  • Method for adhering to tooth structure
    Patent number: 5645429
    Abstract: A method is provided for clinical retention of restorative material by a natural tooth. A first portion of photopolymerizable liquid primer/adhesive dental composition is applied to a tooth surface. After leaving the first portion of the liquid composition on the tooth surface undisturbed for at least 15 seconds on the tooth surface air is conveyed against the first portion of the liquid. The light is impinged on the first portion of the liquid composition whereby at least a portion of the first portion of the liquid composition polymerizes to form a first coating on the tooth. A second portion of the liquid composition is applied to the first coating, and air is substantially immediately conveyed to the second portion of the liquid composition.
