Abstract


The purpose of this study was to evaluate by diaphanization the cleaning ability of walls of flattened root canals prepared with three different instruments. Thirty lower incisors, which had their root canals filled with India ink after coronal access and determination of the work length, were selected. The samples were randomly divided into three groups of 10 teeth each, according to the instrument used in the preparation: Group 1– hand files instrumentation; Group 2– instrumentation with ProTaper Universal rotary files; Group 3 – instrumentation with iRace rotary files. After instrumentation, the teeth were diaphanized and evaluated by cleaning ability, analyzing the amount of dentin walls in which India ink was not removed. When performing the Kruskal-Wallis test (p>0.05) there were not statistical significant differences between the groups, as the arithmetic average of the scores at cervical, middle and apical thirds. None of the instruments used in root canal preparation of flattened root canals was able to perform a complete cleaning of the dentin walls.
