A concave profile were presented in (5.9%)students (5.54%) males and (6.24%) females), The malocclusion were presented (73.05%) students (73.46%) malesand (72.64%) females, According to the Dental health component of index of the orthodontic treatment subjectswith no need for treatment were about 44.11% , the subjects who need little treatment were about 26.82%, 13.06% ofthe subjects who need moderate treatment, 10.03% great treatment need and about 5.98% very greatly treatmentneed.Conclusions: Orthodontic treatment need according to IOTN shows that there was no significant difference betweenmales and females in the malocclusion, Facial profile and treatment need
