Abstract: Dental curing light systems capable of monitoring the degree of curing of polymerizable dental material. A monitoring light source delivers visible monitoring light at one or more different visible wavelengths and a visible light detector detects the monitoring light diffusely reflected by the polymerizable dental material. The monitoring light has a wavelength of maximum emission (λmax-mon) that does not effectively induce polymerization of the polymerizable dental material. Change in intensity of the monitoring light reflected from the polymerizable dental material is used to determine when a selected degree of curing is reached in the polymerizable dental material.
