The effect of Antibacterial Nanoparticles, Incorporated in cement, on S.mutans in the margins of provisional restorations is going to be examined clinically by using two kinds of provisional cement 1. cement with out antibacterial nanoparticles.

2.cement with small addition of IABN. after one week in the mouth the crowns are to be removed and examined for the presence and quantity of s. mutans. in vitro tests of the same has shown significant reduction in bacterial population around the provisional cement as compared to the regular cement.
