Super-EBA as an endodontic apical plug.
Forty extracted human single-rooted teeth were sequentially instrumented with nickel-titanium rotary files to a size 0.36 mm at the working length. Ten teeth were randomly assigned to the two control groups. The other 30 teeth were randomly divided into three groups and were obturated by a 5-mm apical plug of either Super-EBA, IRM, or laterally condensed gutta-percha and Roth's sealer. After 2 days, and at 1 month, the samples were tested for microleakage by the fluid filtration system under 15 psi. The negative controls were used to consider the time that it took the fluid filtration system to stabilize. A one-way analysis of variance showed that, at 1 month post obturation, there was no statistical difference in the ability of the three materials to seal the apex from coronal microleakage. However, at 2 days, Super-EBA gave a significantly better seal than IRM or laterally condensed gutta-percha and sealer.
