الملخص EN

In this study some bacterial species were isolated and identified from dental plaque and healthy teeth (control) in children (1 – 5) years that included pathogenic and non pathogenic staphylococci , streptococcus spp.

Escherichia coli and proteus spp.

The frequency of these isolates was in comparable values in males and females , also we studied the antibacterial activity of oils extracts from Brassica nigra seeds and some antibiotics by disk diffusion methods Results revealed that the isolates were more sensitive to oils alcoholic extracts compared with aqueous extracts and they were more sensitive to ciprofloxacin and Gentamicin compared with other antibiotics.
