It is called a curing light. It's just a concentration of light that can be directed in a small area. Some types of cement must be light cured in order for it to harden.
What are those neon light things the dentist uses when sealing the cement on your crowns?
I call them light curers but I'm not sure that's their proper name. They have an LED which shines a high intensity 470 nm light at the cement. This causes a chain reaction in the cement chemically altering it thereby causing it to set.
Reply:I think it's to help seal the cement or something but I do know that if the dentist and the assistant get to wear the UV glasses, than shouldn't I be hooked up with a pair?
Reply:Black guinea pig is the stupid one ! And no insults please from the ignorant 'cos it is intense UV. (ultra violet light) to set the cement rapidly.
Reply:UV light to set the cement.
