Release of silver ions from different HA–PDA–Ag nanowires (a) and cytotocixity assay by culturing L929 fibroblasts in extracts from different nanowires prepared according to ISO :200 (b) and in corresponding ten times diluted extracts (c). The cell proliferation rates had been normalized to the OD values of the negative control. Each value is mean±SD (n=3). Bars with * and ** indicate values that are significantly different (p<0.05) and highly significantly different (p<0.01), respectively.

(a) Curing temperature of Bis-GMA/TEGDMA/BPO system determined by DSC, and flexural properties of Bis-GMA/TEGDMA composites containing different mass fractions of HA–PDA–Ag-1.0 nanowires: (b) flexural strength; (c) flexural modulus. Each value is mean±SD (n=8). Bars with * and ** indicate values that are significantly different (p<0.05) and highly significantly different (p<0.01), respectively.
