A 15-year-old female presents with a painless swelling in the anterior maxilla. Radiographic examination reveals a unilocular radiolucency surrounding the crown and part of the root of an unerupted maxillary canine. Small radiopaque flecks are seen within the lesion. What is the most likely diagnosis? Dentigerous cyst Adenomatoid odontogenic tumor (AOT) Ameloblastoma Odontogenic keratocyst (OKC) None 3. A 17-year-old female has an impacted maxillary canine with a pericoronal radiolucency. The dentist initially suspects a dentigerous cyst. However, histopathology reveals duct-like structures and eosinophilic droplets. What is the final diagnosis? Dentigerous cyst Ameloblastoma Adenomatoid odontogenic tumor (AOT) Calcifying odontogenic cyst None 4. A 14-year-old girl presents with a swelling in the anterior mandible. A radiograph shows a well-defined unilocular radiolucency around an erupted canine. Which variant of AOT is this? Follicular type Extra-follicular type Peripheral type Solid ameloblastoma None 5. A pathologist finds sheets of cuboidal and columnar tumor cells with whorled masses and duct-like structures. What additional feature on histology is most characteristic of AOT? Rushton bodies Ghost cells Tumor droplets Psammoma bodies None 6. A young female presents with a slow-growing, painless swelling in the anterior maxilla. The lesion is well-corticated and contains small radiopaque specks. What radiographic feature differentiates AOT from a dentigerous cyst?

The dentist diagnoses an odontogenic tumor but wants to rule out an aggressive lesion. Which of the following supports a diagnosis of AOT over ameloblastoma? AOT occurs in older adults AOT is aggressive and requires radical excision AOT is well-circumscribed and non-invasive AOT has high recurrence rates None 9. A surgeon excises an AOT from a patient’s maxilla. What is the recommended treatment to prevent recurrence? Radical resection Enucleation and curettage Chemotherapy Radiation therapy None 10. A radiologist is reviewing a case of AOT and notes small radiopaque flecks within the lesion. What causes these calcifications? Tumor droplets Dystrophic calcification Odontogenic keratin Cementum deposition None 11. A 13-year-old girl has a swelling in the anterior maxilla. A radiograph reveals a radiolucency around an impacted canine. The lesion is removed and confirmed as AOT. What is the prognosis? High recurrence rate Risk of malignant transformation Excellent prognosis with minimal recurrence Poor prognosis requiring aggressive treatment None 1 out of 6 Time's up
