Title: Adhesive bond strengths using self- and light-cured composites. Author: Walter R, Macedo GV, Oliveira GM, Swift EJ. Journal: J Contemp Dent Pract; 2009 Nov 01; 10(6):E025-32. PubMed ID: 20020078. Abstract: AIM: To evaluate the microtensile bond strength (microTBS) of four adhesive systems to dentin, using self- and light-cured resin composites. METHODS AND MATERIALS: Crowns of human molars were separated from the roots, and the occlusal surfaces were ground to obtain flat superficial dentin. Three etch-and-rinse adhesives--All-Bond 2, One-Step Plus, and OptiBond Solo Plus--and one self-etching primer system, Peak SE, were evaluated. Each adhesive group was divided into two subgroups according to the type of resin composite used. A self-cured (Bisfil 2B) or light-cured (Filtek Supreme Plus) resin composite build-up was incrementally inserted to the dentin after each adhesive system was applied. The bonded specimens were stored in water for 24 h and sectioned into beams. Microtensile testing was done, and the data were subjected to ANOVA and Fisher's PLSD test. RESULTS: The microTBS of All-Bond 2 and One-Step Plus was not affected by the type of resin composite used (p=0.3131 and p=0.1562, respectively). The microTBS of OptiBond Solo Plus was significantly reduced when used with self-cured resin composite (p<0.0001). Peak SE formed no bond of self-cured resin composite to dentin. CONCLUSION: Some adhesives do not effectively bond self-cured resin composite to dentin. CLINICAL SIGNIFICANCE: Incompatibility between adhesives with low pH and certain self-cured resin composites can cause clinical debonding of restorations.[Abstract] [Full Text] [Related] [New Search]
