Fig. 1From: Effectiveness of photon-initiated photoacoustic streaming in root canal models with different diameters or tapersRepresentative microscopic images of each subgroup prepared by #10/.02 and #25/.02 after irrigation with CNI and PIPS in the coronal region (a), middle region (b) and apical region (c). The value of average fluorescence density in the coronal (d), middle (e) and apical (f) regions. ATP levels are shown in g. *p < 0.05, **p < 0.01, ***p < 0.001. Scar bar = 400 μmBack to article page
