Which of the following lesions is known as a Pindborg tumor?Calcifying (epithelial) odontogenic tumor Adenomatoid odontogenic tumor AmeloblastomaSquamous odontogenic tumor Clear cell odontogenic carcinoma 3. The periodontal ligament anchors the tooth to the bone socket of the jaw and maxilla. Which of the following embryological elements is responsible for the formation of periodontal ligament?Mesenchymal cells outside the tooth AmeloblastsStellate reticulumNone of the answers are correctOdontoblasts 4. A 30 y/o patient is found to have a solid jaw lesion. Surgical excision is performed, and representative images are shown for review. Based on the findings, which of the following is the best diagnosis? Odontogenic Part 2, Case #4 Odontogenic Part 2, Case #4 Odontogenic Part 2, Case #4 Odontogenic Part 2, Case #4Ameloblastic Fibroma AmeloblastomaAmeloblastic CarcinomaMalignant AmeloblastomaFibrosarcoma 5. This lesion is characterized by a poorly differentiated conglomeration of dentin, cementum, and enamel. There are usually found in the first two decades of life. The best diagnosis is:Compound odontoma Ossifying fibroma Fibrous dysplasia Complex odontoma Ameloblastic odontoma 6. A unicystic ameloblastoma is characterized by all of the following EXCEPT:Infiltrating ameloblastic epithelial islands into the surrounding fibrous wall Palisaded basal cells with polarization of the nuclei Areas resembling stellate reticulum Vacuolization of the cytoplasm of the basal cells Single cyst lining 7. A 31 /o male had a destructive jaw lesion which was surgically removed. Representative images from the case are shown. Based on the findings, which of the following is the best diagnosis? Odontogenic Part 2, Case #1 Odontogenic Part 2, Case #1 Odontogenic Part 2, Case #1Malignant AmeloblastomaAmeloblastic CarcinomaSquamous cell carcinoma AdenocarcinomaAmeloblastoma 8. Which of the following embryologic elements is responsible for the formation of the enamel on the surface of the tooth?None of the answersOdontoblasts AmeloblastsStellate reticulum Mesenchymal cells outside the tooth 9. A 30 y/o patient is found to have a solid jaw lesion. Surgical excision is performed, and representative images are shown for review. Based on the findings, which of the following is the best diagnosis? Odontogenic Part 2, Case #6 Odontogenic Part 2, Case #6 Odontogenic Part 2, Case #6Calcifying Odontogenic Tumor (Pinborg tumor)Clear Cell Odontogenic Carcinoma Adenomatoid Odontogenic TumorAdenoameloblastomaRenal Cell Carcinoma 10. A 30 y/o patient is found to have a solid jaw lesion. Surgical excision is performed, and representative images are shown for review. Based on the findings, which of the following is the best diagnosis? Odontogenic Part 2, Case #5Ameloblastic Fibroma AmeloblastomaMalignant AmeloblastomaFibrosarcomaAmeloblastic Carcinoma 11. A 28 y/o female presents with a cystic jaw lesion. The cyst is curetted and representative images are shown. Based on the findings, which of the following is the best diagnosis? Odontogenic Part 2, Case #2 Odontogenic Part 2, Case #2 Odontogenic Part 2, Case #2Periapical Cyst Glandular Odontogenic CystOdontogenic Keratocyst Gorlin Cyst Radicular Cyst 12. Which of the following lesions is associated with McCune Albright Syndrome:Ameloblastic fibroma Ossifying fibroma Odontogenic fibroma Cementifying fibroma Fibrous dysplasia 13. This cystic lesion is characterized by a stratified squamous epithelium (at least partially), a well defined basal layer of cuboidal to columnar cells (may resemble ameloblasts), and ghost cells (similar to a pilomatricoma). The best answer is:Periapical cyst Odontogenic keratocyst Calcifying odontogenic cyst Dentigerous cyst Glandular odontogenic cyst 14. This lesion usually occurs in children or young adults, is often associated with trauma, and may be secondary to slow, minute, recurrent hemorrhages. The most likely diagnosis is:Juvenile ossifying fibromaPeriapical cyst Fibrous dysplasia Ameloblastic fibroma Giant cell granuloma 15. A 30 y/o patient is found to have a solid jaw lesion. Surgical excision is performed, and representative images are shown for review. Based on the findings, which of the following is the best diagnosis?
