Abstract:
ObjectiveTo evaluate the theoretical knowledge level of Chinese students majoring in stomatology based on the problem-based learning (PBL).MethodsThe 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.ResultsA 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.ConclusionPBL 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.
