牙体牙髓5（Dental pulp 5） Oral medicine qualification examination, oral medicine - intensive sprint class (teacher Bais lecture) A variety of reasons lead to enamel damage, dentin exposure, pain caused by mechanical, temperature, and sweet and sour stimulation. Pathogenesis: Not quite clear. Fluid dynamics: the stimulation of the dentin causes the dentinal tubules to move through the pulp and deliver them to the pulp and cause symptoms. Clinical manifestation： Brushing teeth, eating hard food or hot and cold, sweet and sour stimulation, causing a transient soreness. The tip of the probe passes gently through the sensitive area for examination. Air gun blowing sensitive tooth surface. Treatment： Closed dentinal tubules: drugs, lasers, and methods of repair. Summary Tooth concussion; tooth luxation; fracture of teeth Mild injury of the periodontal membrane, usually without defects in the tissues of the teeth. The tooth is removed from the alveolus by external force. External impact fracture The clinical manifestations of periodontal ligament injuries include mild elongation, discomfort, mild loosening and knock, small amount of bleeding on the gingival margin. Partial dislocation: prolapse, insertion, and displacement of the lip (tongue). Complete dislocation: pain, loosening, and abnormal crown position X-ray film: abnormal periodontal space. Crown fracture Root fracture Combined crown and root fracture X-ray film important diagnosis basis Dental pulp treatment, monitoring, dental pulp activity, partial dislocation Non embedded patients were monitored for dental pulp viability after reduction and fixation. Embedded, reset 2 weeks Hougen tube treatment. Young permanent teeth are embedded and are spontaneously erupted. Complete luxation of teeth Apical development is complete: Rapid treatment, 3 to 4 weeks before replantation, Hougen canal treatment; 2h after the first treatment, root canal treatment, after replantation. Young permanent teeth: Rapid medical treatment, reduc
