Abstract
An improved dental procedure contacts a tooth with a fluoride carrier to produce a fluoride containing layer on the tooth. The tooth is then irradiated with UV radiation in the wavelength range of 100-400 nm. The fluoride carrier is at least 70% transparent to UV radiation, and the radiation is provided with sufficiently low energy to avoid inflicting pain on the patient.
Claims2
A method of fluoride treatment of a tooth, including the steps of:
- contacting said tooth with a fluoride-carrier to produce a fluoride containing layer therein, said carrier having the property that it does not char when irradiated by UV radiation and is at least about 70% transparent to UV radiation, and
- irradiating said fluoride-carrier with UV radiation in the wavelength range 100-400 nm, said radiation having an energy sufficiently low that the temperature of said tooth remains less than the temperature which would produce a painful sensation.
