Sažetak
The aim of the study was to apply different dental age estimation methods such as the Demirijan's, Williems', Moorree's and Cameriere's method to Kosovar population aged 6-24 years in order to compare the accuracy of these methods, and to correlate chronological age with dental age. Also, the aim was to develop a specific maturity chart and formula to estimate age in a sample of children from Kosovo. The sample of orthopantomographs was selected from 1952 healthy people aged 6 to 24 years old. The radiographs taken from the files of a radiography unit of the University Dentistry Clinical Center of Kosovo in Pristina were retrospectively reviewed. The radiographs from patients who did not have all seven left mandibular teeth, blurry images, were not included in this study. Chronological age has been calculated as the difference between the date when panoramic radiographs were taken and the birth date, with age groups based on one-year increments. Radiographs were collected by one examiner and rated after three months. Dental maturity was calculated using the Demirijan's, Willems' Moorrees' and Cameriere's regression formula. It has been observed that mineralization was completed after the age of 16 in a large majority of individuals. Intra-class correlation coefficients were 0.858 for intra-rater agreement. For a majority of tested methods, a statistically significant difference was found between chronological age and dental age. In males, the most accurate methods were those using four teeth Dem76IN2. In females, dental age was the most accurate for the Willems method. The mean absolute difference between DA and CA were between 0.74 years for the Willems, 0.77 for Dem73, 0.83 for Cameriere. The results showed that only I3M statistically significantly contributed to discriminating adults and minors. ROC analysis showed that the cut-off value of I3M < 0.08 was the best in discriminating adults and minors. The mineralization of the mandibular teeth was ahead in females in most stages. The Willems method was the most accurate method for estimating dental age if all seven mandibular teeth were available for analysis. Therefore, these methods were recommended for age estimation of Kosovar children. Also, this research has found the effectiveness of I3M in estimating 18 years of age in Kosovar children and adolescents.
