Pulp stones are most often seen in:
Aged pulp or chronically inflamed pulp
Young pulp or chronically inflamed pulp
Aged pulp or acute inflamed pulp
Young pulp or acute inflamed pulp
The clinical implication of pulp stones is:
The larger the pulp stone, the more painful the tooth will become
The larger the pulp stone, the more likely it may block access to canals or the root apex
Nothing
The presence of pulp stones helps clinicians in making an accurate diagnosis.
The most extensive branching of the blood vessels occurs in which part of the pulp tissue?
Centre of the pulp
In the root canal
Near the apex
In the subodontoblastic layer
The innervation of the pulp tissue consists of:
