Researchers have developed a python-tooth-inspired device as a supplement to current rotator cuff suture repair, and found that it nearly doubled repair strength. Their biomimetic approach following the design of python teeth helps to...
A new study has revealed the hidden emotional challenges patients go through following tooth loss. Patients highlight feelings of self-consciousness, shame or fear as well as physical sensations such as pain and sensitivity and worries...
Although periodontitis is an extremely prevalent disorder, it is challenging to conduct detailed and comprehensive analyses of its progression at the cellular level. Recently, researchers developed an improved periodontitis mouse model...
Researchers have recovered remarkably preserved microbiomes from two teeth dating back 4,000 years, found in an Irish limestone cave. Genetic analyses of these microbiomes reveal major changes in the oral microenvironment from the Bronze...
From Mesopotamian mouth worms to hippo ivory dentures, the history of tooth care is long, winding and absolutely gruesome Dentistry is as ancient as teeth, because teeth are terrible , just an atrocious invention. A 14,000-year-old...
A team of researchers has discovered a noninvasive, low-cost test to detect oral cancer, monitor precancerous lesions and determine when a biopsy is warranted.
An inexpensive, cavity-fighting liquid called silver diamine fluoride (SDF) works as well as dental sealants to keep tooth decay at bay in a school cavity prevention and treatment program, according to a new study. The study, which...
Researchers found that the oral bacterium Streptococcus gordonii activates another bacterial species, Fusobacterium nucleatum, to produce large quantities of methyl mercaptan, a compound responsible for bad breath. Disrupting this...
Researchers have found that gargling with an antiseptic mouthwash can reduce so-called 'bad' bacteria in the mouths of patients with type 2 diabetes. Notably, this reduction in bacteria was accompanied by improved blood-sugar control in...
Rickets ran rife in children following the Industrial Revolution, but new research has found factory work and polluted cities aren't entirely to blame for the period's vitamin D deficiencies.
My friend Jan Mokrzycki, who has died aged 91, was the innovative president of the Federation of Poles in Great Britain for 10 years. He campaigned for the country’s entry into the EU and for the rights of Polish people in the UK once...
What did people eat on the west coast of Scandinavia 10,000 years ago? A new study of the DNA in a chewing gum shows that deer, trout and hazelnuts were on the diet. It also shows that one of the individuals had severe problems with her...
Researchers have found an inexpensive tool that may help reduce rates of pneumonia for hospitalized patients -- and it comes with bristles on one end. A new study examined whether daily toothbrushing among hospitalized patients is...
Widespread caries and toothache -- but also some dental work and filing of front teeth. Viking Age teeth from Varnhem bear witness to surprisingly advanced dentistry.
A study may shed light on tooth enamel development disruption by revealing a new children's autoimmune disorder that hinders proper tooth enamel development. The disorder is common in people with a rare genetic syndrome and in children...
Scientists are testing a novel technology to treat endodontic diseases more effectively through tissue regeneration instead of root canal therapy. Because the technology promotes formation of the type of stem cells that can differentiate...
The Second Plague Pandemic of the mid-14th century, also known as the Black Death, killed 30-60 percent of the European population and profoundly changed the course of European history. New research suggests that this plague, potentially...
Common oral infections, periodontal diseases and caries, are associated with inflammatory metabolic profiles related to an increased risk of cardiometabolic diseases, a new study by an international team of researchers suggests. Oral...
My father, Arnold Franks, who has died aged 93, was a dentist by occupation, but a quietly revolutionary one. He helped reshape dental theory and practice, while as a clinician devoted himself to some of the most marginalised groups. As...
Americans who have a tooth pulled or another painful dental procedure in the United States today are far less likely to get opioid painkillers than they were just a few years ago, a new study shows. But the COVID-19 pandemic seems to...
Dentists study prevention, detection, management and treatment of oral and dental diseases, and the maintenance of oral and dental health Continue reading...
An essential protein that acts as a gatekeeper for calcium entering cells promotes the growth of oral cancer and generates pain, according to a new study. Targeting this protein -- the ORAI1 calcium channel -- could provide a new...
Teeth could be capable of preserving antibodies for hundreds of years, allowing scientists to investigate the history of infectious human diseases, a new study has found.
Organoids have now been created from stem cells to secrete the proteins that form dental enamel, the substance that protects teeth from damage and decay. A multi-disciplinary team of scientists led this effort. This is a critical first...
As the 10th series of the ITV show finishes, viewers may have noticed the perfectly straight, white teeth of the contestants. But are there risks associated with achieving a flawless smile? In this episode from January 2023, Madeleine...
Although most people don't associate oral disease with serious health problems, increasing evidence shows that oral bacteria play a significant role in systemic diseases like colon cancer and heart disease. Now, new research shows a link...
