Dentogingival Smile Analysis of Young Adults of Al Qassim Province, Saudi Arabia: A Cross-Sectional Study

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.

Evaluation of esthetic parameters of the face and components of smile in children with deciduous dentition

“…5 Smile esthetics can be evaluated by clinical examinations, direct facial measurements, 6 from photographs 7 or by utilizing laser scanning techniques 8 and computerized methods. 9 Photographs allow the observation of harmonious relationship between soft and hard facial tissues, at a low cost without exposing the patient to radiation. Most frequently captured photographic views for evaluating facial esthetics are profile image, frontal image with the lips together, and frontal smiling images which allows complete visualization since dynamic characteristics are not taken into consideration.…”
