ABSTRACT:
A dental cement system containing a photocurable ionomer, reactive powder and water undergoes both a conventional setting reaction and a photocuring reaction.
The cement system can provide a long working time and can be cured on demand by exposure to an appropriate source of radiant energy. The surface of the cement cured in this manner is then hard enough to allow subsequent clinical procedures to be performed, while the ongoing chemical-cure "setting" reaction hardens the remainder of the cement.
