Objective To investigate the smile esthetic elements of Chinese Han-nationality female based on high definition (HD) digital camera with computer-image measuring technique.Methods HD digital camera was used to capture spontaneous smile process combined with computer-image measuring technique to establish the analysis method of smile.Ninety-nine Han-nationality female with normal gingiva,aged from 20 to 30 years were recruited.The lip-incisor edge distance,gingival display were measured.The data was statistically analyzed.Results A standard and objective method to analyze spontaneous smile was established.Forty-three percent(43/99) of the subjects studied were classified as having a high smile and average smile respectively,13％ (13/99) as having a low smile. Gingival display accounted for (1.34 ±0.98) mm in high smile type.Conclusions Average smile and high smile type were most common in the Chinese Han-nationality female studied.
