Abstract

The purpose of this study was to investigate the interfacial bond strength of repaired composite resins, Lite-Fil P and Bis-Fil II, under different interfacial conditions. The matured composite resin specimen were prepared as Table I and divided into 9 groups. All specimens were stored in distilled water at $37^{\circ}C$ for 24 hours before testing. The results were as follows; 1. The bond strength of the groups that bonding agent was applicated was greater than that of the groups that bonding agent was not applicated. 2. The bond strength of the saliva contaminated groups was the lowest. 3. The bond strength of the group that chemical cured composite resin bonded to chemical cured composite resin was greater than that of the other groups. 4. The bond strength of the no-treated group was greater than that of saliva contaminated group, and lesser than that of the bonding agent applicated groups.
