Terror Attack Survivors More Prone to Headaches

Researchers have shown that survivors of a terror attack have an increased risk of frequent migraine and tension headaches developing after the attack. Therefore there are potential physical effects of violent incidents in addition to the better known psychological effects. The researchers studied the responses teenage survivors of the largest mass killing in Norway that occurred in 2011. In the attack, a lone gunman opened fire at a youth summer camp on Utøya Island, killing 69 people and severely wounding 33. All survivors experienced terror, some lost friends, and some risked drowning as they tried to escape the island. The study shows that a single highly stressful event such as a terror attack may lead to ongoing suffering with frequent migraines and other headaches. All 358 teenage survivors of the incident were invited to participate in the study. A total of 213 … Read more

Nanodiamonds to Help With Root Canal Recovery

Researchers at UCLA found in a clinical trial that nanodiamonds protected disinfected root canals after the nerve and pulp were removed. This result may help people who undergo root canals as it could help prevent infection after treatment. Specifically combining nanodiamonds with gutta percha, a material used to fill disinfected root canals, may enhance the gutta percha’s protective properties. Nanodiamonds are tiny particles made of carbon and are very very small. Nanodiamonds have previously been explored to deliver drugs and serve as imaging agents. Protecting disinfected root canals is a delicate process. Dentists use gutta percha to block bacteria from infiltrating the tooth, but it can break during the procedure or create pockets of space for bacteria to infiltrate. The researchers tested nanodiamond-embedded gutta percha (NDGP) in three people who undergoing root canal procedures. These tests demonstrated the implanted material NDGP … Read more

Having diabetes can lead to periodontitis

Those with diabetes may end up with periodontitis, a gum infection which causes tooth loss. University of Pennsylvania researchers has found diabetes triggers changes in oral microbiome which increases inflammation and increases the risk of bone loss. Prior studies before this work did not show any evidence that diabetes affects the oral microbiome. In addition over four years ago, the European Federation of Periodontology and the American Academy of Periodontology issued a report describing how there is evidence that diabetes is linked to changes in the oral microbiome. The University of Pennsylvania researchers collaborated with Peking University, the University of São Paulo, Sichuan University, the Federal University of Minas Gerais, and the University of Capinas. The authors consulted with the Penn Center for Musculoskeletal Diseases. The researchers first explored the oral microbiome of diabetic mice compared to healthy mice. It was found … Read more

Microbes to Modify Nitrates in Migraine Headache Sufferers

Researchers at the University of California San Diego have found that the mouths of those who suffer from migraine headaches have significantly more microbes with the ability to modify nitrates than people who do not have headaches. Many of the millions of Americans who suffer from migraines report an association between consuming foods with nitrates and the intensity of their headaches. The researchers were interested in exploring the idea that foods can trigger migraines and in particular exploring the microbiome connection with migraines. In addition, four in five cardiac patients who take nitrate-containing drugs often report headaches as a side effect. Nitrates are found in foods including processed meats and green leafy vegetables. Nitrite reducing bacteria found in the mouth can reduce the nitrates to nitrites. These nitrites can then be converted to nitric oxide when circulating in blood. Nitric oxide … Read more

Dental X-rays Show Vitamin D Deficiency

McMaster anthropologists have found that human teeth hold important information about Vitamin D deficiency which can be identified by a dental X-ray. The researchers had previously discovered that human teeth hold a detailed and permanent record of Vitamin D deficiency. The teeth show microscopic deformities in dentin. This is preserved by enamel which protect teeth from breaking down. Vitamin D deficiency often occurs when a human does not get enough exposure to sunlight. This work is useful for examining the teeth of people who lived years ago to see if they were ever deprived of sunlight and had Vitamin D deficiency. An issue when looking for teeth deformities currently is that that a tooth must be cut open and there are limited teeth the researchers had access to. To avoid wasting specimens, the researchers tried to find a way to … Read more
