Abstract
A dental mirror includes a handle with an enclosure head on the end. The enclosure has a cover which is partially mirrored and partially transparent, a light source within it, and a concave reflector around the light source to reflect light through the transparent portion of the cover, the reflected light converging in front of the mirror. Heat from the light source keeps the mirror free of fogging.
