The author examined the early enamel caries in the proximal surface of extracted de
ciduous teeth with scanning electron microscope,
The results are as follows.
1 Surface structure of early enamel caries of deciduous teeth is different from that of
unaffected sound enamel.
2. Typical findings of surface structure examined are as follows; focal hole, micro
pore, irregular fissure, decalcification of prism core, exfoliation of enamel surface and
granular crystallite.
3. Prismless layers are seen in the enamel surface with in 20¥ìm - 30¥ìm depth of
several deciduous teeth.
