Researchers analyze impact of chemical BPA in dental sealants used in children

Researchers have found that bisphenol A (BPA) released from some plastic resins used in pediatric dentistry is detectable in the saliva after placement in children’s mouths.

What can a New Zealand reptile tell us about false teeth?

Using a moving 3-D computer model based on the skull and teeth of a New Zealand reptile called tuatara, researchers have revealed how damage to dental implants and jaw joints may be prevented by sophisticated interplay between our jaws, muscles and brain.

‘Jailbreak’ bacteria can trigger heart disease

Plaque-causing bacteria can jailbreak from the mouth into the bloodstream and increase your risk of heart attack, according to new research.

Fluoride in water prevents adult tooth loss, study suggests

Children drinking water with added fluoride helps dental health in adulthood decades later, a new study finds.

Gum inflammation linked to Alzheimer’s disease

Dental researchers have found the first long-term evidence that periodontal disease may increase the risk of cognitive dysfunction associated with Alzheimer’s disease in healthy individuals as well as in those who already are cognitively impaired. The study offers fresh evidence that gum inflammation may contribute to brain inflammation, neurodegeneration, and Alzheimer’s disease.

Pilot safety protocol could help dentists reduce errors

Pilots and dentists have more in common than one might think: Both jobs are highly technical and require teamwork. Both are subject to human error where small, individual mistakes may lead to catastrophe if not addressed early.

Tongue piercing may cause gapped teeth; Could cost thousands of dollars in orthodontic repairs

Mark this one down as a parental nightmare. First, your child gets her tongue pierced. Then, as if you needed something else, she starts “playing” with the tiny barbell-shaped stud, pushing it against her upper front teeth. And before you know it, she forces a gap between those teeth — a fraction-of-an-inch gap that may cost thousands of dollars in orthodontic bills to straighten.

Novel cause for genetic tooth decay

New research implicates a novel peptide in impaired dentin mineralization in rickets. Rickets, the softening of bones in children, is often caused by vitamin D deficiency due to severe malnutrition. Rickets is one of the most frequent childhood diseases in developing countries and is associated with severe bone deformities, including dental ailments due to impaired dentin mineralization.

Gene may hold key to reducing spread of oral cancers

The spread of cancer cells in the tongue may be reduced if a gene that regulates cancer cell migration can be controlled, according to new research.

Quitting smoking may minimize harmful bacteria and replenish healthy bacteria

Patients with chronic gum disease who quit smoking in addition to undergoing nonsurgical therapy not only demonstrated a lower abundance of harmful oral pathogens, but also an increase in health-associated bacteria.
