Abstract
AimThe aim of this study was to evaluate the influence of education on the perception of female college students on the effect of lip position and gingival display upon smiling and esthetics.MethodsA photograph of a smiling subject was altered to show varying degrees of gingival display. Female students, who were studying in different colleges, assessed a total of five images, using a numerical rating scale.ResultsA total of 440 college students from eight educational faculties (dentistry, dental assistants, medicine, medical technology, nursing, science, arts, and pharmacology) participated in this study. There was no difference found between students’ ratings of the altered images (P<0.05). The perception of a gummy smile was found to be similar among the participants. There was agreement between all participants that 2 mm of gingival display was the most attractive smile, while a 4 mm covering of the teeth by the upper lip was the least attractive.ConclusionEducational influence did not have an effect of the perception of a gummy smile.
