Scanning electron microscopic observation on the dentin surface of rat enamel-free areas [0.03%]
扫描电镜下大鼠无釉牙本质表面的观察
H Yamamoto,H Watanabe,H Agematsu et al.
H Yamamoto et al.
Formation of the enamel covering on the dentin of the tooth crown is thought to depend upon the dentin surface structure during the early stages of enamel development. For this reason, observations were made of the dentin surfaces of both t...
