Abstract

A rapid quantitative in vitro assay measured the effects of antiplaque agents and antiserum on growth and sucrose-mediated adherence of radio-labeled S. mutans 6715. Acid production was measured by change in pH. In this assay the primary effect of chlorhexidine and fluoride was bacteriostasis and inhibition of acid production, respectively; the primary effect of dextran, dextranase, and specific antiserum was inhibition of sucrose-mediated adherence.

摘要

一种快速定量体外试验测定了防龋剂和抗血清对放射性标记的变形链球菌6715生长及蔗糖介导黏附的影响。通过pH值变化测定酸生成量。在此试验中，洗必泰和氟化物的主要作用分别是抑菌和抑制酸生成；葡聚糖、葡聚糖酶和特异性抗血清的主要作用是抑制蔗糖介导的黏附。
