Abstract | AIMS: To establish cephalometric norms for Chinese using modified Björk’s analysis (1947) and
compare them with those of Caucasians.
MATERIALS AND METHOD: Lateral cephalometric radiographs taken in natural head posture of a
random sample of 200 male and 205 female 12-year-old southern Chinese together with 43 male and
43 female 12-year-old British Caucasians in Hong Kong. The radiographs were digitised twice with
the CASSOS program.
RESULTS: In males, the inter-incisal angle, A,B on OP and SN length were significantly larger in
Caucasians than in Chinese. On the other hand, the SNA, SNB, SN/MnPl, SN/MxPl, SN/Ui,
Ui/MxPl, Li-APo, upper face height and upper and lower lip to E line were significantly larger in
Chinese males than in Caucasian males. For females, NSBA, ANB, inter-incisal angle, A,B on OP
and SN length were significantly larger in Caucasian than in Chinese. On the contrary, SNA, SNB,
SNPg, SN/MnPl, SN/MxPl, SN/Ui, Ui/MxPl, Li-APo, upper and lower face height, and upper and
lower lip to E line were significantly larger in Chinese females than in Caucasian females.
CONCLUSIONS: There are significant differences between Caucasians and Chinese when using the
modified Björk’s analysis. |
