The structure of the blood vessels passing through it is disturbed. Their walls are destroyed, which is accompanied by a sharp bleeding. After a while, the destruction affects other pulpal tissues.

In addition to blood vessels, the nerve fiber undergoes changes. First it is reborn, and then perishes.

The degree of damage depends on the duration of the drug application. The longer it acts, the stronger the effect will be.

The nature of the manifestations will be the same in any case. The pulp will mummify and die.
