ALVES, Flávio Rodrigues Ferreira et al. Antimicrobial activity of three temporary endodontic coronal sealers. RGO, Rev. gaúch. odontol. (Online) [online]. 2013, vol.61, n.3, pp. 307-312. ISSN 1981-8637.

Objective The object of the present study is to analyze, in vitro, the antimicrobial activity of three temporary endodontic coronal sealers. Methods The materials tested were Tempo® (Vigodent, Rio de Janeiro, Brazil), IRM® (Dentsply, Petrópolis, Brazil) and Coltosol® (Vigodent, Rio de Janeiro, Brazil). The agar diffusion method was used for this analysis. Nine plates containing the agar blood culture medium were inoculated with human saliva and in each plate three equidistant cavities were made and filled with one of the materials tested. Two plates were not inoculated and served as the negative control of the culture medium. All the plates were incubated in bacteriological incubators, in aerobiosis, for 48 hours, at 37oC. The inhibition halos of bacterial growth were measured in millimeters. Results Tempo® (Vigodent, Rio de Janeiro, Brazil) did not show a inhibition halo of bacterial growth in any of the nine plates. Coltosol® (Vigodent, Rio de Janeiro, Brazil) produced halos in all plates, and IRM® (Dentsply, Petrópolis, Brazil) in 4 out of 9 plates. In all the tests, the halos produced by Coltosol® (Vigodent, Rio de Janeiro, Brazil) were more pronounced than the ones produced by IRM® (Dentsply, Petrópolis, Brazil) (p<0.05). The temporary coronal sealer Coltosol® (Vigodent, Rio de Janeiro, Brazil) presented the most prominent antimicrobial activity, followed by the temporary coronal sealer IRM® (Dentsply, Petrópolis, Brazil). Conclusion Among the materials tested, it was concluded that the Coltosol® (Vigodent, Rio de Janeiro, Brazil) presented the highest antimicrobial activity.
