This study is aimed at finding the predictive accuracy of Demirjian's (D), modified Demirjian's (MD) and India specific age estimation methods (AA) Indian specific age estimation methods in 522 healthy children of Odisha population among 3-18 years. Correlations between chronological age (CA) and derived age (DA) by above mentioned methods were evaluated by Wilcoxon signed rank test and Pearson's correlation analysis. Analysis of mean absolute error concluded that D and MD predicted the CA with fair accuracy, whereas, AA had lower accuracy in Odisha children. Odisha specific polynomial regression formula, derived in this study is showing a strong correlation with CA (r=0.84). Comparison of mean absolute error of D, MD, AA and Odisha specific method indicated a better predictive accuracy of Odisha specific method.
本研究旨在探寻德米尔贾恩法（D）、改良德米尔贾恩法（MD）以及印度特定年龄估计方法（AA）在奥里萨邦3至18岁的522名健康儿童中的预测准确性。通过威尔科克森符号秩检验和皮尔逊相关分析评估按上述方法得出的实足年龄（CA）与推算年龄（DA）之间的相关性。平均绝对误差分析得出，D法和MD法对实足年龄的预测准确性尚可，而AA法在奥里萨邦儿童中的准确性较低。本研究得出的奥里萨邦特定多项式回归公式与实足年龄呈现出强相关性（r = 0.84）。D法、MD法、AA法与奥里萨邦特定方法的平均绝对误差比较表明，奥里萨邦特定方法具有更好的预测准确性。
