Answer

Pulp Cavity of Teeth: Lined by Odontoblasts

The correct answer to the given question is option 'A', which states that the pulp cavity of teeth is lined by odontoblasts. Let's discuss in detail why odontoblasts are responsible for lining the pulp cavity of teeth.

The pulp cavity is the central space within the tooth that contains the dental pulp. The dental pulp is a soft connective tissue that consists of blood vessels, nerves, and cells called odontoblasts. These odontoblasts are responsible for the formation and maintenance of dentin, which is the hard, calcified tissue that makes up the majority of the tooth structure.

Odontoblasts are specialized cells that are located at the periphery of the pulp cavity, adjacent to the dentin. They have long processes that extend into the dentin and are responsible for the secretion of dentin matrix. The dentin matrix is composed of collagen fibers and mineralized substances, which give the tooth its strength.

The odontoblasts are responsible for the production of dentin throughout the life of the tooth. They continuously lay down new layers of dentin on the inner surface of the dentin, pushing the pulp cavity further towards the center of the tooth. This process helps to protect the pulp tissue and maintain the integrity of the tooth.

The odontoblasts also play a crucial role in the defense and repair mechanisms of the tooth. When the tooth is exposed to external stimuli, such as dental caries or trauma, the odontoblasts can respond by initiating the formation of reparative dentin. This reparative dentin helps to seal off the affected area and protect the underlying pulp tissue from further damage.

In summary, the pulp cavity of teeth is lined by odontoblasts. These specialized cells are responsible for the formation and maintenance of dentin, the production of reparative dentin, and the protection of the pulp tissue. They play a vital role in the overall health and function of the tooth.

Answer

Odontoblasts are the dentine forming cells, derived from mesenchyme of neural crest origin, lining the pulp cavity of a tooth. Odontoblasts are arranged in a peripheral layer in the dental pulp.
