Abstract: Purpose: This in vitro study evaluated the influence of zinc oxide-eugenol temporary cement(ZOE-TC) on the sealing ability of composite restorations using two adhesive systems. Methods: Standard Class V cavities were prepared in 20 bovine incisors and restored with either ZOE-TC (IRM) or eugenol-free cement (Cavit®) (n=10/temporary cement type). After 7 days, five teeth per material group were restored using Single Bond(SB) and five using Adper Prompt(AP). The cavities were filled with composite (Filtek Z-250), thermal cycled (500 cycles),immersed in basic fuchsine solution, and longitudinally sectioned. Dye penetration was evaluated using optical-microscopy and scored. Data were analyzed by Kruskal-Wallis test (P = 0.05). Results: Overall, leakage in dentin was similar to that in enamel. In enamel margins, only the group with Cavit cement associated with AP presented significant higher leakage. In dentin margins, AP exhibited higher leakage than the groups restored with SB; there was no significant difference between eugenol-free cement and ZOE-TC. Conclusion: In general, SB showed better marginal sealing than AP, and ZOE-TC did not increase dye leakage. Eugenol in the temporary cement did not affect the marginal sealing of adhesive restorations.
