MRI shows neural differences with teeth grinding and jaw pain

An interesting article titled “Neural Correlates of Tooth Clenching in Patients with Bruxism and Temporomandibular Disorder–Related Pain,” written by Theo J. M. Kluskens and et. al. appears in the Journal of Oral & Facial Pain and Headache (volume 37, Issue 2, Spring 2023, Pages 139–148). The authors sought to measure brain activity in patients with teeth grinding and jaw pain using functional magnetic resonance imaging (fMRI) to investigate whether differences when compared to those without had differennces in pain and/or neural activity. The researchers explored brain activity in 40 patients, 21 of those that bruxism and TMD pain and the remaining 19 patients were controls. The patients were asked to do a tooth-clenching task while they were having their brain scanned in a 3T MRI scanner. Patients had to mildly or strongly clench their teeth for 12 seconds and were … Read more

The Relationship Between Bruxism and Vitamin D

An interesting article titled “Association between bruxism severity and serumconcentrations of 25‐hydroxyvitamin D levels” appears in the 2022 edition of Clinical and Experimental Dental Research written by B. Allaf and M. Abdul-Hak (pp. 1-9). In the article discussion is made of a study that was conducted to investigate the relationship between bruxism, when someone unconsciously clenches or grinds their teeth, and blood levels of 25‐hydroxyvitamin D, commonly known as Vitamin D. Vitamin D is an essenetial vitamin found in foods, like salmon, eggs, and dairy products. Vitamin D can also be obtained from mainly through skin exposure to the sun’s ultraviolet radiation. Obtaining a low amount of vitamin D has been linked to greater risks of diseses ike cancer and heart diasese and could help prevent gum disease. In the study, 100 patients who had dental treatment peformed at Damascus … Read more
