• B. Down's syndrome
• C. Teacher collin syndrome
• D. Gorlin Goltz syndrome

Explanation: Maroteaux-Lamy syndrome, or mucopolysaccharidosis type VI, is associated with multiple unerupted teeth and bilateral dentigerous cysts.

• A. Periapical cyst
• B. Dentigerous cyst
• C. Globulomaxillary cyst
• D. Nasopalatine cyst

Explanation: Among the listed cysts, a dentigerous cyst can become large and locally destructive, especially when associated with an impacted tooth.

• A. Enucleation
• B. Enbloc resection
• C. Segmental resection with 1 cm of normal bone
• D. Enucleation with cauterizationOral & Dental Care

Explanation: Solid or multicystic ameloblastoma commonly requires resection because simple enucleation has a high recurrence rate.

• A. Primordial cyst
• B. Dentigerous cyst
• C. Mucocele
• D. Radicular cyst

Explanation: The radicular cyst is the most common odontogenic cyst and develops at the apex of a non-vital tooth from inflammatory stimulation of…

• A. Glandular odontogenic cystOral & Dental Care
• B. Paradental cyst
• C. Eruption cyst
• D. Radicular cyst

Explanation: A glandular odontogenic cyst is believed to arise from remnants of the dental lamina or other odontogenic epithelial remnants.

• A. Polyhedral epithelial cells
• B. Tubular / duct like cells
• C. Stellate shaped cells
• D. Stratified squamous epithelial cells

Explanation: Adenomatoid odontogenic tumour characteristically contains epithelial cells arranged in duct-like or rosette-like structures, often with…

• A. Surgical Excision

• D. Reassure the patient without any treatment

Explanation: A blue-dome swelling over an erupting tooth in a child is typical of an eruption cyst.

• A. Basal layer of cells
• B. Stratum intermedium
• C. Stratum corneum

• E. Both B & D

Explanation: Pindborg tumour, or calcifying epithelial odontogenic tumour, is thought to arise from remnants of the dental lamina and may show…

• A. Odontogenic keratocyst
• B. Calcifying epithelial odontogenic tumor (CEOT)
• C. Ameloblastoma
• D. None of the above

Explanation: A radiolucency containing radiopaque flecks is characteristic of a calcifying epithelial odontogenic tumour, where the flecks represent…

• A. Odontogenic keratocyst
• B. Jawcyst basal cell Nevus Syndrome
• C. Cherubism
• D. thyroid disorders

Explanation: Gorlin-Goltz syndrome, also called nevoid basal cell carcinoma syndrome, is associated with multiple odontogenic keratocysts that may…

• A. Impacted 3rd molar
• B. Impacted supernumerary tooth
• C. All of the above
• D. Odontome

Explanation: A dentigerous cyst develops around the crown of an unerupted tooth and may be associated with impacted third molars, supernumerary teeth…

• A. Surgical removal followed by cauterization
• B. Excision
• C. Enucleation
• D. Irradiation

Explanation: Ameloblastoma is locally aggressive and has a high recurrence rate after simple enucleation, so treatment requires surgical removal with a…

• A. Aneurysmal bone cyst
• B. Memorrhagic bone cyst
• C. Static bone cavity
• D. Ameloblastoma

Explanation: A hollow jaw cavity without an epithelial lining is typical of a traumatic or haemorrhagic bone cyst, which is a pseudocyst rather than a…

• A. 2-3 mm
• B. 3-4 mm
• C. >5 mm
• D. 1-2 mm

Explanation: A follicular space around an unerupted tooth that exceeds about 5 mm is suspicious for a dentigerous cyst rather than a normal dental…

• A. Mixed tissue of dental origin with no resemblance to tooth structure
• B. All of the above
• C. Haphazardly arranged calcified mass
• D. Numerous tooth like structure with denticles commonly found in maxillary lateral incisors

Explanation: A compound odontoma is made up of multiple small, recognisable tooth-like structures called denticles and commonly occurs in the anterior…

• A. Ameloblastoma
• B. Fibroma
• C. Papilloma
• D. None of the above

Explanation: Ameloblastoma is a locally destructive odontogenic tumour that infiltrates bone, although metastasis is very uncommon.

• A. condensing osteitis
• B. cementoma
• C. Periapical abscess
• D. None of the above

Explanation: Periapical cemental dysplasia, traditionally included under cementoma, occurs around the apices of vital teeth.

• A. Resection of jaw
• B. Pulpectomy
• C. No treatment
• D. None of the above

Explanation: Periapical cemental dysplasia usually needs no treatment because it is self-limiting and does not require removal; periodic observation is…

• A. Aspiration Cytology
• B. Excision biopsy
• C. CT Scan
• D. Pet Bone scan

Explanation: Aspiration is the safest next step for a large multilocular radiolucency because it can identify blood, pus or cystic fluid and help…

• A. Amebloblastic fibroodontoma
• B. All of the above
• C. Compound odontoma
• D. Calcifying odontogenic cyst

Explanation: Ghost cells are most characteristic of the calcifying odontogenic cyst, but they may also occur in odontogenic lesions containing…
