Evaluation of the Cleaning Efficiency of 2 Shape, Hyflex EDM and Pro Taper GOLD Systems Using Digital Image Morphometric Analysis (An in Vitro Study)
Keywords:2Shape, Hyflex EDM, ProTaper GOLD, cleaning efficiency, Digital image morphometric analysis.
Aim of the Study: To measure and compare the cleaning efficiency of 2 Shape, Hyflex EDM and Protaper
GOLD rotary systems in removing debris and compare the percentage of remaining debris at three different
levels of root canal by using digital image morphometric analysis.
Material and Method: Total 60 freshly extracted human maxillary first molar with single straight palatal
roots were selected were disinfected in a solution of 1% Thymol for 1 day then the palatal roots were
sectioned at a length of 12 mm from the apex and randomly divided into three groups of twenty teeth :
Group A: Was prepared by 2 Shape file system (Full rotary technique). Group B: Was prepared by Hyflex
EDM file system (Full rotary technique). Group C: Was prepared by Protaper GOLD system (Full rotary
technique) . All systems were used according to the manufacture instructions and roots prepared to an apical
preparation corresponding to size 40 K-file. Sodium hypochlorite (3%) was used as an irrigant for all groups.
Conclusions: 2 Shape system was significantly less effective than Hyflex EDM and Protaper GOLD systems
in eliminating debris from root canals at all levels. There were no differences in the cleaning efficiency
between Hyflex EDM and Protaper GOLD systems at all levels of root canals.
