Objective: To evaluate the degree of perception of laypersons, dental professionals, and dental students regarding dental esthetics in cases with mandibular central incisor extraction. Materials and Methods: Using a smile photograph of a person with normal occlusion and all teeth, modifications were made to reflect the extraction of a mandibular incisor of various compositions and sizes. For this purpose a program specifically for image manipulation (Adobe Photoshop CS3, Adobe Systems Inc) was used. After manipulation the images were printed on photographic paper, attached to a questionnaire and distributed to laypersons, dental professionals, and dental students (n 5 90) to evaluate the degree of perception and esthetic using a scale of attractiveness, where 0 5 hardly attractive, 5 5 attractive, and 10 5 very attractive. The differences between examiners were checked by the Mann-Whitney test. All the statistics were performed with a confidence level of 95%. Results: The results demonstrated the skill of the dental professionals and dental students in perceiving the difference between cases of normal occlusion and cases where an incisor was lacking (P , .05). The photograph in which the lateral incisors were shown to be larger than the central incisor was the one that obtained the highest value among the cases of extraction in all groups of evaluators. Conclusions: It can be concluded that dental professionals and dental students are more skillful at identifying deviation from normality. In addition, central incisor extraction should always be discarded when there are other treatment options available. (Angle Orthod. 2012;82:732-738.)

According to aesthetic parameters, the presence of the gingiva is important in the composition of the smile, however, only when exposed to small extent.

It could be concluded that black spaces occurring after mandibular incisor extraction had a negative repercussion on dental esthetics for the dentist, the dental student, and the layperson.

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).
