Fig. 1From: Antibiofilm activity of epoxy sealer incorporated with quaternary ammonium macromoleculeMean results (± SD) of de-novo biofilm formation amount on the tested concentrations of the quaternary ammonium incorporated epoxy discs and the control (0, 0.4, 0.8, 1.6, and 3.3% w/v). Results are expressed as optical density (OD) at 595 nmBack to article page
