“…In addition, smile aesthetics are strongly affected by the subjective perception of each individual. Dentists, who often have to deal with aesthetic issues, may be more subtle than non-professionals [5,6]. However, the non-professionals are the aesthetic customers who pay for dental specialties.…”

Aim: It is important to meet the aesthetic expectation regarding the smile concept of both dentists and non-professionals after treatment is complete. Therefore, the study aims to evaluate the effects of altered displays in incisors, gingival margin, and other smile-related-factors on dentists’ vs. non-professionals’ aesthetics perceptions. Materials and method: We altered the features of 42 digital smile photographs to generate the changed displays in incisors, gingival margin, and other smile-related-factors. Then, these altered photographs were presented to 51 dentists and 51 non-professionals, and each picture was rated by each participant with a visual analog scale ranging from 0 (very ugly) to 100 (very beautiful). Results: We found that the alterations in incisors, gingival margin, and other factors affected studied groups’ aesthetic perception of smile. The ugly smile threshold rated by both groups for crown length of maxillary central incisors was 2.0 mm. This threshold was 2.5 mm for dentists, with moving the gingival margin of maxillary lateral incisors to the incisal ridge. The ugly thresholds for other smile-related-factors were different between studied groups; for example, the ugly thresholds for gingival exposure levels were 3 and 4mm for dentists and non-professionals, respectively. Thus, our data indicate that altered displays in incisors, gingival margin, and other smile-related-factors affected perceptions of both studied groups on smile aesthetics, but dentists tended to feel more refined than non-professionals. Dentists and non-professionals had significantly different aesthetic perceptions of the alteration of the gingival exposure level. Conclusion: Both dentists and non-professionals’ perceptions should be fully considered during orthodontic and prosthodontic treatment to achieve optimum aesthetic results.

“…In this context, the observer´s knowledge and experience is one of the most influential factors [ 1 ]. Several studies have compared the perception of smile esthetics among lay people with different professional backgrounds [ 4 ], general dentists [ 5 – 9 ], and orthodontists [ 10 – 12 ]. Most of these studies agree that the more specialized training the observer has received, the more sensitive his/her perception of smile esthetics will be [ 1 ].…”

One of the main objectives of orthodontic treatment is to achieve an esthetic smile. This study set out to analyze differences in the perception of smile esthetics among patients before and after receiving orthodontic treatment. 250 Spanish patients analyzed a single photograph in which, by means of computer software, midline diastema, black triangle, gingival margin of the left central incisor, and gingival (“gummy”) smile were altered. Each patient analyzed these images before and after undergoing orthodontic treatment. Patients scored the photographs on a scale from 1 to 10. Statistical analyses of each group’s level of perception were carried out, identifying significant differences in evaluations before and after treatment, and in relation to subjects’ gender and age. Patients presented significant differences in the esthetic perception of midline diastema and gummy smile anomalies after they had completed orthodontic treatment. Gender influenced the perception of smile esthetics, whereby women were significantly more critical of midline diastema, black triangle and gingival margin of the upper central incisor than men. The age variable also showed significant differences in the perception of midline diastema and black triangle anomalies. The perception of smile esthetics of some dental anomalies changes as a result of orthodontic treatment. Gender influences the perception of some of the dental anomalies studied.

“…Nuestro análisis de datos para la posición vertical del ICS nos muestra que las personas comunes solo dieron una mayor calificación que los estudiantes de odontología con diferencias estadísticamente significativas solamente en la categoría de 1mm, resultados que se oponen parcialmente a lo reportado en estudios previos (3,33) en donde se encontró que los dentistas son más críticos que las personas comunes y dan puntajes menores en la mayoría de los casos. En nuestro estudio no se estaría encontrando esta diferencia, posiblemente porque los estudiantes de odontología son un grupo que aún se encuentra en formación académica y no tiene definido por completo los conceptos de sonrisa estética.…”

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.
