Chronic suppurative osteomyelitis can come from improper treatment of acute osteomyelitis, or weak from the toxic bacterial infection. Mandibular molar area occur, the affected area may show different degrees of pain and swelling. Corresponding facial inflammatory infiltration, fistula pus, may be associated with varying degrees of openings is limited. If the sequestrum dental equipment formation of extensive, can lead to pathological fracture. X-ray showed worm-eaten (moth-eaten) bone resorption, there is focal resistance projective. Accompanied by new bone, then bone hardening performance.
Significantly associated with major pathological bone resorption and sequestrum for the formation of purulent lesions. Sequestrum of bone cells mainly disappear, empty lacunae, the lack of trabecular bone around the cells. Sequestrum surrounded by inflammatory granulation tissue, the separation of sequestrum and surrounding tissue. Small sequestrum discharged from the fistula, large sequestrum surrounded by fibrous connective tissue around. Lesions are sometimes seen What oral health should have new ideas around the fibroblasts and capillary proliferation, with varying degrees of lymphocytes, plasma cells, macrophages and neutrophils. After removal of sequestrum, fibrous tissue hyperplasia, differentiated osteoblast, and the formation of reactive new bone.
