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

Figure 6

SEM images (7500x) and EDX analysis of treated dentine disc following the immersion in artificial saliva for 7 days. (a1) Mp-Mh oxalate shows the oxalate precipitates over few dentinal tubules with some patent tubules. (a2) EDX analysis revealed moderate peaks of Ca and K and a low level of P. (b1) RMGI XT VAR show the cobblestone pattern of crystals covering the entire dentinal surface with few open tubules. (b2) EDX analysis revealed a low level of Ca, Al, and Si. (c1) LIQ SiO₂ show interconnected Si precipitate with few open tubules. (c2) EDX analysis revealed high levels of Ca, P, F, and K along with a low level of Si.
