UAB dentist develops new filling for root canal treatments

Kyounga Cheon, DMD, M.S., assistant professor in the University of Alabama at Birmingham School of Dentistry and corresponding author of the study, found that the nanomatrix gel filling can help regenerate and heal the site better than the commonly used clotted blood to fill the canal. The new nitric oxide filling releases antibacterial properties that aid pulp regeneration and the antibiotics needed to treat the site simultaneously. 

“Root canals are common dental procedures in which infected pulp tissue is removed from the tooth, and having a bioactive therapeutic filling that can help treat and heal the pulp tissue would be of huge benefit to both the dentist and the patient,” Cheon said. “We’re hopeful that the combination of antibiotics and nitric oxide will help change the way root canals are treated moving forward.” 

Future studies will be needed to determine how effective the gel filling is with a larger sample size and how to best integrate into endodontic practice.
