Abstract: An air emitting light and shielding apparatus for dental treatment comprised of a pressurized air source connected to an adjustably positionable air emitting light formed so as to develop an air envelope substantially surrounding the face and oral cavity or other body parts of a patient residing in a selected position in the dental chair or other operating table including positions in which the patient may be tilted such that vapors, blood, saliva splash, dental particles, or other foreign matter propelled from the patient's oral cavity during drilling, air-water syringing, or the like, are deflected by the inner boundary of the air envelope and are transported downstream of the patient's oral cavity for collection on a disposable patient drape thereby preventing the same from reaching the face and respiratory tract of a dental team member operating on the patient.

Abstract: A cleaning apparatus for small, ferrometallic, precision items, e.g., dental burs, includes a cabinet unit housing a plurality of magnets mounted on a motor driven, rotatable disc with the magnets being arranged and designed to provide a rotating, unipolar, non-uniform, magnetic field coacting with the items in which individual fields are induced and which provide for rotation separation and oscillation of the dental burs being cleaned in a solution within an appropriate container; a second group of magnets also mounted on a rotatable disc for rinsing of the cleaned dental burs; and a degaussing unit for demagnetizing the dental burs once cleaned and rinsed. A magnetic bur pick-up device allows for moving the dental burs from one area to the next without physical contact of the already cleaned burs.
