摘要
Abstract
Objective To examine the influence of the smile line on the smile esthetic perceptions of orthodontists and laypeople, using a visual analog scale questionnaire. Methods ①One photogragh of a smiling young female, displaying first molar to first molar, was constructed. ②The smile line height was modified digitally in 2.0mm increments, from -4.0mm to 6.0mm. ③Using a visual analog scale (VAS), 30 orthodontists and 50 laypeople rated the attractiveness of the six smiles with different smile line. Results ①There were significant differences in the median esthetic scores for both orthodontists and laypeople.(orthodontists:χ2=109.596,P<0.01;laypeople:χ2=151.230,P<0.01).②Both orthodontists and laypeople considered smiles with smile line height within the range of -4.0mm to 2.0mm to be pleasant, smiles with smile line height larger than 4.0mm to be unpleasant.③Orthodontists rated the smile with smile line height of 0 mm as the most attractiveness, laypeolple rate the smile with smile line height of -2.0 mm as the most attractiveness. Conclusion The smile line height had influence on smile esthetics. Both orthodontists and laypeople shared the same opinion that smiles with gingival display less than 2.0mm were pleasant, while smiles with gingival display more than 4.0mm were unpleasant. orthodontists considered that the smile revealing 100% of the maxillary central incisors' crown height without gingival display to be most attractive, while laypeople judged the smile with upper lip coverage 2.0 mm of the maxillary central incisors' crown as most attractiveness. In clinical practice, orthodontists should enhance communication with patients to obtain the best aesthetic effect关键词
