Abstract
A tooth-surface treatment agent for use with dental glass ionomer cement comprises (a) a polymer of an .alpha.-.beta. unsaturated carboxylic acid having a specific molecular weight, (b) a compound containing one or more of the elements selected from the group of aluminum, iron, tin, and calcium, and (c) water. This agent ensures the dissolution and removal of the smear layer, and improves and stabilizes the bonding strength of the glass ionomer cement to tooth structure. Also, the agent has a milder effect than the effects had by phosphoric acid, and has an action on reducing irritation to the dental pulp and is harmless thereto because it enables the smear plugs to remain in dentinal tubules.
Claims6
A tooth-surface treatment agent for use with dental glass ionomer cement, which comprises:
- (a) a polymer of an .alpha.,.beta.-unsaturated carboxylic acid having a weight-average molecular weight of 1,000 to 40,000,
- (b) at least one compound selected from the group consisting of aluminum oxalate, aluminum chloride, aluminum iodide, ferric chloride, iron citrate, iron oxalate, iron succinate, tin oxide, tin phosphate, calcium chloride, calcium acetate, calcium oxalate, and tetramethyl tin, and
- (c) water such that said treatment agent remains fluid and can be removed by rinsing with additional water prior to using said dental glass ionomer cement.
