The topology of the enamel is an important topic to study how, on a microscopic level, the surface of the tusk is rough or smooth so that the correct restoration material and method are applied to the tusk. The method of study to find this information will be the SEM; which with the back scattered electrons will tell me the topography and chemical composition on the surface of the mastodon tusk fragment that will be tested, shown in the image below. SEM has better spacial resolution than optical microscopes do with the measuring tool provided by the program and the ability to clearly focus to the limits of detection in this case to a magnification of 1000 the roughness of the surface can be give measurements on how rough the topology.
