Is dentin cellular or acellular?
The two main types of cementum are cellular and acellular. The cementum attached to the root dentin and covering the upper (cervical) portion of the root is acellular and thus is called acellular, or primary, cementum.
Where are cementoblasts located?
root
A cementoblast is a biological cell that forms from the follicular cells around the root of a tooth, and whose biological function is cementogenesis, which is the formation of cementum (hard tissue that covers the tooth root).
What is Precementum?
the precementum, is mechanically damaged or scraped off. It is. seen on the wall of the root canal {internal resorption) and on the. external surface of the root [external resorption or cervical resorption) and it may be transient or progressive.
What is Ameloblast cell?
Ameloblast: One of a group of cells originating from the ectoderm from which the dental enamel is developed; an enamel cell. The ameloblasts cover the papilla of the enamel organ.
What are the precursors of Cementoblasts?
The dental follicle is a loose mesenchymal tissue surrounding the developing tooth germ which participates in the formation of periodontal progenitor cells. It is believed that this tissue contains stem cells and lineage-committed progenitor cells or precursor cells for cementoblasts, PDL cells and osteoblasts [56].
What is pulp chamber?
Located beneath the dentin layer (which is the hard tissue right below your enamel) is the pulp chamber, which is the space where your dental pulp lives. Pulp is the soft tissue at the center of your teeth housing connective tissue, nerves, and blood vessels.
What is dehiscence in perio?
18-8) A dehiscence is loss of alveolar bone on the facial (rarely lingual) aspect of a tooth that leaves a characteristic oval, root-exposed defect from the cementoenamel junction apically. The defect may be one or two millimeters long or extend the full length of the root.
What is root dehiscence?
Dehiscence are isolated areas in which root is denuded of bone and root surface is covered by periosteum and overlying gingiva but the denuded are extends through the Marginal Bone. In Dehiscence there is no bone on one side of it (coronally) and is measured with the use of graduated periodontal probe.
