摘要

In the last few years, forced and unregistered childmarriage has widely increased into Turkey. The aim of this study was to test the accuracy of cut-off value of 0.08 by measurement of third molar index (I-3M) in assessing legal adult age of 18 years. Digital panoramic images of 293 Turkish children and young adults (65 girls and 128 boys), aged between 14 and 22 years, were analysed. Age distribution gradually decreases as I-3M increases in both girls and boys. For girls, the sensitivity was 85.9% (95% CI 77.1-92.8%) and specificity was 100%. The proportion of correctly classified individuals was 92.7%. For boys, the sensitivity was 94.6% (95% CI 88.1-99.8%) and specificity was 100%. The proportion of correctly classified individuals was 97.6%. The cut-off value of 0.08 is a useful method to assess if a subject is older than 18 years of age or not.
