Dental papilla

The dental papilla is a condensation of ectomesenchymal cells

Cell (biology)

The cell is the structural and functional unit of all known Life organisms. It is the smallest unit of an organism that is classified as living, and is often called the building bricks of life....
called odontoblast

Odontoblast

An odontoblast is a cell of neural crest origin that is part of the outer surface of the pulp , and whose biological function is dentinogenesis, which is the creation of dentin, the substance under the tooth enamel....

Histology

Histology is the study of the anatomy of cell and tissue of plants and animals. It is performed by examining a thin slice of tissue under a light microscope or electron microscope....

Tooth development

Tooth development is the complex process by which tooth form from embryonic cell , cell growth, and erupt into the mouth. Although many diverse species have teeth, non-human tooth development is largely the same as in humans....

Enamel organ

The enamel organ, also known as dental organ, is a cell aggregation seen in histology sections of a developing tooth. It lies above a condensation of ectomesenchymal cells called the dental papilla....
. The dental papilla appears after 8-10 weeks intra uteral life. The dental papilla gives rise to the dentin

Dentin

Dentin is a calcified tissue of the body, and along with tooth enamel, cementum, and pulp is one of the four major components of teeth. Usually, it is covered by enamel on the crown and cementum on the root and surrounds the entire pulp....

Tooth

Teeth are small whitish structures found in the jaws of many vertebrates that are used to tear, scrape, and chew food. Some animals, particularly carnivores, also use teeth for hunting or defense....
