Sealapex was compaired with a zinc oxide eugenol sealer over a 24 - wk interval to examine solubility in an in vitro situation. After obturation with gutta percha and the appropriate sealer, speciemens were immediately immersed in a saline solution to challenge the solubility of the sealers. The solutions were changed weekly to allow for a continued dissolution of the sealers. After immersed in methylene blue solution for 3 days, the speciemens were made transparent by a clearing process. Microscopic examination was used to determine the linear penetration of dye for each speciemen. Result revealed that sealapex had no greater dissolution than ZOE(P<0.05).
