Antimicrobial efficiency of some antiseptic products on endodontic microflora isolated from gangrenous pulp tissue

The aims of the study are to investigate the bactericidal effect of three antiseptics (chlorhexidine solution, povidone-iodine solution, and Walkhoff solution) and to determine the minimum inhibitory concentration and their effect on different microbial species.

The study was performed on microflora derived from root canals with simple and complicated pulp gangrene and on pure strains of Enterococcus and Candida albicans.

Chlorhexidine and povidone-iodine proved to have antibacterial and antifungal effects if used in the treatment of pulp gangrene and in cases not responding to conventional therapy.

According to the obtained results, the spectrum of antibacterial agents used in infected canal irrigation can be enlarged to include the agents tested.
