Figure 8

SEM image (7500x) of longitudinal section of etched dentine specimen treated with desensitizing agent for 10 minutes. (a) Mp-Mh oxalate exhibits the presence of oxalate crystals within the length of the tubules (arrowhead). (b) RMGI XT VAR shows some mineral deposits within the tubules (arrowhead). (c) The tubules appear to be vacant transversely along its length (arrowhead).
