||Evaluation of eye protection filters for use with dental curing and bleaching lamps
||June 2007, Vol.4, No.6, p.432-439. Illus. 19 ref.
||Exposure to intense radiation sources in dental practices necessitates the use of eye protective filters to avoid blue-light photochemical retinal hazard. This study assessed whether the filters protect sufficiently against retinal hazards throughout the workday. Visible light transmittance of 18 protective filters was measured. These products consisted of spectacles, stationary lamp shields and a hand-held shield intended for use in dental practice. Nine of the 18 tested filters had adequate filtering capacity according to current lamp technology and exposure limit values. These filters transmitted less than 0.1% of the radiation of wavelengths between 400nm and 525nm. Seven of the nine filters showed transmission values below the detection limit in the wavelength band between 400nm and 500nm. Other findings are discussed.
