Elastomeric Polyurethane Sealer

New root canal sealer can more thoroughly fill gaps during root canal treatment compared to commercial sealants.

Invention Summary:

Root canal sealers are essential for filling gaps during treatment, but shrink upon setting, leaving undesirable gaps that promote infections.

Rutgers University researchers have developed Elastomeric Polyurethane Sealer (EPS), an expandable biomaterial tailored for root canal treatment. EPS surpasses previous sealants by seamlessly filling the root canal space without impacting the tooth structure, preventing gaps and enhancing infection prevention. It remains resistant to shrinkage, preserving the treated tooth's integrity and exhibiting potent antimicrobial properties. With an estimated 25 million annual root canal procedures, EPS is a groundbreaking advancement empowering dental professionals to deliver unparalleled outcomes, reducing infection risk and setting new benchmarks for excellence. Witness the transformative power of EPS as it revolutionizes root canal treatment by eliminating gaps, minimizing shrinkage, and setting a new infection control standard, promising enhanced patient care and improved long-term oral health.

Market Applications:

  • Root canal treatment
  • Temporary filling material
  • Core obturating material


  • Competitive performance. This is the first expandable dental sealer that creates a complete seal.
  • Safe, quick, and easy to use material.
  • More affordable. Material lasts longer than other sealants, therefore fewer visits for patients.
