Aim: The aim of this observational study was to assess the different esthetic smile criteria of adults in Saudi Arabia. Further goals were to find the predominant dental shades and assess subjects' esthetic perception in a sample of Saudi community.
Materials and Methods: Thirty subjects were recruited from King Abdulaziz University Dental Hospital in Jeddah, Saudi Arabia. Subjects were between 18-50 years of age with intact upper anterior teeth and healthy gingiva. All participants were photographed and the following smile parameters were recorded: tooth geometry, shade, midlines, smile arc, and upper lip position. Parameters were plugged in a dedicated smile analysis software and the golden proportion values were obtained. Data were analyzed using Chi Square and Student's t-tests according to variables tested at 0.05 significance level.
Results: Regardless of age and sex, 70% of the sample has an average lip position, and consonant smile arc was the prevalent form among 73.3% of the sample. The most common shade was A2 regardless of tooth type or position. Almost half of the participants were satisfied with their overall appearance and only 6 subjects were not satisfied with the size of their teeth. Overall, the golden proportion was not present in the tested sample.
Conclusion: Despite the absence of golden proportion, the majority of the sample tested was satisfied with their smile parameters. The prevalent shade was A2 in both genders.
