Sealing ability of four interim restorations are compared with use of methylene blue dye. Sixty freshly extracted human teeth divided into four groups were used. Access cavities were prepared, canals instrumented, and cavities sealed using either Cavit, Zinc Oxide Eugenol , Zinc - Oxyphosphate , and Polycarboxylate cement. Cavit demonstrated the highest rating of marginal seal for access cavities. Zinc oxide Eugenol and Zinc Oxyphosphate cement showed much leakage. Polycarboxylate showed highest degree of marginal percolation among the tested materials.
