Micro-shear Bond Strength of Aged Resin Composite Repaired with Different Universal Adhesives
Journal Title: Meandros Medical and Dental Journal - Year 2019, Vol 20, Issue 1
Abstract
Objective: This study evaluated the effect of two different universal adhesives on the repair bond strength of aged resin composite. Materials and Methods: Forty-four composite resin disks were prepared (5 mm x 3 mm). The composite disks randomly assigned into four groups after aging. Specimens were repaired with resin composite using four different repair procedure; Porcelain primer + Clearfil S3 Bond Plus, Single Bond Universal, Clearfil Universal Bond, Clearfil S3 Bond Plus, then they were subjected to micro-shear bond strength testing. Data were analyzed using ANOVA and Tukey’s HSD (p<0.05). Results: Additional silane treatment significantly affected the repair bond strengths (p<0.05). No statistical difference was found in repaired groups with universal adhesives. One-step self-etch adhesive showed lower bond repair strength values in aged composite repair (p<0.05). Conclusion: Repair of composite restorations with universal adhesives cannot suggest without additional silane application.
