Abstract

Use of particular cement depends on its advantagenous and disadvantageous properties. Several cements for definite cementation and one for temporary cementation, most commonly used in fixed prosthetics, were studied. The amount of salivary zinc dissolved from cement was determined by the method of atomic absorption spectrophotometry on a Pye Unicam SP 9 800 instrument, using correction of nonspecific signals by means of a deuterium lamp. Evident differences were observed in resistance of particular cements to the action of saliva, as shown by the proportions of zinc dissolved from the cements and found in the saliva.
