Subjects and methods: 104 samples of tested material (acacia fruits and acacia leaves and olive leaves extracts) and control group were equally divided into 4 groups. The 26 samples of each group were subdivided into 2 equal subgroups; one to test the material antibacterial against Streptococcus mutans and the other to test the material antibacterial against Lactobacillus acidophilus bacteria.
Results: It was found that Amoxicillin have the highest antibacterial effect with highly significant difference in compared to all other groups. While acacia fruits came second followed by acacia leaves and Olives leaves respectively. However there are high significant differences between all groups except that between acacia fruits and acacia leaves against Lactobacillus acidophilus bacteria which showed equal antibacterial activity.
