Abstract

The mechanism of bonding resin to enamel is the formation of resin tags into the microporosities created by the acid. Critical-point drying (CPD) was essential for etched-dentin preservation and for resin-dentin interface observation. The microporosities created by the dissolution of the hydroxyapatite by the etchant are not evident by direct scanning electron microscopy (SEM) observation, unless the specimens are kept in a humid temperature, fixed and critical point dried, which is a time-consuming process.
