Abstract

Acidulated phosphate fluoride (APF), Duraphat or Fluor Protector, was applied to the molar teeth of rats fed a cariogenic diet. The first maxillary molar teeth were subjected to a microbiopsy procedure for fluoride analysis and the mandibular molars scored for caries. All three topical fluoride agents produced a significant increase in the fluoride content of the outermost 5.0 micron of enamel. Only APF produced a significant reduction in caries incidence at all sites.

摘要

将酸化磷酸氟（APF）、Duraphat或氟保护漆应用于喂食致龋饮食的大鼠磨牙。对上颌第一磨牙进行微生物活检以分析氟含量，并对下颌磨牙的龋齿情况进行评分。所有三种局部用氟剂均使牙釉质最外层5.0微米的氟含量显著增加。只有APF在所有部位均使龋齿发病率显著降低。
