SALT LAKE CITY, UT (KSL/NBC) - Using stem cells to regenerate body parts is no longer science fiction and may hold true inside people's mouths.
The new dean of the University of Utah's School of Dentistry projects regrowing teeth could become a reality within the decade.
According to Dr. Rena D'Souza, who now assumes her new role as the school's dean, "There are stem cells that lie in our adult teeth and our baby teeth, which we lose, that can be used to regenerate or regrow structures of the tooth that are lost to decay or trauma."
D'Souza sees an expanding program at the university for teaching, training and research. She believes dental research should be a collaborative effort.
The university, she said, has already established a national environment for scientific collaboration where researchers from multiple disciplines work together to discover and polish new technologies.
