The age estimation by using teeth is widely used by many methods and of these methods is the Demirjian method which firstly was introduced in 1973 and used to estimate the age in children.

The sample was selected using a simple random sampling technique consisting of 500 orthopantograms, (243 boys and 257 girls) collected from Dental Hospital of University of Science and Technology, Esthetica, Almazin and Salah Dafallh’s dental centers. The developmental stages were assessed for each OPG in the left seven mandible permanent teeth and the EA was obtained using Demerjian method and then compared with the chronological age.
Result: The results showed that Demirjian method was not applicable on Sudanese population. It overestimated the age of female samples by about (0.13) years, and under estimated the age of male samples by about (0.46) years. Demirjian method was more reliable in females than males.
