Caries seems to run in families, and some ethnic groups appear to suffer more from it than others. The same goes for periodontal disease. So along with questions about your patients' drug use and brushing habits, should you ask how many teeth their parents have? Not according to official guidelines for assessing patients' caries and periodontal disease risk factors.

Breakthrough scientific research has strongly suggested there could be a link between having a low number of teeth and poor memory. The study, specifically related to memory decline, examined the participants from a series of cognitive assessments and their ability to recall words. The results showed that people with fewer teeth scored lower than those with more teeth in the first examination and declined far quicker after further testing in later years.More

However, many proprietary mouthwashes including my favorite brand contain alcohol (ethanol). Numerous research reports and newspaper articles suggest a possible link between their long-term use and oral cancer.More

Candy-like tobacco products: Poisoning is not the only risk
U.S. News & World Report
Tobacco products that look and taste like candy, -- and have poisoned thousands of children who mistake them for sweet treats -- are just the latest in a long line of tobacco goods that appeal to children. The threat they pose to children is not only poisoning but also an increased risk of addiction. Smokeless tobacco products poisoned 1,768 children ages 6 and younger between 2006 and 2008, researchers at the Harvard School of Public Health reported this month in Pediatrics.More

Round Town News
Excellent oral hygiene could prevent heart attacks by stopping dangerous bacteria entering the bloodstream, a British study shows. The sheer number of bacteria that can live in an unhealthy mouth -- more than 700 strains -- increases the risk of heart disease, regardless of how fit a person is.
