What is Effect of Sandblasting on the Bond Strength of the Bondable Molar Tube Bracket about?

This study examined the effect of surface treatment with sandblasting on bracket bonding strength. Extracted human tooth, base metal alloy and porcelain surfaces were treated with sandblasting. The bracket bonding strengths of sandblasted surfaces were evaluated and compared with the controls and etched enamel surfaces. Morphological observation of the treatment surfaces and the failure sites was conducted. Statistical analysis included one-way analysis of variance (ANOVA) and a Scheffe's F-test at the 95% confidence level was performed. The results indicated that mean bond strength values ranged from 3.6 MPa (the untreated control) to 20.4 MPa for the etched enamel surface. No statistically significant differences were determined among the etched enamel, sandblasted metal and sandblasted porcelain surfaces (P > 0.05). Most debonding specimens failed at either the resin-tooth interface or within the adhesive. In conclusion, sandblasting the metal and porcelain surfaces obtained a bracket bond strength comparable with that with the etched enamel surface.
