Physical activity can help reduce gum disease

by

An interesting article titled “Leisure-Time and Occupational Physical Activity Demonstrate Divergent Associations with Periodontitis: A Population-Based Study,” appears in the January 2, 2023, edition of Journal of Clinical Periodontology written by Marruganti Crystal et al. The article discusses how physical activity can help to reduce inflammation, which can potentially decrease the risk of developing periodontitis also known as gum disease. Reducing gum disease has been discussed before on this site, see for example the posts Blueberry extract could help treat periodontitis and Natural Supplements to Improve your Periodontal Health. In the article the authors examine data from the U.S. National Health and Nutrition Examination Survey (NHANES) 2009-2014 database. They retrieved data from 10,679 adults and assessed physical activity from the Global Physical Activity questionnaire which classified activity as either high or low leisure-time or occupational activity. A full-mouth periodontal examination was … Read more

Antibiotic resistance: what should dentists know

by

An interesting article titled “Antibiotic resistance: The silent pandemia” appears in the International Dental Journal on January 12 2023 written by Angel-Orión Salgad Peralvo and et. al. The article discusses a call to action for dentists worldwide to cut back on their antibiotic prescribing habits arguing that 66% of antiobitics prescibed is not warranted. In the article the authors mention that dentists prescribe 10% of all antibiotics in the world. However, the way they see it, antibiotics being overly prescribed can contribute to the worldwide development of antimicrobial resistance. Antibitoics are used in dentistry for preventive purposes and to avoid systemic bacteraemia in patients at risk or to prevent possible bacterial contamination during surgery. Yet the resistance problem increases medical costs and increases mortality. Therefore they feel that dentists should change the way they prescribe antiobitics as the resistance problem … Read more

Detecting Lou Gehrig’s Disease Markers in Teeth

by

An interesting article titled “Early life metal dysregulation in amyotrophic lateralsclerosis” appears in the Annals of Clinical and Translational Neurology written by Claudia Figueroa-Romero and et al. (pp. 872-882, 2020). The article seeks to explore if metal uptake is dysregulated during childhood in people later eventually diagnosed with amyotrophic lateral sclerosis (ALS) also known as Lou Gehrig’s disease. ALS is a disease that leads to paralysis and early death that is characterized by motor neuron degeneration and this causes the brain to lose its ability to initiate and control muscle movement. The majority of cases of ALS have no known cause but both genetic and environmental factors are suspected. In the article the researchers discuss how they collected permanent teeth from patients who had teeth extracted or who had died and were obtained at autopsy. The data included teeth from … Read more

Healthy Mitochondria Could Prevent Alzheimer’s disease Progression

by

Researchers from Ecole Polytechnique Fédérale de Lausanne (EPFL) have found rendering mitochondria resistant to damage can stop Alzheimer’s disease and other diseases caused by amyloid toxicity. Alzheimer’s disease leads to dementia and is becoming more and more of a burden on healthcare systems. The disease is believed to be caused by an accumulation of toxic plaques in the brain and an abnormal aggregation of a beta-amyloid inside neurons. Previous research has looked into treatment for Alzheimer’s disease by reducing the formation of amyloid plaques.  These results were not very promising and now researchers are looking for other treatment strategies such as considering Alzheimer’s disease as a metabolic disease. The researchers looked at mitochondria, which are energy-producing powerhouses of cells, and important in metabolism. The researchers found that by boosting mitochondria defenses against a particular form of protein stress a reduction … Read more

Enamel Composition May Help Predict Tooth Health

by

An interesting article titled “Mesoscale structural gradients in human tooth enamel” appears in the Proceedings of the National Academy of Sciences written by Robert Free and et. al. (vol. 119, no. 52, pp. e2211285119, December 19, 2022). The article explores the hierarchical architecture of human enamel which is integral to the function of human teeth. In the article, discussion is made of how tooth decay has lead to many dental visits due to cavities. There is not much known about how or why many people experience tooth enamel decay or congenital conditions. In the article, the authors used synchrotron X-ray diffraction at submicrometer resolution technology, to observe tiny differences on the order of picometers in the crystallographic parameters of enamel crystallites, which they linked to the presence of ions such as magnesium and sodium or carbonate. Features of enamel at length scales smaller … Read more
