The current study was investigated the antibacterial and antibiofilm activities of some aqueous medical plants extracts such as Commiphora myrrha leaf , Ziziphus Rugosa Lam. Pericarp leaf , thymus vulgaris leaf and Nigella sativa seeds extracts from Iraq against bacterial isolated from the patients with thermoplastic retainer , Lactobacillus acidophilus, S. mutans, Bacillus subtilis, Acinetobacter baumannii, Raoultella ornithinolytica, Streptococcus thoraltensi, the results of the isolates were showed different responses against CHX depending on the diameter of inhibition zone as L. acidophilus 4.4 ±0.102 , S. mutans 4.6± 0.13 , Bacillus subtilis 4.6± 0.01 , A.baumannii 4.0±0.07 , R. ornithinolytica 3.2±0.00 and S.thoraltensis 2.8 ±0.20. The antibacterial activity of studied extracts were showed positive effects in studied concentration [ 100 mg/ml , 200 mg/ml, 300 mg/ml, 400 mg/ml ] toward the isolates but the concentrations =200 mg/ml of the extracts recorded a good inhibitory effect against isolates comparison of CHX . Furthermore, the results of biofilm assay were showed various strength of biofilm formation, the strong biofilm produces were S.mutans 0.399±0.07 and A. baumannii 0.392±0.98, and intermediated biofilm producers were L. acidophilus 0.279±0.32, B. subtilis 0.268± 0.19, R.ornithinolytica 0.202±0.18. Finally, the weak biofilm producer was recorded in S. thoraltensis 0.180±0.04 but the antibiofilm activity showed all extracts was showed decrease in strength of isolates biofilm formation but the Ziziphus Rugosa extracts was the more effective extract against the performed biofilm formation. The results of this study was reported that the studied Aqueous plant extracts were showed positive antibacterial and antibiofilm effects more than CHX toward the bacteria isolated from the patients with thermoplastic retainers in concentration above 200mg/ml more than CHX activity depending on the diameter of inhibition zone .
