The objective of this investigation was to evaluate in vitro, the coronal microfiltration of two types of cements –zinc oxide-eugenol/silicone- using the obturation technique with lateral condensation. For this, 60 single-rooted teeth were used of recent extraction, to which the anatomical crown was sectioned to them; all the pieces were prepared crown-apical with gates-glidden drills and soon they were used Flex-o-file files with the step-back technique; the pieces were distributed at random in two groups: one of 30 pieces were obturated with cement sealant with zinc-eugenol oxide (ENDOFILL®) in conjunction with laterally condensed gutta-percha, and another group of 30 pieces were obturated with cement sealant with silicone (Roeko Seal Automix®) using the same technique. The samples were covered by varnish of nails in all the extension by the root, except in the coronal part and soon they were introduced in Chinese ink by 21 days for the entrance of the same one by passive filtration. The samples by fracture were sectioned to observe the coronal microfiltration of the Chinese ink, registering digital photographies of high precision. The coronal microfiltration was registered using the program Corel Draw X3. In order to analyze the data statistically, the test was used t-student with which it determined that significant difference between the training groups exists One concludes that the teeth obturated with the cement sealant with silicone displayed minor coronal microfiltration, in degrees and millimeters, that the samples obturated with the cement sealant with zinc oxide - eugenol.
