Smile being one of the aesthetic parameters most required by patients, dentists tend to evaluate it, among other factors, according to the amount of gingiva that the patient shows when smiling. This smile can be classified as high, medium and low. For correct interpretation and good diagnosis should also be analyzed soft tissue, such as the periodontal biotype, it can be thin and thick. The reason for our investigation is to observe the relationship between the type of smile and the periodontal biotype. The cross-sectional analytical study was performed on 100 UCSG dental students, randomly selected according to the inclusion and exclusion criteria. The type of smile was determined, whether it was high, medium or low. The periodontal biotype was determined by two methods: the visual, in which the clinical characteristics of each were analyzed, and by the transparency or not of the probe, through the gingival sulcus in the teeth 11, 12 and 13.  Were analyzed 100 subjects, 33 men and 67 women.  27% of the total of the subjects had high smile, 65% showed average smile and the 8 % low smile. 70% showed to have thick biotype while 30% remaining fine biotype. When relating the two variables, of high smile 15%=thin biotype and 85%=thick biotype, of low smile 25%=thin biotype and 75%=thick biotype and of low smile 37%=thin biotype and 63%=thick biotype.
