Preliminary data have suggested that taurolidine may bear promising disinfectant properties for the therapy of bacterial infections. However, at present, the potential antibacterial effect of taurolidine on the supragingival plaque biofilm is unknown. To evaluate the antibacterial effect of taurolidine

Fluorescein and carboxyfluorescein have found recent application as probes of intracellular pH. The present study examines several parameters required for interpretation of the spectral information derived from fluorescein and carboxyfluorescein generated intracellularly from their permeant diacetate derivatives. Coefficients were determined
