Photographic analysis of the soft tissue facial profile in young adults

Abstract

To make a correct diagnosis in orthodontics it is very important to know the relationship between hard and soft tissues. Objective. To characterize the measurements of the facial profile of soft tissues in students of School of Dentistry at the Central Universidad Central del Ecuador (FOUCE) period 2020-2020. Materials and Methods. Cross-sectional study, with a sample made up of 60 students (30 women and 30 men) between 18 and 25 years of age who met the inclusion criteria. After signing the informed consent, a photograph of the facial profile was taken in a natural head position. Soft tissue facial profile angles were identified and measured with the Viewbox program. The data were analyzed with the SPSS software applying the T-Student test with p value 0.05 to identify differences in the measurements between men and women. Results. The average values of the facial profile of soft tissues of the nasofrontal angle (GN-Nd, p = 0.019), projection of the upper lip-chin (N-Pg / N-Ls, p = 0.006), projection of the lower lip chin and upper lip angle (Sn-Ls / Sn - Pg, p = 0.000) had statistically significant differences between men and women. Conclusions. A significant sexual dimorphism phenomenon in the parameters of the nasofrontal angle, were found. Projection of the upper lip chin, projection of the lower lip chin and angle of the upper lip that must be considered when diagnosing adult individuals.
