Dental pulp is the soft, loose connective tissue located in the central portion of each tooth. It has a crown (coronal part) and a root (radicular part). Pulp is a delicate, specialized connective tissue containing thin-walled blood vessels, nerves, and nerve endings enclosed within dentin. Overall, Seltzer and Bender's Dental Pulp, 2nd Edition, is an outstanding year anniversary edition of a classic is an excellent resource for students, residents, and clinicians alike to use to develop and build on clinical protocols for restorative and endodontic procedures that are founded on evidence-based biological by:

Endodontic disease is apical periodontitis, pulp-like tissue by using dental pulp stem cells, a collagen scaffold, and dentin matrix protein 1 after subcutaneous File Size: KB. Also, every time we replace a filling, we get closer to the dental pulp and this puts the tooth at risk of needing a root canal. This study is promising because we could be able to regrow the biological part of the tooth, then cover it with dental restoration, which is .

Dental Pulp Occupies the center of each tooth. Soft connective tissue that supports the dentin. Total 52 pulp organs; Permanent, Primary Total Volume of all permanent teeth pulp organs is cc.
Mean volume of a single adult human pulp is cc. The pulp is the part in the center of a tooth made up of living connective tissue and cells called pulp is a part of the dentin–pulp complex (endodontium).
The vitality of the dentin-pulp complex, both during health and after injury, depends on pulp cell activity and the signaling processes that regulate the cell's : 1. Introduction. Human dental pulp is a connective tissue with unique organization and location.
It is surrounded by hard, inelastic dentin. 1 The dental pulp comprises of cells like fibroblasts, odontoblasts and undifferentiated mesenchymal cells in contact with a complex chain of macromolecules secreted extracellularly, which forms the extracellular matrix (ECM).
2 This matrix provides a Cited by: 1. Types of Pulp. Figure 5 illustrates the regions where the two types of dental pulp are located. Coronal pulp (A) (Lab Image 3) occupies the crown of the tooth and has six surfaces; occlusal, mesial, distal, buccal, lingual and the floor.
Pulp horns (B) are protrusions of the pulp that extend up into the cusps of the age, pulp horns diminish and the coronal pulp decreases in. The effects of retinoic acid on human dental pulp cells in terms of type I collagen and osteocalcin induction were investigated in vitro. Dental pulp cells obtained from the teeth of young patients (age between years) were cultured and subsequently treated with various concentrations of retinoic acid (0, Collagen in the human dental pulp.

Stem cells can be classified into pluripotent (embryonic) or induced-pluripotent stem cells, and adult (also known as tissue-specific) stem cells.7,9 Recently, a number of adult stem cell types have been isolated from dental tissues, including dental pulp stem cells (DPSCs), exfoliated deciduous teeth (SHED), periodontal ligament Cited by: 4.
Dental pulp tissues can be easily collected from clinically extracted human teeth and the individual cells can be enzymatically released from the pulp tissue (Gronthos et al., ). After plating at a low density, DPSCs are able to attach to the culture dish and form a single‐colony cluster after 10–14 days of culture (Gronthos et al.
In view of this, the purpose of this study was to analyze the collagen, the major organic component of dental pulp ECM, in papillae of human tooth germs in different developmental phases.
The maxillas and mandibles of 9 human fetuses ranging from 10 to 22 weeks of intrauterine life were removed and 16 tooth germs (1 in the cap stage, 8 in the. The distribution of collagen type III throughout the pulp tissue from human developing tooth was studied using specific antibodies, immunofluorescence as well as immuno-peroxidase labelling for electron microscopy.
Our results indicate that type III and type I collagen are present in the by: Collagen fibrils and non-collagenous extracellular matrix components may be extracted from the dental pulp. Differences appear between the coronal and radicular pulp after mechanical : Michel Goldberg.
The dental pulp is a unique tissue and its importance in the long-term prognosis of the tooth is often ignored by clinicians. It is unique in that it resides in a rigid chamber which provides. Collagen fibrils and non-collagenous extracellular matrix components may be extracted from the dental pulp.
Differences appear between the coronal and radicular pulp after mechanical preparation. Type I, III, V, and IV collagens have been : Arthur Veis, Michel Goldberg. Collagen type I is the most abundant collagen form designated as collagen fibers in dental pulp.
While the other fibrillar collagens, types III, V, VI, and XI, are seen in the pulp, non-fibrillary type II collagen does not occur. The composition of collagen types in dentin and predentin differs considerably from that of pulp.
followed by the apical papilla mesenchyme. The radicular dental pulp is located in the root, and this is the place where pulp cells differentiate into odontoblasts and in the sub-odontoblastic layer (the so-called Hoehl’s layer) (Figures 9,10,).
The cells slide from the. Dental pulp stem cells (DPSCs) are stem cells present in the dental pulp, which is the soft living tissue within are pluripotent, as they can form embryoid body-like structures (EBs) in vitro and teratoma-like structures that contained tissues derived from all three embryonic germ layers when injected in nude mice.
DPSCs can differentiate in vitro into tissues that have similar.

These adult stem cells play an important role in regenerative medicine both for oral and non oral pathoses thanks to their biological properties such as multipotency, high proliferation rates and accessibility (Yamada et al., ).Beyond natural capacity of response to injury, dental pulp Cited by: 7.
The vitality of the pulp is fundamental to the functional life of the tooth. For this aim, active and living biomaterials are required to avoid the current drastic treatment, which is the removal of all the cellular and molecular content regardless of its regenerative potential.

• Each of these organs has a shape that conforms to that of the respective tooth. • Pulp collagen fibers do not contribute to dentin matrix production.
Current evidence shows that the root canal is filled with pulp-like loose connective tissue with vasculature and nerves after autologous transplantation of pulp stem/progenitor cells, CDSP cells or pulp CD + cells, 5 × 10 5 cells in cell number, with SDF-1 in collagen type I and type III scaffold (Figure 3A-F) (Nakashima, et al., Cited by: 2.
