摘要: Abstract Rats were injected with NaF or SrCl 2 , and sacrificed 5–7 days later. Transverse ground sections of incisors prepared, radiographed, photographed in a polarizing microscope. After demineralization, the same again In normal dentine collagen fibrils oriented perpendicular to dentinal tubules. hypomineralized layers, arranged at 45 ° dentine. This difference orientation encourages search for changes seeding sites apatite. It could also result from an alteration substance surrounding developing fibrils.
