New dental product may cure cavities

dfdfdResearchers at the University of Washington (UW), USA have designed a product that uses proteins to rebuild tooth enamel and treat dental cavities. The research finding was first published in ACS Biomaterials Science and Engineering.
The new product would be peptide-enabled formulations Lead author Mehmet Sarikaya, professor of materials science and engineering said: "Peptide-enabled formulations will be simple and would be implemented in over-the-counter or clinical products".
According to the World Health Organization, dental cavities affect nearly every age group and they are accompanied by serious health concerns.
Good oral hygiene is the best prevention, and over the past half-century, brushing and flossing have reduced significantly the impact of cavities on many people. Still, some socioeconomic groups suffer disproportionately, the researchers said.
The UW team states it has come up with a way to repair the tooth enamel. The researchers accomplished this by using 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 bioinspired repair process restores the mineral structure found in native tooth enamel. The peptide-enabled technology allows the deposition of 10-50 micrometres of new enamel on teeth after each use. Once fully developed, the technology has the potential to be used in both private and public health settings, in biomimetic toothpaste, gels, solutions and composites. The technology enables people to rebuild and strengthen tooth enamel on a daily basis as part of a preventive dental care routine.

Nicotine extracted from ancient dental plaque for the first time

dfdfdResearch from Washington State University (WSU), USA has shown for the first time that nicotine residue can be extracted from plaque on the teeth of ancient tobacco users.
Shannon Tushingham, co-author of a new study on the research in the Journal of Archaeological Science Reports said: "The ability to identify nicotine and other plant-based drugs in ancient dental plaque could help us answer long-standing questions about the consumption of intoxicants by ancient humans. For example, it could help us determine whether all members of society used tobacco, or only adults, or only males or females".
Dental plaque adheres to the surfaces of teeth and mineralises over time, preserving a wide range of substances that are in the mouth. Using modern instruments, scientists have found they can detect and characterise trace amounts of a wide variety of compounds in plaque.
Because nicotine is detectable in the dental plaque of contemporary smokers, Tushingham and her collaborators wanted to find out if it was also preserved in plaque of people who lived long ago.
She and her team collaborated with members from the Ohlone tribe in San Francisco Bay to extract plaque from the teeth of eight individuals, buried between 6,000 and 300 years ago, and analyse it for nicotine.
The WSU researchers used liquid chromatography-mass spectrometry to test the samples for nicotine and other plant-based drugs.
Among the samples they analysed, two tested positive for nicotine, demonstrating for the first time that the drug can survive in detectable amounts in ancient plaque.

Research on dolphin teeth may hold vital information on ocean pollution

dfdfdUsing teeth to gather data on ocean pollution might seem like an unlikely method; however, when the teeth involved are those of dolphins, then the idea might not seem so improbable. In new research from New Zealand, scientists from the dental faculty at the University of Otago are now doing exactly that to find the impact industry is having on the ocean ecosystem.
The study, being run by Dr Carolina Loch, is looking at metal contaminants. Dr Loch believes that the data recovered could be helpful in measuring the impact industries like mining have on the ocean.
Contaminants in marine environments are a particular health risk as they are absorbed into teeth and bones. Dr Loch said: “One of the key issues is that the wastewater from mining and city pollution goes back into the marine environment, and it comes back to us when we consume seafood”.
Dolphin teeth reliably record contamination because toxic metals and trace elements from their diet are incorporated into enamel and dentine throughout life. The teeth being used are from bottlenose dolphins, who do not migrate so Dr Loch and her colleagues from New Zealand and Australia are able to more accurately compare metal exposure in teeth from supposedly low-polluted areas in New Zealand to a high metal exposure area in South Australia. According to Dr Loch, she expects that high concentrations of toxic metals in teeth will be correlated with increased industrial contamination, while decreased levels will be in areas of improved environmental practices.
