The epithelium which covers a healed ulcer is derived from
1. undifferentiated mesenchymal cells of the ulcer
2. intact epithelium at the ulcer margin
3. transformation of fibroblasts to epithelial cells
4. endothelial cells via the blood stream
Oral Pathology Answer: 2
The epithelium which covers a healed ulcer is derived from intact epithelium at the ulcer margin
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.
Bite cells are seen in -
1) G6PD deficiency
2) SCA
3) Hereditary spherocytosis
4) Trauma
                            General Pathology
                            Answer: 1
                            Bite cells are characteristic of G6PD deficiency, resulting from oxidative damage to red blood cells.
Trigeminal neuralgia 
 1. Does not disturb the patient during sleep
 2. Can be treated with NSAIDs
 3. Always bilateral in distribution
 4. Is a hereditary condition
                            Oral Pathology
                            Answer: 1
                            Trigeminal neuralgia does not disturb the patient during sleep.
Which of the following genetic conditions is MOST likely to be the cause of a child born with a small head, small eyes, six fingers on each hand, and congenital heart defects?
1) Trisomy 13
2) Trisomy 18
3) Trisomy 21
4) XXY
Trisomy 13 is associated with congenital anomalies such as a small head, small eyes, and congenital heart defects.
A patient exhibits radiolucent areas in the jaw bones which stimulate both periapical and periodontal lesions. The serum calcium is 13.5 mg% and serum phosphorus is 2.3 mg%. A biopsy from one of the radiolucent areas reveals a giant cell lesion. The most likely diagnosis is 
 1. Hyperparathyroidism
 2. Hypoparathyroidism
 3. Hultiple myeloma
 4. Muxoedema
                            Oral Pathology
                            Answer: 1
                            The most likely diagnosis for the patient is hyperparathyroidism, given the symptoms and lab findings.
What condition is typically characterized by a malar rash, arthritis, serositis, and the presence of antinuclear antibodies?
1) Goodpasture's syndrome
2) Friedreich ataxia
3) Huntington's disease
4) Systemic lupus erythematosus (SLE)
Systemic lupus erythematosus (SLE) is characterized by a malar rash, arthritis, serositis, and the presence of antinuclear antibodies.
