The purpose of this article was to determine the amount of cranio-facial asymmetry
in normal subject before the analysis of the cranio-facial asymmetry as the result of
internal derangement in T.M.J. dysfunction. The author has conducted analysis using
Cephalometric P-A reviews of 54 males and 51 females. Following the Grayson's
method of measurement, the standard value of cranio-facial asymmetry in normal
subject was obtained.
The following results were obtained:
1. Compared with right and left width, asymmetry could be identified in normal
subject, although the degree of the difference appears to be small,
2. In male, asymmetric value of contact point of the upper central incisors is 0.76¡¾
0.84§®, that of the lower central incisors is 0,87¡¾1.06§®, and that of center of genial
tubercle is 0.87¡¾1.06§®.
In female, asymmetric value of contact point of the upper central incisors is 1.03¡¾
1.29§®, that of lower incisors is 1.11¡¾1.18§®, and that of center of genial tubercle is 1.45
¡¾2.15§®.
3. Cranio-facial saymmetry in female is somewhat greater than that of male.
