Comparative Analysis of Microleakage Associated with Various Endodontic Sealers: An in-vitro Study

Introduction: The purpose of the root canal obturation is to provide a hermetic seal, that inhibits the microleakage and canal reinfection, thus the health of the periapical tissues can be preserved. It has been observed that the sealer used during endodontic therapy has a direct link with the longevity of the treatment and the occurrence of postoperative pain. Aim: The goal of the present study was to assess microleakage in extracted teeth of four separate endodontic sealers (AH Plus, Sealapex, MTA Fillapex, and Ceraseal) using the dye penetration method. Materials and Methods: In this in-vitro study, 84 freshly extracted single-rooted teeth were endodontically treated and obturated using four different sealers and divided into four groups along with two control groups based on the sealer used. Microleakage was checked in apical sections using the dye penetration method under the stereomicroscope. Results: The maximum dye penetration was seen in Sealapex whereas the least microleakage was shown by Ceraseal endodontic sealer. Conclusion: Maximum microleakage was seen with calcium hydroxide based (Sealapex) while the least microleakage was noticed in bioceramic based (Ceraseal) sealer group.
