The present study aims to analyse the smiling components among young adults within Al Qassim region by evaluating typical smile parameters. . 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.
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 ( < 0.05).
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.
本研究旨在通过评估典型的微笑参数,分析卡西姆地区年轻成年人的微笑组成部分。在沙特阿拉伯卡西姆省,对324名年龄在18至35岁之间的女性和男性参与者进行了一项横断面研究。使用佳能Rebel t7i(佳能,美国纽约梅尔维尔)确定微笑的牙龈宏观美学元素、切缘曲线与下唇线之间的平行度、中线和颊廊,并通过照片编辑软件Adobe Photoshop CC2019进行评估。使用卡方检验和Spearman相关性检验对非参数数据进行分析。
62.5%的年轻成年人没有颊廊。53.2%的年轻成年人存在非平行微笑。33%的参与者观察到高微笑线。59.3%的年轻成年人缺乏一致的牙中线和面部中线。切缘曲线与下唇线的平行度以及上唇线的位置在性别之间存在统计学显著差异(<0.05)。
了解牙齿的宏观美学元素及其与周围口腔结构的相互关系可为创建自然且美观的修复治疗提供指导。
