ABSTRACT:
A method of preparing an impression of dentition in the oral cavity is provided that overcomes a problem of transfer of inhibitors left by latex gloves that interfere with platinum catalyzed hydrosilation reactions. The method involves applying a surfactant, preferably with peroxide, to the area that is to have its impression taken substantially immediately before applying the impression taking material, rinsing the composition from the area and proceeding with the taking of the dental impression. Preferably the decontaminating composition consists essentially of surfactant, especially polyoxyethylene surfactants, hydrogen peroxide and water.
