Dental and Oral Biology

This is dental formula for permanent teeth of humans.

It is filled with soft pulp made up of blood capillaries and nerve fibers, therefore this region is sensitive to pain.

These are chisel shaped with sharp cutting edges, used in cutting food.

Open apex has more circulation and the tooth is still in developmental stage. There are viable cells as well in the connective tissue, which can differentiate accordingly. Thus, there is better prognosis.

Lymph drainage is the most important factor as it removes the toxins from pulpal tissues. Thus, it prevents the necrosis of inflamed pulpal tissues.

This is not a result of excessive forces. Blood supply is decreased.

This is the most common reason. As a result of intrusion, pressure is there on the underlying tissues. Thus, chances of disruption of circulation are more.

Phagocytes are released only when caries and pulp come in direct contact.

In pulpal diseases, the signs and symptoms of conditions make the basis for classification.

The response of normal uninflamed pulp is delayed when heat test is done.

Recent research has shown that sensory neuropeptide CGRP is responsible for an increase in blood flow during pulpal inflammation.

This is the most probable reason as with the application of heat, gases expand and cause pain.

If the temperature is maintained, response to cold decreases.

This is a radiopaque condition resulting in bone deposition and is considered as differential diagnosis of condensing osteitis.

All of the above are parts of pulpal classification.
