AIM To evaluate and compare the feedback of final year undergraduate dental students in eight Malaysian dental schools on the application of a new system for classifying root canal morphology in teaching and clinical practice. METHODS One PowerPoint presentation describing two classification systems for root canal morphology (Oral Surgery Oral Medicine Oral Pathology, 1974 38, 456 and its supplemental configurations, International Endodontic Journal 2017, 50, 761) was delivered to final year undergraduate dental students in eight dental schools in Malaysia by two presenters (each presented to four schools). To examine students' feedback on the utility of each system, printed questionnaires consisting of six questions (five multiple choice questions and one open-ended question) were distributed and collected after the lecture. The questionnaire was designed to compare the classification systems in terms of accuracy, practicability, understanding of root canal morphology and recommendation for use in pre-clinical and clinical courses. The exact test was used for statistical analysis, with the level of significance set at 0.05 (P = 0.05). RESULTS A total of 382 (out of 447) students participated giving a response rate of 86%. More than 90% of students reported that the new system was more accurate and more practical compared with the Vertucci system (P < 0.001). Overall, 97% of students reported the new system helped their understanding of root and canal morphology compared with the Vertucci classification (P < 0.001). Over 97% of students recommended the use of the new system in teaching, pre-clinical courses and clinical practice (P < 0.001). Except for two schools, no significant difference was detected between the responses of students for all questions at the different schools (P > 0.05). The students' responses for all questions were almost similar for both presenters (P > 0.05). CONCLUSIONS The new system of International Endodontic Journal 2017, 50, 761 for classifying root and canal morphology was favoured by final year undergraduate dental students in Malaysia. The new system has the potential to be included in the undergraduate endodontic curriculum for teaching courses related to root and canal morphology.

一种用于对根管形态进行分类的新系统在大学教学和临床实践中的应用：马来西亚的一项全国调查。

目的评估和比较马来西亚八所牙科学校最后一年的本科牙科学生对在教学和临床实践中应用新的根管形态分类系统的应用的反馈。方法向八所牙科学校的最后一年的本科口腔医学专业学生提供了一个PowerPoint演示文稿，描述了两种针对根管形态的分类系统（口腔外科口腔医学口腔病理学，1974年38、456及其补充配置，国际牙髓杂志2017、50、761）在马来西亚由两名主持人介绍（每人向四所学校颁奖）。为了检查学生对每个系统的效用的反馈，在讲座后分发并收集了由六个问题（五个选择题和一个开放性问题）组成的印刷调查表。该问卷旨在比较分类系统的准确性，实用性，对根管形态的了解以及在临床前和临床课程中的使用建议。精确检验用于统计学分析，显着性水平设置为0.05（P = 0.05）。结果共有382名学生（共447名）参加了调查，回答率为86％。超过90％的学生报告说，与Vertucci系统相比，新系统更准确，更实用（P <0.001）。总体而言，与Vertucci分类法相比，有97％的学生报告说新系统有助于他们对牙根和根管形态的理解（P <0.001）。超过97％的学生建议在教学，临床前课程和临床实践中使用新系统（P <0.001）。除两所学校外，不同学校对所有问题的学生回答之间均未发现显着差异（P> 0.05）。两位演讲者对学生所有问题的回答几乎相似（P> 0.05）。结论国际上牙髓学杂志2017、50、761的新系统可以对牙根和根管的形态进行分类，受到了马来西亚牙科学专业的本科生的青睐。该新系统有可能被纳入牙髓牙髓课程中，以教授与根管形态有关的课程。结论新的国际牙髓学杂志2017、50、761对牙根和根管形态进行分类的新系统受到马来西亚大学预科本科生的青睐。该新系统有可能被包括在牙髓学课程中，以教授与根管形态有关的课程。结论新的国际牙髓学杂志2017、50、761对牙根和根管形态进行分类的新系统受到马来西亚大学预科本科生的青睐。该新系统有可能被纳入牙髓牙髓课程中，以教授与根管形态有关的课程。
