Compomers as Class II restorations in primary molars

A variety of alternatives to amalgam are now available for use in class II restorations in primary teeth, including glass ionomer, composites, and intermediate materials such as compomer and resin modified glass ionomers (RMGI). The purpose of the present study was to evaluate the clinical performance of two compomers, Hytac and Dyract, and to compare these results to those reported for other intracoronal restorative materials. Evaluation after 24 months shows Hytac and Dyract to have performed well and comparably as class II restorations in primary teeth. The low failure rate, even in a population with a high caries increment, suggests that compomers are a suitable alternative to amalgam or other, tooth-colored materials when used as class II restorations in primary teeth.
