[In vitro evaluation of the antibacterial activity of endodontic drugs]

The antibacterial activity of camphorated phenol, iodine-potassium iodide, aqueous 2% glutaraldehyde, Rockles 4, Cresophene and Terra-Cortril has been tested in vitro against 21 species of bacteria. After 2 minutes of contact between medication and bacteria, Rockles 4, Cresophene, IKI and camphorated phenol inhibited completely all the tested bacteria. Terra-Cortril and aqueous glutaraldehyde 2% even pures were ineffective against all the bacteria species. Only Cresophene remained effective against 4 bacteria species when diluated 100 times.
