What is it about?

The paper reported a 13-year-old female student who presented with purulent discharge posterior to the upper right second molar with a bad taste and foul odor. Radiographic examination revealed a maxillary third molar tooth located in the right maxillary sinus with a hyperdense lesion surrounding the crown, obliterating the sinus cavity. Both the tooth and the associated pathology were surgically removed under general anesthesia. After a three-month follow-up, the patient had an uneventful recovery.

Why is it important?

The rare and critical location of the reported wisdom tooth which is ectopically erupted in the maxillary sinus along with the infected dentigerous cyst is an interesting rare case where its complete enucleation is important to avoid complications as recurrence or malignant transformation.


This paper documented a rare case report which is very interesting to Oral radiologists and surgeons.

The importance of reporting this case comes from its rarity of the third molar location and its association with an infected dentigerous cyst, also being asymptomatic makes its early detection difficult. Early diagnosis and management is essential to minimize complications.
