Potassium oxalate is gaining popularity as a dentin treatment to prevent the development of dentin sensitivity. Because treated dentin surfaces are covered with calcium oxalate crystals, the bond strength of cements to oxalate-treated dentin required investigation. This study determined the tensile bond strengths of glass-ionomer, polycar{ballot box}ylate, and zinc phosphate cements used to cement castings to dentin treated with either water or potassium oxalate. The results indicate that oxalate-treated dentin did not affect the bond strength of glassionomer or polycar{ballot box}ylate cements, but produced a large decrease in the bond strength of zinc phosphate cement.
