[A survey on knowledge, attitude and practice related to evidence-based dentistry among dental students].

PURPOSE: To investigate the knowledge, attitude and practice related to evidence-based dentistry among dental students, and to provide a reference for targeted evidence-based dentistry teaching and practice evidence-based dentistry in dental students. METHODS: Dental students who attended the internship in Shanghai Ninth People's Hospital and Pudong People's Hospital were invited to attend this survey. Information on knowledge, attitude and practices related evidence-based dentistry was collected through questionnaires. SPSS 21.0 software package was used for data analysis. RESULTS: A total of 62 dental students attended this survey. Evidence-based dentistry related knowledge and attitude scores were 5.5±1.9 and 5.1±1.0, respectively. Over three quarters of students took courses on evidence-based medicine, while around half of students (56.5%) self-reported that they knew little about evidence-based medicine. 70.5% students practiced evidence-based dentistry less than once in the process of clinical decision making per week. The majority of students (80.3%) used MEDLINE or other databases to search for practice-related literature less than once per week. 63.9% students used practice guideline. The top three barriers to practice evidence-based dentistry were lack of information resources, insufficient time and lack of search skills. CONCLUSIONS: Evidence-based dentistry related knowledge and practice among dental students is deficient, whereas they hold positive attitude on practice. The top three barriers to practice evidence-based dentistry are lack of information resources, insufficient time and lack of search skills.
