Using optical-scanner (OPTOCOM) and radiogrammetric measurements on mandibular permanent teeth, root length alone affords sex-discriminatory effectiveness equal to or exceeding conventional crown diameters. Combinations of root length and crown dimensions yield up to 80% accuracy in sexing with as few as two teeth, and discriminatory effectiveness of 87% with mandibular teeth alone.
通过对下颌恒牙进行光学扫描仪（OPTOCOM）和放射测量，仅牙根长度的性别判别效果就等于或超过传统的牙冠直径。牙根长度和牙冠尺寸相结合，仅用两颗牙齿进行性别鉴定的准确率高达80%，仅下颌牙齿的判别效果为87%。
