Facial esthetics have an important function in psycho-social relations and is a response to anatomical and muscular dynamics; differences in facial skull position can modify a subject’s facial esthetic and smile. The aim of this research is to know smile esthetics and the presence of facial modifications. We studied standardized photographs of patients between 18 and 37 years old and determined soft tissue relation to identify the facial class in lateral images defined as class I, II or III; we analyzed their relation to dental/ gingival presentation in reference to a high, normal or low smile. The data was analyzed in a descriptive technique. The results show that the low smile has a minor percentage and a normal smile was present in 47.62% of class I subjects, 34.29% of class II subjects and 75% of class III patients; high smile was present in 54.29% of the class II subjects; the buccal corridors, as an esthetic element follows the normal parameters in a low percentage and the greater or lesser size of the buccal corridors was observed in 71.43% of class I subjects, 74.29% of class II subjects and 75% of the class III subjects. It was concluded that mayor variations exist in the smile of subjects with different facial class and that the buccal corridors was excessive in the majority of subjects, thereby demonstrating the importance of analyzing this concept of esthetics in our population.
