Teeth

By investigating the genetic underpinnings behind tooth formation in early human development, a team of scientists in Japan has uncovered clues about how they might be regenerated in adults suffering from congenital conditions.

Earlier this year, paleontologists discovered that Spinosaurus was the first water-dwelling dinosaur. Now some of the same team has found further evidence, with a deposit of teeth recovered from an ancient riverbed, far outnumbering land dinosaurs.

Be thankful you didn’t live 20 million years ago, when the seas were patrolled by the Megalodon. This monstrous prehistoric shark was more than twice the size of a great white, and now a new detailed analysis has found just how big it really was.

Although cavities are caused by bacteria, simply killing all of the bacteria in the mouth isn't a good idea, as some of them have beneficial effects. A nanoparticle coating, however, could someday prevent cavities without harming bacteria.
-
A new method for determining the sex of human remains based on proteins extracted from tooth enamel has proven more reliable than those based on DNA or bone anatomy.

A new study is suggesting signs of the disease ALS may be detectable in teeth, decades before the onset of any symptoms. The research points to a dysfunction in metabolizing metals as a possible factor in the onset of this still mysterious disease.

After an orthodontist has fitted a patient with braces or otherwise worked on straightening their teeth, it's important for them to follow that person's progress. A new setup lets them do so, without requiring the patient to visit their clinic.
-
Tree rings hold clues to the plant's past – and your own teeth might do the same. Scientists have found that the material in the roots of teeth preserves a lifelong record of stresses on the body, such as childbirth, illness, and even prison time.

A study has offered the first insights into the long-term effects a chlorhexidine mouthwash has on the oral microbiome. The research suggests it can alter the oral microbiome, lower saliva pH increasing acidity and heighten risk of tooth damage.
-
For many cavity-prone people, tooth-brushing often just isn't enough. It was with such folks in mind that a new mouthwash-based system was recently developed, which reportedly uses light to kill problematic bacteria.
-
A new study has found a plaque-identifying toothpaste can potentially lower levels of systemic inflammation – which has been linked to cardiovascular disease, stroke and hypertension – by improving a person’s brushing efficacy.

Fillings are essentially the only treatment option widely available for cavities, but now researchers from China have created a new peptide-based coating that can prevent cavities from forming.
