Comparing the Effectiveness of Different Dentinal Desensitizing Agents: In Vitro Study

Figure 7

SEM images (7500x) and EDX analysis of treated dentine disc following citric acid challenge for 3 minutes. (a1) Mp-Mh oxalate resulted in dissolution of the tubular plugs, yet some crystal deposits could be seen within the tubule. (a2) EDX analysis revealed a moderate level of Ca and traces of P. (b1) RMGI XT VAR show loss of crystal structures on the dentine surfaces with few deposits within the tubules. (b2) EDX analysis revealed a moderate level of Ca and K with traces of F, Al, Si, and P. (c1) LIQ SiO₂ show the change in the morphology of the deposits covering dentine surfaces exposing few tubules. (c2) EDX analysis revealed high peaks of Ca and P and a low peak of Mg, Si, and F.
