Abstract

Cephalometric normals of Mc Namara’s analysis were studied in a sample of 60 adult Saudian subjects (30 males and 30 females), who satisfied the criteria of pleasing face. The age was ranged from 20 to 25 years. Cephalometric radiographs were taken and traced for all subjects. Students t-test was used for data analysis. Eleven skeletal and dental cephalometric variables were studied. The results showed that, there were statistically significant gender differences in four variables. Mandibular length, midface length, lower anterior facial height and mandibular plane angle were higher in males than females. There were a significant racial differences in nine variables. Where Saudian sample had more retrusive maxilla and mandible, more vertical mandibular growth pattern, and more dental protrusion.
