Professor Luiz Bardessono and his team published the breakthrough in Scientific Reports. He leads The Bertassoni Lab at Oregon Health and Science University and the Bioengineering Laboratory in the University of Sydney Faculty of Dentistry.
While current root canal therapy is effective in saving an infected or decayed tooth, the procedure may cause teeth to become brittle and susceptible to fracture over time.
Based on previous work fabricating artificial capillaries, the researchers placed a fibre mould made of sugar molecules across the root canal of extracted human teeth and injected a material similar to proteins found in the body filled with dental pulp cells.
The researchers removed the fiber to make a long microchannel in the root canal and inserted endothelial cells (cellls that are involved in filtering gases, fluid and molecu…
