Gum disease, especially the kind that is irreversible and causes tooth loss, may be associated with mild cognitive impairment and dementia 20 years later, according to a study published in the July 29, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology.
A new, 3D-printed technology that was inspired by Lego block toys is designed to help heal broken bones, and could one day even lead to lab-made organs for human transplant.
KAIST researchers used atomic force microscopy to quantitatively evaluate how acidic and sugary drinks affect human tooth enamel at the nanoscale level. This novel approach is useful for measuring mechanical and morphological changes that occur over time during enamel erosion induced by beverages.
In research first published as a pre-print in 2018, and now formally in the journal Cell Reports, scientists describe their findings that Saccharibacteria within a mammalian host are more diverse than ever anticipated. The researchers also discovered that certain members of the bacteria are found in the oral cavity of humans, the guts of other mammals, and in groundwater.
Virginia Tech researchers have discovered that one of these common bacteria can leave the mouth and potentially cause existing cancer cells in other parts of the body to spread.
Recent studies indicate HIV infection heightens the risk of dental cavities - but a Rutgers researcher has found evidence that the risk of cavities comes not from HIV itself but from a weakened immune system, which could be caused by other diseases.
Medicated chewing gum has been recognised as a new advanced drug delivery method but currently there is no gold standard for testing drug release from chewing gum in vitro. New research by the University of Bristol has shown a chewing robot with built-in humanoid jaws could provide opportunities for pharmaceutical companies to develop medicated chewing gum.
A collaboration between the University of Toronto's Faculty of Dentistry and the National Jewish Health in Denver -- the top-ranked respiratory research hospital in the US -- has yielded a new drug discovery that could be useful to combat inflammation of all varieties and shows promise in fighting acute respiratory illnesses such as COVID-19.
A small pilot study provides an early glimpse of how some veterans struggling with PTSD may benefit from one simple, inexpensive treatment involving nitrous oxide, commonly known as laughing gas.
A new study published in the Journal of Dental Research demonstrates that testing of oropharyngeal secretions may reduce the number of false negative results from nasal swab testing of patients who have seemingly recovered from the disease.
