A cementoblast is a biological cell that forms from the follicular cells around the root of a tooth, and whose biological function is cementogenesis, ...
The sheath is also responsible for multiple or accessory roots (medial growth) and lateral or accessory canals in the root (break in epithelium). [3] It is controversial, but HERS may be involved in cementogenesis and the secreting of cementum, or that HERS-derived products might be related to enamel-related molecules, and that these proteins might initiate acellular cementum formation.
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.
In animal tooth development, cementogenesis is the formation of cementum, one of the three mineralized substances of a tooth.Cementum covers the roots of teeth and serves to anchor gingival and periodontal fibers of the periodontal ligament by the fibers to the alveolar bone (some types of cementum may also form on the surface of the enamel of the crown at the cementoenamel junction (CEJ)).
Histologic slide showing a tooth bud. A: enamel organ B: dental papilla C: dental follicle. The tooth germ is an aggregation of cells that eventually forms a tooth. [2] These cells are derived from the ectoderm of the first pharyngeal arch and the ectomesenchyme of the neural crest.

Clinical. Cementoblastoma usually occurs in people between the ages of 20 to 30, equally affecting males and females. [4] It is more commonly found in the mandible compared to the maxilla (3.4:1), with 40% of cases being found in the first mandibular molar area and incisor involvement being extremely rare.
The bell stage is the fourth stage of tooth development which occurs between the eleventh and twelfth week of prenatal development.During this stage of odontogenesis, the epithelial tooth germ forms a bell-shaped structure in the labio-lingual section and is characterised by the formation of the dental sac.
