Effectiveness of XP-endo Finisher on Biofilm Removal from Oval Root Canals

doi:10.13701/j.cnki.kqyxyj.2018.02.003

Abstract

Abstract: Objective: To compare the effectiveness of XP-endo Finisher (XPF) in biofilm removal with passive ultrasonic irrigation (PUI) technique applied respectively or combinational using an infected oval-canal tooth model. Methods: Fifty-four extracted human premolars with single oval canals were selected. After growing multispecies biofilm for 4 weeks, 6 teeth were selected randomly as controls and observed under scanning electron microscopy (SEM)to confirm the biofilm growth. The other teeth were instrumented using Vortex Blue files to size 40/.06 and then assigned to 4 groups (n=12) according to the irrigation protocol: CNI, PUI, XPF, and PUI+XPF. 3% NaOCl was used as the irritant. SEM images were taken from the apical, middle, and coronal third of the canal surface to evaluate the amount of residual biofilm. Results: The ranking of the effectiveness of biofilm removal from the most to the least was: PUI+XPF, XPF, PUI and CNI with no statistical difference between PUI+XPF and XPF (P>0.05). Conclusion: XPF was more effective in removing biofilm from oval root canals than PUI and CNI. The combination with PUI could slightly enhance the efficacy with no significant difference.
