Three Smile Components on Different Facial Types of Young Adult Population in Makassar

Indonesia has various ethnics with different types of facial shapes and smiles. The facial shape, the condition of the teeth, and surrounding tissues significantly affect the esthetic smile. The study aimed to assess the three smile components on facial types of Senior High School children in Makassar, Indonesia. The subjects involved 198 students at three Senior High Schools. Each subject was photographed while smiling from the frontal direction and saying long "cheese”. The images were measured with Adobe Photoshop CS6 program to determine the facial type and the lip line, smile arc, and smile symmetry. The data were analyzed using Chi-square statistical test. There were no significant relationships between the facial type and lip line, smile arc, as well as smile symmetry, but there was a significant relationship between gender and smile arc, as well as smile symmetry. The highest percentage of the student’s facial type was mesofacial and the highest percentage of lip line position found in all facial types was the medium.
