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.
Thistle-tube appearance of pulp chamber is a feature of
1) Coronal dentin dysplasia
2) Regional odontodysplasia
3) Dentinogenesis imperfecta
4) Amelogenesis imperfecta
Oral Pathology
Answer: 1
Coronal dentin dysplasia is a genetic condition that affects the development of dentin, leading to abnormal pulp chamber morphology. The "thistle-tube" appearance refers to the shape of the pulp chamber, which resembles a thistle tube due to the constricted and elongated form of the pulp space. This condition is characterized by a normal crown appearance but with significant alterations in the pulp chamber and root canal system, making it distinct from other dental dysplasias.
When treated with simple curettage which odontogenic tumour is most likely to recur
1) Complex odontoma
2) Compound odonotoma
3) Odentogenic myxoma
4) Ameloblastic fibroma
Oral Pathology
Answer: 3
Explanation: Odontogenic myxoma is known for its aggressive behavior and tendency to recur after treatment, including curettage. It is a benign but locally invasive tumor, and simple curettage often does not remove the entire tumor, leading to recurrence.
