Abstract
The adhesion of acrylic composite restorative materials to etched dental enamel is increased by a factor of two or more when the enamel is coated with a thin layer of vinylbenzyl phosponic acid (VBPA) prior to forming the enamel-restorative bond. The present results support the suggestion that the enhanced adhesion is attributable to bonding between calcium ions in the enamel surface and phosphonate groups in the VBPA.Keywords
