BACKGROUND/AIM: Opportunities for dental students to obtain clinical experience in the management of traumatic dental injuries are scarce, and most dentists encounter difficulties with their first trauma patients after graduation. The aim of this study was to question students on the ease of handling of four types of flexible splints, with two common methods of bonding to the tooth.
A total of 161 fourth year dental students completed a simulated treatment of an avulsed tooth using orthodontic wire, Twistflex wire, nylon fishing line, and Powermesh as splints. The bonding materials were composite resin (Spectra ST LV) or glass ionomer cement (GC Fuji LC Ortho). The students then answered 16 questions on a 5-point Likert scale, or with an open answer field.
Most students agreed (48.8%) or strongly agreed (31.3%) that the simulated trauma exercise assisted their learning. There was strong agreement (68.8%) and agreement (28.7%) that the simulation added value to their dental training compared to didactic training only. Similarly, 52.3% of participants strongly agreed and 40% agreed that they felt engaged in the learning activity. Only 53.8% of the participants agreed and 7.5% strongly agreed that the simulation felt realistic. Most students (56.2%) found a Powermesh/composite splint was the easiest to place, and nylon fishing line/GC Fuji LC Ortho splints was the least difficult to remove (35%).
Wire-free splints with composite bonding were judged as the easiest to place by students, while glass ionomer cement was the easiest to remove.
背景/目的：牙科学生获得创伤性牙外伤管理临床经验的机会很少，大多数牙医在毕业后遇到他们的第一个外伤患者时都会遇到困难。本研究旨在询问学生处理四种弹性夹板的难易程度，这四种夹板都采用了两种常见的粘结到牙齿的方法。
共有 161 名四年级牙科学生使用正畸丝、Twistflex 丝、尼龙钓鱼线和 Powermesh 作为夹板，完成了对离体牙的模拟治疗。粘结材料为复合树脂（Spectra ST LV）或玻璃离子水门汀（GC Fuji LC Ortho）。然后，学生们在 5 点李克特量表上回答了 16 个问题，或者在开放的回答字段中回答问题。
大多数学生（48.8%）或强烈同意（31.3%）模拟创伤练习有助于他们的学习。有强烈的共识（68.8%）和协议（28.7%），模拟与单纯理论培训相比，为他们的牙科培训增加了价值。同样，52.3%的参与者强烈同意，40%的参与者同意他们对学习活动感到投入。只有 53.8%的参与者同意，7.5%的参与者强烈同意模拟感觉真实。大多数学生（56.2%）认为 Powermesh/复合夹板最容易放置，而尼龙钓鱼线/GC Fuji LC Ortho 夹板最容易去除（35%）。
学生们认为无丝夹板用复合粘结剂固定是最容易放置的，而玻璃离子水门汀是最容易去除的。
