Cephalometric evaluation of Iranian children and its comparison with Tweed's and Steiner's standards.

The craniofacial characteristics of Iranian children were investigated in order to formulate cephalometric norms using Tweed and Steiner angular and linear measurements. The sixty-seven Iranian children studied included thirty-five girls and an average of 12.5 years and thirty-two boys with an average age of 12.4 years. The subjects were chosen on the basis of ethnic background (geographic area, religion, and language), good health, and normal occlusion. Thirty-two variables were tabulated, and statistical tests were employed.
