In this study, complete dental prostheses with smile lines that coincided with the cervical margins of the anterior teeth were the most acceptable. Less exposure of the maxillary teeth when smiling corresponded with decreased attractiveness.
Objetivo: Analisar a rugosidade superficial dos cimentos ionoméricos resinosos Vitro Fil LC e Vitremer através de testes in vitro. Materiais e Métodos: Vinte corpos de prova foram utilizados e divididos em dois grupos: 1) Vitro Fil LC; 2) Vitremer. Após 24 horas, uma das faces de cada corpo de prova sofreu polimento mecânico e a outra serviu de controle positivo. Os materiais usados para a realização do polimento foram pontas siliconizadas para polimento Composite Fine, o material foi utilizado de acordo com as recomendações do fabricante. Terminado o polimento, os corpos de prova foram submetidos à análise de rugosidade superficial média (Ra), através da utilização de um Rugosímetro, expressa em micrômetros. Os resultados obtidos foram comparados pelo teste U de Mann-Whitney, após verificação da normalidade dos dados por meio da análise da simetria da curva de Gauss. O nível de significância adotado foi de 5% (α = 0,05). Os dados foram tabulados e analisados no programa estatístico BioEstat (versão 5.0, Belém-PA, Brasil). Resultados: Houve diferença significativa na Ra superficial entre a face polida e não polida, para os dois tipos de cimentos. Enquanto para o Vitro Fill LC foi verificada maior Ra superficial na face polida (p = 0,041), para o Vitremer foi observada na face não polida (p = 0,002). Para as faces polidas, o Vitremer apresentou Ra superficial significativamente menor (p = 0,001) do que o Vitro Fill LC. Conclusão: O cimento ionomérico resinoso Vitremer, quando polido, apresentou menor rugosidade superficial.
Aims
Evaluate the esthetic attractiveness of the Petit type facial masks of different colors among youngsters from public and private schools.
Materials and methods
Eight orthopedic facial masks of the Petit type, in different colors were evaluated. Images were obtained of the same patient, and were standardized with a program for changing images (Adobe Photoshop software from CS). The following colors were inserted in the masks: white, gray, green, yellow, blue, pink, orange and black. After acquisition, the images were printed on photographic paper and incorporated into a specific and personalized questionnaire. The questionnaire was distributed among children of both genders, in the age ranges from 7 to 8, and 9 to 10 years, at public and private schools (n = 200). For the scores attributed to each image, the Mann-Whitney test was used, and among groups, Spearman's correlation. The level of significance adopted was 5%.
Results
Only the scores attributed to the color brown presented significant difference between the schoolchildren from public and private schools. In a comparison between genders, the boys awarded better scores to the colors gray, blue and black, whereas the girls awarded better scores to the color pink. When comparing the age ranges examined there were no statistical differences.
Conclusion
The color of the Petit type of facial mask has an influence on the esthetic attractiveness to children from 7 to 10 years, and preference for certain colors is also influenced by gender and the type of school (public or private).
