Abstract

Glassy coatings are made by curing in situ a coating of a sol gel of tetraethoxysilicon, water, alcohol, and the alkoxides of: Al, Ti and Na; or of Na and Zr. The coating may be applied to teeth as a dental fissure sealant or varnish to protect restorations, or (if filled) as an inherently coloured cosmetic coating, or as a prophylactic coating.
