Silver tattoo is due to
1. Deposition of Ag amalgam in mucosa
2. Deposition of Ag amalgam in bone
3. Deposition of Ag amalgam in dentin
4. Deposition of Ag amalgam in enamel
Oral Pathology
Answer: 1
Silver tattoo is due to the deposition of Ag amalgam in the mucosa.
Sickle cell trait patient do not have manifestations as that of Sickle cell disease, because-
1) 50% HbS is required for occurrence of sickling
2) HbA prevents sickling
3) 50% sickles
4) HbA prevents polymerization of Hbs
General Pathology
Answer: 2
HbA prevents sickling in sickle cell trait patients because the presence of normal hemoglobin (HbA) reduces the proportion of HbS, preventing polymerization.
What of the following is characterized by left lower quadrant periumbilical pain in an elderly person, with the presence of fever, tender abdomen, leukocytosis, nausea, and vomiting?
1) Acute appendicitis
2) Diverticulitis
3) Gallstones
4) Pancreatitis
General Pathology Answer: 2
Diverticulitis is characterized by left lower quadrant pain, fever, and leukocytosis, especially in elderly patients.
In thalassemia the microscopic picture of RBCs is:
1. Microcytic, hypo chromic and target cells present
2. Macrocytic, hypochromic and target cell present
3. Microcytic. hypochromic and target cell absent
4. Macrocytic. hypochromic and target cells absent
Pathology
Answer: 1
Mcroscopic picture of red blood cells (RBCs) in thalassemia, the following
characteristics are typically observed:
Microcytic: The RBCs are smaller than normal (microcytic)
due to the reduced hemoglobin content.
Hypochromic: The RBCs have a lower concentration of
hemoglobin, leading to a paler appearance (hypochromic).
Target cells: These are RBCs that have a bullseye
appearance due to an abnormal distribution of hemoglobin within the cell.
Target cells are often seen in thalassemia due to the imbalance of globin
chains and the resultant membrane changes.
In sickle cell trait, number of bands found in Hb-
1) 2
2) 1
3) 4
4) 5
General Pathology
Answer: 1
In sickle cell trait, the number of bands found in hemoglobin is typically 2, representing both HbA and HbS.
Premature exfoliation of deciduous teeth is seen in
1. Hypophosphatasia
2. Hypophosphataemia
3. Hyperphosphtasia
4. Hyperparathyrroidism
Oral Pathology
Answer: 1
Premature exfoliation of deciduous teeth is seen in hypophosphatasia.
The peripheral blood smear of a patient shows features of thalassemia, also presented with anemia. Family history is also +ve. The investigation was done to establish the diagnosis is -
1) ESR estimation
2) Blood spherocyte estimation
3) Bone marrow aspiration
4) Hb-electrophoresis
General Pathology
Answer: 4
Hb-electrophoresis is the investigation done to establish the diagnosis of thalassemia, as it separates different hemoglobin types based on their charge.

3. Mucopolysaccharide metabolism
4. Carbohydrate metabolism
Oral Pathology
Answer: 2
Letterer-Siwe disease is a disturbance of lipid metabolism.
