Reducing, by Pulse Width Modulation,the Curing Temperature of a Prototype High-power LED Light Curing Unit
Light emitting diode (LED) Light curing units (LCUs) Pulse width modulation (PWM)
2009/9/14
Third-generation LEDs have high irradiance and efficiency, but the associated temperature rise is potentially hazardous to the pulp of teeth. We evaluated, during composite polymerization, the irradia...
