Missing Teeth Could Lead to More Gray Hair

by

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

by

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. Image by Thor Deichmann from Pixabay Microrobots also offer a new way to collect microbial samples that could be used to diagnose other diseases. Microrobotics relies on … Read more

Brushing Regularly can Help Heart Health

An interesting article titled “Porphyromonas gingivalis, a periodontal pathogen, impairs post-infarcted myocardium by inhibiting autophagosome–lysosome fusion” written by Yuka Shiheido-Watanabe and et. al. appears in the International Journal of Oral Science. This study investigated the molecular mechanisms underlying the adverse effects of P.g. infection on post-MI myocardial remodeling. P.g. infection impaired autophagosome–lysosome fusion, a step in the autophagy process. The study showed that the periodontal pathogen Porphyromonas gingivalis can exacerbate heart damage after a heart attack. The researchers found that the bacterium can accumulate at the site of injury and contribute to tissue damage. The mechanisms for which this occurs is stil under investigation. In an effort to understand how Porphyromonas gingivalis contributes to heart damage, the researchers developed a modified version of the bacterium that lacks a key protein called gingipain. This protein is known to protect cells from … Read more

Burnout amongst dentists and dental students

by

A study exploring burnout in dentists is published in the Journal of Evidence-Based Dental Practice titled “High prevalence rates of burnout and emotional exhaustion among the dental profession,” written by Kelvin I. Afrashtehfar and  Carlos A. Jurado (26 April 2023, 101886). A another study exploring burnout in dental students is published in the Joural of Dental Education titled “Correlates of burnout in predoctoral dental students in the United States,” written by Alex Joseph et. al (19 April 2023). Studies to date have shown that burnout has become a problem for dentists. Burnout is a syndrome of emotional exhaustion, depersonalization, and reduced personal accomplishment. It is beleived to occur in response to chronic stress that is unmanaged. In the first study a systematic review and meta-analysis of 37 studies was performed that resulted in 31 used in the quantitative analysis. These studies demonstrated … Read more

Is it time to ditch the Doctor of Dental Surgery degree?

by

An interesting article titled “Why 2 dental degrees?: Time for unification of degrees and oral health care providers” written by Donald B. Giddon and William V. Giannobile appears in the March 21, 2023 Journal of the American Dental Association. The article calls into question why dentistry is the only major health care profession that has two equivalent degrees: the Doctor of Medicine in Dentistry (DMD) degree and the Doctor of Dental Surgery (DDS) degree. In the article discussion is made of how there is no useful purpose to have two different degrees in dentistry. The authors state that this causes confusion among patients, dentists, and other health care professionals. The authors believe that dentistry should have a single degree, the doctor of dental medicine, which is more accurate to what occurs in dentistry today. The authors say that there are no … Read more
