【 摘 要 】

Dental plaque, biofilms of microorganisms on tooth surface, plays an important role in the development of caries and periodontal disease. Our aim was to testin vitroantibacterial activity of some herbal extracts againstActinomyces viscosus,Streptococcus mutans,Streptococcus sobrinus,Lactobacillusfermentum,Lactobacillus caseiandEikenellacorrodens. Hydro alcoholic (50:50) extracts of 6 plants were taken using succilate method, then 4 dilutions of extracts (20, 40, 80, and 100% w/v, mg/ml) were put on blood agar media and cultured with one of the bacteria using 4 mm paper discs. Antimicrobial activities of these extracts were examined by disc diffusion method and mean of diameters of inhibition zone of each bacterium in different dilutions was reported. (P<0.05) hydro alcoholic extracts ofPunica granatumandTrigonella foenum-graceumhad strong antibacterial activity respectively, and their antibacterial activities were significantly less than Chlorhexidine and more than Irsha and Miswak. The hydro alcoholic extracts ofScrophularia striataandFumaria parviflorashowed less antibacterial activity in comparison with the first two and it was significantly less than Chlorhexidine and Miswak and more than Irsha.Carthamus tinctoriushad the weakest antibacterial activity. We recommend more studies to demonstrate practical approaches of using natural materials on the oral biofilms.
