Line profile plotted between varying mineral density (g cm− 3) and distance(mm) in the root dentine from surface to subsurface. (a) Group (1) Deionised water; (b) Group (2) BG with 540 ppm F; (c) Group (3) 1,450 ppm F; (d) Group (4) 5,000 ppm F; (e) Comparisons at baseline for all groups; (f) Comparisons after ARCLs in all groups; (g) Comparison after pH-cycling in all groups
