Abstract：
Artificial teeth in dental training have become a valuable tool for students to gain hands-on experience in a safe and controlled environment. This training method allows students to practice various dental procedures and develop their skills without putting patients at risk. Artificial teeth can be used to simulate dental conditions, allowing students to gain experience in dealing with various situations and techniques. Although previous studies in human dentistry have demonstrated the feasibility of using 3D-printed teeth for teaching endodontic procedures such as root canal therapy, similar research has yet to be conducted in the veterinary field. This study aimed to assess the feasibility of creating 3D-printed teeth from an adult dog skull and validate their use as an alternative training tool for root canal therapy in this species. For this, cone beam computed tomography images from a medium-sized dog skull were used to replicate its teeth using a digital 3D printing system. Then, artificial mandibular first molar teeth and a 24-question survey were sent to specialized veterinary dentistry practitioners in Brazil to assess their perception of the model\'s characteristics during endodontic treatment. In conclusion, it was feasible to create 3D-printed models of dog teeth with high accuracy for the endodontic system. Despite the differences in the properties of the two materials between natural and artificial teeth, it was possible to use the artificial tooth as a training device for conventional endodontic treatment in dogs. The reliability level for the survey was reported as good, displaying a reliability coefficient above 0.86.
摘要：
牙科培训中的人造牙齿已成为学生在安全和受控的环境中获得实践经验的宝贵工具。这种培训方法使学生能够练习各种牙科程序并发展他们的技能，而不会使患者处于危险之中。人造牙齿可以用来模拟牙齿状况,让学生获得处理各种情况和技巧的经验。尽管人类牙科的先前研究已经证明了使用3D打印牙齿进行根管治疗等牙髓手术的可行性。在兽医领域还没有进行类似的研究。这项研究旨在评估从成年狗头骨创建3D打印牙齿的可行性，并验证它们作为该物种根管治疗的替代训练工具的用途。为此，使用数字3D打印系统，使用中型狗头骨的锥形束计算机断层扫描图像来复制其牙齿。然后，人工下颌第一磨牙和24个问题的调查被发送给巴西的专业兽医牙科医师，以评估他们在牙髓治疗期间对模型特征的感知。总之,为牙髓系统创建高精度的3D打印狗牙模型是可行的。尽管两种材料的性质在天然和人造牙齿之间存在差异，可以将人造牙齿用作狗的常规牙髓治疗的训练设备。调查的可靠性水平报告为良好，显示高于0.86的可靠性系数。
