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.
