Enamel
摘要
In this chapter, you will learn that enamel, the tissue that covers the dentine in the crown, is the hardest and most mineralised tissue in the body. You will see that it is an acellular tissue whose matrix has a high mineral content, a low content of organic matter, and that it lacks collagen. You will see that the basic structure of enamel is the enamel rod, and that under the microscope, secondary structures can be seen due to variations in the shape, organisation and composition of the rods. You will study the characteristics of the enamel surface. Finally, you will see how amelogenesis occurs and the process of ameloblast differentiation.
