Figure 2: Scanning electron microscopy image from Uno (a) and Profluorid Varnish (b) treated samples showing a dense, homogeneous organic matrix occluding the dentinal tubules along with the inter-tubular dentin after 1 h. Uno (c) and Profluorid Varnish (d) treated samples showing >50% tubular occlusion after 24 h
