Abstract

An application of scanning tunneling microscopy to biological research is presented on observation of micro-structures of a permanent tooth. This observation provides micro-structural images of cross-sectional surface of thin-sliced samples of dentin and enamel of a human permanent tooth within a nanometer region under atmospheric conditions at room temperatures.

The scanning scale used in this study is in 313–10,000 nm for measurements of dental specimens. Several tunneling microscopic images of the dental
