COMPARATIVE STUDY BETWEEN THE ZINC PHOSPHATE CEMENT AND RESIN CEMENT: LITERATURE REVIEW

Abstract

The cementing agents are materials used to seal the interface between prosthesis’s surface and dental substrate, providing retention, resistance to the restoration and marginal sealing, promoting longevity and predictability of indirect restorations. Although literature has several cements, the commonly used are zinc phosphate cement and resin cements. In this context, know the physical and chemical properties of these materials it is essential for a correct clinical application. The study aimed to compare the zinc phosphate cement properties and resin cement through literature review in order to test the null hypothesis that there is no difference in the longevity of the rehabilitation between zinc phosphate cement and resin cement, when indicated correctly. The literature search was conducted in PubMed, Scielo and Google Scholar, in the period between 1999 to 2015. The keywords used were: dental cements, resin cements, cement, resin cement, dual-cured resin cement, adhesive cements and phosphate zinc. After application of the inclusion and exclusion criteria 26 articles were selected. It is concluded that the resin cement is the cementation material that has superior properties compared to zinc phosphate cement. However, due to its high cost, it is not the first material of choice for cementation of metal parts. Although the zinc phosphate cement presents some limitations when well indicated it does not diminish the longevity of restorations.
