Abstract

Appropriate wavelength and intensity of visible light is essential for adequate polymerization of visible-light curing composite resins. Exposure time is an important factor for polymerization of the composite resin surface, while, due to light absorption and scattering of light in the composite material, light intensity becomes the most important factor in the deeper layer, to ensure a satisfactory degree of conversion. Curing units are tested to evaluate the condition of the curing light, used in everyday dental practice in Zagreb. Eighty-three curing units were tested by the Curing Radiometer. The results revealed that 44% of the curing units have less light intensity than necessary for composite material polymerization.
