Substantia eburnea is a Latin term that translates to "ivory substance" in English. It refers to a particular type of material or tissue that closely resembles ivory in appearance, texture, or color. In medical and anatomical contexts, substantia eburnea specifically pertains to a dense and hard substance found within the body, which may resemble the smooth and polished texture of ivory.
The term is commonly used to describe various structures within the human body, particularly in relation to bones and teeth. For instance, substantia eburnea is often associated with the layer of dentin found below the enamel on the crown of a tooth(s). Dentin is a calcified tissue that is similar in appearance to ivory and constitutes the bulk of the tooth structure.
In addition to dental anatomy, substantia eburnea can also be used to describe a type of hard and dense osseous tissue found in certain parts of the skeletal system. This includes areas such as the cortical bone, which forms the outer layer of bones, and areas where bone has undergone significant calcification.
Overall, substantia eburnea refers to a dense and ivory-like substance found within the body, commonly associated with teeth and bones. It serves as an important anatomical term in describing various structures within the human body that share similarities with the physical characteristics of ivory.
Dentine, the ivory forming the mass of the tooth; it is composed of collagen, elastin, calcium phosphate, carbonate, and fluoride, and magnesium phosphate. It is structureless, but contains a large number of fine tubules running in a direction from the pulp cavity to the external surface, in which are found processes (dentinal fibrils, Tomes's fibrils) from the odontoblasts.
