Effect of Different Surface Treatments on Repair Bond Strength of Aged Tooth Colored Materials
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 3
Abstract
Objectives: The aim of this investigation was to assess the influence of different surface treatments and repair material on the repair shear bond strength (SBS) of GC Fuji IX GP Packable Posterior Restorative, Filtek Bulk Fill, and Filtek Supreme Ultra Flowable. Methods: Thirty cylindrical specimens were prepared from each material and randomly allocated into 3 groups/10 each. Group 1: no surface treatment (control), group 2 (treatment 1) where a GC G-Bond was applied while group 3 (treatment 2) the G-Bond was applied after roughening the surface with a finishing diamond bur. All specimens were bonded to Heliomolar Flow. The SBS was measured using a universal testing machine. Results: There were significant effects of surface treatments, materials, and interaction (p<0.01). For GC Fuji IX GP and Filtek Bulk Fill; treatment 2 exhibited significantly higher SBS than either no surface treatment or treatment 1 which were not statistically significantly different from each other. For Filtek Supreme Ultra Flowable; there was a statistically significant difference in SBS between all treatments. Conclusion: Application of self-etching adhesive after roughening the surface with a finishing diamond bur produces the highest repair SBS for GC Fuji IX GP, Filtek Bulk Fill, and Filtek Supreme Ultra Flowable.
