CORRELACIóN ENTRE RESULTADOS DE RADIOGRAFíA CERVICAL LATERAL Y RADIOGRAFíA DE MANO-MU?ECA EN LA ESTIMACIóN DE EDAD OSEA EN NI?AS

摘要

In the framework of odontological practice, the assessment of skeletal maduration is vital for decision-making concerning orthodontic and orthognatic treatments, specially in commonly performed cephalometric radiographs. Our purpose was to determine the correlation between bone age analysis by applying Fishman method to hand-wrist radiograph, and Cervical Vertebrae Maduration Stages Method (CVMS) to lateral cephalometric radiograph. A prospective study was conducted in a sample oí24 girls lodged at Residencia de Ni?as Hogar Madre Teresa Bacq, Concepción, Chile, whose ages ranged from 6 to 14 years. Girls underwent lateral cephalometric and hand-wrist radiographs for estimating bone age according to both foregoing methods (CVMS and Fishman). The Chi-square statistical analysis revealed a strong dependency between variables as well as a correlation of 0,753 per cent according to Spearman coefficient, thus demonstrating a strong and positive correlation between both methods.
