Abstract:
The purpose of the present study was to investigate the complement activation by lipopolysaccharides purified from Porphyromonas (Bacteroides) endodontalis, Veillonella parvula, and Fusobacterium nucleatum isolated from infected root canals. The rate of consumption of the C3T component of the complement increased remarkably when lipopolysaccharides of more than 10 micrograms were added.
