Fig 5

Scanning electron micrographs of (a) control, (c) NSSF, (e) NaF and (g) SDF, all images scaled at 10 µm. Dentinal tubules are clearly visible on control specimens, with treated specimens showing tubules filled with remineralising agents at higher magnification images: (b) control, (d) NSSF, (f) NaF, (h) SDF. Higher magnification images showed that tubules in the control (b) specimens were mineral free, and a clear ring of the peritubular dentin was noted. (d) NSSF-treated specimens showed occluded tubules.
