Abstract
Applications of APF and NaF solutions to extracted human teeth reduced the extent of enamel subsurface demineralization induced by colonization of S. mutans but were ineffective against demineralization by acid lactate buffers. It is concluded that the CaF2 formed on the tooth surface during the treatment is responsible for the protection observed.
摘要
将酸性磷酸氟（APF）和氟化钠（NaF）溶液应用于拔除的人牙，可减少变形链球菌定植引起的牙釉质表层下脱矿程度，但对乳酸缓冲液引起的脱矿无效。得出的结论是，治疗过程中在牙齿表面形成的氟化钙（CaF2）是观察到的保护作用的原因。
