periodontal cyst meaning
An epithelium-lined sac containing fluid; usually found at the apex of a pulp-involved tooth. The lateral type occurs less frequently along the side of the root.
- It is also known as periapical cyst, apical periodontal cyst, root end cyst or dental cyst.
- Today, most literature agree based on overwhelming evidence that the cyst is predominantly of tooth origin ( odontogenic ), demonstrating findings consistent with periapical cysts, odontogenic keratocysts or lateral periodontal cysts.
