The Effectiveness of Remineralizing Agents on Dentinal Permeability

Figure 6

SEM images (3500x) and EDX spectra of treated dentine specimens immersed in artificial saliva for 7 days. (a) GC Tooth Mousse Plus demonstrated modifications in the particles morphology with the deposits being partially removed from the tubules were observed. EDX detected high peaks of Ca and P. (b) Clinpro White Varnish demonstrated a homogenous surface with less partially blocked tubular orifice, whereas EDX revealed high peaks of Ca and P. (c) Duraphat, the surface appeared smooth with only few deposits and nonsignificant closures of tubules were observed, whereas EDX analysis revealed low levels of Ca and P elements. (d) Colgate Sensitive Pro-Relief dentifrice resulted in drastic change of its morphology with much hazy appearance with sparse tubules obliterated by the mineral precipitates. EDX detected high peaks of Ca, P, and K. (e) Biodentine, dentine surface appeared to have a globular morphology with further slight increase in the number of exposed dentinal tubules. An increase in Ca content was observed on EDX analysis.
