A simple photographic setup was established to produce standardized life-sized black and white prints of Southern Chinese adults. Facial soft tissue profile analysis was performed on 28 men and 31 women aged 19 to 30, dentate Chinese, having class I occlusion and originating from Guangdong province. The facial profile values studied included the profile convexity, the interlabial contour, the nasolabial contour, the columella and upper lip inclination angles to the true horizontal, and the relative positions of upper and lower lips from the Esthetic plane. Data obtained were compared with those from previous Caucasian studies and other accepted empirical values. The lower third of the face presented the greatest ethnic difference: the interlabial contour was more convex and the upper and lower lips were more protrusive among the Southern Chinese. The widely-used standard of a right-angled nasolabial contour proved to be applicable among the Southern Chinese adult males. However, a more obtuse nasolabial angle, almost 100 degrees, occurred among the women.
