Abstract
Objectives: This study evaluated the flexural strength and color stability of 3 bis-acryl resins (Luxatemp FluorescenceTM, Protemp 4TM and IntegrityTM) and a polymethyl methacrylate-based resin (Unifast TradTM) after different aging conditions.
Materials and Methods: Twenty bar-shaped specimens of each material were prepared for flexural strength test performed at 30 minutes after mixing, 24 hour and 7 day water storage with or without thermocycling. For color stability test, color parameters were measured on 20 disc-shaped specimens, 5 specimens for each material, at the same aging conditions.
Results: All bis-acryl resins showed low flexural strengths at 30 minutes after mixing but increased after 7 day water storage with or without thermocycling. Polymethyl methacrylate-based resin showed similar flexural strengths at all-time intervals. Color differences ( E) of all bis-acryl resins were less than that of polymethyl methacrylate-based resin. The greatest E was observed in a polymethyl methacrylate-based resin after 24 hour water storage. No significant differences of E among bis-acryl resins were detected in all conditions.
Conclusions: Bis-acryl resins showed higher flexural strengths and less E than polymethyl methacrylate-based resin. Thermocycling did not alter flexural strengths and color changes of these materials.
