不同饮料致牙釉质脱矿的原子力显微镜实验教学设计

Experimental Teaching Design Based on Atomic Force Microscope for Enamel Demineralization Induced by Different Beverages

为满足口腔医学临床教学实验与大型设备检测教学相结合的需求,将原子力显微技术应用到牙釉质脱矿评价的实验教学设计中。此实验涉及临床和大型仪器设备等多个理论基础知识,系统地训练了学生资料查阅、实验设计、仪器使用、实验操作与分析的能力。实验中选取青少年喜欢的几种不同种类的饮料展开对牙釉质的脱矿研究,不仅贴近实际生活,而且结合学生的专业背景知识,激发其研究兴趣,加强其科学素养以及培养创新能力。此外,学生可对实验进行自主设计、探索与延伸,培养其科学研究兴趣与实践的能力,增强创新意识,可应用于开放式实验教学中。

In order to meet the needs of the conbination of oral clinical medicine teaching and large equipment testing teaching,atomic force microscopy was applied to the expetimental teaching design of enamel demineralization evaluation. This experiment involves a lot of basic theoretical knowledge based on clinical medicine and large-scale equipment and so on. As a result, students’ abilities of data access, experimental design, instrument using, experimental operation and analysis have been systematically trained.In the experiment, different beverages favored by teenagers are selected to carry out the enamel demineralization research, which is not only close to the real life, but is combined with students’ professional knowledge, which can stimulate students’ research interest,strengthen their scientific literacy and cultivate their innovation ability. Additionally, the experiment can be designed, explored and extended independently by students to cultivate their scientific research interest and practice ability, enhance their innovation awareness, being applied in open experimental teaching.
