“…This pattern was also observed in a recent study that used a methodology and sample similar to this study. 31 This analysis can lead to the consideration that possibly these groups possess different levels of knowledge in the field of dentistry, even though neither has ever received any dental education. This finding might be explained by the fact that the patient enjoyed greater contact with dental issues throughout the orthodontic treatment.…”

“…Existe múltiples factores relacionados a la estética de la sonrisa (16) que pueden dividirse en microestética, estética gingival, macroestética y estética facial (17), de los cuales se puede mencionar que las líneas de sonrisas rectas o invertidas se consideran menos atractivas (7,18), mientras que las líneas convexas son consideradas más bellas y jóvenes (19); tomando suma importancia la posición vertical del incisivo central superior(ICS) (7)(8)20,21) y su relación con el borde incisal del incisivos lateral superior(ILS) (8,22) para que una sonrisa sea considerada atractiva o 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.

“…Then they could be difficult to detect visually and therefore, they may not be perceived as antiesthetic. 5,12,15,38,42 The findings of this research showed that few irregularities in microesthetics values may be expected in orthodontically treated patients when compared to the Normal Occlusion patterns. In general, both groups presented similar behavior of the studied variables.…”

“…2,5,[13][14][15] Symmetry between sides has been reported as an important characteristic in microesthetics. 5,12,38 Despite the statistically significant differences found for central incisor width/height symmetry proportion in the Normal Occlusion group, and for the canines width/height symmetry proportion and central incisors gingival zenith in the Class I group (Tables II and III), they were numerically minimal. Then they could be difficult to detect visually and therefore, they may not be perceived as antiesthetic.…”

“…Nevertheless, this difference could be considered without clinical significance because in general dentists and laypeople do not perceive microesthetics alterations of less than 1mm. 5,12,38 The lack of difference between groups for width/height proportion could be explained because, this rarely change with orthodontic treatment. This could happen when associated to periodontal intervention, in case of orthodontic extrusion followed by periodontal surgery.…”

The aim of this research was to compare the microesthetics characteristics of the maxillary anterior tooth in individuals with Class I malocclusion treated with four premolars extractions in relation to normal occlusion as well the evaluation of symmetry between right and left sides in both groups. Methods: The sample was divided into two groups, first one with Angle Class I malocclusion treated with four premolars extraction (mean age of 15.18 and composed by 22 female and 9 male patients), and second one with Normal Occlusion (mean age of 16.93 and comprised by 15 female and 16 male individuals) composed by 31 individuals each. Objective grading system index (OGS) was evaluated in the plaster models of both groups and then digitized in 3D 3Shape R700 scanner (3Shape A/S, Copenhagen, Denmark). The width/height proportion of anterosuperior teeth, zenith location, height of connectors and gingival contour were measured with OrthoAnalyzer™ 3D program. Random and systematic errors were respectively evaluated with Dahlberg's formula and paired t tests. Mann-Whitney U and t tests were applied to variables without and with normal distribution respectively. Results: In most comparison there was no significant differences between groups. It was noticed in a few situations that Class I group presented significantly greater width/height proportion in 12 than Normal Occlusion; significantly smaller gingival zenith of 23, significantly greater connector in 22 to 23 and also significantly greater gingival contour in right side in comparison to Normal Occlusion group. Both sides of Class I and Normal Occlusion groups presented symmetry. Conclusion: Four premolar extractions orthodontic treatment of Class I malocclusion provides similar microesthetic patterns as individuals with normal occlusion. Both groups generally present symmetric microesthetic characteristics.
