The biocompatibility and antibacterial action of three endodontic sealers

Abstract EN

Root canal sealers are regularly used in root canal fillings.

Bacteria can multiply and grow inside the root canal system.

Materials and Methods: Twelve albino rabbits were used for the implantation of the sealer materials inside the S.C.

tissue of the animals for 3, 14 and 28 days for determination of tissue reaction.

A Muller-Hinton culture medium was used for culturing the bacterial swabs for 24 and 48 hours at 370.

Results: The ZOE sealer showed the severest inflammatory reaction initially, and all the sealer materials revealed good tendency for tissue healing after 28 days.

The Dorifil sealer exhibited the highest antibacterial action against all the microorganisms tested.

Conclusion: The endodontic sealers used in this study showed different types and severity of inflammatory reaction with good tendency for healing.

All the sealer material tested had antibacterial actio against the bacteria but with different capacities
