A comparative study of southern Chinese and British Caucasian cephalometric standards.

A comprehensive cephalometric comparison between unselected Chinese and Caucasian 12-year-old male children in natural head posture finds the intracranial reference planes to slope down more caudally in the Chinese. By superimposing on true vertical, the degree of prognathism in the Chinese becomes apparent. Significant intergroup differences are highlighted for both selected dentoskeletal and soft tissue profile variables.
