Percentages of cell viability after exposure to dead and living bacteria. (A) Percentages of cell viability in presence of living P. intermedia, dead P. gingivalis, living P. gingivalis and the combination living P. intermedia plus dead P. gingivalis. (B) Percentages of cell viability exposed to living P. gingivalis, dead P. intermedia, living P. intermedia and the combination living P. gingivalis plus dead P. intermedia. Control contains only cells without bacteria. *Designates a statistically significant decrease in cell viability respect to control (p < 0.05). #Designates a statistically significant decrease of cell viability respect to all conditions (p < 0.05).
