Abstract
To attain the correct polymerization of the resin cements, which results in improved physical qualities of the cement, dentists primarily utilize dual-cured or light-cured resin cements. However, a number of factors can influence how resin cements polymerize. A scoping review of the polymerization, degree of conversion (DC), and light transmittance of various resin cements used in dentistry was the primary goal of the current study. Nevertheless, thick restorations and deep preparations may reduce light intensity, leading to insufficient polymerization. The luting resin polymerization and its study are also influenced by other elements such as the kind, composition, and shade of the resin cement; the type, shade, and translucency of the ceramic; the light curing unit (LCU); and the testing technique. The mechanical and biological qualities of the luting cement, the mechanical properties of bound ceramics, and the strength of the bond between the tooth and restoration could all be negatively impacted by inadequate polymerization. Thus, several light-curing characteristics, including sufficient light distance, irradiance, exposure time, equipment, and wavelength, should be taken into consideration when optimizing the polymerization of resin cements. After that, the cemented restorative materials’ ideal physical characteristics are attained, resulting in long-term clinical performance.
