title: [The radiopaque evaluation of NaI radiopaque resinifying agent in vitro].
abstract: OBJECTIVE
  To study the possibility of using radiopaque resinifying agent in resinification of the tooth.
  
  
  METHODS
  65 teeth resinified with radiopaque resinifying agent in vitro were evaluated on X-ray films and through stereomicroscope.
  
  
  RESULTS
  86.11% of the root canals on X-ray films was with good contrast, 95.37% of them was with enough radiopaque length.
  
  
  CONCLUSIONS
  The radiopaque length could really indicate the filling length of the radiopaque resinifying agent in the root canals.
