What Is Cementum?
Cementum is the hard, cement-like material that covers the root surface of the tooth. It is also a vital tissue for dental attachment. The tissue is a light yellow color and is 20 to 50 microns thick near the neck of the tooth. It is thickest at the root apex and is excreted by cementoblasts, which develop from undifferentiated mesenchymal cells that reside in the dental sac. It contains about 45 to 55% inorganic mineral content and 50-55% organic matter, including collagen and glycoproteins.
The coronal portion of the root is covered by acellular cementum, while the apical portion is covered by cellular-like cementum. The two types of cementum have different inorganic contents. The former is composed of hydroxyapatite, a carbohydrate-protein complex, and acid mucopolysaccharides.
By better understanding the structure of cementum, it will be easier for dentists to perform procedures with more confidence. And as long as we continue the research, we can see what kind of effects it can have. While cementum is mostly composed of inorganic substances, it can be a good indicator of tooth health. For the most part, it is present in a healthy root. Therefore, the presence of this layer of bone in the coronal half of the root is important for ensuring that the tooth is in a stable occlusion.
Cementum is a spongy material that covers the outside of a tooth’s root.
It is similar to bone, but does not contain nerves, blood, or Haversian systems. It is essential for dental stability and attaches the root to the periodontal ligament. The cementum primarily covers the root, but it may also cover the crown. It is composed of specialized mesenchymal cells on the outer surface of the tooth’s roots called cementoblasts.
If the it is damaged, the gums and bone in the adjacent tissues may become inflamed and become brittle. Ultimately, the cementum is a crucial structure in the teeth of the mouth. 강남임플란트 It is made up of cells that are found in the cementoblasts. The cells are the specialized cells that form the cementum. The living cells in the periodontal ligament are called cementoblasts.
Eventually, it will be eroded, leaving the dentin exposed. Because the dentin is the main component of the tooth, it contains nerves that connect the tooth to the pulp. During the process of forming a cavity, the dentin and the cementum are continuously exposed. The pulp has small tubes that connect to the alveolus. These cells are sensitive to air, heat, and cold.
The tooth is composed of cementoblasts.
In addition, PDL fibroblasts contribute to the formation of the cementum through the secretion of extrinsic fibers. In addition to these cells, there are also other living cells that form the periodontal ligament. The PDL consists of osteoblasts, which are osteoblasts in a specific environment. However, the cementoblasts in the cementum are more like a type of tissue than the bone matrix, and they respond to osteotropic signals.
It is possible to avoid causing a crack in it by following a good oral care routine. This includes daily brushing, flossing, and interdental brushes. A fluoride-free mouth rinse can help prevent loss of the cementum. These procedures should be carried out if necessary. The aim of the study was to determine the optimal length of orthodontic treatment and the effects of age, tooth movement, and fluoride exposure.
The coronal half of the root is usually covered with acellular cementum, while the apical half is covered with cellular cementum. The two kinds of cementum contain a variety of minerals and inorganic materials. For example, calcium phosphate, hydroxyapatite, and acid mucopolysaccharides are common in coronal cementum. These materials are essential for the strength and durability of the tooth.
It is a complex tissue with a variety of properties and functions. The material of your teeth is largely determined by what is called the apical part. The apical part of your tooth is called the apical part, while the rest of the tooth is covered by the cervical root.
