A comparison of amalgam microleakage with a 4-META liner and copal varnish.

Abstract

This in vitro study compared the microleakage of Class 5 amalgam restorations placed in extracted human teeth lined with a 4-META liner (Amalgambond), with similar restorations lined with copal varnish (Copalite). The restored teeth were stored in saline for 1 week, 6 months, and 1 year, then thermocycled, stained with 5% methylene blue, sectioned, and… (More)
