SOUSA FILHO, João Lisboa de et al. Apical leakage evaluation of endodontic cement with addition of MTA and Portland. Rev. Bras. Odontol. [online]. 2016, vol.73, n.2, pp. 135-139. ISSN 1984-3747.

Objective: The aim of this study was to evaluate the apical leakage of the AH Plus cement and AH Plus with addition of different proportions of MTA and Portland. Material and Methods: Eighty palatal roots of extracted upper permanent molars were instrumented in Reciproc System and filled with single cone. Subsequently, the roots were waterproofed and submerged in aqueous solution of methylene blue at 2%. They were then washed in running water for 24 hours and sectioned along axis for evaluation in surgical microscope. The data were submitted to Wilcoxon T test using SPSS software (p>0.05). Results: There was no statistically significant difference in apical leakage of the cements. Conclusion: In conclusion, the addition of MTA and Portland to AH Plus cementnot influenced the apical sealing.
