Results: Mean stain absorption was the highest with nanofilled composite resin (Filtek Z350 XT,3M ESPE) after exposure with light-curing intensity of 325–425 mW/cm 2 and least with microhybrid composite resin (Filtek Z100, 3M ESPE) after exposure with light-curing intensity of 750–850 mW/cm 2 and this difference found was highly significant statistically ( P < 0.001).
