Abstract
The application of energy dispersive X‐ray fluorescent analysis (EDXRF) for the determination of elements released from five different dental luting cements such as Zinc Polycarboxylate (Carbchem), Zinc carboxylate (Adhesor Carbofine), Glass ionomer (Meron), Resin cement (Duo‐cement kit), and Carboxylate (Durelon) in artificial saliva is described. The equipment used for this study is a Si(Li) detector, a multichanel analyser, an amplifier and 55Fe and 241Am radioisotope sources. The physical basis of the analytical method used the procedure of sample preparation and results are presented. The detected elements were Cl, P, K, Ca. The results show high concentrations of Ca being released from dental cements in artificial saliva. Chemical disintegration of dental cements can adversely affect their long‐term performance. Fixed prosthodontic restorations cemented with carboxylate cement (Durelon) may be capable of withstanding long‐term clinical use compared to other agents. This material showed the highest resistance to dissolution or disintegration.
