目的评价以问题为基础的学习(Problem-based learning,PBL)对国内口腔医学生理论成绩的影响.方法采用Cochrane系统评价的方法,计算机和手工方法检索1989 - 2010年国内PBL教学和传统教学应用于口腔医学教学的随机对照研究.在严格筛选资料和质量评价的基础上,采用RevMan 5.0.1软件对纳入的研究进行Meta分析.结果共检索到138篇相关文献,最终有8篇文献符合纳入标准.因研究间差异具有统计学意义(P＜0.01,I2=80％),采用随机效应模型进行Meta分析,[MD 5.39,95％ CI(2.20,8.58)].结论 PBL教学对国内口腔医学生理论成绩的提高有促进作用.

Objective To evaluate the theoretical knowledge level of Chinese students majoring in stomatology based on the problem-based learning (PBL).Methods The Cochrane reviewer's handbook was followed by.Domestic published articles from 1989 -2010 were selected by computer and handwork.All these retrieved studies were controlled clinical trials related to oral theoretical education and were conducted by PBL and the traditional teaching methods.The quality of included studies was critically evaluated and the data were analyzed by the RevMan 5.0.1 software.Results A total of 138 articles were selected,but only 8 were included.Significant differences were found when the data were pooled(P ＜ 0.01,I2 =80％ ) and random effect model was used for meta-analysis.The results showed that comparing with the traditional teaching methods,PBL can improve the theoretical score of dental students [ MD 5.39,95％ CI(2.20,8.58)],and sensitivity analysis showed that the result was stable.Conclusion PBL can improve the theoretical score of Chinese students majoring in stomatology.However,as part of the studies are not high quality literature,the above conclusion needs to be verified by more large sample-sized,rigorously designed randomized controlled clinical trials.
