Effective cleaningofroot canals was evaluated.One hundred distal canals of lower molars were instrumented with R50 and divided into 10 groups with an antimicrobial, a chelator and an agitation device. The groups were: G1 (CHX 2% + EDTA 17% + Canal brush); G2 (CHX 2%+ EDTA 17% + EasyClean); G3 (CHX 2% + EDTA 17% + Irrisonic); G4 (CHX 2%+ EDTA 17% / Canal brush + EasyClean); G5 (CHX 2%+EDTA 17% / Canal brush + Irrisonic); G6 (NaOCl 2,5%+EDTA 17% / Canal brush); G7 (NaOCl2,5%+ EDTA 17%/ EasyClean); G8 (NaOCl 2,5%+ EDTA17%/ Irissonic); G9 (NaOCl 2,5%+EDTA 17% / Canal brush + EasyClean) and G10 (NaOCl 2,5%+EDTA 17% / Canal brush + Irrisonic). Three cycles of 20 second agitation were performed, with 2 ml of each substance. The roots were longitudinally sectioned for scanning electron microscopy analysis.Statistical difference was observed betweenthecervical and apical thirds in G4, G5 and G6 (p<0.05); and betweenthe middle and apical thirds in G2 (p<0.05). None of the protocols ensured effective cleaning of the root canal, and in all groups the apical portion was more critical to clean.
