First Claim
Patent Images
1. A method for sanitizing dental equipment containing microbes, said method comprising the steps of:
- (a) contacting said dental equipment with an effective amount of a treating composition containing a surfactant and a solvent which generates heat under microwave radiation and a bleaching agent; and
(b) subjecting said dental equipment and said treating composition to microwaves for an effective amount of time such that a sanitizing amount of said microbes are removed from said dental equipment, wherein the combination of the amount of the treating composition and the time of microwaving sterilizes said dental equipment.

Abstract
A method by which dental equipment, such as dental scalers, can be sanitized using a detergent or treating composition containing a surfactant and a solvent such as water is disclosed. The method involves taking the used dental equipment and contacting it with the treating composition, and subjecting both the equipment and composition to microwaves. The composition foams during microwaving and/or immerses the equipment such that microwave arcing is avoided, and such that the dental equipment is sanitized.
