The Wall Street Journal (2/8, Johannes, Subscription Publication) reviewed a new toothpaste that aims to improve oral hygiene by binding to plaque and showing it as green, revealing areas a person missed while brushing. The article stated that researchers at the University of Illinois at Chicago conducted a short-term study of Plaque HD, finding plaque was reduced by 51.3% after people brushed with the toothpaste for up to 10 days. American Dental Association spokeswoman Dr. Mary Hayes has not tried the toothpaste, but said it could serve as a consistent reminder to patients. Dr. Hayes added that areas between the teeth and at the gumline are common areas patients miss.
