Normal and fluorotic primary and permanent teeth were demineralized in 10% EDTA at pH 7 for varying periods of time up to 4 weeks. The fluorotic teeth initially dissolved at a much slower rate than non-fluorotic specimens and appeared to contain more organic material. After almost complete removal of the outer enamel a soft organic layer remained on the dentin surface. This consisted of a fine fibrillar mesh and some more dense material. After four weeks much of the organic material had disappeared leaving only a thin membrane on the dentin surface.
将正常和氟斑牙的乳牙和恒牙在pH值为7的10%乙二胺四乙酸（EDTA）中脱矿长达4周的不同时间段。氟斑牙最初的溶解速度比非氟斑牙标本慢得多，并且似乎含有更多的有机物质。在几乎完全去除外层牙釉质后，牙本质表面留下一层柔软的有机层。这由精细的纤维状网和一些更致密的物质组成。四周后，大部分有机物质消失，仅在牙本质表面留下一层薄膜。
