Multiple third molar development registration techniques exist. Therefore the aim of this study was to detect which third molar development registration technique was most promising to use as a tool for subadult age estimation. On a collection of 1199 panoramic radiographs the development of all present third molars was registered following nine different registration techniques [Gleiser, Hunt ( GH ); Haavikko ( HV ); Demirjian ( DM ); Raungpaka ( RA ); Gustafson, Koch ( GK ); Harris, Nortje ( HN ); Kullman ( KU ); Moorrees ( MO ); Cameriere ( CA )]. Regression models with age as response and the third molar registration as predictor were developed for each registration technique separately. The MO technique disclosed highest R 2 (F 51%, M 45%) and lowest root mean squared error (F 3.42 years; M 3.67 years) values, but differences with other techniques were small in magnitude. The amount of stages utilized in the explored staging techniques slightly influenced the age predictions.
