The aim of the study was to detect whether the W illems model, developed on a B elgian reference sample, can be used for age estimations in U nited A rab E mirates ( UAE ) children. Furthermore, it was verified that if added third molars development information in children provided more accurate age predictions. On 1900 panoramic radiographs, the development of left mandibular permanent teeth ( PT ) and third molars ( TM ) was registered according the D emirjian and the K ohler technique, respectively. The PT data were used to verify the W illems model and to develop a UAE model and to verify it. Multiple regression models with PT , TM , and PT + TM scores as independent and age as dependent factor were developed. Comparing the verified W illems‐ and the UAE model revealed differences in mean error of −0.01 year, mean absolute error of 0.01 year and root mean squared error of 0.90 year. Neglectable overall decrease in RMSE was detected combining PM and TM developmental information.
