<p>A dentinal tubule sealant comprises poorly-soluble calcium phosphate particles (A), a phosphorus-free calcium compound (B), and water (C), wherein the particles (A) are at least one member selected from the group consisting of dicalcium phosphate anhydrous [CaHPO 4 ] particles, ±-tricalcium phosphate [±-Ca 3 (PO 4 ) 2 ] particles, ²-tricalcium phosphate [²-Ca 3 (PO 4 ) 2 ] particles, amorphous calcium phosphate [Ca 3 (PO 4 ) 2 €¢nH 2 O] particles, calcium pyrophosphate [Ca 2 P 2 O 7 ] particles, calcium pyrophosphate dihydrate [Ca 2 P 2 O 7 €¢2H 2 O] particles, octacalcium phosphate pentahydrate [Ca 8 H 2 (PO 4 ) 6 €¢5H 2 O] particles, and dicalcium phosphate dihydrate [CaHPO 4 €¢2H 2 O] particles, and the dentinal tubule sealant contains 30 to 76% by weight of the particles (A), 0.001 to 4% by weight of the compound (B), and 23 to 69% by weight of the water (C). Thus, there is provided a dentinal tubule sealant capable of sealing dentinal tubules of an exposed dentin and also remineralizing the surrounding dentin after the sealing.</p> |
