Researchers have developed a 3D printing-inspired process to engineer artificial blood vessels in teeth. The advancement may effectively regenerate the function of teeth in patients undergoing root canal treatment.<br/><br/>Root canals are effective in saving infected teeth but this age-old procedure may cause teeth to become brittle and susceptible to fracture over time. <br/><br/>Assistant professor at Oregon Health and Science University in the US, Luiz Bertassoni said, the latest procedure removes infected dental tissues and replaces them with synthetic biomaterials covered by a protective crown. <br/><br/>This process eliminates the tooth's blood and nerve supply, rendering it lifeless and void of any biological response or defence mechanism.
