Title:
DENTAL APPARATUS WITH OZONE IRRIGATION SYSTEM
Document Type and Number:
WIPO Patent Application WO2005032393
Kind Code:
A3
Abstract:
A dental apparatus is provided with an ozone irrigation system. Ozonated water is produced in the irrigation system and supplied to the dental apparatus. The dental apparatus can have a handpiece that drives a cannulated instrument, such as a cannulated file. The ozonated water can be supplied to an axial passage formed in the instrument. Radial ports are provided through the instrument such that the ozonated water can spray radially outward into a treatment zone during movement of the instrument. The ozonated water thereby can lubricate and cool the treatment zone while also providing advantageous cleaning of the zone.
