Abstract: INTRODUCTION : a variety of endodontic irrigants are \navailable for endodontic irrigation. Irrigants must be \neffective in removing the smear layer created during \nendodontic therapy as well as eliminating bacteria. \nAIM : This in vitro study tested various alternating \nsequences of sodium hypochlorite, anolyte solution \n(electrochemically activated water), and EDTA for their \nability to do this. \nMETHOD : Forty-eight single canal teeth were randomly \ndivided into six groups, prepared to working length, sterilised \nand inoculated with Enterococcus faecalis. Each group \nwas assigned a different sequence of irrigants. Standard \ncultivation techniques were used to count the colonyforming \nunits at each phase. Two SEM photomicrographs \nof each root’s coronal, middle and apical thirds were \ntaken randomly and the number of patent dentinal tubules \ncounted. Statistical analysis was completed using Oneway- \nANOVA and multiple comparisons. \nRESULTS : Group 6 (n=10) protocol of 5ml anolyte followed \nby 3ml 18% EDTA showed the best smear layer removal \nresults for all thirds of the canal. Chemical irrigation \nsignificantly decreased the intracanal E. faecalis CFUs. \nCONCLUSION : Within the limitations of the study anolyte \nsolution followed by EDTA showed the best smear layer \nremoval. The various sequences of NaOCl, anolyte \nsolution, and EDTA all had similar antibacterial results.
