![]() ![]() TCS 50 is a promising cement formulation to serve as a biocompatible hydraulic calcium silicate cement.Ĭa release Component distribution Cytotoxicity Mini-fracture toughness Tricalcium silicate Zirconium oxide. Chemical composition Portland cement is made up of four main compounds: tricalcium silicate (3CaO SiO 2 ), dicalcium silicate (2CaO SiO 2 ), tricalcium aluminate (3CaO Al 2 O 3 ), and a tetra-calcium aluminoferrite (4CaO Al 2 O 3 Fe 2 O 3 ). ZrO 2 can be added to TCS without affecting the mini-FT Ca release was reduced initially, to reach a prolonged release thereafter adding ZrO 2 made TCS cements more biocompatible. The 24-, 48-, and 72-h extracts of TCS 50 were the least cytotoxic. ![]() Particles with an un-reacted core were surrounded by a hydration zone. EPMA revealed a more even distribution of ZrO 2 within the TCS cements. After 1 week, Ca release from TCS 30 and TCS 50 increased to a level that was significantly higher than that from Biodentine (p 0.05). Ca release from TSC cements was slightly lower than that from Biodentine at 1 day (p > 0.05). Cements used in wells are subjected to conditions not encountered in construction, such as wide. These cements are designed to meet the varying needs of the construction industry. Cytotoxicity was assessed using an XTT assay.Īdding ZrO 2 to TCS did not alter the mini-FT (p = 0.52), which remained in range of that of Biodentine (p = 0.31). C150 1 provides for eight types of Portland cement: Types I, IA, II, IIA, III, IIIA, IV, and V, where the A denotes an air-entraining cement. The component distribution within the cement matrix was evaluated by Feg-SEM/EPMA. ![]() Regarding bioactivity, Ca release was assessed using ICP-AES. To evaluate the potential effect on mechanical properties, the mini-fracture toughness (mini-FT) was measured. Biodentine (contains 5 wt.% ZrO 2) served as control. The powders were mixed with 1 M CaCl 2 solution at a 3:1 weight ratio. TCS powders were prepared by adding ZrO 2 at six different concentrations. This study aims to investigate the effect of modifying tricalcium silicate (TCS) cements on three key properties by adding ZrO 2.
