The aim of this study was to evaluate the effectiveness of a mobile augmented reality simulator for local anesthesia training with dental students who are administering inferior alveolar nerve block (IANB) for the first time. Participants in this prospective study conducted in 2016 were 41 fourth- and fifth-year students randomly divided into two groups: a control group with 19 students and an experimental group with 22 students. In addition to theoretical instruction and exercises, students in the experimental group used the mobile augmented reality simulator in a dental office 2h weekly for four weeks. The Sony SmartBand-2 was used to measure all students' heart rate five minutes before and during anesthesia administration. After anesthesia, students in both groups completed a post-clinical questionnaire evaluating their knowledge and skills. The experimental group had a higher average score and/or a more limited range of responses on each item of the questionnaire than the control group. The average time for performing IANB in the experimental group was 50.0±14.3 seconds, while the control group's average was 68.4±25.5 seconds. In addition, the group that used the augmented reality simulator had an anesthesia success rate of 90.9% compared to 73.7% for the control group. Students in both groups had a statistically significant increase in heart rate while performing anesthesia. Overall, the students who used the mobile simulator in addition to their education in augmented reality carried out anesthetic procedures for IANB in a shorter period of time and had greater success than the students who used only the conventional educational methods.
本研究的目的是评估一款移动增强现实模拟器对首次进行下牙槽神经阻滞（IANB）的牙科学生进行局部麻醉培训的效果。2016年进行的这项前瞻性研究的参与者为41名四、五年级学生，他们被随机分为两组：19名学生的对照组和22名学生的实验组。除了理论指导和练习外，实验组的学生每周在牙科诊所使用移动增强现实模拟器2小时，共四周。使用索尼SmartBand-2在麻醉给药前5分钟和给药期间测量所有学生的心率。麻醉后，两组学生都完成了一份临床后问卷，评估他们的知识和技能。实验组在问卷的每个项目上的平均得分更高和/或反应范围更有限。实验组进行IANB的平均时间为50.0±14.3秒，而对照组的平均时间为68.4±25.5秒。此外，使用增强现实模拟器的组的麻醉成功率为90.9%，而对照组为73.7%。两组学生在进行麻醉时心率均有统计学上的显著增加。总体而言，除了接受增强现实教育外还使用移动模拟器的学生进行IANB麻醉程序的时间更短，并且比仅使用传统教育方法的学生更成功。
