Abstract:
Light-curing parameters are critical determinants of the degree of monomer conversion, mechanical properties, and color stability in composite resins. Currently, light-curing technology is evolving toward multi-mode, multi-peak wavelength, and intelligent programmed irradiation, while the photoinitiator systems of resins are transitioning from traditional camphorquinone/amine to novel amine-free systems, resulting in significantly varied responses of different materials to curing parameters. This review summarizes the comprehensive effects of light-curing parameters on the polymerization performance and long-term stability of composite resins, with a focus on the applicable boundaries of the exposure reciprocity law (ERL), the differentiated responses of various photoinitiator systems, and the potential correlation between radiant energy and color stability, aiming to provide evidence-based guidance for the precise matching of clinical light-curing protocols.
