The purpose of this article is to inform the general dentist treating the temporomandibular joint complex about fibrositis (fibromyalgia syndrome). Patients may present with spasms in the muscles of mastication, which may mimic joint pain or cause joint dysfunction. Tooth pain, which may mimic endodontic pain, may also be referred from a trigger pain in a muscle.

The major purpose of this study was to determine if 31 patients with fibromyalgia syndrome (FS) reported different pain intensity and Health Locus of Control (HLC) scores than 30 patients with rheumatoid arthritis (RA). Another purpose was to determine the relationship among experienced actual pain (present, usual, worse, least), recalled prior episodes of pain (worse toothache, headache, and stomach ache), HLC orientation, age and the duration of the actual pain. Visual Analogue Scales were used to measure pain intensity. The Health Locus of Control Scale was used to determine external/internal orientation. The results showed that the FS patients reported significantly more intense actual pain, recalled pain for worse toothache and headache, and were more externally oriented than the RA patients. Present pain intensity was significantly correlated to actual intensity ratings, but not to reported earlier experienced pain, except for worse stomach ache in the RA group. The findings' implications for treatment and education are discussed.

There is convincing evidence that acupuncture (AP) is effective for the treatment of postoperative and chemotherapy-induced nausea/vomiting, as well as postoperative dental pain. Less convincing data support AP's efficacy for chronic pain conditions, including headache, fibromyalgia and low back pain. There is no evidence that AP is effective in treating addiction, insomnia, obesity, asthma or stroke deficits. AP seems to be efficacious for alleviating experimental pain by increasing pain thresholds in human subjects and it appears to activate analgesic brain mechanisms through the release of neurohumoral factors, some of which can be inhibited by the opioid antagonist naloxone. In contrast to placebo analgesia, AP-related pain relief takes some time to develop and to resolve. Furthermore, repetitive use of AP analgesia can result in tolerance that demonstrates cross-tolerance with morphine. However, it appears that not all forms of AP are equally effective for providing analgesia. In particular, electro-AP seems to best deliver stimuli that activate powerful opioid and nonopioid analgesic mechanisms. Thus, future carefully controlled clinical trials using adequate electro-AP may be able to provide the necessary evidence for relevant analgesia in chronic pain conditions, such as headache, fibromyalgia, irritable bowel syndrome and low back pain.

The neurobiological mechanisms of acupuncture have been investigated in many cases and provide plausible explanatory approaches for its effectiveness. However, only some of these mechanisms depend on the ,,point-specifity". Evaluation following evidence-based medicine criteria shows level 1 evidence for the efficacy of acupuncture for post-operative dental pain as well as for nausea and vomiting. In addition there are positive results for the efficacy of acupuncture for treating headaches, lumbar spine pain, temporomandibular dysfunction, fibromyalgia, osteoarthritis of the knee and epicondylitis. Acupuncture can be part of a multimodal therapeutic concept for chronic pain disorders with biopsychosocial components.

Acupuncture (AP) is effective for the treatment of postoperative and chemotherapy-induced nausea/vomiting and for postoperative dental pain. Several recent randomized trials have provided strong evidence for beneficial AP effects on chronic low-back pain and pain from knee osteoarthritis. For many other chronic pain conditions, including headaches, neck pain, and fibromyalgia, the evidence supporting AP's efficacy is less convincing. AP's effects on experimental pain appear to be mediated by analgesic brain mechanisms through the release of neurohumoral factors, some of which can be inhibited by the opioid antagonist naloxone. In contrast to placebo analgesia, AP-related pain relief takes considerable time to develop and to resolve. Thus, some of the long-term effects of AP analgesia cannot be explained by placebo mechanisms. Furthermore, it appears that some forms of AP are more effective for providing analgesia than others. Particularly, electro-AP seems best to activate powerful opioid and non-opioid analgesic mechanisms.

Dental pain is among the most prevalent of all pain complaints, and pain is frequently given as a common reason for both avoiding and seeking dental care. Pain is frequently an essential component in the differential diagnosis of many diseases; however, in the elderly, diagnosis is more difficult due to a greater frequency of multiple chronic diseases and an altered pain response. It is important to understand the nature and prevalence of pain in this group, and one should be cautious to avoid the oversimplification that "pain decreases with age." Current studies involving the differences in assessing pain and therapeutic pain control between younger and older age groups are discussed. Pain prevalence is discussed along with herpes zoster, post-herpetic neuralgia, fibromyalgia, toothache pain, burning mouth syndrome, and trigeminal neuralgia as they relate to the elderly. Pain assessment can be made by means of pain scales and specific open- and closed-ended questions. There is evidence that some practitioners may be underestimating the severity of pain in the elderly, and thus not prescribing adequate analgesics when indicated. When analgesics are prescribed, a thorough analysis of the patients' current medications and condition should lead to a customized prescription and dosage.

Nociceptor inputs can trigger a prolonged but reversible increase in the excitability and synaptic efficacy of neurons in central nociceptive pathways, the phenomenon of central sensitization. Central sensitization manifests as pain hypersensitivity, particularly dynamic tactile allodynia, secondary punctate or pressure hyperalgesia, aftersensations, and enhanced temporal summation. It can be readily and rapidly elicited in human volunteers by diverse experimental noxious conditioning stimuli to skin, muscles or viscera, and in addition to producing pain hypersensitivity, results in secondary changes in brain activity that can be detected by electrophysiological or imaging techniques. Studies in clinical cohorts reveal changes in pain sensitivity that have been interpreted as revealing an important contribution of central sensitization to the pain phenotype in patients with fibromyalgia, osteoarthritis, musculoskeletal disorders with generalized pain hypersensitivity, headache, temporomandibular joint disorders, dental pain, neuropathic pain, visceral pain hypersensitivity disorders and post-surgical pain. The comorbidity of those pain hypersensitivity syndromes that present in the absence of inflammation or a neural lesion, their similar pattern of clinical presentation and response to centrally acting analgesics, may reflect a commonality of central sensitization to their pathophysiology. An important question that still needs to be determined is whether there are individuals with a higher inherited propensity for developing central sensitization than others, and if so, whether this conveys an increased risk in both developing conditions with pain hypersensitivity, and their chronification. Diagnostic criteria to establish the presence of central sensitization in patients will greatly assist the phenotyping of patients for choosing treatments that produce analgesia by normalizing hyperexcitable central neural activity. We have certainly come a long way since the first discovery of activity-dependent synaptic plasticity in the spinal cord and the revelation that it occurs and produces pain hypersensitivity in patients. Nevertheless, discovering the genetic and environmental contributors to and objective biomarkers of central sensitization will be highly beneficial, as will additional treatment options to prevent or reduce this prevalent and promiscuous form of pain plasticity.

The authors compared the pain intensity and difficulty experienced in performing activities of daily living (ADL) among 237 patients with orofacial pain. The patients underwent comprehensive examinations and recorded their subjective symptoms on a form (five items for pain intensity and six for ADL-related difficulty). On the basis of the primary diagnosis, the patients were divided into the temporomandibular joint dysfunction (TMJ), myofascial pain (MP), neuropathic pain (NP), and fibromyalgia (FM) groups. The intensity of pain in the jaw/face, tightness in the jaw/face, pain in the neck, and toothache significantly differed among the groups (p < 0.01, Kruskal-Wallis test). Compared to other patients, the FM and NP groups reported greater pain intensity, whereas those in the TMJ group reported lesser pain intensity. The ADL-related difficulty was not significantly different among the groups. Thus, compared to pain due to joint-related disorders, myalgic and neuropathic pain seem to be of higher intensity.
