Abstract
Introduction: Different surface preparation methods and types of bonding agents are key factors in improving bond strength. This study aimed to evaluate the effect of air abrasion and silane on the shear bond strength of repaired posterior composite restorations using universal and fifth-generation adhesives.
Materials and Methods: In this in vitro study conducted in 2024 at Islamic Azad University, Isfahan, 128 resin composite disc samples were fabricated. The prepared posterior composite samples underwent repair procedures using various surface preparation techniques. Half of the samples were divided into four groups for sandblasting, while the other half were divided into four groups that did not undergo sandblasting. Some samples were treated with silane, and two types of adhesives (universal and fifth-generation) were used to assess bonding performance. Shear bond strength was then measured. Data were analyzed using ANOVA and Sidak post hoc tests (α = 0.05).
Results: The use of air abrasion and silane significantly increased bond strength (P < 0.001). The highest mean shear bond strength was observed in Group 2 (“sandblasted – universal adhesive – with silane”), while the lowest mean shear bond strength was seen in Group 7 (“non-sandblasted – fifth-generation adhesive – without silane”). Sandblasted groups, regardless of adhesive type or silane application, exhibited significantly higher shear bond strength than non-sandblasted groups (P < 0.001).
Conclusion: Mechanical surface preparation by air abrasion and the application of silane are recommended as effective methods for enhancing bond strength.
