Abstract:
Abstract: Introduction: Solubility and sorption are material properties that can directly affect their stability, integrity, and durability at the site of application. Aim: The aim of this study was to examine the solubility and sorption of a newly synthesised nanomaterial based on calcium aluminate, calcium silicate, and MTA. Materials and methods: The study used a nanostructured calcium aluminate synthesised by the hydrothermal sol-gel method from individual components of calcium aluminate (CaO·Al2O3), calcite (CaCO3), and barium sulphate (BaSO4) as a radiopacifier, and a calcium silicate-based material. The mixed material was placed into plastic moulds 5 ± 0.1 mm in diameter and 2 ± 0.1 mm in height. After setting, the materials were kept in an incubator at 37°C for 24 h, after which they were removed from the moulds and liquid sorption of the materials was analysed. Eight specimens were prepared for each tested material (n = 8). MTA (Angelus, Londrina, Brazil) was used as the control material. Results: During 28 days of specimen storage in distilled and deionised water, liquid sorption for MTA was 12.71%, sorption for calcium silicate was 12.08%, while calcium aluminate showed a liquid sorption of 20.27%. Using Student's t-test, a difference was observed between calcium aluminate and MTA (t = -7.094; p = 0.000005) and between calcium aluminate and calcium silicate (t = -7.026; p = 0.000006), while the difference between calcium silicate and MTA was not statistically significant. Solubility for MTA was 8.53%, solubility for calcium silicate was 8.3%, while calcium aluminate showed a solubility of 23.68%. A significant difference was observed between calcium aluminate and MTA (t = 4.828; p = 0.001308) and between calcium aluminate and calcium silicate (t = 4.817; p = 0.000951), while the difference between calcium silicate and MTA was not statistically significant. Conclusion: The solubility and liquid absorption of the nanostructured calcium aluminate-based material were significantly higher compared with calcium silicate and MTA.
