It has been proposed that one of the causes of failure on the channels treatment is the bacteria passing through the apical foramen, which by direct action or by activation of the immune system generates an inflammatory response. The apical sealing using a suitable sealing technique and sealant cement is what prevents the passing through of these bacteria, but in presence of humidity, it suffers of solubility and allows bacterial filtration. The objective of this research was to evaluate and compare the bacterial apical microfiltration that occurs after root filling using three techniques of obturation, and three endodontic cement, for which an experimental type study was used where 90 unirradicular teeth were selected, which were instrumented with Wizard Navigator files up to 40 Conicity file 0.06, being irrigated permanently with 4.9% Sodium Hypochlorite. The teeth were randomly divided into three groups that were obturated using Single Cone(n= 30), Lateral Condensation(n = 30) and Tagger`s hybrids (n = 30) using in each group the three endodontic cements: EndoFill (n = 10), Sealapex (n = 10) and AH Plus (n = 10). The outer surface of each tooth was glazed with nail polish, except 3 mm. Of the apical part and they were mounted in a device for bacterial filtration, leaving the apexes submerged in Blue of methylene mixed with distilled water (1 to 1) at a temperature of 37º in an incubator for 6 days; after this process, the root enamel was cleaned with 2% acetone and the teeth were submitted to a Diaphanization process, in order to measure the microfiltration in a stereomicroscope. The results found by the Tukey Test showed a significant difference from the Tagger Hybridized Shutter Technique (20.83 mm) compared to the Single-Cone (68.3 mm) and the Lateral Condensation (91.26 mm). About the cements, the one that showed smaller microfiltration was the cement based on Epoxy Resin AH Plus (21.66 mm) against the cements based on Calcium Hydroxide Sealapex (68.26 mm) and based on Zinc Oxide and Eugenol EndoFill (90.46 mm). Accordin to the ANOVA Test, it is concluded that both the technique of obturation (p= 0.0025) and endodontic cement (p= 0.0032) had influence on the microfiltration, being the Tagger Hybrid technique along with the endodontic cement AH Plus, which presented lower microfiltration To the other technical-cement associations.
