The odontoma which resembles anatomy of normal teeth is a
1) Composite odontoma
2) Compound odontoma
3) Complex odontoma
4) Complex compound odontoma
Oral Pathology
Answer: 2
Explanation: A compound odontoma is a type of odontogenic tumor that consists of multiple small tooth-like structures (denticles) and resembles the anatomy of normal teeth. In contrast, a complex odontoma has a more disorganized structure and does not resemble normal teeth.
An odontogenic neoplasm that may be mistaken for an ameloblastoma but is of mixed tissue origin and considerably less aggressive is
1) A cementoblastoma
2) An odontogenic fibroma
3) A cementifying fibroma
4) An ameloblastic fibroma
Oral Pathology
Answer: 4
An ameloblastic fibroma is a benign odontogenic tumor that contains both epithelial and mesenchymal components, making it a mixed tissue neoplasm. While it can resemble an ameloblastoma histologically, it is generally less aggressive and has a better prognosis. Ameloblastic fibromas are often found in younger patients and can be treated effectively with surgical excision.

Disadvantages of using a GRID during radiography is
1. Increased patient exposure
2. Decreased exposure time
3. Increased secondary radiation fog to film
4. Reduces secondary radiation to film
Oral Pathology
Answer: 1
Using a GRID during radiography increases patient exposure due to the need for higher doses.
