Description

This detailed anatomical image illustrates a periapical cyst forming near the distal root of a lower molar, following severe tooth decay and pulpal necrosis. The tooth structure shows extensive carious destruction, with the infection having progressed through the pulp chamber and down the root canal. If left untreated, periapical cysts may expand, cause bone resorption, and exert pressure on surrounding structures. Management often involves root canal therapy or surgical enucleation, depending on the cyst's size and whether the affected tooth is restorable.
