• B. Enbloc resection
• C. Segmental resection with 1 cm of normal bone

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

• B. 3-4 mm
• C. >5 mm
• D. 1-2 mm

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.

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

• A. Resection of jaw
• B. Pulpectomy
• C. No treatment

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
