To apply problem-based learning (PBL) combined with standardized patients(SP) in during-course practice of endodontics for undergraduate dental students, in order to improve the teaching quality.
One hundred and four undergraduate dental students of China Medical University School of Stomatology were randomly divided into 2 groups, 52 students in each group. One group were taught with PBL combined with SP while the other group with lecture-based learning (LBL) alone. The teaching effect was measured with examination and questionnaire survey. The data were analyzed by Student's t test using SPSS 11.5 software package.
Students in PBL combined with SP group was better than LBL group in case analysis, didactic tests, practical tests and total scores, and there was significant difference between the two groups (P<0.05). LBL group was better than PBL combined with SP group in basic theoretical knowledge scores, and there was significant difference between the two groups (P<0.05). SP and PBL combined with SP method were welcomed by undergraduate dental students.
The abilities of undergraduate dental students can be improved by PBL combined with SP in different aspects. PBL combined with SP achieves satisfactory teaching effect, and can be applied in during-course practice of endodontics to undergraduate dental students.
将基于问题的学习（PBL）与标准化病人（SP）相结合应用于口腔医学本科学生牙髓病学课程实践中，以提高教学质量。
将中国医科大学口腔医学院104名口腔医学本科学生随机分为2组，每组52名学生。一组采用PBL与SP相结合的教学方法，另一组仅采用基于讲座的学习（LBL）。通过考试和问卷调查来衡量教学效果。使用SPSS 11.5软件包进行Student's t检验分析数据。
PBL与SP相结合组的学生在病例分析、理论测试、实践测试和总成绩方面均优于LBL组，两组间差异有统计学意义（P<0.05）。LBL组在基础理论知识得分方面优于PBL与SP相结合组，两组间差异有统计学意义（P<0.05）。标准化病人以及PBL与SP相结合的教学方法受到口腔医学本科学生的欢迎。
PBL与SP相结合可从不同方面提高口腔医学本科学生的能力。PBL与SP相结合取得了令人满意的教学效果，可应用于口腔医学本科学生牙髓病学的课程实践中。
