Unilocular Radiolucencies Of The Jaw: Classification And Features

Write short note on unilocular radiolucent lesions of jaw bone.
Answer. Following are the unilocular radiolucent lesions of jaw bone:

• Radicular cyst
• Residual cyst
• Dentigerous cyst
• Lateral periodontal cyst
• Nasopalatine duct cyst
• Calcifying epithelial odontogenic tumor
• Adenomatoid odontogenic cyst
• Primary bone tumors
• Secondary metastasis tumor
• Eosinophilic granuloma
• Multiple myeloma
• Fibrocemento-osseous lesion
• Stafne’s cyst.

Radicular cyst

It appears as a well-defied unilocular radiolucency with thin hyperostotic borders. The cyst is associated with a non-vital tooth.

Residual cyst

It has a unilocular appearance with thin radiopaque margins. It is round or ovoid in shape and is well circumscribed.

Dentigerous cyst

Usually, the dentigerous cyst is unilocular with wellcircumscribed margins. Radiolucency of the cyst is well defied.

Adenomatoid odontogenic cyst

Radiolucency in adenomatoid odontogenic cyst is well demarcated and has association with the impacted tooth.

Stafne’s cyst

It is a unilocular round radiolucency which is approximately 1 to 3 cm in diameter. At times, Stafne’s defect is bilateral too.
