Figure 5: (a-d) Structural integrity of pulp stones posttreatment with (PSDA) at different magnifications. SEM images depict the absence of any nodular crystallites due to the decalcification effects of PSDA. (a) The dentinal tubules were open and enlarged due to decalcification. (b-d) The surface topography was found to be smooth as the internal surface of the pulp stone was traced through higher magnification, proving the effect of decalcification. PSDA: Physiological simulated decalcifying agent, SEM: Scanning electron microscopy
