Accuracy of a cut-off value based on the third molar index: Validation in an Australian population.

摘要: According to Recommendation N°196 of the Australian Law Reform Commission (ALRC), age at which a child reaches adulthood for purposes criminal law should be 18 years in all jurisdictions. With specific reference majority, only tooth with development spanning adolescence (and thus legally relevant age) is third molar, limits number methods that can applied from those available published literature. The aim present study test accuracy molar index (I3M=0.08), based on correlation between chronological and normalized measures open apices height mandibular order assess legal adult years. Digital orthopantomographs 143 living subjects (72 boys 71 girls) are analyzed. results demonstrate sensitivity 0.90 girls; associated specificity values 0.85 0.87 respectively. We conclude cut-off value I3M=0.08 statistically robust valid forensic application an population.
