The efficiency of P. gingivalis ATCC 33277 infection in PDLSCs. The infection rate of P. gingivalis in PDLSCs at MOIs of 50, 100, 200, and 500 were 5.83%, 8.12%, 7.77% and 7.53%, respectively, according to the agar plate culture method. The efficiencies of P. gingivalis infection of PDLSCs at MOIs of 50, 100, 200, and 500 were 6.74%, 10.56%, 10.36% and 9.78%, respectively, according to the q-PCR method. The data are presented as the mean ± SD of triplicate experiments. *Significant difference (P < 0.05) compared with agar plate culture method and q-PCR method. # Significant difference (P < 0.05) compared with different MOIs in a group
