This study aimed to assess the association between self-rated smile satisfaction and the smile dimensions among dental students.
An analytical cross-sectional study was conducted on 216 Vietnamese dental students. A standardized photograph was taken of each student with their frontal social smiles to assess aesthetic dimensions. A single-session self-administered questionnaire containing five questions about smile aesthetic satisfaction related to various aspects was administered to all students. Differences in smile characteristics and satisfaction scores between the two genders were evaluated. The impact of smile characteristics on satisfaction scores was assessed using multiple linear regression models.
Most dental students had a high smile line, parallel smile arcs, an upward upper lip curvature, a non-touching labiodental relationship, a dental midline that coincided with the midline of the face, and eight teeth displayed during smile. Most participants were satisfied with their smiles, and the self-rated satisfaction score was 67 out of 100. Self-perceived overall smile satisfaction was associated with the "smile arc", the "upper lip curvature", the "number of teeth displayed during smile", and the "dental midline". Female students had a statistically significant correlation between self-perception and smile characteristics, such as upper lip curvature, dental midline shift, and smile line.
The smile arc, upper lip curvature, and dental midline shift affected self-perceived satisfaction among dental students. Female students showed an association between the smile parameters and self-perceived satisfaction.
本研究旨在评估牙科专业学生自评微笑满意度与微笑维度之间的关联。
对216名越南牙科专业学生进行了一项分析性横断面研究。为每名学生拍摄标准化的正面社交微笑照片，以评估美学维度。向所有学生发放一份包含五个关于微笑美学满意度不同方面问题的单环节自填式问卷。评估了两性之间微笑特征和满意度得分的差异。使用多元线性回归模型评估微笑特征对满意度得分的影响。
大多数牙科专业学生微笑线较高、微笑弧线平行、上唇呈向上弯曲、唇齿关系不接触、牙中线与面部中线重合，微笑时露出八颗牙齿。大多数参与者对自己的微笑感到满意，自评满意度得分为满分100分中的67分。自我感知的总体微笑满意度与“微笑弧线”、“上唇弯曲度”、“微笑时露出的牙齿数量”和“牙中线”有关。女学生在自我认知与微笑特征（如上唇弯曲度、牙中线偏移和微笑线）之间存在统计学上的显著相关性。
微笑弧线、上唇弯曲度和牙中线偏移影响牙科专业学生的自我感知满意度。女学生在微笑参数与自我感知满意度之间存在关联。
