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
