Introduction:
Secondary caries at the restorative margins is the common reason for dental composite restoration failure. Our objectives were to evaluate the anti-caries activity of new generation rechargeable composites and to evaluate three different concentrations of quaternary ammonium methacrylate compound on
Material and Methods:
The composite resin consisted of urethane dimethacrylate and triethylene glycol divinylbenzyl ether and was prepared with 2%, 5%, and 8% of dimethylaminohexadecyl methacrylate (DMAHDM) and 20% of nanoparticles of amorphous calcium phosphate for remineralization.
Result:
It was found that the incorporation of 8% DMAHDM significantly reduced
Concusion:
Hence, it was concluded that the composite with DMAHDM content increased the antibacterial effect in a dose-dependent manner and provided sustained Ca and P ion release till 70 days.
