Fulfilling aesthetic norms is an imperative of modern society. Accordingly, aesthetics has found its important role in dental medicine. The aim was to study whether there is a difference in the perception of tooth shade change and anatomical variations of anterior maxillary teeth among dental students depending on the level of education, gender, and experience in assisting in a dental office.
The research was conducted among dental students via the Google Forms platform. Students evaluated the aesthetic acceptability of a smile on the unaltered, reference photograph (RP) and on the other 28 photographs in which the tooth shade (lighter and darker teeth), length (shortened central incisors, elongated, and beveled lateral incisors, elongated canines) and position (atypical and typical rotations and diastemas) of the upper maxillary teeth were altered by digital manipulation. The 1-10 assessment scale was used. Statistical analysis comprised one-way Kolmogorov-Smirnov test, X tests, t-test, and 3-way MANOVA.
In the research 208 students participated, 113 were preclinical students, 104 assisted in dental office and 175 were females. There were no significant effects of gender regarding length and position modifications (p > .05), while women were stricter in evaluation of lighter shade (p < .05). Clinical students were stricter in evaluating all manipulated photographs (MP) except those towards darker shade modifications, while assisting in a dental office or having a dentist in close family showed no significant effects (p > .05).
With a higher level of targeted academic education, dental students sharpen their ability to notice deviations from the aesthetic norms of a smile.
满足审美规范是现代社会的必然要求。因此，美学在牙科医学中找到了重要的作用。本研究旨在探讨牙科学生对牙色变化和上颌前牙解剖变异的感知是否存在差异，这种差异取决于教育水平、性别以及在牙科诊所协助的经验。
通过 Google Forms 平台在牙科学生中进行了这项研究。学生们通过 1-10 的评估尺度，对未经修改的参考照片（RP）和另外 28 张照片上的微笑美观接受度进行评估，这 28 张照片中，上颌前牙的牙色（更浅和更深的牙齿）、长度（缩短的中切牙、伸长和倾斜的侧切牙、伸长的尖牙）和位置（异常和典型的扭转和间隙）通过数字处理进行了改变。统计分析包括单向 Kolmogorov-Smirnov 检验、X 检验、t 检验和 3 向 MANOVA。
共有 208 名学生参与了研究，其中 113 名是临床前学生，104 名在牙科诊所协助，175 名是女性。性别对长度和位置的改变没有显著影响（p>.05），而女性对更浅的颜色改变的评价更严格（p<.05）。临床学生对所有处理过的照片（MP）的评价更为严格，除了对更暗颜色改变的评价外，而在牙科诊所协助或有牙医在近亲家庭中并没有表现出显著的影响（p>.05）。
随着目标学术教育水平的提高，牙科学生提高了发现微笑审美规范偏离的能力。
