ABSTRACT
The purpose of this study was to analyze and compare the bond strengths between stainless steel plate and zinc phosphate cement, polycarboxylate cement and glass ionomer cement, which are frequently used for cementation of stainless steel crowns. Three cementing materials were glued to the poles standing above stainless steel plate, bovine teeth, light cured glass ionomer restorative material and amalgam. And the tensile bond strengths between them were measured with universal testing machine and the results were statistically processed using ANOVA and Student t-test. The obtained results were as follows : 1. On stainless steel plate, glass ionomer cement and polycarboxylate cement showed higher tensile bond strengths compared to zinc phosphate cement, with no significant difference between the former two. 2. On the surface of bovine teeth and glass ionomer restorative material, glass ionomer cement showed highest bond strength, followed by polycarboxylate cement and zinc phosphate cement in order. 3. For amalgam restoration, polycarboxylate cement and glass ionomer cement showed higher tensile bond strengths than zinc phosphate cement, with no significant difference between the former two.
