Abstract
Swabs were taken from 20 patients from root canal (Endodontic Department, Al-Elwiya Specialized Centre for Oral and Dental Surgery), Streptococcus oralis, Streptococcus anginosus, Enterococcus durans, Enterobacter cloacae and Staphylococcus epidermides were identified according to their cultural properties, microscopic examination and biochemical Api and miniapi tests. Antibacterial action was evaluated on these bacterial isolates by using six different concentrations of Salvadora persica(Siwak), Nigella sativa (black seed), aluminum potassium sulphate (alum) and mixture of them, the concentrations are 3.125, 6.25, 12.5, 25, 50 and 100%. At 100% concentration of alum, Salvadora persica, Nigella sativa and the mixture of them, the maximum inhibition zone diameters were 42mm on Enterococcus durans, 27mm on Enterobacter cloacae, 26mm on Enterobacter cloacae and 25mm on Staphylococcus epidermides, respectively.
