Fig. 7From: Investigating the residual effect of silver nanoparticles gel as an intra-canal medicament on dental pulp stromal cellsAssessment of DPSCs proliferation rate after seeding on treated dentin surfaces showing the mean ± SD of the following treatment and control groups: 0.01% AgNPs, 0.015% AgNPs, 0.02% AgNPs, Ca (OH)2, non-treated dentin, after 3 and 7 days of culture. Experiments were repeated from 3 different donors and in triplicates (final n = 9) for each group. *p < 0.05Back to article page
