Abstract The mineralisation of third molars is one of the main criteria for dental age estimation of living subjects in criminal proceedings. Since the mineralisation of third molars is usually completed by the age of 19 or 20 years, this feature cannot be used to ascertain whether a person has attained the forensically relevant age of 21 years. This study examined whether determination based on an orthopantomogram of a combination of features relevant to dental age estimation of adults, supplies forensically useful information for ascertaining whether a person has attained 21 years of age. The features considered include the DMFT index of all permanent teeth, the DMFT index of all permanent teeth excluding third molars, the DFT index of third molars projecting beyond the occlusal plane, the eruption of third molars and the periodontal recession of second molars. A total of 650 conventional orthopantomograms of German subjects aged 18-30 years were evaluated. The statistical evaluation of our results was based on a discriminant analysis. It was carried out with two classes defined by two age groups: < or = 21 years and > 21 years. The probability of correct classification was 69.7\% for males and 71.4\% for females. It can be concluded that an evaluation of the variables reviewed in this paper does not by itself yield sufficient data to determine with the accuracy required in criminal proceedings whether a person has attained 21 years of age. The additional radiographic examination of the medial clavicular epiphyseal cartilage is recommended.
