Abstract
A method for etching and treating a tooth surface prior to restoration, comprising a solution comprising of an —SO3 terminated compound resin, such as an —SO3H compound resin, and an aldehyde desensitizing compound. In practice, the composition is applied to the tooth surface and not subsequently washed prior to application of an adhesive or other restorative material.
Claims7
A method of etching and treating a tooth to increase adhesiveness, comprising:
- applying an etchant and treatment composition containing a compound comprising about 0.1 to about 50 weight percent of an olefinically unsaturated, —SO3 terminated monomer selected from the group consisting of AMPS, AMPS derivatives, SEM, SEM derivatives, SPM, SPM derivatives, or a mixture comprising at least one of the foregoing monomers;
- and further comprising about 0.1 to about 20% by weight, of a desensitizing aldehyde, such that when the composition is applied to the tooth surface, the adhesiveness of the tooth structure is increased;
- and applying an adhesive composition to the surface without applying a separate primer composition.
