Tooth shade differentiation concerns the identification and classification of tooth shades. The objective of this project was to implement the Clinical Tooth Shade Differentiation Course in the preclinical stage of studies and to evaluate the students' perspective over a period of 3 years.
The course is planned for a duration of 10 weeks with two 45-minute sessions per semester week. The entire attendance time was 10:15 h. 2 lectures of 90 minutes each, 2 seminars of 60 min each and 2 teaching units with the phantom head and role playing took place. In addition to the various parameters of tooth shade, changes in tooth shade and the basics of dental esthetics, clinical procedures for manual and digital tooth shade determination were explained and practiced. 96% (69 of 72) of the students participated in the first evaluation in 2012/2013 (T1), and 68% of these were women. In the following year, 2013/2014 (T2), 92% (45 of 48 students) took part; 62% of these were women and 38% men. The 2014/2015 evaluation (T3) comprised 94% (45 of 48 students). Of these, 67% were women.
In the evaluation, the students gave the course a positive grade. The questions in "General/Organization" were given a mean (M) of 1.5 (SD=0.7) in T1 and T2, and 1.2 (SD=0.3) in T3. The "Overall Assessment" yielded M(T1)=1.6 (SD=0.6), M(T2)=1.5 (SD=0.5) and M(T3)=1.1 (SD=0.3). In T1 and T2, the item "The instructor actively involved the students in the course" was given a mean of 2.1 (SD=0.9), and in T3 a mean of 1.2 (SD=0.5).
The course presented here conceptually shows how practical dental skills can be taught in a theoretical and clinical context. Educational objectives from the role of a dental expert were taken from the national competence-based catalog of educational objectives for dentistry and can also be supplemented. The objectives can be transferred to other dental faculties.
牙齿色泽鉴别涉及牙齿色泽的识别与分类。本项目的目的是在临床前学习阶段开展临床牙齿色泽鉴别课程，并在3年时间里评估学生的看法。
该课程计划为期10周，每周两个45分钟的课时。总出勤时间为10小时15分钟。共进行了2次每次90分钟的讲座、2次每次60分钟的研讨会以及2个使用仿真人头和角色扮演的教学单元。除了牙齿色泽的各种参数、牙齿色泽的变化以及牙齿美学基础外，还讲解并练习了手动和数字牙齿色泽测定的临床操作。2012/2013学年（T1），96%（72名学生中的69名）学生参与了首次评估，其中68%为女性。次年，即2013/2014学年（T2），92%（48名学生中的45名）参与；其中62%为女性，38%为男性。2014/2015学年的评估（T3）有94%（48名学生中的45名）参与。其中，67%为女性。
在评估中，学生对该课程给予了积极评价。“总体/组织”方面的问题在T1和T2的平均得分（M）为1.5（标准差=0.7），在T3为1.2（标准差=0.3）。“总体评估”的得分分别为M（T1）=1.6（标准差=0.6）、M（T2）=1.5（标准差=0.5）和M（T3）=1.1（标准差=0.3）。在T1和T2中，“教师积极让学生参与课程”这一项的平均得分是2.1（标准差=0.9），在T3中为1.2（标准差=0.5）。
这里介绍的课程从概念上展示了如何在理论和临床背景下教授实用的牙科技能。牙科专家角色的教育目标取自国家基于能力的牙科教育目标目录，也可进行补充。这些目标可应用于其他牙科学院。
