Dried Licorice Root Fights The Bacteria That Cause Tooth Decay And Gum Disease

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 study in ACS' Journal of Natural Products, they say that these substances could have a role in treating and preventing tooth decay and gum disease.

Dentists Could Screen 20 Million Americans For Chronic Physical Illnesses

Nearly 20 million Americans annually visit a dentist but not a general healthcare provider, according to an NYU study published in the American Journal of Public Health.

The study, conducted by a nursing-dental research team at NYU, is the first of its kind to determine the proportion of Americans who are seen annually by a dentist but not by a general healthcare provider.

This finding suggests dentists can play a crucial role as health care practitioners in the front-line defense of identifying systemic disease which would otherwise go undetected in a significant portion of the population, say the researchers.

Addition Of Mannitol Increases Effectiveness Of Dental Nerve Block Anesthesia

Allowing a patient to be comfortable and pain-free during surgical and restorative dental procedures is an essential part of the process. The most commonly used local anesthetic injection for lower teeth is the inferior alveolar nerve (IAN) block. However, failure rates ranging from 10 to 39 percent have been reported.

The current issue of the journal Anesthesia Progress presents a study testing the efficacy of adding a solution of mannitol to the anesthetic typically used in IAN blocks. Forty adult subjects participated in the study, receiving an IAN block at each of three separate appointments at least one week apart.
