title: [Clinical evaluation of root canal obturation of GuttaFlow].
abstract: OBJECTIVE
  To evaluate the clinical effects of GuttaFlow on root canal obturation.
  
  
  METHODS
  314 teeth were divided into 2 groups randomly.The GuttaFlow plus gutta-percha cone was used to fill root canals in the experimental group and Endomenthasone sealer plus gutta-percha cone was used in the control group. The filling time, the effect of root canal obturation by X-ray, the occurrence of pain during the filling operation and after treatment were recorded. The data was analyzed with SPSS13.0 software package.
  
  
  RESULTS
  The filling time in the experimental group was significantly less than that in the control group by rank sum test (P<0.01).There was no significant difference between the two groups on both the root filling effect and occurrence of pain by Chi-square test (P>0.05).
  
  
  CONCLUSIONS
  The root canal obturation of GuttaFlow plus gutta-percha cone is an easier and faster filling system for root canals. There is no significant difference on root filling effect and occurrence of pain between the GuttaFlow and the normal lateral compaction technique. It is one choice of clinical techniques for root canal obturation.
