The antibacterial efficacy of calcium hydroxide–iodophors and calcium hydroxide–barium sulfate root canal dressings on Enterococcus faecalis and Porphyromonas gingivalis in vitro

Background: A successful endodontic treatment is inseparable from the right choice of root canal dressing. The medicaments would result in patient satisfaction. Enterococcus faecalis (E. faecalis) and Porphyromonas gingivalis (P. gingivalis) are usually found failed treatments. Calcium hydroxide a gold standard dressing that creates an alkaline environment has bactericidal effect. Commercially, there calcium dressings with supporting additions, including hydroxide–iodophors (CH–iodophors) hydroxide–barium sulfate (CH–barium sulfate). Purpose: This study aimed to compare antibacterial efficacy between CH–iodophors CH–barium on E. P. gingivalis. Methods: were obtained commercially. stock culture taken treatment. cultured Petri dishes, for each bacterium, 12 wells made media. Six used group, six group. deployed media dishes. After incubation, inhibition zone diameters measured. An independent t-test was analysis, significance level set at 5%. Results: There significant difference (p = 0.00001). Conclusion: have higher than both
