MRI shows neural differences with teeth grinding and jaw pain

by

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

Doctors are feeling pain from prolonged mask use

by

An interesting article titled “Is Prolonged Mask Wearing Associated With Orofacial Pain?” appears in the Journal of Oral and Maxillofacial Surgery written by Vicky Yau, Hong-Yu Liang, and Chenyu Sun (vol. 80, pp. 1875-1877, 2022). The article discuses how with the prolonged use of face masks and surgical respirators, issues of mask associated orofacial pain are now happening for oral and maxillofacial surgeons. This is a new issue due to the use of surgical N95 respirators (also called medical respirators) used by healthcare providers for protection from airborne and fluid transmission and protection from COVID-19. The article discusses how healthcare workers have reported masks-associatedorofacial pain, in the areas of temporalis, zygomaticus, nasalis, and auricularis muscle with the use of N95 masks. N95 masks have a tight facial fit, and provide enhanced filtration against 95% or more of 0.3-mm particles. Orofacial … Read more

Chronic Migraine Sufferers More Prone to Temporomandibular Disorder

by

Researchers at the University of São Paulo in Brazil have found that more frequent migraine attacks lead to more severe temporomandibular disorder (TMD). The temporomandibular joint (TMJ) acts like a sliding hinge connecting the jawbone to the skull, and when the disorder of it occurs, there is often difficulty chewing and joint tension. Previous research studies have indicated that migraine is associated with pain in the temporomandibular joint. This specific research was the first to consider the frequency of migraine attacks when analyzing the connection with TMD. The researchers included 84 women in their early to mid-thirties with 21 suffering from chronic migraine, 32 episodic migraine, and 32 had no history of migraine serving as controls. Chronic migraine means that there are headaches for 15 days per month. Signs and symptoms of TMD were found in 54% of participants serving … Read more

A Study of Outcomes Related to Wisdom Teeth Removal

by

An interesting article titled “A Prospective Study of Clinical Outcomes Related to Third Molar Removal or Retention,” appears in the American Journal of Public Health (April 2014, Vol 104, No. 4) written by Greg J. Huang and et al. The article is a companion article to another also on wisdom teeth in the April 2014 issue of the journal. I discussed the companion article last week in the blog post https://blog.teethremoval.com/practice-based-wisdom-teeth-removal-study/. The article opens by mentioning the controversy surrounding the removal of wisdom teeth. On one side some have advocated for wisdom teeth to be removed to prevent future pathology and minimize risks, others have advocated for wisdom teeth to be removed to prevent lower incisor crowding, and others have argued for wisdom teeth to be removed to prevent periodontal pathology. On the other side some have advocated for wisdom … Read more
