The study aimed to investigate dentists’ exposure to curing light and to obtain information about the dentists’ knowledge on practical use and technical features of their curing lights as well as their safety awareness.

A study was performed to assess 13 different eye protection filters, glasses and shields, intended for use with dental material light curing procedures as a follow-up to a similar investigation in 2006. To assess the safety and efficiency, spectra of curing lamps and filters were measured using a spectroradiometric instrument and integrating sphere.
