| dc.description.abstract | Background: With the development of bulk-fill flowable composites, dentists are increasingly opting to dispense of the time-consuming layering required of conventional universal composites. It has been suggested that a reduction in cuspal deflection can be expected when modifications to the interfacial stress concentrations in large composite restorations are introduced. It has further been demonstrated that fiber-reinforced composite restorations reduce stress accumulation on the remaining hard tissue. Aim: To determine the cuspal deflection of teeth restored with bulk fill flowable composite resins, with and without fiber-reinforcement and evaluated by micro-computed tomography. Methods and Materials: A comparative in vitro study was designed utilizing micro-CT scanning. Standardized mesio-occlusal-distal (MOD) preparations restored with three different bulk fill flowable composite resin systems, with and without Ribbond fiberreinforcement, were assessed and compared. The flowable bulk fill composites tested in this study were Filtek Bulk Fill (3M), Palfique Bulk Flow (Tokuyama) and Tetric N-Flow (Ivoclar Vivadent). Scans were after fiber placement (uncured), the tooth after curing of the fiber, the tooth after placement of the composite (uncured) and lastly, the tooth after curing of the composite. Scanned data were analyzed using Volume Graphics VG Studio Max 3.2.5 (Nagoya, Japan). The mechanical properties of these materials and the influence of Ribbond fibers on compressive strength was evaluated by means of catastrophic compressive strength testing. | |
