Screen shots of ABI 7000 SDS software’s output showing standard curves for two of the primers/probe sets used in this study ( T. denticola to the left and A .actinomycetemcomitans to the right). Serial dilutions of plasmid-based positive control were prepared with final concentrations of 5-106 copies/reaction. Assays were run as described in the text. The curves were obtained by plotting log DNA copies count against threshold cycle values (Ct).
