Abstract
To evaluate the effect of chlorhexidine and Sodium hypochlorite pretreatment on
the in vivo durability of bonded Nano-filled resin composite restorations to
different dentin depths as assessed by silver deposition as an indication of
nanoleakage level of the adhesive systems over 24 hours and three months using Environmental Scanning Electron Microscope (ESEM) and the EDAX (energy
dispersive analytical x-ray).
