Background
There are no norms for the McNamara analysis for Turkish adolescents.


Objective
To obtain cephalometric standards for the McNamara analysis for Turkish adolescents with balanced faces and Class I occlusions, and to compare the standards with published data.


Methods
The cephalometric radiographs of 116 children (83 female, 33 male) between 11 and 16 years of age with Turkish grandparents and Class I occlusion, well-aligned upper and lower dental arches, no anterior and/or posterior crossbites and normal dentofacial structures were used. The eight linear and two angular measurements in the McNamara analysis were measured on images of the scanned radiographs. Measurements of the male and female subjects were compared with each other and with published norms for North American adolescents and adults.


Results
The Co-Gn, Co-A, ANS-Me and Ui-A were larger in the male subjects. Comparisons between the present study and McNamara’s original study revealed that Anatolian Turkish adolescents, particularly girls, have smaller midfacial and mandibular lengths and longer and more retrusive faces than North American adolescents and adults.


Conclusions
The small, but statistically significant, gender differences in mandibular and midfacial lengths and lower anterior face height may not be clinically significant. A single set of Turkish norms for the McNamara analysis may be appropriate.
