#초록#
The purpose of this study was to analyse topical effects of fluoride agents
experimentally. The author used 2% sodium fluoride, 38% silver diaminefluoride and
1.23% acidulated phosphofluoride gel as fluoride agents, and the objects were 70
extracted, noncarious deciduous and permanent teeth.
After topical application of fluoride agents, crystalline change of the apatitic structure
of enamel was examined by means of X-ray diffractometer, and fluoride
uptake/distribution by means of scanning electron microscope, wavelength dispersive
X-ray spectrometer and energy dispersive X-ray spectrometer.
The obtained results were as follows:
1. Crystallinity of enamel was increased after topical application of fluoride agents, and
the intensity was highest with 1.23% APF gel, next 2% NaF and 38% silver
diaminefluoride in descending order.
2. After application of 1.23% APF gel, differences of crystallinity change were not
observed among deciduous teeth, but crystallinity increased markedly in permanent
incisors.
3. After application of 1.23% APF gel, calcium fluoride concentration was highest at 5
μm deep layer from enamel surface, and almost costant below this layer.
