Description

This sagittal section offers a detailed anatomical view of a true periapical cyst, also known as a radicular cyst, forming at the apex of a non-vital lower molar. The image clearly shows extensive crown destruction caused by chronic caries, with the infection having progressed through the pulp chamber and down the root canal. At the root tip, a round, encapsulated cavity has formed — the periapical cyst. This image is an excellent educational resource for understanding the pathological development and anatomical impact of periapical cysts, especially in the context of endodontic and oral surgery training.
