Abstract

The aim of this study was to investigate fluid flow in dentin after restoration of carious teeth with resin composite bonded with a total-etching adhesive, with or without glass-ionomer cement lining. The roots of extracted third molars were removed and the crowns were connected to a fluid flow-measuring device. Each carious lesion was stained with caries detector dye and caries was removed using slow-speed burs and spoon excavators. Caries-excavated teeth were divided into two groups for restoration with resin composite bonded with a total-etch adhesive: (i) without lining; and (ii) lined with glass-ionomer cement before bonding. In non-carious teeth, cavities of similar dimensions were pre..
