Abstract
Core buildup materials are essential to improve the longevity of tooth restorations. However, there is increasing concern as to whether moisture affects the properties of core buildup materials. In this work, the creep behavior of core buildup materials in artificial saliva was evaluated for up to 150 d. Five commercial materials were investigated: LuxaCore Z-Dual (LC), Nanofil DC Core composite (NF), EmbraceCore Resin Cement (EC), ParaCore (PC), and Smart Dentin Replacement (SDR). Specimens were made within stainless steel split molds. Creep strain was measured using a mechanical testing machine at four different time intervals. Each specimen was consistently loaded for 2 h at 36 MPa. The highest creep strain was found at 1 d for all materials. No statistically significant differences were found in the maximum creep strains for LC at 1, 30 and 150 d. The materials NF and EC showed the lowest creep strain at 90 d, while PC and SDR showed the lowest creep strain at 150 d. All test materials exhibited classic creep behavior, but the creep strain values varied due to the different matrices, fillers, and immersion periods.
