RESUMO
Objective:To explore the application effect of flipped classroom model based on Simodont dental training system in the standardized training teaching of prosthodontics.Methods:The control experiment was used in this study. Seventy two students from Batch 2018 and Batch 2019 of Stomatology Hospital of Air Force Medical University were selected and randomly divided into experimental group (flipped classroom model based on Simodont dental training system) and control group (Simodont dental training system training mode after traditional teaching), with 18 students every academic year in each group. Questionnaire survey was conducted to evaluate the teaching effect, and the results of after-class theory test and practical computer test were compared between the two groups. SPSS 20.0 was used for chi-square test and t test. Results:The experimental group was better than the control group in enhancing classroom interest, improving the ability of independent analysis and problem-solving, and cultivating the ability of cooperation and expression ( P<0.05). The scores of after-class theory test and practical computer test in the experimental group [(23.36±0.21) points and (90.56±0.52) points] were significantly better than those in the control group[(21.81±0.25) points and (88.31±0.48) points] ( P<0.01). Conclusion:The flipped classroom model based on Simodont dental training system can effectively improve the effect of standardized training and teaching of professional skills in prosthodontics. At the same time, the students' ability of independent analysis and problem solving, cooperation and communication and expression are effectively improved.
RESUMO
Objective:To explore the application of the Simodont dental trainer in preclinical manual dexterity training for dental students of different grades, and to discuss its effect by quantitatively evaluating their practice results.Methods:The evaluation was conducted among 118 students in the Department of Stomatology, Shantou University Medical College from Batch 2015 to Batch 2018. Each student had five different manual dexterity modules for training. Each module had three levels of difficulty and was required to be completed in 30 minutes. The assessment index included Target, Leeway Bottom and Sides, Container Bottom and Sides, which was provided by the Simodont dental trainer. The operating time (in seconds), the displacement of the dental hand pieces and the dental mirrors (in meters) were simultaneously recorded. SPSS 25.0 was used for statistical analysis.Results:For the index Target, Leeway Bottom and Sides, Container Bottom and Sides, the results showed that there was a statistical difference between students who passed pre-clinical training and who did not take the professional course ( P < 0.001). For the index Target, differences were showed among students from different grades in all modules ( P < 0.001). Conclusion:The circle module, channel module, hollow-circle module and cross-module in the Simodont dental trainer have sensitivity to discriminate the manual dexterity of different levels of dental students. The further assessment of the discrimination of the manual dexterity is required for assume-block module. The Simodont dental trainer can quantitatively measure the manual dexterity of dental students, which is important for the quantitative evaluation of dental preclinical education.
