Enhancing the Physical Properties of Calcium Silicate Cement Modified with Elastin-like Polypeptides and Bioactive Glass
Conventional calcium silicate cement (CSC) formulations often exhibit insufficient mechanical strength and low initial stability. This study aimed to develop an organic–inorganic hybrid biomaterial by incorporating an elastin-like polypeptide (ELP) (V125E8) and bioactive glass (BG) (63S) into CSC to...

| Summary: | Conventional calcium silicate cement (CSC) formulations often exhibit insufficient mechanical strength and low initial stability. This study aimed to develop an organic–inorganic hybrid biomaterial by incorporating an elastin-like polypeptide (ELP) (V125E8) and bioactive glass (BG) (63S) into CSC to improve its mechanical properties and wash-out resistance during the initial setting. Experimental groups included ProRoot MTA (Dentsply Sirona, USA) as a control (0BG), inorganic hybrids containing BG (2% or 5%; 2BG, 5BG), and organic–inorganic hybrids combining BG (2% or 5%; 2BG-L, 5BG-L) with a 10 wt% ELP solution. The compressive strength, microhardness, and wash-out resistance of the specimens were evaluated. The organic–inorganic hybrid groups (2BG-L and 5BG-L) exhibited significantly higher compressive strength and microhardness than the control (0BG) and inorganic-only groups (2BG and 5BG). Additionally, the incorporation of ELP markedly improved wash-out resistance, minimizing material disintegration during the initial setting in aqueous environments.
