Fluoride release from light-cure liners/bases: an eight-month report

Five new visible light-cure cavity liners/bases that contain fluoride were evaluated for fluoride release over an 8-month period. Fluoride was released from all the materials but decreased significantly over the test period. There was also a significant difference in the amount of fluoride released between the materials. At 8 months, only XR Ionomer and Vitrabond were releasing detectable fluoride, with XR Ionomer releasing significantly more.
