Sealability of MTA and calcium hydroxidecontaining sealers

Objectives

The aim of this study was to evaluate the apical sealability ofFillapex^®, Endo-CPM-Sealer^® and Sealapex^®.

Material and Methods

Ninety-four freshly extracted single-rooted teeth were selected and decoronated.All teeth were radiographed to confirm the existence of a single and straight rootcanal, which was prepared using Protaper Universal and 2.5% sodium hypochlorite.The teeth were randomly divided in groups of 10 specimens each according to thesealer, and the canals were filled using the single cone technique and one of thesealers. Four additional teeth were used as controls. The teeth were submitted todye 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 linearfashion from apex to crown. Data were analyzed by ANOVA and Tukey''s tests at 5%significance level.

Results

Fillapex^® and Sealapex^® showed significantly less dyeleakage than Endo-CPM-Sealer^® (p<0.05).

Conclusions

It was concluded that Fillapex^® and Sealapex^® were able toprevent apical dye leakage differently from Endo-CPM-Sealer^®.
