PURPOSE/OBJECTIVES: To assess student perceptions on learning dental anatomy using natural extracted teeth, 3D printed models, 3D virtual models, and augmented reality (AR) technology. METHODS: Eighty first-year dental students enrolled in the dental anatomy course were instructed to examine four stations. The stations included four versions of a mandibular first molar: an extracted natural tooth, a 3D printed model, a 3D virtual model, and a model displayed on a novel AR device. After examining all stations, the students were asked to complete an electronic survey. Bivariate analysis was performed to determine whether students' perceptions are related to their demographic characteristics and technological experience with computer use, 3D modeling, and video games. RESULTS: Seventy students completed the survey (87.5% response rate). Students rated natural teeth to have the highest educational value, the 3D printed tooth to be the most accessible, and the AR application to be the most interesting modality. Students who played little to no video games were more likely to rate AR as high educational value (48.8% vs. 10.3%; p < 0.001), while students with little 3D modeling experience were more likely to rate high accessibility of the 3D Model (78.1% vs. 48.3%; p < 0.001). No statistically significant associations between the perceptions and students' demographic characteristics or use of computer were noted.
The natural extracted tooth was rated highest in educational value, while the 3D printed model was rated easiest to use, and the AR model was the most interesting to the students.
目的/目标：评估学生对使用天然提取牙、3D 打印模型、3D 虚拟模型和增强现实 (AR) 技术学习牙科解剖学的看法。方法：80 名一年级牙科学生参加了牙科解剖学课程，他们被指导检查四个站点。这些站点包括下颌第一磨牙的四个版本：天然提取牙、3D 打印模型、3D 虚拟模型和新型 AR 设备上显示的模型。检查完所有站点后，学生被要求完成电子调查。进行了双变量分析，以确定学生的看法是否与他们的人口统计学特征以及他们对计算机使用、3D 建模和视频游戏的技术经验有关。结果：70 名学生完成了调查（87.5%的回应率）。学生认为天然牙齿具有最高的教育价值，3D 打印牙齿最容易获得，而 AR 应用程序最有趣。很少或不玩视频游戏的学生更有可能将 AR 评为高教育价值（48.8%比 10.3%；p<0.001），而 3D 建模经验较少的学生则更有可能将 3D 模型的高可访问性评为高（78.1%比 48.3%；p<0.001）。学生的人口统计学特征或计算机使用与看法之间没有显著的关联。结论：天然提取牙在教育价值方面被评为最高，而 3D 打印模型在易用性方面被评为最高，AR 模型对学生来说最有趣。
