Hypochlorous Acid (HOCl) mouth rinse preserves the commensal (good) oral bacteria. It also is surprisingly efficacious at killing oral pathogens-even the really bad guys.1-5 What makes HOCl a super-hero is its compatibility with our physiological needs.11,13 Our fragile, essential oral microbiome can be affected by many things including oral products, antibiotics, diet, health which can indirectly contribute … Read more

UB Study Finds Some Oral Bacteria Linked with Hypertension in Older Women

Some oral bacteria were associated with the development of hypertension, also known as high blood pressure, in postmenopausal women, according to new research led by and published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association. High blood pressure is typically defined by two measurements: systolic … Read more

New Study Demonstrates How Oral Bacteria Can Amplify Gut Inflammation

Building on the growing link between poor oral health and gastrointestinal disease, new research from the University of Michigan has homed in on the possible mechanisms by which periodontitis can exacerbate the gut inflammation seen in patients with inflammatory bowel disease (IBD). It is becoming increasingly clear the trillions of bacteria living inside our bodies … Read more

Presence of Oral Bacteria in Cerebral Emboli of Stroke Patients

Researchers at Tampere University have shown for the first time that the cerebral emboli of stroke patients contain DNA from oral pathogens. The research article has been published in the Journal of American Heart Association. The researchers analysed thrombus aspirates, which neurointerventional radiologists removed from 75 stroke patients as part of emergency treatment. The samples were … Read more

Periodontal Disease Bacteria Linked to Alzheimer’s Disease

A recent study has periodontists, experts in the treatment, diagnosis, and prevention of periodontal disease, encouraging patients to maintain gum health in an effort to reduce their Alzheimer’s disease risk. The study, published in the journal Science Advances, uncovered a potential link between P. gingivalis, the bacteria associated with periodontal disease (commonly known as gum … Read more

Periodontal Disease Bacteria May Kick-Start Alzheimer’s

Long-term exposure to periodontal disease bacteria causes inflammation and degeneration of brain neurons in mice that is similar to the effects of Alzheimer’s disease in humans, according to a new study from researchers at the University of Illinois at Chicago. The findings, which are published in PLOS ONE, suggest that periodontal disease, a common but preventable … Read more

Antibiotics Destroy Immune Cells and Worsen Oral Infection, Says Study

New research shows that the body’s own microbes are effective in maintaining immune cells and killing certain oral infections. A team of Case Western Reserve University researchers found that antibiotics actually kill the “good” bacteria keeping infection and inflammation at bay. Scientists have long known that overuse of antibiotics can do more harm than good. … Read more

Differences in Mouths of Youth Born With HIV May Increase Risk of Dental Decay

A team of scientists from The Forsyth Institute, a global leader in oral health research, in collaboration with the NIH-funded Pediatric HIV/AIDS Cohort Study (PHACS), has published the results of a new study indicating that differences in the mouth bacteria of youth born with HIV may increase their risk of cavities. The researchers found that … Read more

Researchers Develop Film to Prevent Bacteria on Dental Retainers, Aligners

Clear, plastic aligners have been growing in popularity as alternatives to bulky, metal braces. And once the teeth are straightened, patients graduate to plastic retainers to maintain the perfect smile. But these appliances can become contaminated, so one group is now reporting in ACS Applied Materials & Interfaces that they have developed a film to prevent bacteria … Read more

Oral, Gastric Bacteria May Help Pinpoint Stomach Cancer

Microbial markers could prove useful for diagnosing stomach cancer and its precursors earlier and less invasively, according to a study that identified stomach and oral bacteria that may be involved in gastric tumorigenesis. There were negative changes in microbial composition and interactions across various steps in the path to gastric carcinogenesis (GC), reported Jun Yu, … Read more

Cellular Messengers Linked to Growth of Oral Bacteria

A new UCLA-led study provides clear evidence that cellular messengers in saliva may be able to regulate the growth of oral bacteria responsible for diseases, such as periodontitis and meningitis. The study’s findings, which suggest that a body’s cellular messengers play an important role in managing the amount of good and bad bacteria in the … Read more

Alcoholic Drinks Linked to Harmful Oral Bacteria

When compared with nondrinkers, men and women who had one or more alcoholic drinks per day had an overabundance of oral bacteria linked to gum disease, some cancers, and heart disease. By contrast, drinkers had fewer bacteria known to check the growth of other, harmful germs. These are the main findings of a study published … Read more

Bacteria in Mouth Linked to Reasoning Behind Migraines

People who suffer from migraines have long complained that certain foods trigger the severe headaches. New research suggests the culprit might be the amount of bacteria in the mouth. Researchers found that the mouths of people who suffer from migraines harboured significantly more of the microbes that break down nitrates found in certain foods. These bacteria play … Read more
