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: 1
HbA prevents sickling in sickle cell trait patients because the presence of normal hemoglobin (HbA) reduces the proportion of HbS, preventing polymerization.

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.

Compound odontoma shows on a radiograph as
1) Supernumerary teeth
2) Radiolucent and radiopaque areas
3) Masses of calcified areas
4) Distinguishable tooth-like structures
Oral Pathology
Answer: 4
A compound odontoma is a benign odontogenic tumor consisting of enamel, dentin, cementum, and pulp arranged in recognizable tooth-like structures. Radiographically, it appears as multiple small, tooth-like radiopaque structures, unlike complex odontomas, which show as masses of calcified material.
