title: [In vitro studies on abrasion and thickness of layers of plastic sealers].
abstract: Plastic sealers on the tooth are effective for no more than two years because of mechanical and thermal stress. Three plastics with different chemical compositions (Nuva-Seal, Alpha-Seal, and Enamite) therefore were examined in terms of abrasion. Necessary resealing results in thicker layers of sealer in the nonabrased areas, as determined with the three above-mentioned preparations. Bis-EMA type sealers satisfactorily resisted abrasion and also form the thinnest sealing layers.
