Objectives: The objective of the present study was to evaluate in vitro film thickness of two endodontic sealers containing epoxy-resin and zinc-oxide-eugenol, respectively in the apical region of the root canal system. Materials and Methods: A total of 20 palatine roots of the first maxillary molars were submitted to instrumentation up to a #40 file by the step-back technique and irrigated with 2 ml of NaOCl after each change of file. The roots were divided at random into two groups of 10 elements; one group was sealed with the Sealer 26® cement and the other one with the EndoFill cement using the classical technique. The roots were abraded in the apical region until exposure of the filling and cut crosswise at 3 mm to obtain samples. The samples were analyzed by optic microscopy with 40X magnification. The images obtained were recorded using the Adobe Premiere 5.1® software and submitted to morphometric analysis using an integration grid that permitted the quantification of the area filled with the sealer or gutta-percha, and eventual empty spaces. Results: Statistical analysis of the data (Kruskal-Wallis test, P ≤ 0.05) revealed no significant differences between the epoxy-resin-based cement Sealer 26® (47.85%) and the zinc- oxide- eugenol-based cement EndoFill® (54.16%). Conclusion: We conclude that the two sealers tested showed a similar behavior regarding the cement film thickness in the apical region
