Abstract
A light curing device has a light source for curing light-polymerizable dental materials. A control circuit controls the light output of the light source according to a pre-determined output profile. The output profile has a starting time period with a decreased output relative to a maximum output, followed by a main curing time period. In the main curing time period, a pulsed output with alternating high output value and low output value is provided.
