Hydration behavior of an experimental tricalcium silicate/tetracalcium phosphate bio-cement in Streptococcus thermophiles bacterial solution in comparison with distilled water used as a root canal furcation perforation repair material

Abstract

The aim of this study is to evaluate an experimental tricalcium silicate phase (C3S) and tetracalcium phosphate (TTCP) material to be used as a root canal furcation perforation repair. C3S and TTCP phases were synthesized in nano-size particles by firing the required molar ratios of chemically pure reactants by solid-state reactions at elevated temperatures. The influence of Streptococcus thermophilus bacterial medium on the hydration reaction characteristics and morphology of 1:1 composite material of C3S and TTCP in comparison with distilled water was studied. Setting time, micro-hardness, pH of immersion solution, calcium ion concentration, phosphorous ion concentration, XRD, FTIR, scanning electron microscopy and cytotoxicity of the synthesized composite were investigated, and also, its sealing ability in bacterial media and in distilled water was evaluated.
