In March, we presented a pathology case: Read about the case.Here’s the answer and the recommended treatment …
Dentigerous cyst. A dentigerous cyst is “an odontogenic cyst that surrounds the crown of an impacted tooth, caused by fluid accumulation between the reduced enamel epithelium and enamel surface, resulting in a cyst in which the crown is located within the lumen and root(s) outside”. (1) Typically, dentigerous cysts remain asymptomatic, but large growths have been known to produce swelling and pain. The most common teeth involved are the unerupted maxillary and mandibular third molars or maxillary cuspids. (1) The highest incidence occurs during the second and third decades of life. (2) The recommended treatment is complete enucleation, which reduces the possibility of potentially dangerous cells remaining in the region after surgery to form residual cysts, ameloblastomas, or other lesions.

In this particular case, the patient was referred to an oral surgeon and the lesion was removed. Histology confirmed the diagnosis, and the patient has been seen on a regular basis without any complications or recurrent lesions. The bone has filled in nicely and No. 18 is vital. The coronal portion of No. 32 was removed due to the wrapping of the roots around the inferior alveolar nerve.
