Abstract

The effects of low concentrations of these fluorides on Streptococcus sobrinus, Streptococcus mutans, Streptococcus salivarius, Streptococcus mitior and Streptococcus sanguis were investigated. Without fluoride, mutans streptococci (Strep. mutans and Strep. sobrinus) produced more acid than the other strains; both fluorides reduced acid production in all strains. NaF had little effect on growth; SnF2 decreased growth in all strains, most evidently in the Strep. mutans. In all growth conditions, Strep. sobrinus produced the most alkali-soluble glucan. Both fluorides enhanced alkali-soluble glucan production in mutans streptococci while only SnF2 enhanced this in the other streptococci.

摘要

研究了低浓度的这些氟化物对远缘链球菌、变形链球菌、唾液链球菌、轻链球菌和血链球菌的影响。在无氟的情况下，变形链球菌（变形链球菌和远缘链球菌）比其他菌株产生更多的酸；两种氟化物都降低了所有菌株的酸产生量。氟化钠对生长影响很小；氟化亚锡降低了所有菌株的生长，在变形链球菌中最为明显。在所有生长条件下，远缘链球菌产生的碱溶性葡聚糖最多。两种氟化物都增强了变形链球菌中碱溶性葡聚糖的产生，而只有氟化亚锡增强了其他链球菌中碱溶性葡聚糖的产生。
