Anatomy of a congestive (“pocket”) periapical cyst sagittal section image - 30065

Description

This sagittal section illustrates the anatomy of a congestive, or “pocket,” periapical cyst. The affected molar exhibits severe carious decay that extends into the root canal, indicating a long-standing pulpal infection. This type of cyst is often asymptomatic until it enlarges significantly or becomes secondarily infected. Treatment typically involves root canal therapy or surgical intervention, depending on the cyst’s size and response to conventional treatment.
