Abstract
Resin cements are an important factor that affects the mechanical and esthetic success of indirect dental restorations. Their performance can be negatively affected by aging processes that compromise the shear bond strength and color stability over time. The aim of this narrative review is to discuss the effects of different aging methods on the shear bond strength and color stability of resin cements, particularly the types with a color cleanup indicator. Various aging methods, such as thermocycling, water storage, and ultraviolet exposure, have been used to simulate clinical conditions. Most studies reported a decrease in shear bond due to hydrolytic degradation. Similarly, in color stability, discoloration occurs over time due to changes in the material’s intrinsic composition and external factors. Color cleanup indicators have been added to help remove excess cement, but their impact on long-term mechanical and optical properties remains debated; more studies are needed to study their actual effect. A standardized aging protocol and longer-term clinical studies will help to assess their effect in resin cements.
