Q
The dental pulp has some features that makes its irculation unique. What are some of these features?
A
The compliance of the pulp is low as it resides in an unyielding, calcified wall.
The dedntal pulp is a firm and resilient connective tissue (intrapulpal pressures are limited to the site of infection)
Terminal arteries supplying it fall within the mirocirculatory range
- this may restrict blood supply making it difficult to combat infections
The tooth acts as a bridge between the sterile jawbone and the mouth.
