<p>A dental curing light (100) has a control panel (114) so that one or more programmed pulsed light modes in which the light emits a series of light pulses of predetermined duration may be selected. The result is more extensive and harder curing of a curable dental composition compared to continuous exposure to light over the same time period as the pulsed light. The light pulses may have a predetermined duration in a range of about 1 to 4 seconds (e.g., 2 seconds), separated by pauses where no light is emitted with a duration in a range about 1 to about 4 seconds (e.g., 2 seconds). The end result is more complete and harder curing of the dental composition even though the dental composition is exposed to less total light.</p> |
