Zusammenfassung: | The purpose of this study was to find a means to prevent the adhesion of carboxylate temporary cements to the abutment teeth and an easy way to remove the cements stuck to the dentin surface. At first, the effect of tannin-fluoride component in cements on adherence to abutment teeth was examined, and carboxylate cements showed strong stickiness with and without tannin-fluoride. Then experimental solvents for carboxylate temporary cement were manufactured and the removing ability of stuck cement to dentin was evaluated. Shear bond strengths of adhesive resin cements to the dentin surface treated with the trial solvent of 2.5% ammonia solution were measured. Ammonia solution showed excellent removing ability and had little influence on shear bond strength of adhesive resin cements. The treated dentin surface showed almost no change in micromorphological characteristics. The results suggested that ammonia solution is a practical solvent for carboxylate temporary cements. |
