Dental implants used to replace single teeth continue to function well after several decades, according to a new study. After nearly forty years, all examined implants were still in place and fully functional.
Researchers have shown that innate immune training, also known as trained immunity (TRIM), leads to aggravated bone loss in experimental models of periodontitis and inflammatory arthritis.
It's common knowledge that sugar causes cavities, but new research provides evidence that -- depending on your genetic makeup -- starches could also be a contributing factor.
Bill pushed through by Republicans awaits governor’s signature to outlaw addition of mineral to water Utah is poised to become the first state to ban fluoride from its water systems with a bill now before its Republican governor, Spencer...
Sweden's Viking Age population appears to have suffered from severe oral and maxillofacial disease, sinus and ear infections, osteoarthritis, and much more. This is shown in a study in which Viking skulls were examined using modern X-ray...
New research could transform how broken bones are treated, with the development of a special zinc-based dissolvable material that could replace the metal plates and screws typically used to hold fractured bones together.
People who regularly floss their teeth (one or more times per week) may lower their risk of stroke caused by a blood clot traveling from the heart and a stroke associated with an irregular heartbeat such as atrial fibrillation (AFib).
Increased levels of Streptococcus anginosus, a common type of bacteria that usually lives in the mouth and gut, was found in the gut of recent stroke survivors in Japan.
More than one in three parents say their child has faced issues like tooth decay, cavities, stained teeth, gum concerns or tooth pain linked to their oral health routine over the past two years, a national poll suggests.

Fashions shift and now ‘too perfect’ white teeth risk wiping the smile off your face Last summer, I fell and cracked four of my front teeth. Pieces chipped off at unhelpful times, I spat small shards politely into the sink and cursed...
Scientists have now discovered a chemical that plants produce when they're stressed prevents dangerous biofilm from forming. The breakthrough offers potential advances in healthcare as well as preventing equipment corrosion in industrial...
Neural implants contain integrated circuits (ICs) -- commonly called chips -- built on silicon. These implants need to be small and flexible to mimic circumstances inside the human body. However, the environment within the body is...
A new comprehensive literature review of the benefits and challenges of integrating haptics-enhanced virtual reality training, or VR-haptics for short, in dental education curricula highlights the transformative potential of VR-haptics...
Genetic variants that determine the shape of your teeth -- including a gene inherited from Neanderthals -- have been identified by a team of researchers.
Driven by rapid advances in technology and the ever-growing influence of the digital landscape, the art of caring for the physical body and the digital world are becoming increasingly intertwined. The field of cosmetic dermatology is no...
