Resistance of cavity varnishes to solubility: a study in vit

Cavity varnishes are resinous materials used under permanent resotrations to protect dental tissues from marginal leakage and harmful components of the restorative material. These materials are soluble in the fluids of the oral cavity. The purpose of this study was to investigate, in vitro, the degree of solubility of these materials in different solvents over a period of time, to obtain an idea of their effectiveness.
