Dentin Adhesion and Microleakage of a Two-Paste Resin-Based Calcium Phosphate Cement



Sabine H. Dickens, S R. Kelly


A two-paste resin-based Ca-PO4 cement was examined for microleakage and shear bond strength (SBS). For microleakage, dentin cavities (Group A, no acid conditioning; Group B, with acid conditioning) were restored with the cement, or with VLC Dycal (Group C). After thermocycling, the microleakage was evaluated by AgNO3 staining. For SBS, metal irises secured on dentin that was treated as for the microleakage test were filled with the Ca-PO4 cement or VLC Dycal . These specimens were tested after 1 week water storage. Kruskal-Wallis One-Way ANOVA on Ranks and Tukey's post-hoc test (p < 0.05) indicated that H3PO4-conditioning did not significantly change the dentin microleakage or SBS. Both median microleakage scores and SBS values of the groups treated with the Ca-PO4 cement were significantly improved over those treated with VLC Dycal .
