Cephalometric norms for the Vietnamese population

Objectives: This study aims to define some oro-facial indexes and measurement of Vietnamese people aged 18-25 on cephalometric films using Steiner analysis to establish specific data resources in order to apply in treatment, esthetics, forensic recognition, anthropometrics and labour safety products. Methods: Comparative study. Results: To compare with Caucasian people regarding to skeletal-dental relationship, Vietnamese are likely to have more protrusive maxilla and mandibles. This indicates difference in oro-facial structure between Vietnamese and Caucasian people. Conclusion: Standards of one racial group could not be used without modification for other racial groups, and each different racial group would have to be treated according to its individual characteristics.
