Superoxide dismutase activity in synovial fluids in patients with temporomandibular joint internal derangement.

Purpose: To measure the activity of superoxide dismutase (SOD) in the synovial fluid of patients with temporomandibular joint internal derangement and to show the relationship between the activity of SOD and the severity of the disease.

Materials And Methods: Twenty patients with internal derangement were classified according to Wilkes by clinical radiological examinations. SOD activity was measured by the method based on nitrobluetetrazolium reduction rate.

Healing of bone defects by an osteopromotion technique using solvent-dehydrated cortical bone plate: a clinical and radiological study.

Osseous defects of the jaws following trauma, cysts, infection or congenital deformity may show poor osteogenesis and the affected area may never be completely filled with bone. It is widely accepted in guided tissue regeneration that physically halting soft connective tissue proliferation into bone allows bone regeneration. This concept is called the "osteopromotion principle.
