Abstract
The success of an endodontic material depends on its sealing ability, as most post-treatment endodontic disease usually occur due to marginal leakage in the apical area of the root canal. The aim of our study is to evaluate the sealing ability of a Mineral Trioxide Aggregate-based endodontic sealer (ProRootMTA), compared to other frequently used materials, on extracted human teeth, using a dye penetration leakage test. The results showed a significant difference (p[0.01) between ProRoot MTA and the other two sealers.
