ABSTRACT:
A light shield for a dental composite curing gun which can be easily snapped on and off of a probe of the gun is provided. The shield includes a tinted, transparent main body which absorbs certain components of light reflected from a tooth surface being restored, thereby enabling the operator to have a complete field of vision, while protecting the operator from harmful and distracting reflections. The snap-on attachment mechanism includes first and second deformable legs having a receiving notch formed therebetween, such that the shield can be pushed on to and pulled from the probe by deforming the legs. The entire shield and snap-on connection mechanism are manufactured from a unitary piece of material which can be completely sterilized.
