抄録
The purpose of this study was to evaluate the effect of flowable composite on the marginal sealing and cavity wall adaptation of composite restorations, and on the hardness, elastic modulus and flexural strength of resin composite. Cylindrical cavities, 1 mm deep and 3 mm in diameter (C-factor= 2.3) were prepared on flat bovine dentin surfaces. The teeth were restored with Clearfil SE Bond adhesive system followed by Photo Clearfil Bright or Filtek Flow composites. The resins were cured with 600 mW/cm2 40 s using experimental light curing unit. After thermocycling, dye penetration tests were carried out. Composite specimens of 2 mm thickness were polymerized in Teflon molds with 600 mW/cm2 40 s using experimental light curing unit. KHN and elastic modulus measurementswere taken at the top and bottom surfaces of each specimen using Knoop Hardness tester and Nano-indentation tester respectively. Composite specimens of 2×2×8 mm were polymerized in Teflon molds, flexural strength were measured using three point bending test. The flowable composite significantly improved adaptation of resin composite to the cavity wall, and flexural strength, bottom surface microhardness and elastic modulus. However, cured resin composite showed significantly lower microhardness compared with the conventional composite.
