DENTAL MIRROR
NO-BLUR™

The present invention overcomes the aforementioned disadvantages by providing a new and improved approach to the problem of condensation on the face of a dental mirror. A dental mirror, of course, typically includes an elongated handle or shaft having an oval or circular mirror secured to the handled. The mirror may be set at an obtuse angle to the shaft.

The present invention contemplates a protective covering over the mirror surface with the protective covering which may be in air tight contact with, or hermitically sealed to, the mirror such that air is precluded from entering any space between the mirror and the protective coating. The preferred protective covering or coating is made of a clear plastic and is preferably domed or convex. The preferred protective coating may be sealed to the mirror by a snap fit or by a molding process, or threaded onto the mirror frame. A gas, liquid (such as mineral oil), semi-solid or solid plastic may be interposed between the coating and the mirror to enhance the optical quality of the mirror system.
