| 摘要 |
The present invention provides a dentinal tubule sealing material having superior durability (acid resistance) of the dentinal tubule sealing properties and also superior storage stability. The dentinal tubule sealing material contains tetracalcium phosphate particles (A), calcium hydrogenphosphate particles (B), calcium carbonate particles (C), and a non-aqueous dispersing agent (D), wherein for every total of 100 parts by weight of the tetracalcium phosphate particles (A), calcium hydrogenphosphate particles (B), calcium carbonate particles (C), there are 5-75 parts by weight of the tetracalcium phosphate particles (A), 10-70 parts by weight of the calcium hydrogenphosphate particles (B), and 2-50 parts by weight of the calcium carbonate particles (C). |
