Trigeminal neuralgia ( tic doulourex ) is characterized by
1. Paralysis of one side of the face
2. Uncontrollable twitching of muscles
3. Sharp, excruciating pain of short duration
4. Prolonged episodes of pain on one side of the face
Oral Pathology
Answer: 3
Trigeminal neuralgia is a chronic pain
condition involving the trigeminal nerve, which supplies sensation to the face.
The hallmark symptom is sudden, severe, stabbing or electric-shock-like pain,
typically lasting for seconds to a few minutes. This pain is often triggered by
stimuli such as touching the face, chewing, or even speaking. Other options
(e.g., paralysis or prolonged episodes) do not describe this condition
accurately.
The X-rays which are mostly likely to be absorbed by the tissues and produce an injury
1. X-rays of long wavelength
2. X-rays of short wavelength
3. Filtered X-rays
4. Central rays
Oral Pathology
Answer: 1
X-rays of long wavelength are more likely to be absorbed by tissues and cause injury.
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.
The Maximum penetration among the following is seen with which ray
1. Alpha
2. Beta
3. Gamma
4. Electron beam
Oral Pathology
Answer: 3
Gamma rays have the maximum penetration among the listed types of radiation.
Apoptosis is suggestive of?
1. liquifaction degeneration
2 coagulation necrosis
3 neo angiogenesis
4 eithelial dysplasia
Pathology
Answer: 2
Cells die by one of two mechanisms – necrosis or
apoptosis
• Two physiologically different processes
– Necrosis – death by injury
– Apoptosis – death by suicide
Appoptosis:
Disintegration of cells into membrane-bound particles that are then eliminated by phagocytosis or by shedding.
Heterozygous sickle cell anemia gives protection against -
1) G6PD
2) Malaria
3) Thalassemia
4) Dengue fever
General Pathology
Answer: 2
Heterozygous sickle cell anemia provides protection against malaria due to the altered red blood cell environment that is less hospitable to the malaria parasite.
Crew haircut appearance in X-ray skull and Gamna Gandy bodies are seen in -
1) G-6-PD deficiency
2) Hodgkin's lymphoma
3) Hereditary spherocytosis
4) Sickle cell anaemia
General Pathology
Answer: 4
Crew haircut appearance in X-ray skull and Gamna Gandy bodies are associated with sickle cell anemia due to chronic hemolysis and bone marrow hyperplasia.
What is a common symptom of low serum calcium levels?
1) Hypertension
2) Tetany
3) Hyperphosphatemia
4) Anemia
Tetany is a common symptom of low serum calcium levels, characterized by muscle cramps and spasms due to increased neuromuscular excitability.
