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.

Precancerous potential in Plummer-Vinson syndrome may be due to change in the epithelium like
1. Atrophy
2. Hypertrophy
3. Acanthosia
4. All the above
Oral Pathology
Answer: 1
Plummer-Vinson syndrome is associated with atrophic changes in the
epithelium, which can lead to an increased risk of cancer
Plummer-Vinson syndrome is characterized by a classic triad of
clinical features: dysphagia (difficulty swallowing), iron-deficiency anemia,
and esophageal webs. Additional symptoms may include glossitis (inflammation of
the tongue), koilonychia (spoon-shaped nails), and cheilitis (inflammation of
the lips).
Clinical Features of Plummer-Vinson Syndrome:
Dysphagia:
Difficulty swallowing due to the presence of esophageal webs, which
can obstruct the esophagus.
Iron-Deficiency Anemia:
Resulting from chronic blood loss or malabsorption, leading to
fatigue and weakness.
Esophageal Webs:
Thin membranes that form in the esophagus, contributing to
swallowing difficulties.
Glossitis:
Inflammation of the tongue, which may appear smooth and swollen.
Koilonychia:
Spoon-shaped nails that can indicate iron deficiency.
Cheilitis:
Inflammation and cracking of the lips, often associated with
nutritional deficiencies.
Fatigue and Weakness:
Common symptoms due to anemia and nutritional deficiencies.
Associated Risks:
Esophageal Cancer:
There is an increased risk of developing esophageal cancer in
individuals with Plummer-Vinson syndrome.
Prevention:
Iron Intake:
Ensuring adequate dietary iron may help prevent the onset of this
syndrome. Diagnosis and Management:
Diagnosis:
Diagnosis is typically made through clinical evaluation, endoscopy,
and imaging studies to identify esophageal webs and assess for anemia.
Management:
Treatment often involves iron supplementation to address anemia and
dietary modifications to improve iron intake. In some cases, dilation of
esophageal webs may be necessary to alleviate dysphagia
Ramsay Hunt syndrome affects which nerve

Commonest site for carcinoma of tongue is
1) Lateral margin
2) Tip of tongue
3) Posterior 1/3
4) Ventral surface
Oral Pathology
Answer: 1
The commonest site for carcinoma of the tongue is the lateral margin.
Carcinoma of the tongue is the most frequent oral cancer, and it typically
arises from the squamous cells that cover the surface of the tongue. The lateral
margin of the tongue is the part of the tongue that lies next to the teeth and
the gingivae. This site is often exposed to various carcinogens, such as those
found in tobacco and alcohol, which can increase the risk of developing cancer.

1. Mercury
2. Zinc
3. Lead
4. Bismuth
Oral Pathology
Answer: 2
