Sealability of MTA and calcium hydroxidecontaining sealers

Abstract

ObjectivesThe aim of this study was to evaluate the apical sealability of Fillapex®, Endo-CPM-Sealer® and Sealapex®. Material and MethodsNinety-four freshly extracted single-rooted teeth were selected and decoronated. All teeth were radiographed to confirm the existence of a single and straight root canal, which was prepared using Protaper Universal and 2.5% sodium hypochlorite. The teeth were randomly divided in groups of 10 specimens each according to the sealer, and the canals were filled using the single cone technique and one of the sealers. Four additional teeth were used as controls. The teeth were submitted to dye leakage with Rhodamine B for 24 h but using vacuum on the initial 15 min. Thereafter, they were cut longitudinally and the leakage was measured in a linear fashion from apex to crown. Data were analyzed by ANOVA and Tukey's tests at 5% significance level. ResultsFillapex® and Sealapex® showed significantly less dye leakage than Endo-CPM-Sealer® (p<0.05). ConclusionsIt was concluded that Fillapex® and Sealapex® were able to prevent apical dye leakage differently from Endo-CPM-Sealer®.

“…), and Endo CPM Sealer, which failed to prevent apical leakage (Gomes‐Filho et al . ). MTA has also been mixed with a water soluble polymer, which resulted in a material with improved properties and was suitable for use as an endodontic sealer cement with radiopacity greater than the 3 mm thickness of Al specified by the international standard (Camilleri ) and good dimensional stability (Camilleri & Mallia ).…”

“…) and sealing ability (Gomes‐Filho et al . ) have been investigated, but there is still a lack of information about the physicochemical and mechanical properties of MTA Fillapex.…”

“…Trabalhos, como os de Jacobson et al 9 (2002), Miletić et al 10 (2002) e Gomes-Filho et al 11 (2012), demonstram que somente a obturação de canal, após o tratamento endodôntico, não é o suficiente para impedir a penetração de microrganismos até a região periapical, permitindo a percolação ou a microinfiltração coronária, resultando na recontaminação dos tecidos periapicais.…”
