https://medicalxpress.com/dentistry-news/ en-us Latest medical news and research in Dentistry New research from Trinity College Dublin shows no link between exposure to community water fluoridation (CWF) and later-life cognitive function in older Irish adults. The research also found no evidence that exposure in early childhood had any impact either. https://medicalxpress.com/news/2026-11-link-fluoridation-cognitive-decline-older.html Mon, 09 Nov 2026 16:40:05 EST news713453581 A lot of time and effort goes into toothbrush technology, whether changing bristle angles or tweaking and improving electric models. No matter the developments, they all essentially still do the same thing to a greater or lesser degree, which is using a mechanical scrubbing motion to clean teeth. https://medicalxpress.com/news/2026-11-toothbrush-generates-electricity-bacteria.html Thu, 05 Nov 2026 10:20:17 EST news713093822 Rare variants in a gene involved in early development have been linked to a range of dental differences in people, including missing teeth, unusual tooth shapes and teeth present at birth. By studying changes in the same gene in mice and chickens, researchers have also uncovered clues to how differences in tooth number and shape evolved across species, including how birds may have lost their teeth. https://medicalxpress.com/news/2026-10-rare-gene-variants-linked-dental.html Mon, 26 Oct 2026 17:20:14 EDT news712251093 A single tooth can contain valuable clues to a person's identity, even when remains are severely decomposed or reduced to bones, according to a study by researchers at the Institute of Science Tokyo. By applying multiple forensic methods to different tissues within a single tooth, the researchers obtained six types of information about the deceased. This integrated approach could provide complementary evidence to help identify unknown human remains when conventional methods are difficult to apply. https://medicalxpress.com/news/2026-10-tooth-clues-deceased-persons.html Wed, 21 Oct 2026 18:00:07 EDT news711818103 Researchers at the University of Missouri have uncovered a promising way to protect saliva-producing glands from radiation damage that can make it difficult to eat, swallow, sleep and maintain oral hygiene. https://medicalxpress.com/news/2026-10-drug-salivary-glands-treatment.html Wed, 21 Oct 2026 11:40:02 EDT news711795335 Boil them, mash them, simmer them in a sauce. Whether they're sweetening a salad, garnishing a cocktail or brightening up home decor, cranberries are an iconic ingredient in holiday festivities. UIC College of Dentistry researcher Christine Wu found another reason to add these tart treats to your grocery cart: oral health. https://medicalxpress.com/news/2026-10-cranberry-juice-boon-oral-hygiene.html Tue, 20 Oct 2026 18:10:01 EDT news711736201 A research team from the Faculty of Dentistry at The University of Hong Kong (HKU), working in collaboration with Su Ryon Shin's group at Brigham and Women's Hospital, Harvard Medical School, has advanced and preclinically validated a shape-adaptive hydrogel designed for challenging clinical trauma scenarios involving severe bleeding, irregular bone defects and comminuted fractures. https://medicalxpress.com/news/2026-10-moldable-gel-bone-preclinical.html Thu, 15 Oct 2026 19:20:01 EDT news711296221 Whether you're a quick or slow thinker depends on several factors, such as the efficiency of the brain's wiring and the amount of gray matter in specific control centers. But there may be another, rather surprising influence, and that's the bacteria in your mouth. Scientists have found an association between the mix of microbes on your tongue and how well the brain performs cognitive tasks as we age. https://medicalxpress.com/news/2026-10-bacteria-tongue-linked-brainpower.html Mon, 12 Oct 2026 12:40:02 EDT news711023251 Scientists have shown that a naturally occurring virus can dismantle complex bacterial communities responsible for severe gum disease, offering a potential alternative to traditional antibiotics. In the first study to demonstrate this effect, La Trobe University researchers found that the FNU1 virus selectively attacked Fusobacterium polymorphum, a bacterial species that helps other disease-causing bacteria stick together and thrive. https://medicalxpress.com/news/2026-09-scientists-gum-disease-bacteriophage-virus.html Mon, 14 Sep 2026 15:20:03 EDT news708611454 A combination of omega-3 and low-dose acetylsalicylic acid (ASA) produced results comparable to antibiotics in treating severe periodontitis. This conclusion is based on a study conducted by researchers affiliated with Albert Einstein Israelite Hospital, Guarulhos University (UNG), the University of Taubaté (UNITAU), and the Ribeirão Preto School of Dentistry at USP (FORP-USP) in Brazil, as well as Harvard University in the United States. https://medicalxpress.com/news/2026-08-omega-dose-aspirin-antibiotic-results.html Fri, 07 Aug 2026 12:00:05 EDT news705319681 Researchers at Nagoya University in Japan have created an innovative treatment for periodontitis that targets and eliminates harmful bacteria while preserving beneficial oral microbes essential for health. The findings were published in the Journal of Translational Medicine. https://medicalxpress.com/news/2026-08-therapy-gum-disease-bacterium-beneficial.html Tue, 04 Aug 2026 14:40:01 EDT news705066901 Exposure to secondhand cigarette smoke during the first days of life can cause changes in tooth enamel mineralization without causing visible changes to the teeth. This was demonstrated in an animal model study conducted by researchers at the Ribeirão Preto School of Dentistry at the University of São Paulo (FORP-USP) in Brazil. The results were published in May in the scientific journal Calcified Tissue International. https://medicalxpress.com/news/2026-08-rat-early-secondhand-exposure-tooth.html Sat, 01 Aug 2026 07:00:03 EDT news704769247 A major study has ruled out inflammation as the cause of a developmental condition affecting children's teeth while also revealing how common the condition is. https://medicalxpress.com/news/2026-07-root-common-dental-defect-children.html Thu, 30 Jul 2026 10:20:03 EDT news704622291 Every year, untreated tooth decay sends thousands of young U.S. children to emergency departments for dental problems doctors can't treat.
