The influence of different radiopacifying agents on hermetical sealing ability of calcium silicate and calcium aluminate dental cements
Abstract
<jats:p>This study presents technological process for obtaining strontium enrichedcalcium silicate based dental ceramics and testing their microstructural andchemical properties. In brief, the influence of different radiopacifiers onmicrostructural properties of calcium-silicate (CaSi) and calcium-aluminate(CaAl) dental ceramics was evaluated. For synthesis of CaSi-based ceramics,calcium chloride pentahydrate (CaCl2?5H2O) and silica sol obtained byhydrothermal treatment were used. CaSi+barium-sulphate (BaSO4),CaSi+bismuth-oxide (Bi2O3), CaAl+zirconium-dioxide (ZrO2),CaAl+strontium-carbonate (SrCO3), CaAl+strontium-fluoride (SrF2),pure CaSi,pure CaAland mineral trioxide aggregate (MTA) (control material) were used.The wettability, surface free energy (SFE), microporosity, nano-porosity andmicro-gap size between the material and tooth root canal were evaluated.There was no difference in total SFE among tested cements (p<0.05), whileCaSi+BaSO4, CaAl+SrCO3 and CaAl+SrF2 experienced superior wetting than othercements (p<0.05). The highest microporosity was observed in CaAl, whilstadding radiopacifiers into it decrease cements microporosity (p<0.05). Thelowest nanoporosity was found for CaAl+ZrO2. The gap size was notstatistically different among tested ceramics (p>0.05). Altogether,strontium containing radiopacyfiers result in improved microstructuralcharacteristics of dental ceramics.</jats:p>
