Durability of antibacterial nanocomposite in water-aging
Composite specimens were immersed in distilled water at 37
C for 1, 30, 90, and 180 days. The
water-aged specimens were then inoculated with S. mutans (ATCC 700610). Representative live/dead
staining images (

) showed that CompositeNoF was completely covered by dense live bio-
