Periodontitis, a common inflammatory disease in which gum tissue separates from teeth, leads to accumulation of bacteria and potential bone and tooth loss. In a new study, researchers found that dietary intake of polyunsaturated fatty acids like fish oil, known to have anti-inflammatory properties, shows promise for the effective treatment and prevention of periodontitis.
Young children who consume substantial amounts of fluoride through infant formula and other beverages mixed with fluoridated water or by swallowing fluoride toothpaste have an increased chance of developing mild enamel fluorosis, according to new research. However, experts say, children can continue using fluoridated water and fluoride toothpaste because fluoride has been proven to prevent tooth decay, and mild fluorosis does not negatively affect dental health or quality of life.
Scientists are using the technique of Raman spectroscopy to study two common dental plaque bacteria, Streptococcus sanguis and mutans. The relative balance of the two may be an indicator of a patient’s oral health and risk for tooth decay — Streptococcus sanguis is associated with “healthy” plaque, while mutans is associated with tooth decay.
