a Bar charts showing the means and standard deviations of the percentage change of fluid flow rate from baseline obtained from that in the smear layer-covered dentin recorded with different adhesives and application either with or without iontophoresis. b Linear regression analyses comparing the percentage changes of fluid flow after bond associated with that obtained after composite restoration. SE = Clearfil SE Bond; SBMP = Scotchbond Multi-Purpose; SEi = Clearfil SE Bond applied with iontophoresis; SBMPi = Scotchbond Multi-Purpose applied with iontophoresis. P < 0.05 indicates statistical significance
