Acanthosis is
1. Increase in mitotic division
2. Increase in thickness of superficial layer
3. Increase in thickness of spinous layer
4. Disruption of basal lamina
Oral Pathology
Answer: 3
Acanthosis refers to the hyperplasia or
thickening of the stratum spinosum layer of the epidermis or epithelium. It is
often seen in conditions such as psoriasis or lichen planus. This is distinct
from other phenomena like increased mitotic division or disruption of the basal
lamina.

3. osteopetrosis
4. hypophosphatasia
Oral Pathology
Answer: 2
Palatal petechiae are often seen in infectious mononucleosis, which is caused by the Epstein-Barr virus.

Radiation injury to the haemopoietic system of the bone marrow occurs when the whole body exposure ranges between
1. 50-100 rads
2. 200-1000 rads
3. 1000-5000 rads
4. 10,000 rads to more
Radiation injury to the hematopoietic system occurs when whole body exposure ranges between 200-1000 rads.

The prothrombin levels that is of concern to dentist extraction is
1) 20 % normal PT
2) 40 % normal PT
3) 50 % normal PT
4) 100 % normal PT
Oral Pathology
Answer: 1
Prothrombin time (PT) is a measure of the blood's clotting ability. In dentistry, a PT level of 20% below normal is often considered a threshold for increased risk of bleeding during surgical procedures such as tooth extraction. At this level, the patient may be at risk for prolonged bleeding or hemorrhage. Dentists typically assess a patient's coagulation status before performing invasive procedures, especially if the patient has a known bleeding disorder or is on medications that affect clotting.
Penetration power of X-ray is measure of
1. Exposure time
2. Milliamperage
3. Kilovoltage
4. None of the above
Oral Pathology
Answer: 3
Penetration power of X-ray is primarily measured by kilovoltage.
