Objective: The aim of the present study was to evaluate the influence of a base on coronal microleakage of post-prepared teeth. The objectives are to compare the degree of coronal microleakage of apical fill of post-prepared teeth with and without the use of zinc oxide eugenol (ZOE) cement base, using scanning electron microscope. Materials and Methods: Sixty maxillary teeth were divided into three groups, post-space was prepared, and coronal micro-leakage checked by using methylene blue dye in three groups: (1) with ZOE, (2) without ZOE, (3) sticky wax. Results: The leakage of methylene blue dye observed was minimum in Group A (both linear and lateral), moderate to severe in Group B, and least in Group C. Conclusion: The leakage of methylene blue dye was minimum with 2 mm of ZOE base. Hence, it is always advisable to have some sealing between the post- and gutta-percha.
