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

Figure 5

SEM images (7500x) and EDX analysis of treated dentine disc immersed in artificial saliva for 10 minutes. (a1) Mp-Mh oxalate shows oxalate precipitate blocking some tubules while others are patent. (a2) EDX spectra show a high peak of Ca and K along with other minerals such as Al, Si, and F. (b1) RMGI XT VAR shows the presence of crystal deposits on the dentine surface with few open tubules. (b2) EDX spectra show a moderate level of Ca, Al, and Si. (c1) LIQ SiO₂ show Si precipitate masking the dentine surface with few open tubules. (c2) EDX spectra show a high level of Ca, P, and F with a moderate level of Si.
