To assess the chronologic age based on the mineralized stages of mandibular third molar development following the stages of eruption using modified demirjian’s method.
To evaluate the stages of eruption and to derive a formula for age estimation.
Panoramic radiographs from 200 Chennai populations with unknown age and gender were selected for the study. The investigated radiographs were collected from the records of SRM dental college. Radiographs with any pathology, facial deformities, congenital deformities, trauma, magnification and distortion were excluded.
There was no statically difference between interobserver and intraobserver reliability. Stastical difference exists between genders, in which male showed earlier eruption than females.
Radiographic is cheaper and routinely used method of age identification. hence sound knowledge is necessary to choose the appropriate methods and to identify the stages of mineralization so that its application is extended in medico legal cases.
