摘要: Microorganisms can adhere and colonize on an exposed guided tissue regeneration (GTR) membrane thus developing a nidus of infection. The purpose this study was to compare early bacterial adhesion three different GTR membranes. Expanded polytetrafluoroethylene, polyglactin 910, collagen were used as the test In part I 15 oral microbes their relative ability Six most strongly adherent bacteria (Actinomyces viscosus, Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Streptococcus mutans, Fusobacterium nucleatum, Selenomonas sputigena) selected for II study. membranes placed in tubes containing broth cultures identical concentrations (1 × 108 cells/ml) these at 37°C. Membranes media without controls. At 4, 6, 12, 24 hours, decanted agitated ...
