Getting a proper cure of light-cured dental materials can mean the difference between lasting success with a case and a dissatisfied patient. Dental LED curing light technology has advanced quickly in recent years with wide light wavelengths capable of curing the full range of innovative dental materials, but proper calibration is still critical. The lights compared here feature built-in radiometers which make it easier to calibrate to ensure the correct amount of energy is being applied to the material during the cure.
