A Novel Fast-setting Root Canal Filling Material

Abstract/Technology Overview

Mineral trioxide aggregate (MTA) has been successfully used in endodontic applications because of its unique biocompatibility, antibacterial nature, seal ability, and its capacity to promote hard tissue formation. However, MTA is difficult to use for practitioners because of its properties of granular consistency, long setting time, initial looseness, and unexpected discoloration.

Granular form of MTA at the initial stage of blending makes the material hard to aggregate. While a long setting time could result in the tissue or blood washing away the MTA during the operation. Thereby influencing the sealing property and treatment effect.

This technology presents a new MTA technology, which contains a mixture of modified root canal filling material with patented setting accelerators, that has superior setting time and handling properties compared to common MTA cement.

Technology Features, Specifications and Advantages

This technology can be activated by the addition of water drops to form a putty. The putty can be injected before the root canal is plugged. Furthermore, this technology carries the following features:

  • Setting time of 15 minutes
  • Seals better than current available MTA cement
  • Cell proliferation through improved biocompatibility
  • Passes the requirements of radiopacity standards as per ISO6876
  • Improved appearance with no issues on discolouration

Potential Applications

This technology has been developed for use in dental and orthopaedic applications such as:

  • Endodontic treatment
    • A root end filling material for apexification
    • Pulpotomy of primary teeth 
  • High strength bone cement for replacment of PMMA
  • Bone void filler

Customer Benefit

This novel root canal filling material with enhanced properties of short setting time for one-visit endodontics, superior clinical manageability, and no discoloration.
