Of these, cementum is the only one that is a part of a tooth. Periodontal ligaments connect the alveolar bone to the cementum. Alveolar bone surrounds the roots of teeth to provide support and creates what is commonly called an alveolus, or "socket". Lying over the bone is the gingiva or gum, which is readily visible in the mouth.
Cementum situated around a human molar The cementum is the surface layer of the tooth root, covering the dentin (which is labeled B).Rather than being a passive entity like paint on a wall, cementum is a dynamic entity within the periodontium.
On the maxilla, the alveolar process is a ridge on the inferior surface, making up the thickest part of the bone. On the mandible it is a ridge on the superior surface. The structures hold the teeth and are encased by gums as part of the oral cavity . [ 12 ]
Cementoblasts form the cementum of a tooth. Osteoblasts give rise to the alveolar bone around the roots of teeth. Fibroblasts develop the periodontal ligaments which connect teeth to the alveolar bone through cementum. [4] Tooth development is commonly divided into the following stages: the bud stage, the cap, the bell, and finally maturation.
In dental anatomy, the cementoenamel junction (CEJ) is the location where the enamel, which covers the anatomical crown of a tooth, and the cementum, which covers the anatomical root of a tooth, meet. Informally it is known as the neck of the tooth. [1]
The hypocone is found on the distal lingual side of the tooth. It fits into the grooves of the lower dentition and is an adaptation for the overall grinding and tearing of foods using the occlusal (chewing side) of the tooth surface during occlusion or mastication (chewing).
A root canal is the naturally occurring anatomic space within the root of a tooth.It consists of the pulp chamber (within the coronal part of the tooth), the main canal(s), and more intricate anatomical branches that may connect the root canals to each other or to the surface of the root.
The periodontium is the tissue that surrounds and supports the teeth. It includes the connective tissue and overlying keratinised membrane lining the oral cavity that surrounds the teeth, the periodontal ligament, cementum which provides a protective covering for the root surface and supporting alveolar bone.
