The purpose of this study was to examine and evaluate a possible influence of individual processes in the bonding systems on the adhesive durability of resin composite to enamel. The experiments were performed by 5 dentists. Bovine enamel was used as an adhered, while 6 kinds of bonding systems were used in the experiment. Adhesive specimens were prepared at 23±2℃ room temperature and 50±5% relative humidity. The adhered area was standardized to be 6mm in diameter by means of masking tape. The adhesive specimens were subjected to durability test by immersing in distilled water at 37℃ for 24 hours (CO) and 30000 cycles of thermal stress at 4-60℃ (TH). After completion of the durability test, shear bond strength test was performed by using an universal testing machine to determine the adhesive strength. The significant difference was then assessed by One way ANOVA and Tukey's HSD test. The results obtained were as follows: 1. No significant difference was observed in bond strength in the bonding system which adopted acid processing of phosphoric acid among 5 dentists. 2. Significant difference was observed in bond strength in the bonding system which adopted acid processing of 10% citric acid-3% ferrous chloride between 5 dentists. 3. Significant difference was observed in bond strength in the bonding system which adopted selfetching primer among 5 dentists.
