Abstract
A tooth treated with a bonding composition with high initial bonding strength and good bonding durability comprising a mixture of polymerizable compound having an acid group, a water-soluble film-forming agent, water, and a curing agent, in which the calcium salt of the acid is insoluble in water, and the film-forming agent is a polymerizable compound miscible with a physiological saline solution, does not require any pre-treatment such as acid-etching or priming treatment.
Claims23
A bonding composition for tooth tissue, comprising:
- a mixture of a polymerizable vinyl compound having acid group, a water-soluble film-forming agent, water, and a curing agent;
- wherein a calcium salt formed from said polymerizable vinyl compound having an acid group is insoluble in water;
- wherein said polymerizable vinyl compound having an acid group is selected from the group consisting of a di(meth)acryloyloxyalkyl phosphate, a (meth)acryloyloxyalkylaryl phosphate, a (meth)acryloyloxyalkylaryl phosphonate, a (meth)acryloyloxyalkyl thiophosphate, a di(meth)acryloyloxyalkyl thiophosphate, a (meth)acryloyloxyalkylaryl thiophosphate, a (meth)acryloyloxyalkylaryl thiophosphonate, a (meth)acryloyloxyalkoxycarbonylphthalic acid, a (meth)acryloyloxyalkoxyalkoxycarbonylphthalic acid, an anhydride of (meth)acryloyloxyalkoxycarbonylphthalic acid, an anhydride of (meth)acryloyloxyalkoxyalkoxycarbonylphthalic acid, an anhydride of dicarboxylic acid, and a mixture thereof;
- wherein said film-forming agent is a polymerizable compound;
- and
- wherein said film-forming agent is miscible with a physiological saline solution.
