A recent study from King's College London and Cambridge University highlighted that people may experience multiple subtle changes before being diagnosed with a brain tumor.
Periodontitis affects nearly half of Americans ages 30 and older, and in its advanced stages, it could lead to early tooth loss or worse. UCLA researchers have created a new class of membranes that have shown to regenerate tissue and bone. Findings could lead to a viable solution for periodontitis and wound healing.
According to the US Centers for Disease Control and Prevention, about half of all Americans will have periodontal disease at some point in their lives. Characterized by inflamed gums and bone loss around teeth, the condition can cause bad breath, toothache, tender gums and, in severe cases, tooth loss. Now, in ACS Nano, researchers report development of a membrane that helps periodontal tissue regenerate when implanted into the gums of rats.
Gum disease (gingivitis) that goes untreated can become periodontitis, causing loss in the bone that supports your teeth. Periodontitis is the main cause of tooth loss in adults. Periodontitis is also a risk factor for developing dementia. Recently, researchers in South Korea studied the connection between chronic periodontitis and dementia. They published their findings in the Journal of the American Geriatrics Society.
The presence of oral bacteria in so-called cystic pancreatic tumours is associated with the severity of the tumour, a study by researchers at Karolinska Institutet in Sweden published in the journal Gut reports. It is hoped that the results can help to improve diagnosis and treatment of pancreatic cancer.
Periodical dust loads on foods places dietary-physiological stress on the digestive system in chimpanzees. This is the conclusion reached by an international research team headed by scientists from the Max Planck Institute for Evolutionary Anthropology (MPI-EVA) in Leipzig. Their study implicates that extrinsic abrasive particles carried by dust-laden winds affect tooth wear and evolutionary fitness.
In a Community Dentistry & Oral Epidemiology study, poor cognitive function in older adults was associated with poorer oral health and higher risk of tooth loss in later life.
A large breakthrough has been made in the genetic understanding of mouth ulcers which could provide potential for a new drug to prevent or heal the painful lesions. Mouth ulcers affect up to 25 percent of young adults and a higher proportion of children. Previous research has shown that mouth ulcers are partially heritable, but until now there has been little evidence linking specific genes or genomic regions to mouth ulcers.
A compound used to make car bumpers strong and protect wood decks could prevent return visits to the dentist's office. A team of researchers with the OHSU School of Dentistry in Portland, Oregon, have created a filling material that's two times more resistant to breakage than standard fillings. The team also has developed an adhesive that's 30 percent stronger after six months in use than adhesives that are currently used to keep fillings in place.
Researchers have determined how a type of bacteria commonly found in the mouth accelerates the growth of colon cancer.
