In a study titled "MicroRNA Modulation in Obesity and Periodontitis," lead author Romina Perri, University of North Carolina School of Dentistry, Oral Health Institute, conducted a pilot investigation to determine whether obesity or periodontal disease modified microRNA expression and whether there was any potential interaction between obesity and periodontitis that could involve microRNA modulation. This study is published in the Journal of Dental Research, the official publication of the International and American Associations for Dental Research. In this investigation, total RNA was extracted from gingival biopsy samples collected from 20 patients in 4 groups.More

Dental benefits of sugar-free foods debated
Nursing Times
"Sugar-free gum, sweets and soft drinks, marketed as healthy alternatives to sugary products, can damage teeth, cause gastric problems and are unlikely to promote weight loss," The Guardian has reported. The news is based on a review of the oral health effects of sugar-free products, and in particular, a group of sweeteners called polyols that are often added to sweets, drinks and chewing gum. It is already well known that dental cavities can be formed when bacteria convert sugars in food into acid, which breaks down tooth enamel. However, in this new study, researchers looked for evidence on whether foods containing certain sugar substitutes were beneficial for dental health.More

A diet supplemented with a combination of fruit and vegetable juice powder concentrates may help combat chronic periodontal disease when combined with conventional dental therapy, according to a new study in the Journal of Clinical Periodontology. The results of a preliminary randomized controlled study conducted at the University of Birmingham showed that taking a daily dose of capsules containing concentrated phytonutrients improved clinical outcomes for patients with chronic periodontitis in the two months following nonsurgical periodontal therapy, with additional beneficial changes recorded at five and eight months after therapy. The study is the first of its kind to report the impact of giving periodontitis patients such a supplement during standard mechanical therapy, according to the study authors.More

Among the myriad health problems faced by many Native Americans is poor oral health, a study has found. Overall, 90 percent of residents of the Pine Ridge Indian Reservation in South Dakota had at least one decayed tooth, according to Terry Batliner, DDS, and colleagues from the University of Colorado in Denver. Among 135 adults examined, 97 percent had one or more decayed teeth, as did 84 percent of 157 children, the researchers noted in a report from the W.K. Kellogg Foundation presented at the National Congress of American Indians in Portland, Ore. Little is known about the contemporary oral health of Native Americans, with the last report on their dental health needs having been published more than a decade ago.More

Blisstree
With Halloween comes fear, mainly of cavities and weight gain. But if you're not careful, you could end up with a real horror show on your hands: gum disease. It's something that is surprisingly easy to develop, even if you're a devoted gym rat and eat a totally clean, low-sugar diet. E, a successful executive in Toronto who prides herself on her pristine physical health, told us that she visited her dentist only to get shocking feedback from her hygienist: that while she appeared to take great care of her health, her oral health was in shambles, and would require serious attention to get back on track. She's been able to repair the damage done from forgetting to floss, but often, the outcome isn't so pretty.More
