For Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola, the reaction mix was composed of buffer PCR 1X u50 mMgCL, 10 mM Tris-HCl (pH 9.0 at 25[degrees]C), 1.5 mM Mg[Cl.sub.2] and 0.1% Triton (R) X-100, 0.25 U of Taq DNA polymerase, 1.5 mM of Mg[Cl.sub.2], 0.2 mM from each deoxyribonucleotide and 2 [micro]M from each primer.
