title: Production of a nonwettable enamel surface.
abstract: A water-repellent enamel surface was achieved using a new material that is a combination of fumed silicon dioxide and a silane. The effects of this coating on enamel were studied. In vitro studies suggest that the material produces good water and saliva repellency. However, no reduction in bacterial colonization between treated and control enamel occurred. results of in vivo investigations of coated and control Styroflex strips showed a reduction in deposits on the former. Retention with or without previous acid etching of the enamel was poor.
