Abstract
The purpose of this study was to compare the epiphyseal events of the proximal phalanx of the thumb with the medial and distal phalanxes of the third finger in the determination of the bone age. The sample comprised 131 hand-wrist radiographs of males and females selected from the archive of the Orthodontics Clinic of the School of Dentistry of Araçatuba – UNESP and from PROFIS/Hospital for Rehabilitation of Craniofacial Anomalies-USP. The ossification centers were analyzed by only one examiner. The comparison between the osseous events of the proximal phalanx of the thumb and the medial and distal phalanxes of the third finger has shown a 91.6% agreement. Evaluation of the radiographs that did not show any agreement revealed that 1.5% presented the thumb in a more advanced maturational stage when compared to the third finger, while 6.8% showed a more advanced level of bone development when the third finger was analyzed. Comparison using the McNemar test (p = 0.07) revealed no statistically significant difference in the determination of bone age when either the first or third fingers were used. The findings show that the epiphyseal stages are coincident and, therefore, can be used independently in the evaluation of maturational stage.
