ABSTRACT:
An apparatus which can be used for exposing a light-curable dental composition to a curing light to harden the composition while the composition is applied to teeth so that the exposure of dentists' or technicians' eyes to such light is minimized. The apparatus has an opaque cylindrical receptacle which is open at its top and bottom. The bottom opening allows the receptacle to pick up and discharge the dental composition. The working end of an elongated plunger, having a clear plastic core and an opaque surface coating, extends through the top opening of the receptacle, and the other end of the plunger is connected to a source of curing light. The working end of the plunger can irradiate the dental composition within the receptacle with the curing light and can also be moved within the receptacle to force the irradiated dental composition outward of the bottom opening in the receptacle onto a tooth.
