: Preclinical dental training requires simulation-based tools to develop fine motor skills, but traditional models like plastic teeth often lack realistic tactile feedback, and systematic evaluations of multi-layered drilling plates are scarce. This study aimed to evaluate the educational utility and perceived realism of a novel multi-layered drilling plate designed to simulate enamel, dentin, and pulp, with null hypotheses that it would not differ in realism from natural dental tissues or in educational utility from existing tools. : Seventy dental educators (mean preclinical teaching experience: 112.9 ± 116.7 months) from 14 institutions across four continents assessed the plates using standardized protocols. Statistical analysis (Mann-Whitney U Test) was performed to analyze the results. : Quantitative ratings (1-10 scale) showed high mean scores for drilling quality (enamel: 7.80 ± 1.55, dentin: 7.27 ± 1.94, pulp: 7.48 ± 2.33), surface smoothness (enamel: 8.17 ± 1.55, dentin: 8.17 ± 1.57), and ergonomic visibility (8.56 ± 1.58), with 90% passing grades, rejecting the null hypothesis of no difference in educational utility. Tissue transition scores (enamel/dentin: 7.09 ± 2.56; dentin/pulp: 6.86 ± 2.46) showed significant differences ( < 0.05) in realism from natural tissues, rejecting the null hypothesis of no difference. Inter-rater reliability was poor (Krippendorff's alpha: 0.449 for failing scores, 0.211 for passing scores). Qualitative feedback praised ease of use but noted limitations in dentin haptic simulation. : The drilling plate shows promise for skill development, though without controlled comparisons to existing tools, its relative efficacy remains preliminary. Further research on student outcomes and tool refinement is needed to validate its use in dental education.
临床前牙科培训需要基于模拟的工具来培养精细运动技能，但像塑料牙齿这样的传统模型往往缺乏逼真的触觉反馈，而且对多层钻孔板的系统评估也很少。本研究旨在评估一种新型多层钻孔板的教育效用和感知逼真度，该钻孔板旨在模拟牙釉质、牙本质和牙髓，其零假设是它在逼真度上与天然牙齿组织没有差异，在教育效用上与现有工具没有差异。来自四大洲14个机构的70名牙科教育工作者（临床前教学平均经验：112.9 ± 116.7个月）使用标准化方案对这些钻孔板进行了评估。进行了统计分析（曼-惠特尼U检验）以分析结果。定量评分（1 - 10分制）显示钻孔质量（牙釉质：7.80 ± 1.55，牙本质：7.27 ± 1.94，牙髓：7.48 ± 2.33）、表面光滑度（牙釉质：8.17 ± 1.55，牙本质：8.17 ± 1.57）和人体工程学可视性（8.56 ± 1.58）的平均得分较高，及格率为90%，拒绝了教育效用无差异的零假设。组织过渡评分（牙釉质/牙本质：7.09 ± 2.56；牙本质/牙髓：6.86 ± 2.46）显示与天然组织在逼真度上存在显著差异（<0.05），拒绝了无差异的零假设。评分者间信度较差（克里彭多夫阿尔法系数：不及格分数为0.449，及格分数为0.211）。定性反馈称赞了其易用性，但指出了牙本质触觉模拟方面的局限性。该钻孔板在技能培养方面显示出前景，不过由于没有与现有工具进行对照比较，其相对功效仍属初步。需要对学生的学习成果和工具改进进行进一步研究，以验证其在牙科教育中的应用。
