PURPOSE To determine whether the use of microetching and bonding agents could improve the shear bond strength between aged and freshly added dental amalgam, simulating an amalgam repair.

Fresh amalgam was condensed through a split mold onto each prepared amalgam surface. Two control groups were included: a… CONTINUE READING
