Abstract:

BACKGROUND: In esthetic restorative dentistry, light-cured resin composites are widely applied in direct repairing dental defects due to their excellent color performance. 
OBJECTIVE: To review research status of influencing factors on the opalescence and fluorescence of light-cured resin composites.
METHODS: Databases of CNKI and PubMed were retrieved by the first author to research the papers with the key words of “resin composite, illumination, filler, scattering, opalescence, fluorescence, color”. Papers underlying light mechanism, characteristics, and research status were included. In total 129 documents were initial searched, and 34 ones were included in the final analysis.
RESULTS AND CONCLUSION: The light-cured resin composites, in particular, scattering of inorganic filler with similar diameter to blue light and absorption of photoreceptive organic matrix to ultraviolet light, have similar properties of opalescence and fluorescence as those of natural teeth. Opalescence and fluorescence of light-cured resin composite were affected by illumination, resin composition and relevant clinical performances, which may further influence the masking effect of resin composites.
