New Research to Cure Cavities

VirtualLIGHT-mother-with-son-brushing-teeth-Researchers at the University of Washington, U.S., have designed a convenient and natural product that uses proteins to rebuild tooth enamel and treat dental cavities.

This development could be an important process, adding to the pain-free treatments that we already perform at Mannamead Cosmetic Dental Centre.

“Remineralisation guided by peptides is a healthy alternative to current dental health care,” said lead author Mehmet Sarikaya, professor of materials science and engineering and adjunct professor in the Department of Chemical Engineering and Department of Oral Health Sciences.

The new biogenic dental products can, in theory, rebuild teeth and cure cavities without today’s costly and uncomfortable treatments.

“Peptide-enabled formulations will be simple and would be implemented in over-the-counter or clinical products,” Sarikaya said.

Tooth Decay A Problem

Although tooth decay is relatively harmless in its earliest stages, once the cavity progresses through the tooth’s enamel, serious health concerns arise. If left untreated, tooth decay can lead to tooth loss. This can present adverse consequences on the remaining teeth and supporting tissues and on the patient’s general health, including life-threatening conditions.

Good oral hygiene is the best prevention, and over the past half-century, brushing and flossing have reduced significantly the impact of cavities for many.

Natural Treatment

Taking inspiration from the body’s own natural tooth-forming proteins, the UW team has come up with a way to repair the tooth enamel. The researchers accomplished this by capturing the essence of amelogenin — a protein crucial to forming the hard crown enamel — to design amelogenin derived peptides that biomineralise and are the key active ingredient in the new technology. The bio-inspired repair process restores the mineral structure found in native tooth enamel.

“These peptides are proven to bind on to tooth surfaces and recruit calcium and phosphate ions,” said Deniz Yucesoy, a co-author and a doctoral student at the UW.

The peptide-enabled technology allows the deposition of 10 to 50 micrometres of new enamel on the teeth after each use. Once fully developed, the technology can be used in both private and public health settings, in biomimetic toothpaste, gels, solutions and composites as a safe alternative to existing dental procedures and treatments. The technology enables people to rebuild and strengthen tooth enamel on a daily basis as part of a preventive dental care routine. It is expected to be safe for use by adults and children.

Co-authors are H. Fong, a research scientist in the UW Department of Materials Science and Engineering, and Greg Huang, professor and chair of Orthodontics in the School of Dentistry.

The research was funded by the Washington State Life Sciences Discovery Fund and the UW Department of Restorative Dentistry’s Spencer Fund.

  1. This is very interesting – would this mean less work for dentists? But then I guess we could look to spend more on cosmetic dentistry.
