A discovery of multiple toothpick grooves on teeth and signs of other manipulations by a Neanderthal of 130,000 years ago are evidence of a kind of prehistoric dentistry, according to a new study led by a University of Kansas researcher.
In early childhood caries, a severe form of tooth decay that affects more than a third of toddlers in the US, yeast often partners with bacteria to form an intractable biofilm. New research led by Hyun (Michel) Koo and Geelsu Hwang of the School of Dental Medicine at the University of Pennsylvania reveals the mechanisms and suggests a way to block the interaction and reduce plaque.
Imagine walking along a beach on a lovely day. As you turn to continue along the coast path feeling calm and relaxed you suddenly hear your dentist say 'Fine, all done, you can take the headset off now'. For patients at one dental practice in Devon, England, such Virtual Reality encounters are resulting in demonstrably better experiences in the dentist's chair.
According to a recent study, a common periodontal pathogen may delay concepcion in young women.
Researchers at OHSU in Portland, Oregon, have developed a process by which they can engineer new blood vessels in teeth, creating better long-term outcomes for root canal patients and clinicians.
Aesthetic treatments are always widely sought by dental patients, especially dental whitening, in order to get whiter smiles. The big demand for this type of procedure raises the concern in the dental research community that this type of treatment has the potential to make dental alterations that cause damage to the dental structure and if there are suitable components that can be added to dental bleaching agents to reduce such effects.
Calcium carbonate combined with sea urchin proteins form tiny stacks of 'bricks' that creates a structure which provides a tough, exoskeleton defense for the sea creature. NYU Dentistry research studying the protein may enable the development of tunable fracture resistant materials that one day will find its use in developing lightweight 'armor' and 'sturdier' dental composites.
Likely the first bone tumor from an ancient skeleton in Central America is reported by Smithsonian archaeologists and colleagues. The starburst-shaped tumor is in the upper right arm of the skeleton of an adolescent buried in about 1300 AD in a trash heap at a site in western Panama called Cerro Brujo or Witch Hill. The reason for what appears to be a ritual burial in this abandoned pre-Colombian settlement is unknown.
Recreational use of cannabis -- including marijuana, hashish, and hash oil -- increases the risk of gum disease, says a study by Columbia University dental researchers.
In the first study examining dental records in the Rochester Epidemiology Project, results show that dentists and oral surgeons are in good compliance with guidelines issued by the American Heart Association (AHA) in 2007, describing prophylactic antibiotic use prior to invasive dental procedures.
