Background: The prominence of the chin is an important factor in the perception of facial attractiveness, but the concept of a beautiful face is innate to each human being and surpasses cultural differences.Thus, knowing the perception of those involved in an ortho-surgical planning is paramount to the success of the treatment. Objectives: This work carried out an objective and quantitative evaluation of the degree of influence of the prominence of the ment in the perception of attractiveness of patients, orthodontists and surgeons. Finding objective evidence to assist the reader in the surgical planning of patients with dentofacial deformity. Method: For this the pogonium of an ideal profile image was created through the adobe photoshop program, this silhouette was altered in increments of 2 mm ranging from -12 mm to 24 mm, with the aim of representing retrusion and protrusion of the chin, respectively. Estas imagens foram classificadas através de uma escala de Likert de 7 pontos, a qual variava de extremamente não atraente até extremamente atraente. Além disso, os sujeitos da amostra responderam para cada imagem se indicavam ou não a cirurgia. The sample was divided into 4 groups: 44 orthodontists, 44 surgeons, 44 class II patients and 43 class III patients selected for convenience and consecutively. The study was approved by the Research Ethics Committee of the Federal University of Sergipe (CAAE: 51021315.2.0000.5546). Categorical variables were expressed in absolute and relative frequencies. The quantitative variables were represented as medians and average. Inferential analysis was performed using kruskal wallis and chi-square tests. Values of p <0.05 were considered significant. Results: The participants were predominantly female (59.4%). There was a divergence in the aesthetic evaluation (p <0.05) of the groups for almost all analyzed profiles. The class II profiles were better evaluated when compared to the class III profiles. The profile that was better evaluated was the profile that presented the 4 mm pogonion in relation to the true vertical line. The frequency of indication of the surgical procedure found a positive correlation (X2 <0.05), a group of maxillofacial surgeons was more likely to indicate surgery. The sex of the interviewee did not influence the frequency of indication of the surgery (X2 = 0.092), men and women were equally likely to indicate the surgical procedure against the presented profiles. The age of the interviewee influenced the indication of the surgery for the class II patients when analyzing all the profiles (X2 = 0.014), as well as for the Class III patients, taking into account only the Class II (X2 = 0.036) profiles, Interviewees of these groups over 31 years of age were more likely to indicate the surgical procedure. Conclusion: During planning, surgeons and orthodontists should always individualize their decisions, but offering the patient a straight or slightly class II profile seems to be the most supported approach in the present study.
