To compare the effectiveness of administering inferior alveolar nerve blocks (IANB) for the first time with or without a previous practical lesson using a simple manufactured simulator.
This was a study designed to compare students' first administration of IANB anesthesia during 2022, with or without a previous practical lesson. Students were randomized into two groups. The experimental group attended both theoretical lessons and a practical lesson with a simulator device, while the control group attended only theoretical lessons. The theoretical lesson included usual contents such as anatomy, physiology, technical maneuvers for administering anesthesia, tips, and complications, and the practical lesson consisted of the administration of anesthesia using a simple manufactured simulator. After students applied their first IANB, its efficacy, and their answers to a questionnaire on a 5-point Likert scale were recorded. Statistical analysis consisted of the Chi-square test (p < 0.05).
The study recorded 60 anonymous surveys. The main difference observed was in instrument handing (p < 0.05), and there was a tendency in the ease of recognition of the anatomical marks used for the technique-pterygomandibular raphe and coronoid notch of the mandible (p = 0.08 and 0.11, respectively). No difference in success was observed (p > 0.05). Self-confidence and personal feelings did not differ statistically. All students agreed strongly or partially that training with the simulator model was helpful.
Students who used simple manufactured simulators achieved better outcomes for instrument handling, and possibly for identification of anatomical landmarks, than those who received only theoretical lessons.
比较首次使用简易自制模拟器进行下牙槽神经阻滞（IANB）操作时，有无之前的实践课程对操作效果的影响。
本研究旨在比较2022年学生首次进行IANB麻醉时，有无之前实践课程的情况。学生被随机分为两组。实验组参加理论课程和使用模拟器设备的实践课程，而对照组仅参加理论课程。理论课程包括解剖学、生理学、麻醉给药技术操作、技巧和并发症等常规内容，实践课程包括使用简易自制模拟器进行麻醉给药。学生首次进行IANB操作后，记录其操作效果以及他们对一份5级李克特量表问卷的回答。统计分析采用卡方检验（p < 0.05）。
该研究记录了60份匿名调查。观察到的主要差异在于器械操作（p < 0.05），并且在识别用于该技术的解剖标志——翼下颌韧带和下颌骨冠突切迹方面存在一定趋势（分别为p = 0.08和0.11）。在成功率方面未观察到差异（p > 0.05）。自信心和个人感受在统计学上没有差异。所有学生都强烈或部分认同使用模拟器模型进行训练是有帮助的。
与仅接受理论课程的学生相比，使用简易自制模拟器的学生在器械操作方面取得了更好的效果，在识别解剖标志方面可能也更好。
