title: Sex discriminatory effectiveness using combinations of root lengths and crown diameters.
abstract: 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.
