it was found that : ( i ) bacterial endotoxin inhibited migration and attachment of hgf to both demineralized and non-demineralized cementum and interfered with the development of oriented cellular structure : ( ii ) the inhibitory effect was significantly more pronounced for non-demineralized than for demineralized cementum : ( iii ) the morphology of hgf attached to endotoxin-treated dental surfaces was altered compared with that of their controls : and ( iv ) bacterial endotoxin inhibited cell attachment to collagen type i and delayed the contraction of collagen gel .
