Abstract
The present invention provides a dental hydraulic temporary sealing material composition on which a protection of tooth substance, such as tooth substance strengthening and control of secondary dental caries, can be expected by sustained-releasing various ions including a fluoride ion, while having a high initial setting ability. More specifically, the present invention provides a dental hydraulic temporary sealing material composition comprising 65.0% to 85.0% by mass of component (1): a hydraulic inorganic powder; 10.0% to 25.0% by mass of component (2): an organic solvent; 3.0% to 15.0% by mass of component (3): a resin; and 0.01% to 10.0% by mass of component (4): an ion sustained-release glass.

A dental hydraulic temporary sealing material composition consisting of:
- 65.0% to 85.0% by mass of component (1):
- a hydraulic inorganic powder;
- 10.0% to 25.0% by mass of component (2):
- an organic solvent;
- 3.0% to 15.0% by mass of component (3):
- a resin;
- 0.01% to 10.0% by mass of component (4):
- an ion sustained-release glass, and
- at least one additive selected from the group consisting of a pigment, a dye, a reaction adjustment agent, a filler, and an antibacterial agent,
- wherein the ion sustained-release glass is coated by a silane compound represented by formula (I):
- wherein Z is RO—, X is halogen, Y is —OH, R is an organic group having a carbon number of not more than 8, n, m, or L is an integer of 0 to 4, and n+m+L=4,
- wherein the addition amount of the silane compound ranges from 0.1 to 10 parts by mass in SiO2 conversion based on 100 parts by mass of the ion sustained-release glass,
- wherein the hydraulic inorganic powder is calcium sulfate, and
- wherein the resin is a vinyl chloride-vinyl acetate copolymer.
