Abstract

 Introduction: In this study, Greulich-Pyle (GP) atlas that have been used for evaluation of BONE AGE frequently, was used for assessment 0f BONE AGE of Iranian children in Kurdestan(western Iran).Materials & methods: Plain radiographies of left hands and wrists of 248 healthy children (111 boys and 137 girls with mean age 10.15 years old) between 7 to 15 years of age, who were students of primary and guidance school in Sanandaj, were taken. The radiographs were analyzed by a radiologist uninformed of the children’s age using the standards of Greulich and Pyle. Differences between BONE AGE and chronologic age were calculated and the mean differences were compared by paired T-test and correlation coefficient among subgroups of children on the basis of sex and age and their fathers' jobs.Findings: Mean SKELETAL AGEs proved a delay of %12.6,%12.4,%3 than the mean CHRONOLOGICAL AGEs in the 7,8,9 years age groups, respectively and advanced %2,%5.4 and 51.4 in the 10,11,12-15 years age groups. SKELETAL AGE in 11 years age groups of boys was advanced, while delayed in other age groups. In 7-9 years age groups of girls, BONE AGE showed a delay copared to that of the CHRONOLOGICAL AGE and the ones of over 10 years showed an advance. In our study, BONE AGE showed a delay in children whose fathers were workers (p<0.05), but in children whose fathers free or formal jobs no significant statistical differences were seen.Conclusion: According to the findings, using the standards of Greulich and Pyle to determine the BONE AGE in 7-15 years old children must be considered with necessary caution, particularly in boys of late childhood.
