Abstract
The aim of the study was to assess the effect of incorporation of silver nanoparticles to resin composite restorative material on its microtensile bond strength to dentin. Method: Non-carious 32 sound human molars were selected for the study.The specimens were randomly divided into two equal groups according to the silver nanoparticles incorporation. Micro tensile bond strength test was done; two representive sample of each group and analyzed using Environmental Scanning Electron Microscope (ESEM).Results: Resin composite without silver nanoparticles incorporation has the highest bond strength to deep dentin when tested after 24 hours, while resin composite without silver nanoparticles incorporation has the lowest bond strength to superficial dentin when tested after 3 months. After 3 months; resin composite specimens with incorporation of silver nanoparticles showed statistically significantly higher mean micro-tensile bond strength than resin composite specimens without incorporation of silver nanoparticles.
Conclusions: Incorporation of antibacterial silver nanoparticles to resin composite affected its bond strength to dentin that was improved with aging. The bond strength of resin composite either applied alone or with silver nanoparticles incorporation is dentin depth and aging dependent.
