N2 - Chilean population is characterized for being heterogeneous, due to a large variety and mix of different ethnicities and races. This includes diversity in shapes, sizes and thickness of anatomic structures, part of which is facial thickness. Even though there are databases of facial tissue thickness for Chilean population, these have been carried out through techniques such as ultrasonography and puncture, without taking into consideration radiologic techniques, such as profile teleradiography. The aims of the study were: 1. Measure tissue thickness at GB and NA level, 2. Evaluate correlation in thickness according to distribution per sex and biotype. 3. Compare thickness among the groups. 4. Create a database of soft tissue thickness at GB and NA level in Chilean population, 5. Compare results with other studies regarding tissue thickness in Chilean population. Ninety-nine dentistry students between 20 and 27 years of age, candidates for orthodontic treatment, were randomly chosen. Lateral teleradiography was requested from all individuals, soft tissue thickness was measured at GB and NA level, classifying patients according to Roth-Jaraback analysis. When analysing the results according to sex, larger thickness was observed in men each time, with a significant difference at GB and NA levels. When evaluating biotype differences no significant difference was observed. Men showed thicker soft tissue at NA and GB level than women, with a significant difference between both. A new classification is proposed according to biotype, but no concluding data is found.
