Pathogenicity of bacteria using a simulated root canal system

Co‐production of vascular endothelial cadherin and inducible nitric oxide synthase by endothelial cells in periapical granuloma

“…The structural components of periapical lesions depend on the balance between the microbial factors and the host defences. Many investigators have examined microorganisms in root canals (Haapasalo 1989, Yanagiguchi et al. 1995); however, not only bacterial antigenicity, but also host responses must be characterized.…”
