The accuracy of 15 _ 25 years age estimation using panoramic radiograph with thevissen method in Indonesia

[摘要] Age estimation is important for individual identification. Root development of third molars occurs at age 15-25 years. This study was conducted to determine the accuracy of age estimation using the Thevissen method in Indonesia. The Thevissen method was applied to 100 panoramic radiographs of both male and female subjects. Reliability was tested by the Dahlberg formula and Cohen's Kappa test, and the significance measurement was tested by the paired t-test and the Wilcoxon test. The deviation of estimated age was then calculated. The deviation of age estimation was ±3.050 years and ±2.067 for male and female subjects, respectively. The deviation of age estimation of female subjects was less than male subject. Age estimation with the Thevissen method is preferred for age 15-22 years.
