Dental papilla anatomy definition
How is papilla formed?
Histological studies showed that the new dermal papillae were derived from dermal sheath cells surrounding upper follicular epidermis, and the new hair matrices were produced from the follicular epidermis..
What is the dental papilla of the ectoderm?
The dental papilla forces the ectoderm of the tooth bud to grow around it.
As this happens, the ectoderm resembles a hat, hence the name cap stage .
At this time, the dental lamina has two prominent parts—an inner and an outer layer..
What is the difference between the dental papilla and the dental follicle?
The dental follicle is the source of cementoblasts, osteoblasts, and fibroblasts, which form the periodontal tissue (ie, cementum, alveolar bone, and periodontal ligament).
Conversely, cells from the dental papilla are the source of the dentin-pulp complex..
What is the papilla in the mouth?
The interdental papilla is the gum tissue found in the space between the teeth.
It helps protect the roots of your teeth and keeps food from getting stuck between your teeth, leading to decay..
What is the papilla tissue between teeth?
Your interdental papilla are what stands between the roots of your teeth and harmful bacteria and food particles.
When healthy, they attach firmly between teeth without leaving gaps.
When gums begin to leave gaps or recede down the teeth, it's a sign that they're not as healthy as they should be.
Triangular shape..
- Each interdental papilla is pyramidal in shape, with the facial and lingual surfaces tapered towards the interproximal col area.
The lateral borders and tip of the interdental papillae are formed by continuation of the marginal gingiva from the adjacent teeth. - The junction between the dental papilla and inner enamel epithelium determines the crown shape of a tooth.
Mesenchymal cells within the dental papilla are responsible for formation of tooth pulp.
The dental papilla is a condensation of ectomesenchymal cells called odontoblasts, seen in histologic sections of a developing tooth. It lies below a cellular aggregation known as the enamel organ. The dental papilla appears after 8-10 weeks intra uteral life.

Embryology
Formation of dental papilla occurs in the Cap stage of Odontogenesis
Differentiation[1]
Ectomesenchymal cells will multiply continuously in a localized area such that when the bell stage of development is reached
Nerve and Vascular Supply during Early Development[1]
Clusters of blood vessels are found branching out around the tooth germ in the dental follicle and going into the dental papilla during the cap
Odontoblast Differentiation[15]
It is paramount to understand how odontoblast differentiate from ectomesenchyma l cells to allow comprehension and explanation of normal

What is the difference between dental and duodenal papilla?
dental papilla ( dentinal papilla) the small mass of condensed mesenchyme capped by each of the enamel organs duodenal papilla either of the small elevations (major and minor) on the mucosa of the duodenum, the major at the entrance of the conjoined pancreatic and common bile ducts, the minor at the entrance of the accessory pancreatic duct
What is the difference between dental papilla and mesenchyme?
The dental papilla later forms the dental pulp tissue and odontoblasts
The other mesenchyme encompasses the enamel organ and the dental papilla to establish the dental follicle, a fibrous sac that supports the tooth germ and will differentiate into the supporting structures of the teeth: the periodontal ligament, cementum, and alveolar bone
In embryology and prenatal development, the dental papilla is a condensation of ectomesenchymal cells called odontoblasts, seen in histologic sections of a developing tooth. It lies below a cellular aggregation known as the enamel organ. The dental papilla appears after 8–10 weeks intra uteral life.dental papilla noun : the mass of mesenchyme that occupies the cavity of each enamel organ and gives rise to the dentin and the pulp of the toothdental papilla (dentinal papilla) the small mass of condensed mesenchyme capped by each of the enamel organs.The rest of the tooth bud, known as the dental papilla, will make the two interior layers of the tooth: the dentin and the pulp. Another sac of cells, called the dental follicle, surrounds both the enamel organ and the dental papilla. This sac contains blood vessels and nerves.Papilla means a small, nipplelike projection, and papillae is the plural form of the word. In this case, they are structures of the gums that project between the teeth. The structure of the interdental papilla is dense connective tissue covered by oral epithelium. Between your incisors, the interdental papillae are shaped like a pyramid.
