16 permanent teeth in each jaw:
Location and Function: cover of the tooth crown, the hardest substance in the body.
Composition: 96-98% - hydroxyapatite that is arranged in rods or prisms 4-8 mkm in diameter.
Location and Function: cover of the tooth root, a bone-like material.
Composition: (see Ct/bone.html) - 45-50% - mineral content, Sharpey's fibers (collagen fibers), oxytalan fibers (elastic fibers).
Cells:
Location and Function: major material of the tooth substance, lies deep to the enamel and cementum.
Composition: (see Ct/bone.html) - 70% - hydroxyapatite and odontoblasts (osteoblasts).
Location: pulp cavity, the space within a tooth.
Function: form vascular and neural networks beneath and within the layer of odontoblasts.
Composition: loose connective tissue with blood vessels and nerves.
Function: joining the tooth to its surrounding bone.
