| Abstract | PURPOSE: This paper aims to examine varied surface treatments combined with adhesive bonding to ascertain the highest bond strength of the composite resin repair. MATERIALS AND METHODS: A total of 100 specimens was made using an increment technique. The prepared specimens were aged for 20 days in 37 degrees +/- 20 degrees C water and then kept for 24 h at room temperature. The samples were separated into 5 groups of 20, and each group then received a different surface treatment (control group, phosphoric acid, diamond bur, air abrasion, silane primer combined with a diamond bur treatment). The effect of each surface treatment on the bond strength was determined by a shear bond test. RESULTS: Specimens that received surface treatment with a diamond bur exhibited higher shear bond strengths than any of the other repaired groups (p < 0.05). Those treated with air abrasion had the second highest shear bond strengths, but without a statistically significant difference when compared to the control group (p > 0.05). Specimens treated with phosphoric acid showed virtually no difference compared to the specimens of the control group (p > 0.05). CONCLUSION: Statistical analysis revealed that surface treatment with a diamond bur results in higher shear bond strength than other tested methods. |
