A bacterial disease with oral manifestations is
1) Herpes Measles
2) Measles
3) Diphtheria
4) Leishmaniasis
Oral Pathology
Answer: 3
Diphtheria serious bacterial infection that usually affects the mucous
membranes of the nose and throat.
Diphtheria signs and symptoms usually begin 2 to 5 days after a person becomes
infected. Signs and symptoms may include:
A thick, gray membrane covering the throat and tonsils
A sore throat and hoarseness
Swollen glands (enlarged lymph nodes) in the neck
Difficulty breathing or rapid breathing
Nasal discharge
Fever and chills
Tiredness
Skin (cutaneous) diphtheria
A second type of diphtheria can affect the skin, causing pain, redness and
swelling similar to other bacterial skin infections. Ulcers covered by a gray
membrane also may be a sign of skin diphtheria.

1. Rad
2. Rem
3. Roentgen
4. Quality factor
Oral Pathology
Answer: 2
Rem facilitates comparison between different types of radiation.
Adamantinoma is
1. A tumour from embryonal cell of developing teeth
2. Also known as ameloblastoma
3. Is a complication of dengigerous cyst
4. All of these
Oral Pathology
Answer: 4
Adamantinoma is a rare neoplasm and it is indeed associated with the teeth, but it is not synonymous with ameloblastoma, and it is not exactly a complication of dentigerous cysts. However, since all options are somewhat inaccurate or misleading, your answer indicates that you may be looking for the one best fitting choice.
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.
A patient exhibits radiolucent areas in the jaw bones which stimulate both periapical and periodontal lesions. The serum calcium is 13.5 mg% and serum phosphorus is 2.3 mg%. A biopsy from one of the radiolucent areas reveals a giant cell lesion. The most likely diagnosis is
1. Hyperparathyroidism
2. Hypoparathyroidism
3. Hultiple myeloma
4. Muxoedema
Oral Pathology
Answer: 1
The most likely diagnosis for the patient is hyperparathyroidism, given the symptoms and lab findings.
The residual biologic damage tha remains following an exposure to radiation is called
1. Direct effect
2. Indirect effect
3. Cumulative effect
4. Tolerance
Oral Pathology
Answer: 3
The residual biological damage that remains following exposure to radiation is called cumulative effect.
