عنوان انگلیسی Bond strength of composite resin to pulp capping biomaterials after application of three different bonding systems
چکیده انگلیسی مقاله Background and Aims: We aimed to assess the bond strength of composite resin to three pulp capping biomaterials; ProRoot mineral trioxide aggregate (PMTA), Root MTA (RMTA) and calcium enriched mixture (CEM), using three bonding systems [a total etch (Single Bond) and two self-etch systems (Protect bond and SE Bond)]. Materials and Methods: Ninety acrylic moulds containing a 6×2 mm hole were divided into 3 groups and were filled with PMTA, RMTA and CEM. The samples were then randomly divided into 3 subgroups; Single Bond, Protect Bond and SE Bond bonding systems were applied to the tested materials. Cylindrical forms of composite resin (Z100, 2×2 mm) were placed onto the samples and cured. Shear bond strength values were measured using a universal testing machine. Data were analyzed using Two-way ANOVA test. Results: The average shear bond strengths of Z100 composite resin after application of Single Bond, Protect Bond and SE Bond systems were as follows; PMTA: 5.1±2.42, 4.56±1.96, 4.52±1.7, RMTA: 4.71±1.77, 4.31±0.56, 4.79±1.88 and CEM: 4.75±1.1, 4.54±1.59, 4.64±1.78 megapascals respectively. The type of pulp capping material, bonding system and their interacting effects did not have a significant effect on the bond strengths of composite resin to pulp capping biomaterials. Conclusion: Within the limitations of this in vitro study, bond strength of composite resin to two types of MTA as well as CEM cement were similar following application of the total etch or self-etch bonding systems.
