If ive read correctly an article about it said it operated in the 200nm - 400nm range
200nm is hard UV or UVA. I seriously hope that the light source they ae using for hardening is above this.
btw, did you happen to smell ozone when they were curing your teeth?
Ozone is a byproduct of hard UV slamming into 02 and N2 creating an extra charged bond.
Nozone or nitrous ozone has a distinct smell.
