目的 研究乳牙根管治疗术Flash动画视频在临床前期实习相关教学的应用效果。方法 本研究采用试验对照方法,选择2019年5月至2019年7月参与北京大学口腔医学院儿童口腔科前期实习的2015级八年制和五年制共60名学生为研究对象,采用信封法将其随机分为试验组和对照组,每组30名学生,分别进行Flash动画视频教学和临床录制视频教学,从学生基础知识与操作要点掌握和临床前期实习操作评分2个方面进行实施效果评价。结果 基础知识与操作要点掌握上,试验组学生与对照组学生相比在总分[(4.29±0.49)分比(4.03±0.47)分]、拔髓[(4.29±0.55)分比(3.90±0.55)分]、根管预备[(4.36±0.49)分比(4.09±0.54)分]、根管充填[(4.18±0.62)分比(3.72±0.57)分]的评分均较高,其差异均具有统计学意义(均P<0.05)。试验组学生实习操作评分为(90.67±5.98)分,对照组学生为(87.00±6.90)分,其差异具有统计学意义(t=2.20,P=0.03)。结论 Flash动画视频的教学方式有助于提高学生学习效果和实习操作水平。

Objective To evaluate the application of flash animation video about pulpectomy of primary teeth in the prophase of clinical practice teaching. Methods Totally 60 students of 8-year-program and 5-year-program in undergraduates enrolled in 2015 who participated in the prophase of Pediatric Dentistry of Peking University School of Stomatology from May 2019 to July 2019 was randomly divided into the experimental group and the control group with 30 students in each. Flash animation video and clinical operation video were carried out respectively. The implementation effect was evaluated from the following two aspects: Students' mastery of basic knowledge and operation points, pre-clinical practice operation score. Results In terms of students' mastery of basic knowledge and operation points, the scores in the experimental group were higher than that in the control group [(4.29±0.49)vs(4.03±0.47)], especially in the access of the pulp[(4.29±0.55) vs (3.90±0.55)], root canal preparation[(4.36±0.49) vs (4.09±0.54)] and root canal filling[(4.18±0.62) vs (3.72±0.57)] (all P<0.05). In the evaluation for clinical operation, the students in the experimental group had the scored (90.67 ± 5.98) significantly higher than that of the control group (87.00 ± 6.90), (t=2.20,P=0.03). Conclusions The teaching assisted by flash animation video for pulpectomy of primary teeth is helpful to improve students' learning outcomes and support efficacy of skill training.
