In another aspect, a method for directing streams of light, fluid, air, or suction toward a target during a dental procedure, comprising the steps of attaching a manifold having output orifices for light, fluids, air, or suction to a body of the tool; connecting the orifices to sources of light, fluid, air, or suction; and controlling a substance emitted from the orifices to be directed toward the target.

The present invention is directed to an anti-fogging / anti-splash composition that can be used for anti-fog / anti-splash applications. When applied to the surface of a transparent or reflective substrate, the composition dries relatively clear and comprises a solution of a non-toxic, fast drying solvent or alcohol and a surface active agent containing sodium lauryl ether sulfate, and either a block ethylene oxide / polyethylene oxide copolymer, an ethoxylated amine, an ethoxylated acetylenic alcohol, sodium sulfosuccinate, ethoxylated sorbitan ester, random EO / PO polymers on butyl alcohol, or mixtures thereof. When applied to the surface of a substrate, the present invention provides a coating of high transparency which cures rapidly, is sufficiently surface active to be an anti-fog agent when "dry", will persist when "wet" under water spray conditions (such as on a dental mirror) for a period substantial enough to be practicable, and will provide anti-splash benefits throughout the use cycle.

The invention relates to mirrors for use in confined spaces which are subject to being covered by fluids and debris, principally dental mirrors, for use by dentists and similar medical professionals. The mirror assembly includes a head portion and a handle portion. The head portion includes a housing with a rotor assembly and a rotor drive means. In accordance with the invention, a secondary member has a reflective surface. The mirror assembly includes attachment means for removably attaching the secondary member with respect to the rotor assembly so that the reflective surface can be replaced when degraded. In use, the rotor drive means spins the rotor assembly and with it the secondary member to remove fluids and debris that may fall on the reflective surface so that vision when using the reflective surface is not impaired by such fluids or debris. Advantageously the attachment means include magnetic components although mechanical attachment means may also be used. In a preferred embodiment, the handle portion includes a light source which may be moved between first and second positions for lighting the work zone of the mirror selectively as desired.

A self cleaning dental mirror having air orifices and water orifices integrated into the handle to clean the reflective surface.
