Abstract
A dental working element guard may include grip enhancements such as finger plates or cups. Embodiments can accommodate contra-angles. Guards made of transparent plastic improve work area visibility for a dentist or user. Some embodiments are made of plastic and are disposable. Embodiments may include a lubrication port for introducing a lubricant. The port may include an orifice in a wall of the guard. The port may also include a tube, for guiding the placement of a lubricating hypodermic needle and/or a hose barb for communication with a lubrication source via tubing. The guard may be used in conjunction with known working elements such as grinding disks or in conjunction with an improved grinding disk having a pilot region or ring that does not include abrasive material and aids in positioning the disk between teeth. A disk stop can position a disk for receiving lubricant.
