Evaluation Of Apical Sealing Ability Of A Root Canal Sealers - An Invitro Study

Introduction: The success of endodontic treatment is complete obturation of the root canal system up to the cementodentinal junction. Obturation of the root canal is usually done with gutta-percha along with a root canal sealer. Sealers are used as binding agents, and they lubricant and aid in sealing of gutta-percha. The hermetic sealing of the root canal by means of a three dimensional obturation of the pulp space constitutes the key factor for successful endodontic therapy. Aim and objective: The aim of the present study was to evaluate and compare the apical sealing ability of three root canal sealers using dye penetration method. Materials and Methods: A sample of 30 single rooted extracted maxillary incisors teeth were collected and kept in saline and preserved. The coronal portion of teeth was prepared at cemento-enamel junction using step back technique. The canals were then obturated by lateral condensation method with any one of the sealers AH plus, iroot SP sealer & Zinc oxide eugenol sealers.Dye leakage method with methylene blue was used to evaluate sealing ability. Results: Microleakage was noticed in all the groups, iRoot SP sealer showed the least apical microleakage followed by AH plus & Zinc oxide eugenol. Conclusion: The present study was undertaken to evaluate in vitro, the apical sealing ability of three different root canal sealers, and i Root Sp sealer showed the least apical microleakage.
