Microleakage of a new cavity varnish with a high-copper spherical amalgam alloy.
In a study in vitro Copalite and Barrier cavity varnishes were applied to the walls of class 1 prepared cavities before placing Tytin, a high-copper amalgam. Tests with 45Ca and autoradiographs showed that at six months only Copalite was effective in preventing microleakage. At one year neither Barrier nor Copalite was preventing leakage.
