Enterococc faecalis considered to be the mostresistant bacteria of the root canal, in the presentstudy we used two types of root canal disinfectant toshow their effect on this type of bacteria, the firstis the diode laser and the second NaOCl solution withspecial concentrations and times. the study conductedon human decoronated extracted teeth, adjusted with13mm root length, filled with a suspension of E.faecalis, Samples were divided into 14 groups eachgroup consisted of 10 prepared roots, sixty sampleswere irrigated with NaOCl solution at differentconcentrations (0.5%, 2.5% and 5.25%) at twoselected times (2 minutes and 5 minutes) for eachconcentration.Sixty samples were irradiated at different powers (2W, 2.5W and 3W); each power at thetotal irradiation time 30 and 60 seconds. Whencomparison was made between NaOCl irrigant and diodelaser in a combination among differentconcentrations, powers and times the result showedthat 5.25% NaOCl at both 2 minutes and 5 minutes hadthe...
