One embodiment of the present invention provides a light device. The light device may include a mirror and comprises a handle having a longitudinal axis, a mirror attached to the handle and arranged at an angle from the longitudinal axis, a light source inside the handle, and a light waveguide adjacent to the light source. The waveguide comprises an internal reflector, and the reflector reflects substantially all of the light from the light waveguide. In one embodiment, an annular air flow substantially aligned with a longitudinal axis of the mirror cools the apparatus, including the light source. One embodiment of the light mirror keeps the reflective surface of the mirror free of debris, water, restorative materials, tooth structure, and aluminum oxide powder. Thus, the operator may continue to work without the constant cleaning of the mirror surface associated with conventional mirrors. Cleaning the mirror during a procedure can be time-consuming and counter-productive. Moreover, one embodiment of the light mirror is more ergonomic and reduces eye strain, enabling more accurate and precise results in far less time than possible with conventional light mirrors.
