A lifetime of motion: temporomandibular joints

Article Abstract:

Research is needed to identify the most effective treatments for temporomandibular disorder (TMD). The temporomandibular joint (TMJ) is a synovial joint similar to other joints. Approximately 7 million adults have pain on or near the TMJ. Other symptoms are pain when chewing, limited range of motion, locking of the jaw or clicking and popping sounds. The cause can range from genetic abnormalities of bone, muscle or nerve to arthritis or trauma. Most people require conservative treatment such as soft foods, heat or ice packs, physical therapy and stress reduction. Those with more severe symptoms can be treated surgically.

What we know about pain

Article Abstract:

Chronic pain costs an estimated $50 billion each year in the US but there is still much that scientists do not know about pain. Pain is caused when nerves in an injured part of the body release inflammatory chemicals such as histamine and prostaglandins. Aspirin and non-steroidal anti-inflammatory drugs reduce pain by inhibiting the production of these chemicals. Low-back pain, headache, recurring facial pain, cancer pain and arthritis pain can occur on a chronic basis. Treatments include analgesics, acupuncture, local electrical stimulation, surgery and psychotherapy.

Obesity, brain and gonadal functions, and osteoporosis

Article Abstract:

Dentists can do more to encourage their patients to eat right and exercise. About 20% of all children are overweight, and overweight children are more likely to be overweight adults. Many children do not get regular exercise or eat the right foods. Research has shown that genes only account for 30% to 40% of obesity. The remaining risk is behavioral. Obesity has many serious complications, including heart disease, hypertension, diabetes, arthritis, gallbladder disease and obstructive sleep apnea.
