title: Effectiveness of two rotary instrumentation techniques for cleaning the root canal.
abstract: An in vitro study was undertaken to compare the efficiency of two rotary endodontic devices for cleaning the root canal wall(s). Only mesial roots of mandibular first molar were used. Forty roots were classified into two equal groups. Group (I) was instrumented using the Canal Finder system, Group (II) was instrumented using Nickel Titanium files. In both groups half of the specimens received a final flush of 17% EDTA and 5.25% NaOCl solutions. Roots were sectioned longitudinally and Scanning Electron Micrographs were taken at three levels (Coronal, Middle and Apical) of each section of the prepared roots. Statistical analysis of the results showed that the Canal Finder system produced a clean canal surface when 17% EDTA and 5.25% NaOCL were used as an irrigating solutions, while Nickel Titanium files had a superior cleaning efficiency than the Canal Finder with either irrigating solution.
