Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a silicone-based curable composition with hydrophilic properties, hard to cause separation of additives etc., in preserving for long time, and excellent in storage stability. SOLUTION: The silicone-based curable composition for dental use comprises a branched polyglycerol-modified silicone, bonded to a silicon atom thereof via a linking group, at least one branched polyglycerol chain, specifically, a preferable addition reaction type silicone curable composition comprising (A) an organopolysiloxane having at least two organic groups in the molecule with unsaturated bonding on a terminal, (B) an organohydrogenpolysiloxane having at least three SiH groups in the molecule, (C) an organohydrogenpolysiloxane having two SiH groups in the molecule, (D) a catalyst substance for hydrosilylating reaction, (E) a filler and (F) branched polyglycerol-modified silicone.
