Is to find the accurate stranded cephalometric norms among the most significant sample of Iraqi adult's population and to see the racial variability between the Iraqi population cephalometric normative values and their counterparts of Caucasians population. A cephalometric analytic studies of Iraqi adults for period confined between 1988 to 2017 was conducted—twenty-seven studies from ninety-two. Collected studies were met the inclusion criteria. The selected studies have involved the published master theses, all of them exhibit numerical data for both genders of the Iraqi Arab population who have class I skeletal pattern with normal occlusion. Selection of 35 parameters took place, included most used skeletodental cephalometric measurements to be evaluated and compared. Statistical tests were applied to describe the means and SD, also to find out the statistical ethnic difference between the Iraqis Arab and Caucasians population. Study show standard norms of many cephalometric parameters exhibited a significant gender difference in Iraqi adults' individuals, with higher linear hard tissue measurements in males, while non-significant gender differences appeared in facial soft tissue profile. On the other hands, most of the elected cephalometric parameters showed statistically significant differences between the Iraqi Araband Caucasians compares.Generally, the Iraqis had smaller craniofacial dimensions, maxillary and mandibular skeletal retrusion, and more convex profile. Apparent sexual dimorphism in addition to significant ethnic difference requires the adoption of gender as well as ethnic specified standard norms during the cephalometric analysis of Iraqi Arab adult patients seeking orthodontic treatment, to reach an accurate diagnosis and treatment objectives.
