Objectives: The aim of this study was to determine the parameter of the four esthetic factors of smile: Smile line, smile arc, upper lip curvature and number of teeth displayed in the smile following sex and valuating the esthetic quality of the smile according to esthetic factors type. Materials and methods: Digital images of natural smiles on 100 freshman students in 2018-2019 (58 male and 42 female) Can Tho University of Medicine and Pharmacy were recorded Sofware (Adobe Photoshop 7.0.1) was used to process images. We choose 50 students of the Faculty of Odonto-Stomatology and 50 other students to evaluate the level of esthetics of the chosen smiles by 5 levels not Very beautiful, not beautiful, Normal, Nice, Very beautiful and compare the differences in opinions of these two groups. Results: Aesthetic distribution of smiles by gender: (n male=58, n female=42). The figure for male shows that the most popular smile line is high smile line (type 2) accounting for the percentage of 50%, which is different from female, where the most popular is average smile line (50%). In both male and female, consonant smile arch accounted for the highest proportion 46.6% and 61.9%, respectively. The most common type of male upper lip curve is straight (41.4%). While this figure in women is the upward curvature. There are similarities in the evaluation of both groups of students: Smile with the upper lip curve straight upper lip lines is considered as the most beautiful smile. Conclusion: The study has provided some data on aesthetic distribution of smiles on Vietnamese people aged 18 to 25 and has also shown that students of Odonto-Stomatology have more rigorous assessment of the smile aesthetic than the others.
