The antibacterial effects of Fluoride against 2 gram-positive and 2 gram-negative bacteria collected from dental plaques of 8 to 10-year old children were evaluated by macrodilution broth and phenolic coefficient method. The majority of bacterial species consisted of streptococcus ?-haemolyticus and neisseria pharynges. Streptococcus ?-haemolyticus, staphylococcus aureus and Escherichia coli were less encountered. The highest MIC rates of fluoride belonged to N pharynges and the lowest to strep ?-haemolyticus. The most and least applied dilution for fluoride belonged to N pharynges and strep ?-haemolyticus. The sensitivity rates were strep ?-haemolyticus>>staph aureus and E.coli> N pharynges.
