“…This method was endorsed by several investigators 4,8,9,16,19,23 because of its simplicity and speed, being easily understood by the examiners and widespread in literature. In this study the VAS scale was characterized as a 100 mm line, where zero represented that profiles contained in the same sheet were the same and in the opposite extreme, that they were very different.…”

Objective: Evaluate the facial profile changes of orthodontic treatment with extraction of two upper first premolars, from the perspective of orthodontists, dentists and lay people. Methods: Facial profiles of radiographs taken before and after treatment of 70 patients with Class II, division 1 malocclusion were traced. The silhouettes of the 70 patients were randomly assembled in an album with, being two profiles on each sheet of the same patient. Then, 30 orthodontists, 30 dentists and 30 lay people chose the more esthetic facial profile (A or B), and the amount of change they perceived between the two profiles before and after treatment, according to a visual analog scale (VAS). Results: The results revealed that 83 examiners preferred the posttreatment profiles, and only three dentists and four lay people chose the profiles pre-treatment more frequently. Thus, the orthodontists often chose the profiles after treatment, followed by dentists, with no statistically significant differences found between dentists and lay people. There were significant differences within groups in the preference of pre-and post-treatment profile. Furthermore, the three groups of evaluators indicated that pre and post-treatment profiles did not differ substantially. Conclusions:The treatment of Class II, division 1 malocclusion with extraction of two first premolars has a positive effect on facial profile esthetics. Objetivo: avaliar as alterações do perfil facial decorrentes do tratamento ortodôntico com extrações de dois primeiros pré--molares superiores, sob a óptica de ortodontistas, cirurgiões-dentistas e leigos. Métodos: foram traçados os perfis faciais das telerradiografias pré-e pós-tratamento de 70 pacientes com má oclusão de Classe II, divisão 1, e foi montado um álbum com as silhuetas dos 70 pacientes, de forma aleatória, sendo dois perfis em cada folha do mesmo paciente. A seguir, 30 ortodontistas, 30 cirurgiões-dentistas e 30 leigos escolheram o perfil facial mais estético (A ou B), e a quantidade de alteração que percebiam entre os dois perfis pré-e pós-tratamento, de acordo com a escala visual analógica (EVA). Resultados: os resultados revelaram que 83 examinadores preferiram o perfil pós-tratamento, sendo que somente três cirurgiões-dentistas e quatro leigos escolheram com maior frequência os perfis pré-tratamento. Assim, os ortodontistas escolheram mais frequentemente os perfis pós-tratamento, seguidos pelos cirurgiões-dentistas, sem diferença estatisticamente significativa entre cirurgiões-dentistas e leigos. Houve diferença estatisticamente significativa intragrupos na preferência do perfil pré-e pós-tratamento. Além disso, os três grupos de avaliadores indicaram que os perfis pré-e pós-tratamento não diferiram substancialmente. Conclusões: o tratamento da má oclusão de Classe II, divisão 1, com extração de dois primeiros pré-molares produziu um efeito positivo na estética do perfil facial.Palavras-chave: Extração dentária.

“…Este método se utilizó para cuantifi car las emociones sobre el impacto estético de la inclinación del incisivo central superior en la sonrisa, siendo una herramienta utilizada en varias investigaciones debido a su simplicidad, evitando el sesgo hacia valores preferidos que se encuentran con escalas numéricas o de intervalo, permitiendo un mejor análisis de la cantidad y permitiendo examinar mejor la importancia de las diferencias en las distribuciones (2,14,15). En el presente estudio se realizó una valoración cuantitativa donde se encontraron que la percepción en pacientes presentó un valor de 7,17 cm ± 1,56 cm; mientras que en los estudiantes se obtuvo una valoración 6,74 cm ± 1,32.…”

“…Presentando dichas fotografías algunos distractores como: el cabello, los ojos, la nariz, las cejas, el tono de piel etc., lo que pudo afectar la evaluación. Sin embargo, otros estudios (14,16) incluyen también la presencia de dichos distractores para obtener información verdadera con respecto a la evaluación del atractivo facial. Ghaleb y col. (2) y Cao y col. (5) utilizaron fotografías de perfi l similares a las nuestras siendo éstas más importantes, que sólo el atractivo de la condición dental.…”

“…In a study by Pithon et al (5), the same images were reviewed by laypeople of three age groups (15)(16)(17)(18)(19)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44), and 65-74 years, respectively). The results of that study showed that older people had more difficultly perceiving black spaces than the younger subjects.…”

“…A visual analog scale (VAS) was used to assess esthetic perception by students and laypeople. The VAS is a simple and practical method to evaluate esthetic preferences on a scale of 0 to 10, where 0 = least attractive; 5 = attractive; and 10 = most attractive (12,(18)(19)(20)(21)(22)(23)(24).…”

Evaluation of black spaces between maxillary central incisors by dentistry students and laypeople

This study aimed to compare the perception of smile esthetics and alterations among dentistry degree students and laypeople to identify differences in the esthetic perception of black spaces between the maxillary central incisors among Turkish laypeople and students in different study years. Photographs altered to include black spaces of various sizes at the midline were evaluated by 208 dentistry students in years 1-5 and 45 Turkish laypeople. Perceptional differences in different photographs were statistically significant. The students in years 2-5 were more aware of differences between photographs than year 1 students and laypeople. The proportion of participants who decided the most attractive photograph as A was highest among 3rd year students, followed by 5th year students. However, the proportion of students agreeing on the least attractive image was highest among 4th year students, followed by 3rd year students. Photographs A and H were selected as the most and least attractive, respectively, by all participants. The esthetic perception of 1st and 2nd year dentistry students was very different from that of laypeople. To increase esthetic perception among dentistry students, specific lessons with clinical photography should be included in dental education.
