Aims: The aims of this study were to introduce cephalometric norms for Qatari females and compare the result with previous published reports.

Material and method: The sample consisted of 57 cephalographs with age range 18 to 25 years old. All subjects satisfied the criteria of selection. Cephalometric measurements of Qatari females were then compared with Eastman Standard norms and Arabs studies as well as reports conducted among Oriental and Black races.

Results: The result indicates that Qatari females presented with higher mean values of sagittal and vertical relationship compared to Caucasian cephalometric norms. In terms of dental variables proclined upper and lower incisors in relation to their dental bases, and a reduction in inter-incisal angle. The soft tissue variables indicate that the lips were slightly protrusive in relation to Rickett’s esthetic line, and the nasolabial angle was less obtuse. The bimaxillary proclination and protrusion of the upper and lower incisors were existed in all Arab populations as well as in Black and Oriental races whereas the Caucasian had retrusive dentition.

Conclusion: Due to limitation of the present study, it is difficult to draw a solid conclusion due to small sample size.  Hence, large sample size is recommended for both sexes in order to establish cephalometric norms which will be of great help not only to the orthodontist but also to the oral and maxillofacial surgeon as well as the pedodontist.
