Class II Vitremer restoration of primary molars.

Several resin-modified, glass-ionomer cements have proved successful when used in Class III and Class V cavities in primary teeth. One of them, Vitremer, is proving to be very durable when used in Class I and Class II cavities in primary teeth. The material is handled as quickly and easily as silver amalgam. The components of the Vitremer Tri-Cure System are: Primer, Glass powder, Liquid, and Resin gloss. In addition to a light-curing mechanism, Vitremer hardens by the acid base, glass-ionomer reaction, and a chemical "dark cure", catalyzed by a reduction/oxidation reaction. Over 600 Class II Vitremer restorations have been placed and over 250 have been in the teeth long enough (12 to 18 months) to be observed regularly.
