“…In straight, anterior, and posterior divergences, Image C with average lip position was regarded the most preferred lip position, and Image E with +4 mm lip protrusion was considered the least preferred lip position among orthodontists, dentists, and laypeople, which is comparable to the study done by Zarif Najafi et al .

Aim: The aim of this study was to establish the most and least pleasing lip position and to evaluate esthetic preference in profile view among the South Indian population with diverse facial divergence. Materials and Methods: Photographs of 12 participants with an average lip position were taken, and original lip position (Image C) was altered by ± 2 mm and ± 4 mm from the original position of upper and lower lips using Adobe Photoshop 7.0 version. Image A and Image B comprised photographs with retrusive lips of 4 mm and 2 mm, respectively, and Image D and Image E comprised photographs with protrusive lips of 2 mm and 4 mm, respectively. The altered photographs were evaluated for pleasing lip positions by 300 examiners which comprised 102 orthodontists, 107 general dentists, and 91 laypersons. Results: A questionnaire was conducted through Google Forms, and the examiners favored Image C with an average lip position as the most desired lip position, whereas Image E with 4-mm lip protrusion and Image A with 4-mm lip retrusion were the least desired irrespective of gender or facial divergence. Conclusion: Importance to establish appropriate soft-tissue esthetics is the primary concern of an orthodontic treatment.

“…Image E (followed by Image A) was shown to be the least appealing lip position in anterior divergent males and females in all three groups, which is consistent with the findings of Zarif Najafi et al . [ 13 ] The most appealing lip position was Image C, followed by Image B.…”

Porém, o diagnóstico de harmonia facial e a obtenção desta, pode ser considerada uma tarefa desafiadora, devido à natureza subjetiva da avaliação e percepção da estética facial Bergman, 1993;Maple et al, 2005;Rino Neto;2006 (Downs, 1948;Ricketts, 1957;Burstone, 1958;Marrifield, 1966;Holdaway, 1983;McNamara,1984;Bishara et al, 1985;Czarnecki et al, 1993;Bergman, 1993;Arnett et al, 1999;Spyropoulos;Halazonetis, 2001), e a importância do equilíbrio entre o nariz, lábios e mento, parece ser um concenso entre os autores (Ricketts, 1957;Marrifield, 1966;Holdaway, 1983;McNamara, 1984;Bishara et al, 1985;Czarnecki et al, 1993;Bergman, 1993;Maple et al, 2005, Coleman et al, 2007Naini et al, 2012;Modarai et al, 2013;Park et al, 2013;Najafi et al, 2016).…”

Linhares DS. The relation between the projection of the lower third of the face and the region of the glabella [dissertation]. São Paulo: Universidade de São Paulo, Faculdade de Odontologia; 2017. Versão Corrigida.The lower third of the face exerts a strong influence on the aesthetics of individuals, and knowing the importance of its balance, and the orthodontist's contribution to the diagnosis of the facial profile, the present study had the purpose to test a method of correlation between a linear measure located from the glabella region with linear anteroposterior measurements on the lower third of the face (Triviño, 2012), and verify the predictability of anteroposterior proportions in the lower third of the face, from a reference line through a point in the glabella region. Anatomical tracings from lateral cephalometric radiographs of 120 individuals with balanced profile, leucoderm and class I were performed in order to establish cephalometric parameters to correlate anteroposterior references of the lower third of the face from the lines Sv-PRT and PRTv, obtained through the PRT point. The applicability of the method was performed in a group of 24 individuals with an unpleasant profile, in which it considered the predictability formulas that used the Sv-PRT line as an unsatisfactory reference to determine the anteroposterior proportions of the lower third of the face in some patients. The method that considered the PRTv line as a reference, using Pearson's statistical methods of correlation and multiple linear regression, presented statistically significant results for all reference values in females and males (PRTv-Ls, PRTv -Li and PRT-Pg'). The Student t-test was used to verify that the measures were not statistically significant according to gender. The results of this study showed that it is coherent to consider the glabella region as an evaluation and diagnostic reference for the anteroposterior proportions of the lower third of the face.
