Missing Teeth Could Lead to More Gray Hair

An interesting article titled “Premature gray hair development in the interbrow region owing to the loss of maxillary first molars in young mice” written by Masae Furukawa and et. al. appears in Genes to Cells (published 20 February 2024). The article suggests that losing your teeth might also be affecting your appearance in a way you wouldn’t expect and suggests a link between missing teeth and premature graying hair in the eyebrows.

This study, the first of its kind, investigated the connection between reduced chewing due to tooth loss and the development of gray hair. Researchers extracted upper first molars from young mice and observed them for three months alongside a control group that kept their teeth. Mice missing teeth developed gray hair between their eyebrows, while … Read more

Microscopic Robots Could Revolutionize Stopping Infections

Its possible one day that tiny robots one day can swim through your bloodstream, delivering medication directly to infected cells or removing harmful bacteria. This is the future of medicine, and it’s being made possible by microrobotics. Microrobots are micrometer-sized robots that have the potential to revolutionize healthcare. They can be used for a variety of purposes, including: Researchers at the University of Pennsylvania propose using microrobots to deliver medication and remove biofilms more effectively. Microrobots can be powered intrinsically or extrinsically. Microrobots are still in the early stages of development, but they have the potential to transform healthcare. These microrobots may be used to target infections stuck in areas, such as between the teeth. The technology may reduce antimicrobial resistance.

Giving social support may help to lower inflammation and improve health

An interesting article titled “Perceived social support-giving moderates the association between social relationships and interleukin-6 levels in blood,” appears in the 2022 edition of Brain, Behavior, and Immunity (no. 100: pp. 25-28) written by T. Jiang and et al. The article seeks to explore if perceived social support-giving (i.e. the belief that one can be available to give social support to others) moderates associations between social relationships and inflammation. Thus the article looks at the willingness to give social support to others such as family and friends instead of just receiving help from those same people. In the article, the researchers looked at data from the National Survey of Midlife Development in the U.S. (MIDUS II) and in particular 1054 healthy middle-aged adults between 34 and 84 years old. The data contained questionnaires on social integration, support-availability from others, positive relations … Read more

Association between brain and periodontitis

An interesting article titled Periodontitis causally affects the brain cortical structure: A Mendelian randomization study written by Mengqiao Wang and et. al. appears in the Journal of Periodontal Research, published December 7, 2023. The authors sought out to estimate whether genetically proxied periodontitis impacts the brain cortical structure. The lines between oral and neurological health blur further, as the article reveals that gum disease isn’t just a dental concern, but can potentially impact the way our brains are wired. The researchers found a causal link between periodontitis, also known as gum disease, and changes in the structure of the brain’s cortex. This is the first study to show such a connection, and may open a new avenue for understanding neurological diseases. To uncover a potential cause-and-effect link between gum disease and brain structure, researchers employed a clever technique called “Mendelian randomization.” … Read more

Stannous Flouride Combination Can Eliminate Dental Cavities

An interesting article titled “Iron oxide nanozymes stabilize stannous fluoride for targeted biofilm killing and synergistic oral disease prevention” written by Yue Huang and et. al. appears in Nature Communications, vol. 14, No. 6087, 2023. The article discusses a potent therapeutic synergism using approved agents while providing facile stannous fluoride stabilization, to help prevent oral disease and dental caries (cavities). The authors describes a new method for using iron oxide nanozymes to stabilize stannous fluoride and improve the ability to kill biofilms. Biofilms are communities of bacteria that can form on teeth and other surfaces in the mouth. They are difficult to remove and can lead to tooth decay and other oral diseases. Stannous fluoride is an effective antimicrobial agent, but it is unstable and can be difficult to deliver to the site of infection. Ferumoxytol, an iron replacement, stabilizes stannous fluoride … Read more
