Scientists say they have
developed a material which could help regenerate tooth enamel – and prevent
tooth decay or sensitivity in the future.
Press
Association report continues:
Coating
the outer part of the teeth, enamel is the hardest tissue in the body and can
resist extreme temperatures and acidic food and drinks, helping it last for
decades.
But
unlike other tissues in the body, once it is lost it cannot regrow – leading to
pain and tooth loss for around 50% of the world’s population.
Researchers
at Queen Mary University of London now say they have developed a new way to
grow mineralized material, which could pave the way for regenerating hard
tissues such as enamel and bone.
Dr
Sherif Elsharkawy, a dentist and first author of the study, said: “This is
exciting because the simplicity and versatility of the mineralization platform
opens up opportunities to treat and regenerate dental tissues.
“For
example, we could develop acid-resistant bandages that can infiltrate, mineralize,
and shield exposed dentinal tubules (microscopic channels) in human teeth for
the treatment of hypersensitivity.”
The
team found a protein that is able to trigger the growth of crystals, in a
similar way to how crystals grow when dental enamel develops in the body.
Lead
author Professor Alvaro Mata said the “key discovery” had been finding a way to
exploit proteins to control and guide the process of mineralization.
“Through
this, we have developed a technique to easily grow synthetic materials that
emulate such hierarchically organized architecture over large areas and with
the capacity to tune their properties,” he added.
The experts believe their work, published in science journal Nature Communications, has the potential to be used in a variety of ways in regenerative medicine.
