A new heat sink has been designed that increases the run time of a cavity-filling resin-curing or teeth-bleaching dental device with light emitting diode. The heat sink is a hollowed copper object that is filled with a phase change material. Computational simulations and experimental measurements are presented that show the heat sink with phase change material increases the run time of the device beyond the minimum requirement of six minutes.
