Destructive Stresses in Adhesive Luting CementsDepartment of Dental Materials Science, ACTA, Louwesweg 1, 1066 EA Amsterdam, The Netherlands

Department of Dental Materials Science, ACTA, Louwesweg 1, 1066 EA Amsterdam, The Netherlands In this study, curing shrinkage stress development was monitored in a glass-ionomer and a BisGMA composite luting cement adhesively placed at film thicknesses ranging from 30 to 200 µm. The nature and magnitude of the stress development depended greatly on the formulation and film thicknesses of the lute. The thicker the layer, the faster the stress development in the glass ionomer and the slower in the composite. The contraction stress had a detrimental effect on the cohesive strength of the glass ionomer and on the adhesive strength of the composite cement.
