### Dentigerous Cysts: Causes, Symptoms, and Treatments Dentigerous cysts are a type of odontogenic cyst that forms around the crown of an unerupted tooth. These cysts are most commonly found around molars and canines. They are the second most common type of odontogenic cysts after periapical cysts. Although generally mild, dentigerous cysts can lead to severe complications if left untreated. #### Causes Dentigerous cysts occur when fluid accumulates around the crown of a tooth that has not yet erupted. This condition can affect anyone but is most common in people in their 20s and 30s. Genetic factors and certain syndromes, such as nevoid basal cell carcinoma syndrome, can increase the risk of developing these cysts. #### Symptoms Smaller dentigerous cysts may not show any symptoms and are often discovered during routine dental X-rays. Larger cysts, typically over 2 centimeters in diameter, may cause symptoms such as: - Swelling in the jaw - Pain or discomfort - Displacement of teeth - Infection #### Diagnosis Dentigerous cysts are usually diagnosed through dental X-rays, CT scans, or MRI scans. These imaging techniques help to confirm the presence of the cyst and rule out other types of cysts like aneurysmal bone cysts or periapical cysts. #### Treatment The treatment for dentigerous cysts depends on their size. Small cysts can be surgically removed along with the affected tooth. In some cases, a procedure called marsupialization is used. This involves cutting the cyst open and stitching the edges to allow it to drain freely. This method is effective in reducing the chances of recurrence and allows the affected tooth to erupt without obstruction. Other treatment options include: - Complete surgical removal of the cyst and surrounding tissue - Lifelong follow-ups to monitor for recurrence Even small dentigerous cysts should be treated to prevent future complications. Untreated cysts can lead to more severe issues such as infections or displacement of teeth.
