A bstract — The effect of various proprietary and non‐proprietary varnishes and other surface treatments on the movement of tritium out of surface‐treated tritium‐labelled glass‐ionomer cement samples was determined. Whilst no treatment reached the ideal goal of prevention of water movement for the first hour after mixing the cement, several proprietary varnishes, and two emollients when thickly applied, effected substantial reductions in the release of tritium. The results highlight the need for further development of varnishes for glass‐ionomer cements, as well as providing clinically‐relevant comparative data on available materials.
