S6were obteined from each root : two coronal third slices, two medium third slices and two apical third slices.The sample was randomly distributed randomly in 3 different study groups: NaOCl 5.25% for 1minute (3ml), NaOCl 5.25% for 5 minutes (3ml), NaOCl 5.25% for 20 minutes (3ml) plus EDTA 17% for 1 minute (3ml).Each specimen acted as its own control specimen and was inmersed in the tested solutions for the estimated time.All specimens were cleaned for 10 seconds in an ultrasonic device before and after treatment with the solutions.The roots were inspected under Fourier Transform Infrared spectroscopy (Excalibur 3010 FT-IR, Varian, Walnut Creek, USA) to evaluate the inorganic and organic composition.The statiscally tests were Friedman´s and Wilcoxon´s Test to assess changes in the same radicular third.The Kruskal-Wallis´and Mann-Whitney´s were used to evaluate changes among root dentin thirds. ResultsNo changes were registered in the phosphate group in the 3 study groups.In the NaOCl 5.25% group, Amida III and Amida I significantly decreased in the apical third.The Amida I also decreased in the medium third too.In the EDTA 17% group, Amida III and Amida I were increased in the apical third. ConclusionsThe inorganic component of the root dentine is not affected by the irrigation solutions.NaOCl 5.25% and EDTA 17% caused changes in the organic component of the root dentin, specially in the apical third.
