Human Tooth

This is an image of a piece of dentine acquired using a scanning electron microscope. It shows the dentinal tubules viewed after demineralization using etching with 37% phosphoric acid for 15 seconds and 10% sodium hypochlorite for 1 minute. The colors were obtained by mixing the signals of secondary and backscattered electrons. The mixing is performed using the software FEI Company.
