FREITAS, Gillian Costanti et al. Radiopacity of 4 cements obturators through the tomographic analysis. Rev. Assoc. Paul. Cir. Dent. [online]. 2012, vol.66, n.1, pp. 36-41. ISSN 0004-5276.

This work aims to analyze the radiopacity of the following sealers: AH Plus, Sealer 26, MTA Filappex and N-Rickert, since it is adesired property in endodontic sealers, because through it we look to the correct completion of the root canal. For this analysis, we made samples of each sealer according to the specifications of ANSI / ADA and use of computed tomography in innovative ways, comparing with the lead through the Hounsfield scale. The MTA and AH Plus sealer Filappex are more radiopacity than N-Rickert and Sealer 26, therefore, better visualization of the root canal filling.
