Determination of the minimum inhibitory concentration (MIC) of CatDex (a) and CHX (b) against S. mutans UA130 and P. gingivalis W83 (). At all concentrations, CatDex showed a significant impact on S. mutans, and P. gingivalis growth also demonstrated a similar effect except at 25 μmoL L⁻¹, both compared to CHX 1340 μmoL L⁻¹ ().
