Researchers from the University of Nottingham and the Wyss Institute at Harvard University created dental fillings that heal teeth using stem cells. No more root canals?
The team took second prize in the materials category of the Royal Society of Chemistry’s Emerging Technologies Competition this year.
Dr Adam Celiz, Marie Curie Research Fellow at the University of Nottingham, said: “Existing dental fillings are toxic to cells and are therefore incompatible with pulp tissue inside the tooth. In cases of dental pulp disease and injury a root canal is typically performed to remove the infected tissues.
“We have designed synthetic biomaterials that can be used similarly to dental fillings but can be placed in direct contact with pulp tissue to stimulate the native stem cell population for repair and regeneration of pulp tissue and the surrounding dentin. Our approach has great promise to impact the dental field and this prize provides a great platform to develop this technology further with industrial partners.”
