The hyaline layer aids cementum in binding to the dentin. [2] The rationale behind the use of enamel matrix derivative proteins, such as Emdogain, in trying to stimulate reproduction of cementum in periodontal bony defects is based on the presence of enamel matrix-like proteins within the hyaline layer.
The hyaline layer, which has an obscure origin, is a clear layer, unlike the granular layer, with a width of up to 20μm. It can have clinical significance during periodontal regeneration. Circumpulpal dentin forms the majority of the dentin and is generally constant in structure.
The periosteum is a membrane that covers the outer surface of all bones, [1] except at the articular surfaces (i.e. the parts within a joint space) of long bones. (At the joints of long bones the bone's outer surface is lined with "articular cartilage", a type of hyaline cartilage.)
Dentin has microscopic channels, called dentinal tubules, which radiate outward through the dentin from the pulp cavity to the exterior cementum or enamel border. [17] The diameter of these tubules range from 2.5 μm near the pulp, to 1.2 μm in the midportion, and 900 nm near the dentino-enamel junction. [ 18 ]
The mesoderm aids in the production of cardiac muscle, skeletal muscle, smooth muscle, tissues within the kidneys, and red blood cells. The ectoderm produces tissues within the epidermis and aids in the formation of neurons within the brain, and melanocytes. The proceeding graph represents the products produced by the three germ layers.
As the years pass, our bodies get older, and so do our brains. The good news is there are foods that are packed with nutrients that have been shown to support brain health and cognition.
Odontoblast process run in the canaliculi that transverse the dentin layer and are referred as dentinal tubules. [5] The number and size of the canaliculi decrease as the tubules move away from the pulp and toward the enamel or cementum .
Hyaline cartilage is the glass-like and translucent cartilage found on many joint surfaces. It is also most commonly found in the ribs , nose, larynx , and trachea . [ 1 ] Hyaline cartilage is pearl-gray in color, with a firm consistency and has a considerable amount of collagen.
