What potential outcome can occur if the blood vessels at the apex are injured?

Injury to the blood vessels at the apex of a tooth can lead to pulp necrosis. The pulp is the innermost part of the tooth, containing nerves and blood vessels. When the blood supply to this area is compromised due to injury, it can result in a lack of oxygen and nutrients necessary for the cells within the pulp to survive. Over time, this state of deprivation can cause the pulp tissue to die, leading to necrosis.

This condition often manifests clinically as pain, swelling, or a potential abscess and can ultimately result in tooth loss if not addressed. Understanding this process is critical in dental practice because identifying necrotic pulp is essential for determining the appropriate treatment, such as root canal therapy, to try to preserve the tooth or manage any resulting infection.
