The tensile bond strength of three types of resin cements to dentin were measured in a control group and after the application of two types of temporary cement. Scanning electron microscopy and energy dispersive x-ray spectoscopy were used to confirm the presence of temporary cement remnants. Overall results suggest that temporary cement application significantly decreased the tensile bond strength in all adhesive systems (P = 0.0001, analysis of variance). Scanning electron micrographs presented granula elements on the dentin surfaces treated with temporary cement even after preconditioning. Energy dispe rsive x-ray spectroscopy results shoed the presence of zinc peaks in the specimens that was not present in the control. AID - 848101
