Abstract
Objectives The present study aims to analyse the smiling components among young adults within Al Qassim region by evaluating typical smile parameters. Methodology. A cross-sectional study was conducted among 324 female and male participants between 18 and 35 years, within Al Qassim Province of Saudi Arabia. The dentogingival macro-aesthetic elements of the smile, the parallelism between the incisal curve and lower lip line, midline, and buccal corridors were determined by using Canon Rebel t7i (Canon, Melville, NY, USA) and evaluated by photo editing software Adobe Photoshop CC2019. The data were analysed using a chi-square test and Spearman's correlation test for nonparametric data. Results 62.5% of young adults had no buccal corridors. The nonparallel smile was found in 53.2% of young adults. A high smile line was observed in 33% of participants. 59.3% of young adults lacked a coinciding dental and facial midline. There was a statistically significant difference in the parallelism of the incisal curve and lower lip line as well as in the position of the upper lip line across genders (P < 0.05). Conclusion Understanding macro-aesthetic elements of teeth and their interrelation with the surrounding oral structures can be a guide in creating natural and aesthetically pleasing restorative treatment.
Highlights
Smiling is one of the most critical facial expressions and is known as a nonverbal parameter of correspondence [1]
Few criteria are used for smile analyses of young individuals [6, 7, 10, 12, 24, 25]. e purpose of this study was to evaluate and analyse dentogingival macro-aesthetic elements of the smile of young adults within Al Qassim Province
Limited research has described the smile components of young adults in Saudi Arabia, research has yet to be conducted within Al Qassim region [6, 7]
