title: Canal shaping with one shape file and twisted files: a comparative study.
abstract: OBJECTIVE
  The aim of this study was to compare the shaping ability of two different rotary Nickel -Titanium (Ni-Ti) files, One shape file and Twisted files in a simulated artificial canals.
  
  
  METHODS
  A total of 40 endodontic training blocks were used in this study and divided in two groups consisting of 20 each ( n = 20) and the shaping ability was accessed based on the left over ink stain in the artificial canal.
  
  
  RESULTS
  Image proplus analysis software and stereomicroscope were used for analysing the shaping ability of the files and statistical analysis was done by SPSS software. Twisted files showed better shaping ability compared to one shape file both experimentally and statistically.
  
  
  CONCLUSIONS
  It can be concluded that twisted files shaped the canals better then one shape file.
