The AgVO<jats:sub>3<\/jats:sub> was incorporated into AH Plus, Sealer 26, and Endomethasone N at concentrations 0%, 2.5%, 5%, and 10% (in mass). The antibacterial activity of freshly sealers was assessed by direct contact with<jats:italic> Enterococcus faecalis <\/jats:italic>and CFU\/mL count (n=10), surface topography, and chemical composition were measured by SEM\/EDS, and the setting time was measured by Gillmore needle (n=10). The Kruskal-Wallis and Dunn statistical tests were applied (<jats:italic>\u03b1<\/jats:italic>=0.05).<jats:italic> Results.<\/jats:italic> All groups of sealers evaluated inhibited<jats:italic> E. faecalis<\/jats:italic> (p&gt;0.05). The incorporation of AgVO<jats:sub>3<\/jats:sub> altered the atomic proportions between components of the endodontic sealers, and the percentage of silver (Ag) and vanadium (V) increased proportionally to the concentrations of AgVO<jats:sub>3<\/jats:sub>. Topography analysis showed differences in components distribution on the surface of the specimens. The sealers incorporated with AgVO<jats:sub>3<\/jats:sub> of AH Plus presented a lower setting time than the control group (p&lt;0.05). For Sealer 26 and Endomethasone N, the incorporation of AgVO<jats:sub>3<\/jats:sub> increased the setting time in relation to control group (p&lt;0.05).<jats:italic> Conclusions.<\/jats:italic> The modification of endodontic sealers by AgVO<jats:sub>3<\/jats:sub> increased the atomic percentage of Ag and V proportionally to the concentration of the nanomaterial and changed the atomic percentage of the sealer components and setting times. It cannot be affirmed that the AgVO<jats:sub>3<\/jats:sub> promote differences in the antimicrobial activity of freshly sealers, and further investigations of the antimicrobial activity of the set sealers should be carried out.<\/jats:p>","DOI":"10.1155\/2019\/4676354","type":"journal-article","created":{"date-parts":[[2019,5,9]],"date-time":"2019-05-09T19:31:06Z","timestamp":1557430266000},"page":"1-9","source":"Crossref","is-referenced-by-count":28,"title":["Endodontic
