Big Burgers Might Give Asians TMJ

SINGAPORE—An American-trained dentist who runs a clinic in Singapore says small-mouthed Asians can injure their jaws with large Western burgers.

In a Voice of America report, prosthodontist Ansgar Cheng said dentists in Asia are seeing more jaw disorders among its growing middle class because they are eating big-sized Western-style fast food.

Canada Declares BPA Toxic, Sets Stage for More Bans

Canada has declared bisphenol A a toxic chemical, prompting calls for far-reaching curbs on the industrial chemical that is used in everything from the linings of aluminum cans to coatings on electronic till receipts.

Canada added the compound, known as BPA, to a list of substances deemed potentially harmful to health or the environment in a notice published in the Canada Gazette on Wednesday.

That makes it easier for Ottawa to regulate the use of the chemical, perhaps by limiting how much BPA can be released into air or water or perhaps with outright bans on its use in specific food containers.

Good Nutrition Leads to a Healthy Mouth and Body

HARRISBURG, Pa.—Good nutrition and healthy eating habits are essential to maintaining optimal oral and overall health. With Halloween just around the corner, the Pennsylvania Dental Association (PDA) encourages parents to be mindful of the amount of candy their children are consuming, and to use this holiday as an opportunity to remind them about the importance of taking care of their teeth and gums.

The food and beverage choices you make have a direct effect on the health of your entire body. Each time a sugary snack or beverage is consumed, the sugar, along with the bacteria in your mouth, bathe your teeth in harmful acids that attack your teeth for at least 20 minutes. Each bite or sip brings on another acid attack. After repeat attacks, teeth are susceptible to tooth decay.

OHSU School of Dentistry Examines Antimicrobial Drug Interactions

PORTLAND, Ore.—Researchers at the Oregon Health & Science University School of Dentistry have found that a light-detecting biosensor system can quickly and effectively determine whether antibacterial treatments are working in patients with periodontitis, a serious gum infection that can cause tooth loss and is associated with an increased risk of heart attack or stroke and other serious health problems.

The OHSU team also found that the anesthetics lidocaine and prilocaine, and the antiseptic chlorhexidine do not interfere with the antibiotic minocycline hydrochloride when it is used to treat periodontal disease, and that the drugs can actually complement the antimicrobial activity of such treatment.

New Motivation for Children and iPhone Fans to Brush Their Teeth

KREFELD, Germany—To many children, brushing their teeth is just a cumbersome chore, which leads to the same old frustrating battle in the bathroom between parents and their offspring. But now Krefeld-based psychiatrist Dr Einhardt Illing has developed an iPhone app that provides guidance and motivation for brushing—and a little bit of fun to boot.

The new tooth brushing motivator “Motivetrix” guides the user through brushing using color sequences and motivates them with imaginary painting. The iPhone screen shows a diagram of the human set of teeth and displays the individual tooth areas in different colors at intervals. The user follows the color sequence with his or her toothbrush. Brushing is complete when the whole set of teeth is colored in.

The imaginary coloring turns brushing into a game. The 2- to 3-minute brushing time specified by dentists is over in a flash.
