title: [Application of decalcified dental matrix in bone reparation].
abstract: OBJECTIVE
  To investigate the effect of decalicified dental matrix (DDM) on healing of traumatic fracture and its side-effect.
  
  
  METHODS
  From June 1997 to December 1998, 42 patients with closed traumatic long bone fracture (36 males and 6 females, aged from 18 to 57 years with an average of 32 years) were divided into two groups randomly; open reduction and internal fixation were carried out in all patients, but the DDM was used only in experimental group. After operation, the body temperature, ALT, and bone union time were observed and recorded.
  
  
  RESULTS
  Following-up 1 to 3 years, the bone union time of experimental group was significantly shorter than that of control group (P < 0.01), there was no significant difference in the temperature and ALT changes between two groups(P > 0.05). No infection occurred.
  
  
  CONCLUSIONS
  DDM can promote the growth of bony callus and enhance the healing of fracture. There is no side-effect.
