Abstract The purpose of this study is to clear the difference of histology and elemental composition of the cuspal enamels among the human deciduous teeth. The reground surfaces at the cuspal enamels of them were observed under SEM. The contents of seven elements were analyzed quantitatively with EPMA. It is thought that not only the first zone but also the second zone of the inner enamel in the deciduous molar causes the lateral enlargement of the dental caries along the dento-enamel junction because the second zone of the inner enamel in the deciduous molar was more porous than that in the permanent premolar. It is thought that the cuspal enamel in the deciduous teeth is low calcified than that in the permanent teeth because the contents of calcium and phosphorus in the former were significantly lower than those in the latter. It is considered that the cuspal enamel in the deciduous teeth may include less magnesian whitlocki-te than that in the permanent teeth because the content of magnesium in the former was significantly lower than those in the latter. A relationship was recognized between the complexity level in the histological structure and the elemental composition of the cuspal enamels among the human deciduous teeth.
