Effect of storage media on the fluoride release and surface microhardness of four polyacid-modified composite resins (“compomers”)

Objectives. The aims of this investigation were to measure the surface microhardness (Vickers) as well as the release of fluoride from four polyacid-modified composite resins (PMC) (“compomers”) (Compoglass F, F 2000, Dyract AP, experimental compomer) after storage in various artificial saliva (buff...
