What is the cause of periodontal cyst?

Abstract. Lateral periodontal cyst (LPC), originated from epithelial rests in the periodontal ligament, is a noninflammatory cyst on the lateral surface of the root of a vital tooth. LPC is generally asymptomatic and presents a round or oval uniform lucency with well-defined borders radiographically.

What is the most common oral cyst?

Radicular-necrotic cyst. The most common cyst of the oral cavity is due to the loss of the biological barrier (the pulp of the tooth) that follows from carious lesions or dental trauma (6,13,14) with pulp necrosis and derives from the cellular remnants of the “Malassez”.

How is lateral periodontal cyst diagnosed?

Conclusions. The lateral periodontal cyst can be considered in the differential diagnosis when a radioloucent lesion appears adjacent to the roots of vital teeth. The treatment of choice is surgical removal and subsequent histological evaluation to confirm the diagnosis.

How can you tell the difference between Ameloblastoma and dentigerous cyst?

Although the presence of a tooth within a lucent mass is pathognomonic for a dentigerous cyst, the aggressive features of portions of the mass and the presence of solid enhancing nodular foci were inconsistent with this type of cyst. Thus, ameloblastoma was the primary differential diagnosis.

How are oral cysts diagnosed?

How is it diagnosed? Small dentigerous cysts often go unnoticed until you have a dental X-ray. If your dentist notices an unusual spot on your dental X-ray, they may use a CT scan or MRI scan to make sure it’s not another type of cyst, such as a periapical cyst or an aneurysmal bone cyst.

How do you tell the difference between Ameloblastoma and dentigerous cyst?

What is apical periodontal cyst?

An apical periodontal cyst, also called a radicular cyst, is a mass of soft tissue that is characterized by having a fluid-filled central cavity (called a lumen) that develops around the lower 1/3 of a tooth root, either at the bottom or along the side of the root.
