Abstract

Abstract: Introduction: Patients’ demand for dentogingival aesthetics has increased significantly in recent years, and this is a complex concept due to numerous factors involved in obtaining patient/professional satisfaction. Some dentogingival features may alter smile harmony, such as excessive gingival display.

Objective: To evaluate whether the presence of gingival display has a negative influence on the perception of dentogingival aesthetics.

Material and method: 180 individuals (60 dentists, 60 dental students, and 60 patients) evaluated images of volunteer smiles. These images were digitally altered by the Adobe Photoshop™ software, creating different situations of gingival display (4 mm, 2 mm, 0 mm, -2 mm, -4 mm), and graded by the evaluators with the following scores: (01) very pleasant smile, (02) pleasant smile, and 03) unpleasant smile. The scores assigned were analyzed using ANOVA (α=0.05).

Result: Gingival displays between 0 and 2 mm were considered aesthetically pleasing. Changes of -4 and +4 mm were defined as the most disharmonious smiles. The 0-mm female smile was considered the most harmonious for dentists (1.51) and dental students (1.77), by Student's t test (p<0.05). In the opinion of patients, the smile of +2 mm was considered the most aesthetic. In the image evaluations of men, the 0-mm smile was considered the most aesthetic (p <0.05) for dentists (1.85) and dental students (1.62). The patients considered +2 mm of gingival display the most harmonious smile.

Conclusion: The aesthetic perception of dental students and dentists was different when compared to the group of patients.

Resumo

Resumo: Introdução: A procura dos pacientes pela estética dentogengival tem aumentado significativamente nos últimos anos, sendo um conceito complexo devido aos inúmeros fatores envolvidos para a obtenção da satisfação paciente/profissional. Algumas características dentogengivais podem alterar a harmonia do sorriso como por exemplo o excesso de exposição gengival.

Objetivo: Avaliar se a presença da exposição gengival tem uma influência negativa na percepção da estética dentogengival.

Material e método: 180 indivíduos (60 dentistas, 60 acadêmicos de odontologia e 60 pacientes) avaliaram imagens de sorrisos de voluntários. Essas imagens foram alteradas digitalmente pelo software Adobe Photoshop™, criando diferentes situações de exposições gengivais (4 mm, 2 mm, 0 mm, -2 mm, -4 mm), e classificados pelos avaliadores através dos escores: (01) sorriso muito agradável, (02) agradável e (03) desagradável. Os escores atribuídos foram analisados por meio da ANOVA (α=0,05).

Resultado: Exposições gengivais entre 0 e 2 mm foram consideradas esteticamente agradáveis. Alterações de -4 e +4 mm foram definidas como as mais desarmônicas. O sorriso de 0 mm no sexo feminino foi considerado mais harmônico para os dentistas (1,51) e estudantes de odontologia (1,77), pelo teste t de Student (p<0.05). Na opinião dos pacientes o sorriso de +2 mm foi considerado o mais estético. Na avaliação das imagens do sexo masculino, o sorriso de 0 mm foi considerado o mais estético (p<0,05), para dentistas (1,85) e estudantes de odontologia (1,62). Os pacientes consideraram +2 mm de exposição gengival como o sorriso mais harmônico.

Conclusão: A percepção estética de estudantes de odontologia e cirurgiões dentistas foram diferentes quando comparado ao grupo dos pacientes.
