在幼小年龄便有变形链球菌群(Mutans strepto-cocci,MS)定植的儿童具有较高的患龋率,而大多数孩子通过母亲这条途径获得MS。木糖醇作为一种非致龋甚至抑龋的糖替代物,具有特殊的抑制MS的效应。短期的日常使用,木糖醇能减少菌斑和刺激性全唾液中MS的计数水平;长期使用,菌斑中抗木糖醇的MS增多,易从菌斑脱落进入唾液。 作者早期已报道了母亲日常使用木糖醇与MS母婴传播发生可能性的显著减少有关(2年期)。研究对象为在怀孕期间均显示唾液中高水平MS的 Children at a young age who have been colonized by Mutans strepto-cocci (MS) have a high prevalence of caries, whereas most children acquire MS through this route. Xylitol, as a non-carious or even caries-deprived sugar substitute, has a specific inhibitory effect on MS. Short-term daily use, xylitol can reduce plaque and irritating salivary MS count levels; long-term use, anti-xylitol MS increased plaque, easy to fall from the plaque into the saliva. The authors have reported earlier that mothers' daily use of xylitol is associated with a significant reduction in the likelihood of mother-to-child transmission of MS (2 years). The subjects studied were high-level MS in saliva during pregnancy
