About curing lights and their parts
This type holds the curing lights themselves and the parts they take: light guides, tips, barriers and batteries. The unit is a hand-held light-emitting device used to cure photoactivated, polymer-based restorative materials, and the parts matter because the light has to reach the material at the right wavelength and in the right amount. Damage to the light guide drastically decreases the irradiance a unit delivers, so routine inspection, cleaning and replacement of damaged guides are described as simple measures that preserve curing effectiveness. A built-in or separate radiometer is used to compare the unit’s output over time, including with and without an infection-control barrier in place.
Sets a light-cured material by delivering light energy, rather than cutting, cleaning or measuring anything. Powered polymerization handpieces are specifically outside the scope of ISO 14457, the standard that covers dental handpieces and motors.
