Pseudoapical cysts of small size can be treated with observation without surgery for the time being, while larger pseudoapical cysts or true cysts need to be surgically removed. 1. Observation: apical cyst if the epithelial lining and the root tip of the internal communication is called pseudoapical cyst, often due to the development of periapical disease, generally smaller pseudoapical cysts, can be treated with root canal therapy, after the introduction of drugs, the cysts can generally slowly become smaller or disappear. 2. Surgical excision: For larger pseudoapical cysts that cannot be treated with medication or true apical cysts that contain a complete epithelial lining and cannot disappear on their own, surgical excision is required. Whether apical cysts need surgery or not can only be confirmed in the hospital based on oral and radiographic examination.
