N. deflersiana extract reduces bacterial adhesion. Adhesion assay based on Alamar blue was employed to assess the efficacy of N. deflersiana on T. forsythia, P. gingivalis, and T. denticola adherence. Each bacterial strain were treated with MIC × 0.5, MIC × 1 and MIC × 2 values of the plant extract at 37 °C for 6 h. Control bars specify each untreated bacterial strain, revealed as 0% inhibition. The data was conferred from three independent investigations using means ± SD *** p < 0.0001.
