Tooth-colored dental resins are widely used. Dental resins divide broadly into two categories: Chemical-curing type and light-curing type. In this chapter, we discuss the photochemistry in dentistry such as several sorts of curing system and reaction. In order to understand resin materials for dental purposes, two main points have to be concerned: One is "adhesion" or "bonding" to tooth substrates, and the other is "curing" for setting of resin-based materials. Dental resins themselves do not provide bonding ability to tooth substrates; tooth-colored dental resins need additional adhesives before dental resin filling. Without setting through polymerization of dental monomers, resin-based materials cannot stably exist in a severe oral condition. Insufficient polymerization causes dental resin degradation and secondary caries. In order to improve polymerization, initiators for curing and curing devices have been developed to improve polymerization. Therefore, at first the structure of tooth is explained in brief to understand "adhesion" to tooth substrates, enamel and dentin. Then, the history of the development of tooth-colored dental resins and adhesive resins is then introduced. Next, curing systems used in dental resin materials are explained. Moreover, toxicity of dental resin and future research opportunities are included.
