Peri-implantitis, a condition where tissue and bone around dental implants becomes infected, besets roughly one-quarter of dental implant patients, and currently there’s no reliable way to assess how patients will respond to treatment of this condition.
Maintenance of good oral health is more important than use of antibiotics in dental procedures for some heart patients to prevent a heart infection caused by bacteria around the teeth, according to a new American Heart Association (AHA) scientific statement published today in the Association’s flagship journal, Circulation.
Older adults with more harmful than healthy bacteria in their gums are more likely to have evidence for amyloid beta – a key biomarker for Alzheimer’s disease – in their cerebrospinal fluid (CSF), according to new research from the New York University College of Dentistry and Weill Cornell Medicine. However, this imbalance in oral bacteria was not associated with another Alzheimer’s biomarker called tau.
David Clapham, vice president and chief scientific officer of the Howard Hughes Medical Institute (HHMI) in the United States and an international team of scientists have figured out how teeth sense the cold and pinpointed the molecular and cellular factors involved. In both mice and humans, tooth cells called odontoblasts contain cold-sensitive proteins that detect temperature drops, the team reports in the journal Science Advances.
