Fig. 4
Representative SEM images showing DPSCs adhesion to the dentin surfaces in 0.01% AgNPs (a), 0.015% AgNPs (b), 0.02% AgNPs (e), Ca (OH)2 (g), Non-treated dentin (i) after 3 days and 0.01% AgNPs (b), 0.015% AgNPs (d), 0.02% AgNPs (f), Ca (OH)2 (h), Non-treated dentin (j) after 7 days of culture. Magnifications are × 500. Insets in each image represent higher magnification at ×2000 showing dense cell attachment on the dentin surfaces in all groups
