A new approach to anchor teeth back in the jaw using stem cells has been developed and successfully tested in the laboratory for the first time by researchers at the University of Illinois at Chicago.
The new strategy represents a potential major advance in the battle against gum disease, a serious infection that eventually leads to tooth loss. About 80 percent of US adults suffer from gum disease, according to the National Institute of Dental and Craniofacial Research.
Researchers in UIC’s Brodie Laboratory for Craniofacial Genetics used stem cells obtained from the periodontal ligament of molars extracted from mice, expanded them in an incubator, and then seeded them on barren rat molars. The stem cell-treated molars were reinserted into the tooth sockets of rats.
