King’s School London researchers have found that keratin—a protein present in hair, pores and skin and wool—can restore tooth enamel and arrest early decay by forming a protecting, enamel-like coating.
Their research, printed in Superior Healthcare Supplies, discovered that when keratin extracted from wool is utilized to the tooth and comes into contact with minerals in saliva, it builds a extremely organised, crystal-like scaffold that mimics pure enamel construction and performance. Over time, the scaffold attracts calcium and phosphate ions, selling the expansion of a protecting enamel-like layer.
In contrast to bones and hair, tooth enamel can’t regenerate, so this represents a major breakthrough in regenerative dentistry. Researchers consider keratin remedy could possibly be delivered as a day by day toothpaste or as knowledgeable gel utility, doubtlessly obtainable to the general public in about two to a few years.
‘So simple as a haircut’
“We’re getting into an thrilling period the place biotechnology permits us to not deal with signs alone however to revive organic operate utilizing the physique’s personal supplies. With additional improvement and the best business partnerships, we might quickly be rising stronger, more healthy smiles from one thing so simple as a haircut,” says Dr Sherif Elsharkawy, senior writer and prosthodontics advisor at King’s School London.
In the meantime, PhD researcher Sara Gamea, first writer of the research, provides: “Keratin presents a transformative various to present dental therapies. It’s sustainably sourced from organic waste like hair and pores and skin and removes the necessity for plastic resins generally utilized in restorative dentistry, that are poisonous and fewer sturdy. It additionally extra carefully matches the pure tooth color.”
As issues enhance over healthcare sustainability and long-term fluoride use, keratin emerges as a promising, biodegradable various that faucets round economic system ideas and turns waste right into a health-promoting useful resource.
