Compomer that release fluoride could be used on proximal caries of child effectively. But oral cavity is always wet, so saliva inhibits bonding of tooth and compomer. When the saliva exist on bonding, it can be occured microleakages. The purpose of this study was to evaluate the influence of salivary contamination on compomer restoration and degree of microleakage according to restoration methods. Dyract AP^(¢ç) and prime and bond^(¢ç) NT was applied by the manufacture s instructions. Elipar Trilight was applied for light curing. Saliva pool was made for reconstruction of oral cavity. Two premolar was embedded in acrylic resin. After class II cavity preperation, Dyract AP^(¢ç) was restored under several condition, the specimen was thermocycled 500 times with 30 second dwell time. 0.5% methylene blue was used for microleakage test. Micoleakage was measured by the ratio of the infiltration length to occlusal and gingival side interface. Data were analyzed statistically using Kruskal Wallis Test, Mann-Whitney Test.

The Result were as follows;

1. In occlusal side, there were no statistical differences.

2. In gingival side, there were no statistical differences in Group III(ContactMatrix^(TM), Rubber dam, Oraseal^(¢ç), Group IV (No saliva contamination).

3. In gingival side, there were no statistical differences in Group I(ContactMatrix^(TM)), II(ContactMatrix^(TM), Rubber dam).

4. In gingival side, there were statistical differences in Group I(ContactMatrix^(TM)), II(ContactMatrix^(TM), Rubber dam).
