Abstract: In Saudi Arabia, miswak (chewing stick is most commonly obtained from the roots of salvadora persica plant. Several studies have demonstrated the anti-plaque, anti caries and anti bacterial effect of these sticks. The aim of this study was to compare the antibacterial effects of aqueous and alcohol extracts of miswak. Various concentrations of these two extracts were used on seven different types of bacteria using blood agar and ditch plate method up to 48 hours. The pH of the aqueous extract was 5.5 and that of the alcohol extract was 2.8. Data suggested that the alcohol extract has strong microbial inhibitory effect for all tested microorganism at 50% concentration. Aqueous extract was less effective at the same concentration for Strep faecalis. Strep group A, Strep sanguis and Strep mutans. This antibacterial effect was probably due to one or more of the miswak contentswhich included chlorine, trimethylene, an alkaloid, resin and sulfur compounds. The difference between the 2 extracts in their microbial inhibitory effect may be due to deifference in ph of the extracts. The other explanation may be that in the extracted miswak, components of the alcohol extract may be more than those of the aqueous extract.
