Description
Researchers use 3D-inspired printing process: to create new blood vessels in the teeth.While root canals are effective in saving a tooth that has become infected or decayed, this old procedure can cause the teeth to become fragile and susceptible to fractures over time. Now, OHSU researchers in Portland, Oregon, have developed a process by which new blood vessels can be designed in the teeth, creating better long-term results for patients and physicians. More than 15 million root canal treatments are performed annually in the United States. The current procedure involves the removal of infected dental tissues and replacing them with synthetic biomaterials covered by a protective crown.This process eliminates the blood supply and nerve of the tooth, making it lifeless and without effect of any biological response or defense mechanism. Without this functionality, adult teeth can lose much sooner, which can result in much greater concerns, such as the need for dental prostheses or dental implants, lead researcher Luiz Bertassoni, DDS, Ph.D., assistant professor of dentistry Restorer at the OHSU Faculty of Dentistry, and assistant professor of biomedical engineering at the OHSU School of Medicine. To address this issue, Bertassoni and his colleagues used a 3D-inspired printing process based on their earlier works to fabricate artificial capillaries to create blood vessels in the laboratory.#Investigators #3Dinspiredprinting #newbloodvessels #teeth #biological #teacher #researcher #lab #protection #ymascience
