Aim: The aim of this in vitro study was to evaluate the thermal aging effect on microhardness and surface roughness of fluoridecontaining restorative materials.Material and Methods: In this study, a bioactive material (Activa Bioactive Restorative, Pulpdent, Watertown, MA, USA), a giomer(Beautifil II, Shofu, Kyoto, Japan), a nanohybrid composite (Charisma Smart, Heraeus Kulzer, Germany), a resin-modified glassionomer (Ionoseal, VOCO, Germany), and a bulk-fill glass-hybrid material (Equia Forte, GC, Tokyo, Japan) were used. 10×2 mm discswere prepared (n=10) and then polymerized. Only for bulk-fill glass-hybrid specimens, one layer of coat was applied on top surfacesand light cured. Before and after thermal aging procedures, initial and final surface roughness and microhardness values wereevaluated. One-Way ANOVA test was used for the statistical analysis (p<0.05).Results: Thermal aging did not affect the surface roughness of restorative materials statistically (p>0.05). After thermal aging whenthe bottom surface of Equia Forte compared to Activa Bioactive and Beautifil II in terms of microhardness values, a staticticalsignificant difference was observed (p<0.05).Conclusion: Even before and after thermal aging procedures, successful results can be achieved with bulk-fill glass-hybrid material.
