Abstract

The morphological changes produced, in vitro, by application of ferric oxalate on enamel surfaces were examined by scanning electron microscopy. Exposure of human enamel surfaces to ferric oxalate (5.3% w/w aqueous solution or added to phosphoric or citric acid) resulted in cleaned, activated enamel surfaces and a mild etching which increased surface roughness and porosity. Deposition of crystal formations occured in approximately 50% of the examined areas. Crystals bond firmly to the porous underlying surfaces and resist washing with 5, 10 or 20 ml of distilled water.
