title: [Comparison of the clinical effects of three root canal treatments.].
abstract: OBJECTIVE
  To compare the clinical effects of three root canal treatments.
  
  
  METHODS
  The patients were randomly divided into A,B,C groups. Group A: profile preparation of the root canal, then the root canal was filled with maillefer thermafil. Group B: profile preparation of the root canal, iodoform cataplasm and gutta percha point was used to fill root canal. Group C: preparation of the root canal with stainless steel hand-operated root canal magnified instrument, iodoform cataplasm and gutta percha point was used to fill the root canal.
  
  
  RESULTS
  Through X ray and clinical evaluation, the root canal therapy result in group A was superior to group B, group B was superior to group C.
  
  
  CONCLUSIONS
  The work efficiency of preparative instrument of profile flexible nickel-titanium root canal is high. The successful rate of maillefer thermafil for results root canal therapy is superior to the other methods. Root canal preparation by profile can get satisfying effects.
