Recent advances in temporomandibular disorders and orofacial pain
Article Abstract:
The temporomandibular joint (TMJ) is located in the lower jaw. Abnormalities of the TMJ that cause pain during chewing and other facial movements are receiving increasing attention. Guidelines regarding TMJ disorders have been developed recently for dentists and include principles for the diagnosis and care and treatment of TMJ disorders as well as educational guidelines for the profession. Epidemiological studies have revealed much information about the signs and symptoms of TMJ disorders, the prevalence of these disorders, and populations more likely to be affected. The American Dental Association has developed a classification system using epidemiological information that includes diagnostic criteria for TMJ disorders. Further research is needed to establish the reliability of these proposed criteria, but they promise to be very useful to dentists. Advances have also been made in the understanding of chronic pain affecting the face and jaw. This type of pain is continuous and has no apparent biological cause, in contrast with the acute pain that is most often associated with TMJ disorders. People who suffer from chronic pain tend to experience more problems in their lives. While these problems can result from the constant pain, they may also be caused in part by lifestyle issues. Research has indicated that chronic pain tends to involve biological, psychological and social factors, rather than being a simple medical problem, and therefore treatment must include consideration of these other aspects as well. Recent breakthroughs in understanding the mechanisms of pain have led to more complete treatments. Dentists must keep abreast of advances in the field of TMJ disorders and orofacial pain so that they can provide their patients with the best possible care.

The prevalence and treatment needs of subjects with temporomandibular disorders
Article Abstract:
Disorders of the temporomandibular joint (TMJ), the joint between the jaw bone and the skull, are characterized by pain and dysfunction of jaw motion. There are few reports on the incidence of temporomandibular joint disorders (TMD) and the need for treatment. Specific diagnostic criteria were used to determine the incidence and the severity of muscle and TMJ disorders in 269 female nursing students. The subjects completed a questionnaire and were given a clinical examination. The most frequently reported symptom was noise on TMJ motion. Although 69 percent of the students exhibited clinical signs of TMD, symptoms were severe enough to warrant treatment in only 6 percent. There was a high incidence of pathosis, or abnormal condition, but a correspondingly low level of symptomatology. Clicking sounds in the TMJ represent a benign condition in asymptomatic patients. The major source of pain appears to be the jaw muscles. These findings support conservative management before considering surgery for TMD.

The relationship between clinical and MRI findings in patients with unilateral temporomandibular joint pain
Article Abstract:
Palpation of the jaw joint is more effective than an MRI scan for diagnosing temporomandibular joint disorder, according to a study of 85 patients. MRI often showed fluid in the joint, but the presence of fluid did not always correspond to pain upon palpation.
