Abstract:Twenty five Streptococcus isolates -were obtained from plaque samples and identified using "biocnemical identification system. The growth rate of these isolates was measured and accordingly eight isolates were chosen which gave a higher growth rate and represented the major Streptococcus species involved in dental disease development. Physiological processes were implicated during this study for the improvement of a type of control upon the growth and metabolism of Streptococcus isolates.
