The purpose of this study was to compare the amount of fluoride release and remineralizing effect of compomer with those of glass ionomer cement and composite resin.
Composite resin(Z-100¢¥)was used for negative control group (Group I), glass ionomer(Fuji II LC) for positive control group(Group IV), compomer(Dyract AF¢¥ and F-2000¢¥) for experimental group(Group II and Group III).

The results obtained can be summarized as follows
1. ,Glass ionomer showed the higher amount of fluoride release than compomer groups. Composite resin showed no fluoride release during test period.
2. Significant evidence of remineralization could be noticed in samples of all groups. The highest degree of remineralization was observed in glass ionomer group followed by compomer group. The least evidence of remineralization was observed in composite resin group.
3. Microhardness values of carious site was lower than control site, but Microhardness values of caries site at 20wn away from filling materials in group II, III, IV was significantly higher than the other area.
Based on the above results, compomer could be considered as one of the very attractive restorative materials in the field of pediatric dentistry.
