Abstract

Background. Restorative filling materials used in dentistry are required to have long-term durability in the oral cavity. One of the most important physical properties of restorative filling material is surface hardness. Wear of composite resins is associated with a lower surface hardness. Purpose. The aim of this in vitro study was to evaluate the influence of different immersed times on surface hardness of nano composite stored in saliva pH 5,5. Method. A total of 28 specimens were fabricated for each of nanofill composite 3M ESPE FiltekTM Z350 according to the manufacturer’s instructions. The 28 specimens were randomly selected and stored in artificial saliva for 10, 20, 30 days. After 10, 20, and 30 days conditioning period, surface hardness testing was carried out with a Micro Vickers Hardness Tester. Results. The influence of the materials tested was statistically significant. After 30 days storage in artificial saliva, the VHN value of nanofill composite lower than storage in artificial saliva for 10 days. Conclusion. The surface hardness of composite resin materials are strongly influenced by different immersed times in artificial saliva pH 5,5.
