Abstract: The present disclosure provides a root-canal sealer composition including cement and a hygroscopic liquid, in which the cement includes tricalcium silicate (3CaO·SiO2) in which an aluminum atom (Al) is solid-soluted (Al solid-soluted C3S), dicalcium silicate (2CaO·SiO2) in which an aluminum atom (Al) is solid-soluted (Al solid-soluted C2S), and tricalcium aluminate (3CaO·Al2O3) in which a silicon atom (Si) is solid-soluted (Si solid-soluted C3A), the tricalcium aluminate being disposed between at least one selected from the group consisting of the Al solid-soluted C3S and the Al solid-soluted C2S. When the cement including aluminum solid-soluted tricalcium silicate, aluminum solid-soluted dicalcium silicate, and silicon solid-soluted tricalcium aluminate is prepared and used for a root-canal sealer composition, a curing time is reduced and compressive strength is increased.
