We developed a dental temporary luting agent by PEMA, anetol and eugenol. This study was observed the residue of the trial temporary luting agents on abutment materials. The bond strength of the luting cements for the abutment materials after removing the trial temporary luting agents. Therefore, in this study was to examine the influence of the trial agents on cytotoxicity to human fibroblasts. As to trial agents, it entirely stuck to the resin block side with no residue on the abutment materials. The bond strength of luting cements and abutment materials when the trial agent was used showed a larger value than when the comparison temporary luting agents were used. In the cytotoxity test of fibroblasts cell, the trial agent was showed significantly larger the exist rate than the comparison materials.
