Sentences with word «odontoblasts»

This was due to reduced proliferation, maturation and polarization of the tooth - forming cells called odontoblasts and ameloblasts.

A tooth's natural healing response with an organic matrix requires communication between odontoblasts.

Like bone and other immune cells, odontoblasts require the fat soluble Vitamins A and D in order to release osteocalcin and MGP - protein.

When odontoblasts stop pumping fluid, the hydrostatic pressure in the tooth / pulp is lowered and the normal fluid movement tends to reverse.

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.

Without Sp7, the animals had small, misshapen teeth, and the odontoblasts and ameloblasts failed to mature beyond the pre-odontoblast and pre-ameloblast stage, as measured by absence of mature cell markers for those two types of cells.

The researchers found that Sp7 in normal mice was expressed only in the dental mesenchymal tissue that gives rise to odontoblasts; it was not expressed in the oral epithelium that gives rise to ameloblasts.

The odontoblasts and ameloblasts were fewer in number and showed disorganized alignments.

Altogether, the UAB researchers concluded that Sp7 is obligatory for differentiation of ameloblasts and odontoblasts, but not for the initial tooth morphogenesis.

Co-authors with Javed on the paper, «Specificity protein 7 is required for proliferation and differentiation of ameloblasts and odontoblasts,» are co-first authors Ji - Myung Bae and John C. Clarke, and Harunur Rashid, Mitra D. Adhami, Kayla McCullough, Jordan S. Scott and Haiyan Chen, Department of Oral and Maxillofacial Surgery, UAB School of Dentistry; and Krishna M. Sinha and Benoit de Crombrugghe, M.D. Anderson Cancer Center, the University of Texas.

Pulp contains cells called odontoblasts, which form new dentin if the diet is good.

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.

Each odontoblast has support cells called glial cells.

The tooth is made of dentin (light brown), a bone - like tissue produced by cells called odontoblasts.
