ABSTRACT
The purpose of this study was to evaluate the fluoride release and anticariogenic effect of two compomers which is known to have been developed to improve the weak properties of glass ionomer cement and composite resin. Z-100 as composite resin(Group I), Dyract AP(Group II) and F-2000(Group III) as compomer, and Fuji II LC as glass ionomer cement(Group IV) were used as test materials and evaluations were peformed by pH/ISE meter far analyses of fluoride and polarizing microscope for analyses of anticariogenicity. The results can be summarized as follows: 1. The amount of fluoride release in compoite resin and compomer groups showed general pattern of decline during test period. Z-100 showed no fluoride release during test period. Fuji II LC showed the highest fluoride release among test groups and then F-2000 were followed. 2. The least resistance to dimineralization was observed microscopically in Z-100 group which has no fluoride in it. The best resistance to dimineralization was observed microscopically in Fuji II LC group and then compomer groups were followed. 3. Significant difference in lesion area was found between Fuji II LC group and another groups. Significant difference in lesion area was found between compomer groups and Z-100 group. No significant difference in lesion area was found between Dyract AP group and F-2000 cup. 4. Two compomers showed continual fluoride release and anticariogenic effect around filling materials. therefore, compomer was evaluated very attractive restorative material in pediatric dentistry.
