title: [Study on the residual monomer contents of different light curing hybrid composite resins].
abstract: In this study the methanol and aqueous extracts of four modern light-curing hybrid composite resins (unpolymerized and polymerized) were examined for eluable organic components by means of gas chromatography/mass spectroscopy. All substances found in the methanol extracts of the unpolymerized specimens were identified in the elutions of the cured materials too. Furthermore, all cured specimens contained at least one additional eluable component created during polymerization. In each composite resin there was at least one extractable substance which is classified as toxic.
