CECHELLA, Bruna Casagrande et al. Ex vivo evaluation of coronal leakage in root canals filled with MTA FILLAPEX and AH Plus. Rev. Bras. Odontol. [online]. 2014, vol.71, n.2, pp. 139-143. ISSN 1984-3747.
The aim of this study was evaluate the coronal leakage in root canals filled with AH Plus and MTA FILLAPEX. Thirty single-rooted premolars were randomly divided into two experimental groups (n = 15) according to the sealer used: G1: MTA FILLAPEX and G2: AH Plus. The dye leakage test ink was conducted under pressure of 60 kPa for 8 min. After diaphanization, the dye penetration was evaluated by root thirds. Results: Eight samples form G1 and seven samples from G2 showed infiltration. In any sample from G2, the dye reached the apical third. In four samples from G1, the dye was visualized in the apical third. The AH Plus showed a superior sealing quality of the MTA FILLAPEX.
