Scientists are reporting identification of two substances in licorice — used extensively in Chinese traditional medicine — that kill the major bacteria responsible for tooth decay and gum disease, the leading causes of tooth loss in children and adults. In a new study, they say that these substances could have a role in treating and preventing tooth decay and gum disease.
Laboratory-grown gingival cells treated with vitamin D boosted their production of an endogenous antibiotic, and killed more bacteria than untreated cells, according to a new study. The research suggests that vitamin D can help protect the gums from bacterial infections that lead to gingivitis and periodontitis. Periodontitis affects up to 50 percent of the US population, is a major cause of tooth loss, and can also contribute to heart disease. Most Americans are deficient in vitamin D.
African-Americans receive poorer dental care than white Americans, even when they have some dental insurance coverage. To better understand why this is so, researchers surveyed African-American adults with recent oral health symptoms, including toothaches and gum disease. Their findings provide insights into why disparities persist even among those with dental insurance and suggest strategies to removing barriers to dental care.
