The percentage of Streptococcus isolated from tooth extraction (20%) and staphylococcus (2.5%) and gram-negative rod(2.5%). The spacemen were collected from the oral cavity and the culture was on mitis salivarius(Himedia/India) agar base, that was determined by biochemical tests by use of blood agar to detect hemolysis, the results revealed the samples were positive.
