How to Manage Pain Patients in Dental Practice

An interesting article appears in J Can Dent Assoc 2012;78:c83 titled “Neuropathic Orofacial Pain Patients in Need of Dental Care,” written by Gary D. Klasser and Henry A. Gremillion. It was posted online on August 17, 2012, over at http://www.jcda.ca/article/c83. The abstract of the article states “Dental pain is a common complaint among the general population. Most pain is a result of traumatic injury or bacterial infection in pulpal and periapical tissues, and dental practitioners are successful at diagnosing these conditions and providing prompt relief. However, in some cases, patients continue to complain of persistent pain, which may be categorized as neuropathic. These people may avoid or neglect routine dental treatment or interventions to prevent precipitation, perpetuation or exacerbation of their pain condition, and practitioners may have to modify their procedures when managing the dental needs of this unique population.” … Read more

Electric Stimulation of Brain Releases Powerful Painkiller

Researchers have been exploring delivering electricity through sensors on the skulls of chronic migraine patients and have found a decrease in the intensity of pain of their headaches. A recent study published in Frontiers in Psychiatry has shown that when electricity is sent to certain regions in the brain of a patient with chronic, severe facial pain it releases an opiate-like substance and powerful painkiller. In the study, researchers administered a radiotracer that reached important brain areas in a patient with trigeminal neuropathic pain. They then applied electrodes and electrically stimulated the skull right above the motor cortex  for 20 minutes during a PET scan which is known as transcranial direct current stimulation (tDCS). The radiotracer was designed to measure the local brain release of mu-opioid, a natural substance that alters pain perception. The researchers argue that this is the … Read more
