To compare different standpoints towards the anterior teeth aesthetics among people in different generation, and set up a reference for the Esthetic restoration.

A electronic questionnaire with pictures and visual analog scale, which includes some variable common parameters for anterior teeth aesthetics, such as the width proportion of upper anterior teeth, the width/length proportion of upper anterior teeth, the upper lip line position in smile, the buccal space size and the angle of inclination of clinical crown of upper incisors, was designed in this research.

The results indicate a significant difference between the dentists′ and layman′s standpoints in upper anterior teeth width proportions (P<0.05) , upper lip line position in smile (P<0.05) and the angles of inclination of clinical crown of upper anterior teeth (P<0.05) in contrast to the size of buccal space (P= 0.176) and the upper incisors width/length proportion (P= 0.192) . However, no significantly statistical differences were found among different academic careers, income, living place, official rank or different working lifetime in layman′ and dentists′ standpoints toward the anterior teeth aesthetics (P>0.05) .

Significant differences were concluded between dentists and layman′s standpoint toward such common parameters of the anterior teeth aesthetics as the standpoints in upper anterior teeth width proportions, upper lip line position in smile, the angles of inclination of clinical crown of upper anterior teeth. Therefore, we should improve communication between doctors and patients, and obtain the best results of the anterior dental restoration by carefully scrutinizing differences in the above three aspects of the aesthetic standpoints.
