ABSTRACT
The article presents a study for examining the ability of several commercially available dentin adhesives for protection of dentin from acid etching. The study used a scanning electron microscope for investigating the materials that were placed on the prepared dentin of freshly extracted teeth. It was found that these products were not effective by themselves in the maintenance of protection for the dentinal tubules against acid attack especially the chlorophosphate ester type materials. The dentin adhesive from Johnson & Johnson was removed by acid and it opened the dentinal tubules. The combination system from Den-Mat Corp. was attacked by the acid inspite of producing a thick film. The usage of a technique and material that seals the dentin has been suggested.

    It is generally accepted that the application of dentin-enamel adhesive should involve not only the etched enamel but also the dentinal surface. For this purpose, new bonding agents requiring dentin etching and the combined use of bifunctional groups (Primers) as well as hydrophilic resins have...
