OBJECTIVE: The objective of this study was to determine the components of the smile according to the facial proportions in patients from 16 to 20 years in the first and second level of the UNAP dentistry faculty. MATERIALS AND METHODS: The type of research was descriptive and the research design was transversal retrospective. The sample was students of both genders between 16 and 20 years of the faculty of dentistry of the National University of the Peruvian Amazon that correspond to students of the first and second level of the year 2016. A chair with backrest was used located at 70 cm from wall. A metal stand was also placed on the side of the chair, from which a plumb line was made to determine the true vertical. A tripod was placed, which was used to support the semiprofessional camera Nikon DX 18-55mm f / 3.5-5.6 III 24MP - Black, located 90 cm from the chair. An environment with adequate and standardized lighting was selected. The sample was taken in two stages. A data sheet was used. The second moment of filling was done by having the selected photographs of each individual, where we proceeded to complete the 8 components of the balanced smile of Roy Sabri. It was done with the vernier, which was modified to achieve the bicigomatic measurements. The facial pattern was obtained through the morphological facial index. The facial type of patients was determined with the vertical distance between the nasion point to the gnation divided by the bicigomatic width multiplied by 100. Having the patient in its natural position, we proceeded to place the semi-professional camera (Nikon DX 18- Camera 55mm f / 3.5-5.6 III 24MP - Black). The photographic shot consisted of taking 3 full-face photographs of the patient's smile with the camera (in manual mode, with aperture value F 4.2 and adjustment of speed 1/60, normal quality and with flash) connected to a tripod with its height adjusted so that the center of the lens has aligned with the sub - nasal point of the patient. The photographs were evaluated in the first instance, discarding the group of photographs that did not meet the aforementioned requirements. Each photograph was evaluated by visual perception using the Windows image and fax viewer program, making a 5+ approach to photography and focusing the lower third on the computer screen. The results of the analysis were recorded in the data sheet. RESULTS: Within the result, the following was obtained: The most frequent facial pattern was Leptoprospop in a (64.6%). The high smile predominated (62.5%). There was no statistically significant difference. The absence of negative spaces was what predominated in the facial patterns euriprosopo, mesoprosopo and leptoprosopo with 83.3%, 63.6% and 64.5% respectively. It was found that the leptoprosopos patients presented in a 83.3% a high smile and 32.3% in an average smile, in addition there was a low smile frequency in the mesoprosopos. It was found that Mesoprosopic patients usually have an average smile (27.3%). It was found in greater proportion to those that present a high curvature of the upper lip (39.1%) but it differs in that there was a smaller number of subjects with a low curvature of the upper lip (24.1%). In this study done in the Peruvian population, it was found, according to the results, that the absence of negative spaces predominated in women and men in its majority. There was no statistically significant difference. The relative positioning of the commissures in the vertical plane called symmetry of the smile could be symmetrical or asymmetrical. In this study we found a tendency to have an asymmetrical smile (81.3%), which does not indicate a good facial aesthetic of this population. No statistically significant difference was found. The frontal occlusal plane of patients tends to be acceptable (52.1%) in its majority. No statistically significant difference was found. The dental component is one of the most seen aspects in the smile, despite this population has a tendency to be "not acceptable" (56.3%) in its majority. No statistically significant difference was found. In a smile, generally what less is seen is the gingiva. Therefore, the gingival component cannot be analyzed correctly in a smile analysis. In spite of this, it is an important component within a balanced smile, for which we must take into account. Thus, in this population it was found that there is a tendency to present an acceptable gingiva (52.1%) in its majority. No statistically significant difference was found. It was not possible to establish equal samples of both genders (female and male), which indicates that there are no differences between such groups. In this work, it was found that both women (72.7%) and men (57.7%) with a facial pattern Euriprosopo (100% and 66.7%), Mesoprospop (66.7% and 50%) and Leptoprosopo (68.8% and 53%) respectively, they present a high smile. No statistically significant difference was found. CONCLUSION: In the analysis of the smile in relation to the facial proportions in students of the first and second level of the faculty of dentistry at the National University of the Peruvian Amazon in 2016 it was concluded that there is a relationship between the elements of the smile and the facial patterns.
