Abstract

Introduction: Dentists have shown interest in learning new techniques to create more attractive smiles, but with little concern for understanding the reasons why the patient is dissatisfied.

Objective: To evaluate the aesthetic perception of laypersons in dentistry in comparison with general practitioner dentists and periodontists regarding the gingival smile, and to compare this aesthetic perception between the male and female genders.

Methodology: A photograph of a standard smile was taken and was digitally modified to create the periodontal conditions of a gingival smile from 0.5 mm to 2.5 mm. The photographs were judged by 150 individuals (25-65 years of age), 81 female and 69 male, divided into three groups: 50 laypersons, 50 general practitioners and 50 periodontists. The evaluation was performed using a visual analog scale. The statistical evaluation tests used were the Pearson Chi squared test, Student's t-test, ANOVA and Newman-keuls.

Result: The aesthetic perceptions among the professionals are similar, and they observe more subtle changes in the aesthetics of the smile than the laypersons observe. The general practitioners and periodontists were similarly sensitive to changes generated in the gingival smile when these reached 1.5 mm, while laypersons only perceived them when these changes reached 2.5 mm. There was no significant difference in the aesthetic perception of male and female evaluators in any of the groups.

Conclusion: The aesthetic perception of the gingival smile between general practitioner dentists and periodontists was similar, and dental professionals were more demanding than the layperson. There was no difference between female and male aesthetic perceptions.

Resumo

Introdução: Cirurgiões-dentistas têm mostrado interesse em conhecer novos meios para a construção de sorrisos mais atraentes, porém com pouca preocupação em entender os motivos pelos quais o paciente está insatisfeito.

Objetivo: Avaliar a percepção estética de pessoas leigas em odontologia em comparação com dentistas clínicos gerais e periodontistas quanto ao sorriso gengivoso, e comparar esta percepção estética do gênero masculino e feminino.

Metodologia: Foi realizada fotografia de um sorriso padrão e modificada digitalmente para criar as condições periodontais de sorriso gengivoso de 0,5mm até 2,5mm. As fotografias foram avaliadas por 150 indivíduos (25-65 anos), 81 do gênero feminino e 69 do masculino, divididos em três grupos: 50 leigos, 50 clínicos gerais e 50 periodontistas. A avaliação foi realizada por escala analógica visual. Os testes de avaliação estatística utilizados foram Quiquadrado de Person, t de Student, ANOVA e Newman-keuls.

Resultado: As percepções estéticas entre os profissionais são semelhantes, e percebem mudanças na estética do sorriso mais sutis que leigos. Os clínicos gerais e os periodontistas foram sensíveis de forma semelhante às mudanças geradas no sorriso gengivoso quando estas chegaram a 1,5 mm, enquanto que os leigos só perceberam quando estas modificações chegaram a 2,5 mm. Em todos os grupos não houve diferença significativa da percepção estética de avaliadores do gênero masculino e feminino.

Conclusão: A percepção estética do sorriso gengivoso entre dentistas clínicos gerais e periodontistas foi semelhante, e os profissionais de odontologia foram mais exigentes do que os leigos. Não houve diferença na percepção estética feminina e masculina.
