This is a global study that evaluated the undergraduate endodontic curriculum in dental schools worldwide. An online questionnaire sent to faculty members involved in undergraduate endodontic teaching at 50 dental institutions across six continents. The questionnaire was a modified version of previously validated survey comprised of 46 questions in three sections on essential aspects of the didactic, preclinical (PT), clinical trainings (CT), and assessments in undergraduate endodontic programs. The response rate was 76%. 63.2% of schools have a separate preclinical course, with 65.8% having a dedicated clinical area. Traditional methods dominate, with 84.2% using phantom heads and 78.9% using natural extracted teeth. The student-to-staff ratio for clinical training ranges from 1:6 to 1:9, with most supervisors specializing in endodontics (76.3%). Lectures and practical sessions are the primary teaching methods. Non-surgical root canal treatment (RCT) is the most common procedure (94.7%), and the majority use stainless steel or rotary nickel-titanium files. Cold lateral compaction is the preferred obturation technique globally (81.6%), except in North America. Advanced technologies like magnifying systems and ultrasonic instruments are rarely used in training. The conclusion emphasizes the need for global standardization and adoption of modern techniques to enhance the quality of endodontic education and care.
这是一项全球性研究，评估了世界各地牙科学院的本科牙髓病学课程。向六大洲50所牙科机构中参与本科牙髓病学教学的教员发送了一份在线问卷。该问卷是先前经过验证的调查问卷的修改版，由46个问题组成，分为三个部分，涉及本科牙髓病学课程的理论教学、临床前培训（PT）、临床培训（CT）以及评估的基本方面。回复率为76%。63.2%的学校设有单独的临床前课程，65.8%的学校设有专门的临床区域。传统方法占主导地位，84.2%的学校使用仿头模型，78.9%的学校使用天然拔除牙。临床培训的师生比为1:6至1:9，大多数督导员专门从事牙髓病学（76.3%）。讲座和实践课程是主要的教学方法。非手术根管治疗（RCT）是最常见的操作（94.7%），大多数使用不锈钢或旋转镍钛锉。除北美外，冷侧向加压是全球首选的充填技术（81.6%）。放大系统和超声器械等先进技术在培训中很少使用。结论强调需要全球标准化并采用现代技术，以提高牙髓病学教育和治疗的质量。
