摘要: The purpose of this study was to evaluate the ability two types mineral trioxide aggregate (MTA) seal furcal perforations in extracted human molars using an anaerobic bacterial leakage model. Forty, human, maxillary and mandibular were randomly divided into experimental groups 18, with teeth used as positive controls without negative controls. Experimental group 1 repaired gray-colored MTA 2 off-white-colored MTA. A dual-chamber, anaerobic, bacterial-leakage model assembled. Brain-heart infusion broth yeast extract, hemin, menadione culture for Fusobacterium nucleatum. Two 18 samples leaked three leaked. There no significant difference between preventing F. nucleatum past perforation repairs.
