“…5,6 During interpersonal interaction, it is most common for individuals to focus on the other person's eyes and mouth and give less attention to other facial characteristics. 7 The teeth are considered the most important components in the facial architecture, 8 and a harmonious smile plays an important role in establishing physical and facial beauty. 9 Attractiveness causes positive emotional reactions in the observer, creating desires to establish affective/ romantic relationships.…”

; Rogé rio Lacerda dos Santos d ABSTRACT Objective: To evaluate the extent to which different types of malocclusion influence the development of affective/romantic relationships among young adults of both sexes. Materials and Methods: A cross-sectional study was conducted with 360 men and women ranging in age from 18 years to 25 years. Criteria for exclusion from the sample were the following: participants could not be married, visually impaired, or students of a higher education course in the area of health. In this study, images of young adult men and women in the same age range as that of the evaluators were used. These images were manipulated to create different types of malocclusion: diastema, open bite, crowding, gingival (or gummy) smile, little exposure of teeth. Six groups of images containing six images each were formed and consisted of two experimental images (digitally manipulated) and four control images. These images were provided to the participants, who evaluated them by means of a questionnaire and a visual analog scale. The Kruskal-Wallis, Mann-Whitney, chi-square, and Fisher exact tests were used for data analysis. Results: All malocclusions had a negative impact on acceptance by the evaluators for the purposes of affective/romantic relationships, with crowding being the type of malocclusion that led to the highest level of rejection (P , .01). Conclusion: Malocclusions have a negative influence on the development of affective/romantic relationships among young adults. Individuals with good occlusion are seen in a more positive light, from the perspective of affective life. (Angle Orthod. 2016;86:638-643.)

“…[9][10][11][12][23][24][25][26] In the literature, digitally altered images have often been created from a single image of the same patient to obtain a variety of sizes of the buccal corridor. [9][10][11][12][23][24][25][26] However, studies on the buccal corridor with nonmanipulated photographs 13,27 have failed to report a correlation between the buccal corridor and smile attractiveness. Janson 6 recently reviewed previous articles on this matter and concluded that images of actual patients are more acceptable SMILE ATTRACTIONS than digitally altered smiles.…”

“…9,10 An equal number of male and female evaluators were used. [10][11][12] According to the method of McNamara et al, 13 selected images were printed on evaluation sheets at a fixed width of 100 mm along with a 100-mm visual analogue scale (VAS) (Figure 2), which was used by the students to evaluate the attractiveness of the images. Student evaluations were measured in millimeters from the left end of the 100-mm bar using a digital caliper (NTD12-15CX; Mitutoyo, Kawasaki, Japan).…”

Objective: To identify appropriate dimensional items in objective diagnostic analysis for attractiveness of frontal posed smile in Japanese female patients by comparing with the result of human judgments. Materials and Methods: Photographs of frontal posed smiles of 100 Japanese females after orthodontic treatment were evaluated by 20 dental students (10 males and 10 females) using a visual analogue scale (VAS). The photographs were ranked based on the VAS evaluations and the 25 photographs with the highest evaluations were selected as group A, and the 25 photos with the lowest evaluations were designated group B. Then 12 dimensional items of objective analysis selected from a literature review were measured. Means and standard deviations for measurements of the dimensional items were compared between the groups using the unpaired t-test with a significance level of P , .05. Results: Mean values were significantly smaller in group A than in group B for interlabial gap, intervermilion distance, maxillary gingival display, maximum incisor exposure, and lower lip to incisor (P , .05). Conclusions: Significant differences were observed only in the vertical dimension, not in the transverse dimension. Five of the 12 objective diagnostic items were correlated with human judgments of the attractiveness of frontal posed smile in Japanese females after orthodontic treatment.

“…La importancia de una sonrisa atractiva ha variado con el pasar de los años y recientemente la evaluación de esta ha despertado un gran interés por parte de los clínicos, llevándolos a evaluar variables como el corredor bucal y la coincidencia de la línea media dental, a pesar de la poca evidencia científica existente. [1][2][3][4][5][6][7][8] La evaluación del perfil facial en el diagnóstico ortodóncico ha tenido hasta ahora mayor relevancia que la evaluación de la sonrisa. 8 Así por ejemplo, en el aniversario número 100 de la Sociedad Americana de Ortodoncia el logo fue "Ortodoncia 100 años de Sonrisa" y si se busca en Medline desde 1967 hasta 2008 con palabras clave como "Orthodontics" y "Smile" se encuentran solo 23 referencias; por el contrario, si se busca "Orthodontics" y "Facial profile" se hallan 153 artículos.…”

RESUMENObjetivo: evaluar la percepción de la sonrisa desde la perspectiva de los ortodoncistas y de las personas sin conocimientos de ortodoncia. Materiales y métodos: se realizó un estudio de corte transversal para lo cual se diligenciaron 207 cuestionarios de conocimientos y percepción de la sonrisa, por 43 ortodoncistas y estudiantes de la Especialización en Ortodoncia de la Universidad Santo Tomás (grupo 1) y 164 personas sin conocimientos de ortodoncia (grupo 2). Las variables de salida fueron la percepción de alteraciones en la línea media y en el corredor bucal; las variables explicatorias fueron la edad, el sexo y la condición socioeconómica. La información se describió mediante promedios y desviación estándar, y frecuencias y porcentajes según la naturaleza de las variables. Se aplicó la prueba de Chi cuadrado y se consideró un valor de p<0,05 como estadísticamente significativo.Resultados: la línea media con desviación de 1 mm y la centrada fueron las que más agradaron a hombres y mujeres, en los dos grupos de estudio. Al determinar la sonrisa menos agradable, los grupos coincidieron en que fue la de mayor desviación (4 mm). Se encontró asociación entre el conocimiento y la percepción de la desviación de la línea media en 2 mm (p=0,044) y 4 mm (p=0,000). Sonrisas con un corredor bucal amplio, medio y medio amplio son percibidas como menos agradables para ambos sexos, la totalidad de las mujeres valoró el corredor bucal amplio como menos agradable.Conclusión: no se presentó una diferencia estadísticamente significativa en la percepción de las características de la sonrisa entre personas sin y con conocimientos de ortodoncia [Torres MC, Barreto K, Polanco AM, Peña LL, Álvarez CM. Evaluación de la percepción de la sonrisa en personas con y sin conocimientos en ortodoncia. Ustasalud. 2014; 13: 32 -39] Palabras clave: sonrisa, ortodoncia, percepción. PERCEPTION OF THE SMILE ON PEOPLE WITH AND WITHOUT KNOWLEDGE IN ORTHODONTICS ABSTRACTObjective: to assess the perception of the smile from the perspective of orthodontists and people without knowledge in orthodontics. Methods: a cross-sectional study was carried out. Two hundred and seven questionnaires about knowledge and perception of the smile were completed by 43 orthodontists and students of the Especialización en Ortodoncia at the Universidad Santo Tomás (group 1) and 164 people with no knowledge in orthodontics (group 2). The dependent variables were the perception of alterations in the midline and the buccal corridor; the explanatory variables were age, sex and socioeconomic status. The information was described by means and standard deviations, frequencies and percentages depending on the nature of the variables. Chi-square test was applied and a p value <0.05 was considered statistically significant.Results: the midline deviation of 1 mm and centered were chosen for men and women as the most pleased the two study groups. In determining the least pleasant smile, the groups agreed that the least pleasant smile was when it presented the largest deviation...

Abstract: The hypothesis was rejected. Both the orthodontists and dental students preferred broader smiles to medium or narrow smiles.
