It takes both teeth and jaws to make a pretty smile, but the evolutionary origins of these parts of our anatomy have only just been discovered, thanks to a particle accelerator and a long dead fish.

A new prototype for medicated chewing gum has been developed for motion sickness that may offer many advantages over conventional oral solid dosage forms. About 33 percent of people are susceptible to motion sickness in mild circumstances and 66 percent are affected in more severe conditions.

As we enter the sweet season, parents are worried kids might indulge their way to obesity by gobbling up too many Halloween candy. But having a little fun with candy once a year will not lead to childhood obesity, says a pediatrics expert.

The ideal sedative for oral surgery should make the patient comfortable during the surgery and should wear off quickly enough that the patient can leave the dental chair soon after the procedure. Finding the best plan of anesthetic treatment is essential to the success of dental procedures such as the extraction of wisdom teeth.

In an effort to identify the thousands of John/Jane Doe cold cases in the United States, scientists have found a multidisciplinary approach to identifying the remains of missing persons. Using “bomb pulse” radiocarbon analysis, combined with recently developed anthropological analysis and forensic DNA techniques, the researchers were able to identify the remains of a missing child 41 years after the discovery of the body.

There are various types of toothpaste available on the market. They come as pastes and gels, there are some that guard against tooth decay or protect teeth from acid attack, others that are designed for sensitive teeth. But which toothpastes clean well? Which preserve the tooth enamel? A new evaluation method sheds light on the subject.

Can you bite into an apple? If so, you are more likely to maintain mental abilities, according to new research.

Researchers may have uncovered new evidence of ancient dentistry in the form of a 6,500-year-old human jaw bone with a tooth showing traces of beeswax filling.

Pancreatic cancer is highly lethal and difficult to detect early. In a new study, researchers report that people who had high levels of antibodies for an infectious oral bacterium turned out to have double the risk for developing the cancer. High antibody levels for harmless oral bacteria, meanwhile, predicted a reduced pancreatic cancer risk.

The cellular cause of birth defects like cleft palates, missing teeth and problems with fingers and toes has been a tricky puzzle for scientists. Now biochemists studied an ion channel that regulates the electrical charge of a cell and found that blocking this channel disrupts the work of a protein that is supposed to carry marching orders to the nucleus. This newly discovered mechanism may be what some birth defect disorders have in common, opening the door for the pursuit of a preventative treatment.
