At least until the pulp cavity is exposed, as wear rates increase, carious activity decreases.
Is it not even more essential that a dentist should be present to see that the nurse does not penetrate into the pulp cavity?
The pulp cavity inherently provides the body with an immune system response challenge, which makes it very difficult for a bacterial infection to be eliminated.
Also, the overall pulp cavity may be smaller by the addition of secondary or tertiary dentin, thus causing pulp recession.
The infection probably developed because the pulp cavity of a broken dentary tooth was exposed to bacteria.
One group had teeth with acuminate cusps that lacked a pulp cavity; these are called osteodont teeth.
It is a progressive disease, usually starting with loss of cementum and dentin and leading to penetration of the pulp cavity.
The other group had a different cusp arrangement and had a pulp cavity, these are called orthodont teeth.
