Sentences with phrase «dental pulp»
Dental pulp refers to the soft, inner part of a tooth that contains nerves and blood vessels. It keeps the tooth alive and healthy, supplying it with nutrients and providing sensation. Full definition

Tooth trauma or dental caries can lead to the inflammation of dental pulp tissue, the all too familiar pain of toothache, and potentially irreversible damage.
Furthermore, when the authors assessed the subcutaneous implantation of hDPSCs grown on CPD scaffolds, they discovered that PDGF - BB modified cells generated more dentin - like mineralized tissue surrounded by highly vascularized dental pulp - like connective tissue at 12 weeks when compared to unmodified hDPSCs.
A 2006 study of ancient dental pulp (the living center of the tooth made from connective tissue and cells) detected DNA sequences that are similar to typhoid, but the study has been disputed because of possible flaws in its methodology.

Researchers from the laboratories of Xinquan Jiang and Wenjie Zhang (Shanghai Jiao Tong University, PR China) hoped to promote dental tissue regeneration via the application of stem cells resident within the human dental pulp (hDPSCs)[1, 2].
Tooth enamel is the hardest and most highly mineralized substance of the body, and with dentin, cementum, and dental pulp is one of the four major parts of the tooth.
Sharpe suspected he could dramatically boost teeth's natural healing ability by mobilizing stem cells in the dental pulp.
When dentin is seriously injured, stem cells located in the tooth's soft, innermost layer — the dental pulp — morph into cells called odontoblasts, which secrete new tissue.
If so, maybe exposing damaged teeth to drugs that stimulate Wnt signaling would similarly encourage the activity of stem cells in the dental pulp — giving teeth the kind of regenerative superpowers usually seen only in plants, salamanders and starfish.

Since the days of John Hunter it has been known that when the enamel and dentine are injured by attrition or caries, teeth do not remain passive but respond to the injury by producing a reaction of the odontoblasts in the dental pulp in an area generally corresponding to the damaged tissue and resulting in a laying down of what is known as secondary dentine.
Once a tooth is fractured, the dental pulp, which is rich in nerve endings, is exposed.
«If a simple method can be developed that acts to enhance the natural processes of dentine restoration by stimulating tertiary dentine formation, then large injuries that would certainly lead the dental pulp to undergo necrosis could be repaired by enabling reparative dentine to be formed at the site of damage.»
These professionals try to save the tooth when the dental pulp is affected by disease or injured.
