Pre-mixed strontium silicate-based biological hydraulic cementing paste composition, preparation method therefor, and application thereof

Abstract

A pre-mixed strontium silicate-based biological hydraulic cement paste composition and preparation method and use thereof are disclosed. The pre-mixed strontium silicate-based biological hydraulic cement paste of the disclosure uses strontium silicate as the main phase and at least one non-aqueous solvent that is miscible with water, and preferably, it may further include at least one calcium phosphate compound and at least one radiopaque material, to prepare a biological hydraulic cement paste with excellent injectability. The material remains as a fluid under a sealed condition, and hydrates, solidifies and hardens when it is placed in a physiological environment and contacts with a physiological body fluid. The strontium silicate-based material having excellent biocompatibility and biological activity is used to prepare a pre-mixed strontium silicate-based cement paste, which can be used for medical and dental applications including fields of pulp capping, root canal therapy, dental restorations and the like.
