Abstract:

Objective To investigate the esthetic perceptions of female maxillary central incisor and lateral incisor gingival margin asymmetries for orthodontic patients.Methods Female maxillary central incisor and lateral incisor gingival margin asymmetries models were set up. The distance from the gingival margin of the center incisor and lateral incisor to the incisor edge was set as 0.5 mm, 1.0 mm, 1.5 mm and 2.0 mm. A questionnaire was designed to investigate the esthetic perceptions of gingival margin asymmetries.Results In general, the most attractive smiles for the orthodontic patients were the ones without asymmetries or with a 0.5-1.0 mm asymmetry (P < 0.05). The patients could be initiated the difference by an asymmetry of 1.0 mm, and the asymmetries with 1.5-2.0 mm were not acceptable for anesthetics (P < 0.05). Conclusion The perceptions of anesthetic asymmetries in the gingival margin levels of the female maxillary central incisor and lateral incisor gingival margin were 1.0-1.5 mm, and this statics is somewhat clinically instructive.
