ABSTRACT:
An apparatus for providing controlled flashes of radiation, including a handpiece within which is mounted a gaseous discharge tube and a light pipe for conducting the radiation, enabling it to be directed into an oral cavity to effect in situ curing of radiation polymerizable resins used as dental restoratives. The apparatus further includes electrical circuitry for producing a train of a fixed number of relatively constant intensity flashes each time a switch is closed, and for disabling the apparatus after the flash tube has been discharged a predetermined number of times, thereby preventing unsatisfactory performance resulting from a fall-off in intensity due to aging of the tube.
