title: [The bacteria detection and drug sensitivity test from infected root canals].
abstract: OBJECTIVE
  To provide bacteriological basis for curing infected root canals with sensitive drugs.
  
  
  METHODS
  We have made bacterial cultivation for 56 cases with infected root canals and drug sensitive test with agar dilution.
  
  
  RESULTS
  The rates of bacteria detection and positive rates from infected root canals were high. Anaerobia and aerobia were sensitive to different kinds of antibiotics.
  
  
  CONCLUSIONS
  Bacteria have close relation to infected root canals. Sensitive drugs should be selected in clinical treatment.
