with 698 hand and wrist radiograms obtained from 358 girls and 340 boys among 10-15 years of age. The individuals were divided in to groups, according to the differences between their chronological and skeletal ages for every chronological age group by means of their developmental situation as retarded, average or accelerated. Then the difference between girls and boys, and the differences among every chronological age group were compared by means of development groups. As a result according to Greulich and Pyle Atlas, girls were found more retarded for their skeletal ages relative to their chronological ages where the boys were accelerated.
