Abstract:

 Introduction: the purpose of this study was to evaluate the efficiency of R Endo, Protaper Universal Retreatment and MTwo R for removal of gutta percha during retreatment.Methods: Sixty extracted anterior teeth were instrumented with Protaper manual files, filled using cold lateral compaction and randomly divided into three groups of 20 specimens each. The root fillings were removed using R-Endo, Protaper Universal retreatment and MTwo R. The amount of filling debris remaining on root canal walls was assessed radiographically . Bucco- lingual and proximal digital radiographs of the roots were captured in JPEG format. The areas of the cervical, middle and apical thirds and the area of remaining filling materials in each third, were outlined and measured by the image J program. The ratios between these areas were calculated as percentages of remaining debris. Data were statistically analysed by means of one-way ANOVA and the post hoc Duncan test to identify the differences between the three techniques.Results: Multiple comparisons of the percentages of remaining filling material in each third revealed significant difference between groups. The apical third had the most remaining material (P=0,000<0,05). Comparison of the three techniques revealed that MTwo rotary instruments left cleaner root canal walls with a lower ratio of remaining material in the apical third (P=0,008<0,05).Conclusion: None of the three devices used guaranteed complete removal of the root filling materials. R-Endo and Protaper Universal Retreatment files were less effective in removing gutta percha from canal walls than MTwo R files.
