Abstract

This activity report describes a novel pedagogical approach to teach undergraduate dentistry students about the degree of conversion of dental resin-based composites (RBCs) using Fourier Transform Infrared (FTIR) spectroscopy. Six final-year dentistry students participated in a hands-on laboratory exercise where they prepared RBC samples, collected FTIR spectra before and after polymerization, and calculated the degree of conversion using the obtained data. The activity aimed to bridge the gap between theoretical knowledge and practical application, allowing students to better understand this important concept in dental materials science. Participants found the exercise engaging, informative, and valuable for future professional practice. The activity successfully reinforced students’ comprehension of the degree of conversion process and provided them with hands-on experience in using analytical techniques to characterize dental materials. This approach demonstrates the feasibility and benefits of incorporating advanced characterization methods into undergraduate dentistry curricula, enhancing students’ technical skills and scientific understanding.

用FTIR光谱法测定牙用树脂复合材料（活性）的转化度

本活动报告描述了一种新颖的教学方法，用于教授牙科本科生使用傅里叶变换红外（FTIR）光谱对牙科树脂基复合材料（rbc）的转化程度。六名牙科专业的大四学生参加了一项动手实验，他们准备了RBC样品，收集了聚合前后的FTIR光谱，并使用获得的数据计算了转化程度。该活动旨在弥合理论知识与实际应用之间的差距，让学生更好地理解牙科材料科学中的这一重要概念。参与者发现这个练习很有吸引力，内容丰富，对未来的专业实践很有价值。该活动成功地加强了学生对转化程度过程的理解，并为他们提供了使用分析技术表征牙科材料的实践经验。这种方法证明了将先进的表征方法纳入本科牙科课程的可行性和益处，提高了学生的技术技能和科学理解。

期刊介绍： The Journal of Chemical Education is the official journal of the Division of Chemical Education of the American Chemical Society, co-published with the American Chemical Society Publications Division. Launched in 1924, the Journal of Chemical Education is the world’s premier chemical education journal. The Journal publishes peer-reviewed articles and related information as a resource to those in the field of chemical education and to those institutions that serve them. JCE typically addresses chemical content, activities, laboratory experiments, instructional methods, and pedagogies. The Journal serves as a means of communication among people across the world who are interested in the teaching and learning of chemistry. This includes instructors of chemistry from middle school through graduate school, professional staff who support these teaching activities, as well as some scientists in commerce, industry, and government.
