Abstract

Incorporation of tetracyline into dental enamels was studied by exposing presoftened enamel slabs to tetracycline-containing mineralizing solutions. Tetracycline was incorporated only when remineralization (assessed by hardness) occurred and the experimental conditions favored the formation of a soluble tetracycline Ca complex. The fluorescence induced by tetracycline incorporation into the enamel slabs was comparable to that reported under in vivo conditions.

摘要

通过将预软化的牙釉质薄片暴露于含四环素的矿化溶液中，研究了四环素在牙釉质中的掺入情况。仅当发生再矿化（通过硬度评估）且实验条件有利于形成可溶性四环素钙复合物时，四环素才会掺入。四环素掺入牙釉质薄片所诱导的荧光与体内条件下报道的荧光相当。
