Clinical evaluation of compomer in primary teeth: 1-year results

The clinical performance of the compomer Dyract (L.D. Caulk, Dentsply) was evaluated and compared with that of the hybrid composite resin Prisma TPH (L.D. Caulk, Dentsply) in restorations of 60 bilateral matched pairs of primary teeth. After 1 year, the overall failure rate for both restorative materials was 1.7 percent. There were no statistically significant differences in recurrence of caries, color matching, marginal integrity or anatomic form. The only statistically significant differences were in marginal discoloration and wear, where the compomer was inferior to the hybrid composite resin. The authors conclude that compomer is a suitable alternative to amalgam for restoring primary teeth.
