Institut für Organische Chemie II, Universität zu Köln.

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.

D011791	Quartz	Quartz (SiO2). A glassy or crystalline form of silicon dioxide. Many colored varieties are semiprecious stones. (From Grant & Hackh's Chemical Dictionary, 5th ed)
D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.
