Pathology

Chicken pox presents with multiple dermal lesions characteristically with vesicles, pustules which may secondarily ulcerate

Oral Medicine

Nystatin and clotrimazole work by binding to ergosterol in the fungal cell membrane, increasing permeability and allowing the leakage of intracellular components. This leads to the death of the affected fungal cell.

Prosthodontics

It establishes:

Relationship of teeth to the axis of rotation of the jaw → Ensures accurate occlusion simulation.

Relationship of maxilla to mandible → Helps in reproducing inter-arch relationships.

Relationship of mandible to cranium → Transfers the anatomical position of the jaws relative to the skull.

Thus, hinge axis face-bow records capture all of the above relationships to allow precise articulation and prosthodontic work.

The Morse sickle scaler is suited for the mandibular anterior interproximal area.

Pedodontics

Trauma from occlusion does not affect the gingiva and epithelial attachment.

Anatomy

Facial Artery:

1: True, it has cervical and facial portions.

2: True, it arises from the external carotid artery above the lingual artery.

3: True, it crosses the mandible at the anterior edge of the masseter muscle.

4: False, the cervical portion lies beneath the platysma, but the facial portion does not exactly lie "superficial in the carotid triangle"; rather, the facial artery travels more superficially than the cervical part in its course.

The text does not provide specifics on luting agent requirements in terms of compressive strength and setting time.

Prosthodontics

Explanation: Finalizing the RPD design before fixed prosthodontic treatment ensures that the RPD can be properly integrated with any existing or planned restorations, allowing for optimal function and aesthetics.

Pharmacology

Iodine-131 half-life ≈ 8 days.

After ~6 half-lives, >98–99% of the isotope is degraded.

8⋅6 = 48  days → closest option is 46 days.

This is clinically relevant because it determines radiation safety precautions and therapeutic monitoring in patients receiving I-131.

Oral Medicine

The most common cause of death in patients with pulmonary embolism is right ventricular failure. This occurs when the right ventricle of the heart is unable to pump blood effectively due to the sudden increase in pulmonary vascular resistance from the embolism.
