OBJECTIVES
This study aims to assess the accuracy of age estimation according to two cut-off points of Demirjian's developmental stages (G and H) in the wisdom teeth, using panoramic radiographs from Colombian and Mexican teenagers.
STUDY DESIGN
The degree of maturation of the third molars was classified according to Demirjian in 8 stages (from A to H) by a blinded trained assessor. The sensitivity, specificity and efficacy of two cut-off points (G and H) were calculated for both samples.
RESULTS
The orthopantomographies of 316 subjects, 171 Colombians (54.1%) and 145 Mexicans (45.9%), were analyzed. The stage H was found to be the best threshold for detecting juveniles (because the high specificity) in all the third molars assessed. The specificity was higher for lower third molars than for upper third molars, but no asymmetrical discrepancy was noted.
CONCLUSIONS
The stage H is the best cut-off point for detecting the adulthood when a high-specificity test is required.
目的
本研究旨在利用哥伦比亚和墨西哥青少年的全景X线片，根据智齿的两个Demirjian发育阶段切点（G和H）评估年龄估计的准确性。
研究设计
由一名经过盲法训练的评估者根据Demirjian方法将第三磨牙的成熟程度分为8个阶段（从A到H）。计算两个切点（G和H）在两个样本中的敏感性、特异性和有效性。
结果
分析了316名受试者的曲面断层片，其中171名哥伦比亚人（54.1%）和145名墨西哥人（45.9%）。在所有评估的第三磨牙中，发现阶段H是检测青少年的最佳阈值（因为特异性高）。下颌第三磨牙的特异性高于上颌第三磨牙，但未发现不对称差异。
结论
当需要高特异性检测时，阶段H是检测成年期的最佳切点。
