Abstract

This study evaluated the susceptibility to amine fluorides (AmFs) of planktonic and biofilm cultures of Streptococcus sanguis grown with and without sucrose. Cultures were incubated with AmFs (250 mg of fluoride liter-1) for 1 min. The susceptibility of biofilms was less than that of the planktonic form and was further decreased by growth in the presence of sucrose.

摘要

本研究评估了在有或没有蔗糖存在的情况下生长的血链球菌浮游培养物和生物膜培养物对胺氟化物(AmFs)的敏感性。将培养物与AmFs(250毫克氟/升)孵育1分钟。生物膜的敏感性低于浮游形式,并且在蔗糖存在下生长会使其进一步降低。
