The illumination is provided by a cold light source (5), e.g. a light-emitting diode, to produce light of the appropriate wavelength for curing the filler near the light exit point, as well as illumination light. This is located in close proximity to the light exit point (4). Power is provided by batteries (3) housed in the handle (1), together with an operating switch (6). Alternately a separate power source can be provided, with a cable bushing being provided in the handle.
