To assess whether the implementation of teeth drawing exercises in a dental anatomy course improves first-year (D1) dental students' understanding of tooth morphology, their dexterity, and their clinical skills compared with D1s who did not participate in the drawing exercises.
In 2020, a "Teeth Drawing Module" was implemented within the D1 dental anatomy curriculum. In this course, students learn how to draw accurate outlines of teeth. The students are required to complete two types of drawing projects. Illustrations and instructions of teeth drawings that are outlined in a manual drawing book, PowerPoint presentations, illustration videos, and assessments are provided. Students' grades in the drawing module, waxing skills assessments, and their didactic exams were used to evaluate and assess the correlation between their drawing aptitude and their manual skills. Students who took the drawing course were compared with students who did not take the drawing course to determine if the drawings improved students' understanding of tooth morphology, their dexterity, and their clinical skills. A comprehensive survey was also developed and distributed to students who had the drawing module in their curriculum.
Students who participated in the drawing module were more successful in the dental anatomy course compared with students in the control classes. Classes that had drawing exercises scored significantly higher in all dental anatomy waxing exercises compared with classes that did not have drawing exercises ( < 0.001). There was a significant positive correlation between drawing and waxing scores ( < 0.05). Moreover, there was a significant positive correlation between drawing and didactic scores ( < 0.001).
Drawing exercises can be useful instruments for effectively representing and integrating the spatial domain of anatomical information. Teeth drawings as an adjunctive tool offer excellent visualization and allow students to improve their manual dexterity and knowledge in the dental anatomy course.
评估在牙科解剖学课程中实施牙齿绘图练习是否比未参加绘图练习的一年级牙科学生（D1）能更好地提高他们对牙齿形态的理解、灵活性和临床技能。
2020年，在D1牙科解剖学课程中实施了一个“牙齿绘图模块”。在本课程中，学生学习如何绘制准确的牙齿轮廓。学生需要完成两种类型的绘图项目。提供了手绘图书中概述的牙齿绘图的插图和说明、PowerPoint演示文稿、插图视频及评估。学生在绘图模块中的成绩、蜡型制作技能评估以及理论考试成绩被用于评估和分析他们的绘图能力与手工技能之间的相关性。将参加绘图课程的学生与未参加绘图课程的学生进行比较，以确定绘图是否提高了学生对牙齿形态的理解、灵活性和临床技能。还开发了一份综合调查问卷并分发给课程中有绘图模块的学生。
与对照班级的学生相比，参加绘图模块的学生在牙科解剖学课程中表现更出色。与没有绘图练习的班级相比，进行绘图练习的班级在所有牙科解剖学蜡型制作练习中的得分显著更高（<0.001）。绘图成绩与蜡型制作成绩之间存在显著正相关（<0.05）。此外，绘图成绩与理论成绩之间也存在显著正相关（<0.001）。
绘图练习可以成为有效呈现和整合解剖学信息空间领域的有用工具。牙齿绘图作为一种辅助工具具有出色的可视化效果，能让学生在牙科解剖学课程中提高手工灵活性和知识水平。
