Abstract

Background: Endodontic microsurgery (EMS), indicated to manage teeth unresponsive to conventional root canal treatment, requires advanced technical expertise and clinical judgement. Traditional pre-clinical training methods lack fidelity and fail to replicate diseased states, leading to a steep learning curve clinically. High-fidelity 3D jaw model simulations offer a realistic and repeatable training solution, bridging the gap between theory and clinical practice.

Aim: To evaluate the effectiveness of high-fidelity 3D jaw model simulations in enhancing residents' confidence and preparedness for endodontic microsurgery.

Methodology: A descriptive cross-sectional study was conducted involving second-year Endodontic residents enrolled in a postgraduate programme at the National University of Singapore. The intervention group (n = 11; 2021-2023 cohorts) participated in a structured four-session simulation training using high-fidelity 3D jaw models replicating anatomical details and periapical pathology. The curriculum incorporated diverse clinical scenarios, deliberate practice, and structured feedback. The control group (n = 4; 2020 cohort) attended a single-session workshop using pig mandibles. Pre- and post-workshop questionnaires were administered to assess self-reported confidence and preparedness using questions adapted from the Simulation Design Scale (SDS) and the Student Satisfaction and Self-Confidence in Learning (SSSCL) scale. Residents also completed a post-surgical evaluation after their first EMS procedure.

Results: Residents trained with 3D models demonstrated greater improvements across all domains. Confidence in treatment planning improved from 2.45 ± 0.93 to 3.68 ± 0.69, compared to 3.75 ± 0.50 to 4.00 ± 0.00 in controls. Preparedness for EMS increased from 1.54 ± 0.82 to 3.20 ± 0.91 in the 3D group, and from 2.00 ± 0.82 to 2.75 ± 0.96 in the control group. Confidence in independently performing EMS rose from 1.27 ± 0.47 to 3.03 ± 0.95 in the 3D group, compared to 2.25 ± 0.82 to 3.00 ± 0.82 in the control group. The 3D group reported higher ratings for simulation realism, reduced stress, and greater perceived preparedness for clinical EMS.

Conclusion: High-fidelity 3D jaw model simulations were effective in improving residents' confidence and preparedness for EMS. These findings support the integration of 3D simulation into Endodontic training to enhance clinical readiness and surgical competence.

高保真三维颌模型模拟在加强牙髓显微外科训练中的效果。
背景:牙髓显微手术(Endodontic microsurgery, EMS)用于治疗对传统根管治疗无反应的牙齿,需要先进的专业技术和临床判断。传统的临床前训练方法缺乏保真度,无法复制病变状态,导致临床学习曲线陡峭。高保真三维颌模型模拟提供了一个现实的和可重复的训练解决方案,弥合理论和临床实践之间的差距。目的:评价高保真度三维颌模型模拟在提高居民对牙髓显微手术的信心和准备方面的有效性。方法:一项描述性横断面研究涉及在新加坡国立大学就读研究生课程的牙髓学二年级住院医师。干预组(n = 11; 2021-2023队列)使用高保真3D颌骨模型复制解剖细节和根尖周病理,参加了结构化的四次模拟训练。课程包括不同的临床场景、刻意练习和结构化反馈。对照组(n = 4; 2020队列)参加了一个使用猪下颌骨的单次研讨会。使用模拟设计量表(SDS)和学生学习满意度和自信心量表(SSSCL)的问题,对研讨会前和研讨会后的问卷进行评估,以评估自我报告的信心和准备情况。住院医师在第一次EMS手术后也完成了术后评估。结果:接受3D模型培训的住院医生在所有领域都表现出更大的进步。治疗计划的置信度从2.45±0.93提高到3.68±0.69,对照组为3.75±0.50至4.00±0.00。3D组的EMS准备度从1.54±0.82提高到3.20±0.91,对照组从2.00±0.82提高到2.75±0.96。3D组独立执行EMS的信心从1.27±0.47上升到3.03±0.95,而对照组从2.25±0.82上升到3.00±0.82。3D组报告了更高的模拟真实性评分,减少了压力,并对临床EMS有了更好的准备。结论:高保真度三维颌部模型模拟能有效提高居民对EMS的信心和准备。这些发现支持将3D模拟整合到牙髓训练中,以提高临床准备和手术能力。

期刊介绍: The International Endodontic Journal is published monthly and strives to publish original articles of the highest quality to disseminate scientific and clinical knowledge; all manuscripts are subjected to peer review. Original scientific articles are published in the areas of biomedical science, applied materials science, bioengineering, epidemiology and social science relevant to endodontic disease and its management, and to the restoration of root-treated teeth. In addition, review articles, reports of clinical cases, book reviews, summaries and abstracts of scientific meetings and news items are accepted. The International Endodontic Journal is essential reading for general dental practitioners, specialist endodontists, research, scientists and dental teachers.
