“…These results are comparable to those of other publications [29,39]. A coincident midline is the most prevalent presentation in nature and must be respected in prosthetic dental treatment in order to ensure an aesthetic outcome [33,40]. Silva et al [7] found the threshold for perceiving a deviation of the maxillary interincisal midline with respect to the facial midline to be 2 mm, in coincidence with the observations of other authors [16,18].…”

Background: A number of reference patterns such as the interincisal line, curve of the upper lip, width of the smile or shape of the teeth have been studied in different populations. Determining the frequency of different smile aesthetic parameters in a European Caucasian population and exploring possible gender differences is important in order to obtain predictable treatment outcomes. Methods: Photographs were obtained under resting and forced smiling conditions in 140 individuals (70 males and 70 females) with a mean age of 20.1 ± 4.3 years. Different variables were recorded, including the position of the maxillary interincisal midline in relation to the facial midline, the arc and width of the smile, and the shape of the teeth. The data were processed using the SPSS version 15.0 statistical package, with application of the chi-squared test and a confidence level of 95%. The statistical power was 80%, and the level of significance 5% (α = 0.05). Results: A total of 94.3% of the sample presented a maxillary interincisal midline coinciding with the facial midline, and 80% had a consonant smile line. The curve of the upper lip was upwards in 47.1% of the cases, followed by a straight curve in 41.4%. Most of the subjects (84.3%) presented a medium smile line with tooth exposure to the second premolar (61.4%). There were no significant differences between males and females. Conclusions: The integration of aesthetic criteria is needed in order to guarantee satisfactory and predictable dental treatment outcomes. There were no statistically significant differences between males and females. The maxillary interincisal midline coincided with the facial midline, with a consonant smile arc and a medium smile line, upward lip curve and oval tooth shape.

“…In the study of Armalaite et al [12], shifted maxillary midline was classified by both male and female (4 th -and 5 th -year) dental students as unacceptable. Alhammadi and co-workers report that the dental students in their study noticed as small a shift as 1 mm [23]. It seems, thus, that the position of the maxillary midline is a sensitive esthetic issue, so it came as no surprise that in our study it was one of the parameters significantly associated with the stage of studies.…”

“…They drew the conclusion that women were "more critical" regarding these features. Finally, Alhammadi and colleagues [23] studied 408 Saudi Arabian dental students, and came to the conclusion that "male dental students have a better perception of facial and dental esthetics." It is not clear if the remarkable difference between the results of these studies is due to the different geographical locations, the difference between the studied features or something else.…”

Background How dental education influences students' dental and dentofacial esthetic perception has been studied for some time, given the importance of esthetics in dentistry. However, no study before has studied this question in a large sample of students from all grades of dental school. This study sought to fill that gap. The aim was to assess if students' dentofacial esthetic autoperception and heteroperception are associated with their actual stage of studies (grade) and if autoperception has any effect on heteroperception.

“…El instrumento de evaluación utilizado fue la escala VAS la cual brinda un puntaje confiable (30) y es un método de uso común para nociones subjetivas como el dolor, atractivo y ansiedad en investigaciones de ciencias de la salud; aunque existe la tendencia de algunos evaluadores de no utilizar toda la escala debido a que tienen temor de dar una calificación alta a una imagen, en caso de que la siguiente les parezca más estética (31), para compensar esto y limitar el posible cansancio visual se decidió evaluar sólo tres posiciones en cada una de las variables estudiadas, a diferencia de otros estudios en dónde evaluaron mayor cantidad (1)(2)(3)(4)(5)(8)(9)(10).…”

“…En los últimos años la búsqueda de una adecuada estética facial y dental, ha tomado mayor importancia para los pacientes, siendo la sonrisa un elemento primordial en ello. Actualmente es frecuente someterse a diferentes tratamientos estéticos y cosméticos en las diversas especialidades médicas y odontológicas, sin embargo, no existe un consenso entre ortodoncistas, dentistas, estudiantes de odontología, pacientes y personas comunes en lo que se considera una sonrisa estética (1)(2)(3)(4)(5), esto se debe posiblemente a la naturaleza subjetiva de la sonrisa y a que durante muchos años solo se tomó en cuenta la opinión de algunos autores y no de una literatura basada en evidencias (6,7). Es importante mencionar que en la planificación del tratamiento ortodóntico y en la finalización, el objetivo principal ha sido lograr una oclusión estable con una adecuada función y esto no necesariamente coincide con una sonrisa estética en el sector anterior (8)(9)(10).…”

Objective: To evaluate the esthetic perception of the smile according to the variation of the vertical position and the angulation of the upper central incisor (UPI) by dental students (DS) and common people (CP) of three regions of Peru. Materials and Methods: Descriptive cross-sectional design. The sample was 462 adults, divided into 77 for each subgroup of DS and CP of the Lima (Coast), Junín (Highlands) and Loreto (Rainforest) regions. Using the Photoshop® software, a photograph of a woman's smile was modified by varying the vertical position and angulation of the UPI, obtaining images that were evaluated using the analog visual scale. Results: The CP rated better than DS in most categories (p <0.001). The smile best valued by DS in a vertical position was 1mm and 2mm; and for angulation 0°, while for CP 1mm and 0° respectively (p <0.05). Comparing by regions, the DS of Lima gave the lowest rating for 0 ° with 52.63 and those of Junín the highest for 4° with 45.90. The PC of Loreto registered the lowest score for the vertical position categories (p <0.001), while for angulation in Junín it was rated with a lower score than in Loreto for -6 ° and 0 °; and for 4° Lima provided the lowest rating (p <0.001). Conclusions: The esthetic perception of the smile is affected by the variation of vertical position and angulation of the ICS in common people and dental students in the three regions of Peru.
