Sažetak
Estimation of real age of an individual is one of the main challenges in forensic science. For penal and criminal law, as well as general legislation, it is necessary to determine whether the person is older or younger than 18 years, in other words an adult or a minor? This becomes especially important when an individual lacks personal documents or other means of identification. Aim of this study was to evaluate applicability of third molar in assessing 18 years of age in Croatian individuals. Cameriere's third molar maturity index (I_3M) of 0.08, by measuring of the open apices of the teeth, was verified in sample of 1336 Orthopantomograms (OPGs) aged between 14 to 23 years. Chronological age gradually decreases as I_3M increases in both genders. Males showed statistically significant advanced maturation when I_3M was between 0.0 and 0.3 value. The results show that the sensitivity of the test for 0.08 value was 84.3% (95%CI 80.6%, 87.5%) and 91.2% (95%CI 88.7%, 93.1) in females and males, respectively. Specificity was 95.4% (95%CI 92.5%, 97.5%) and 91.9% (95%CI 88.8%, 94.3%) in females and males, respectively. The proportions of accurately classified males were 88.8% and 91.5% for females. The estimated post-test probabilities, of individuals who scored positive on the test (i.e., I_3M < ; 0.08) as having 18 years of age or more, were 94.5% and 96.5% in females and males, respectively. Therefore, the probability that a Croatian individual, positive on the test (i.e., I_3M < ; 0.08), was 18 years of age or older were 94.5% and 96.5% in females and males, respectively.
