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.

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.
