Degradation of optical and surface properties of resin-based composites with distinct nanoparticle sizes but equivalent surface area

Conclusion The optical properties of the tested materials were not dependent of the fillers’ surface area, while the surface properties were. Clinical significance Several factors influence the ageing resistance of the resin-based composites, including the surface area of the fillers and the amount and coupling treatment of them. The improvement of the material’s physical stability could avoid the premature replacement of dental restorations.
