Oral Pathology
Answer: 4
Koplik spots are first manifestation but seldom seen.
Koplik spots are small, white spots with a bluish-white color that appear on the
inside of the cheek opposite the molars in individuals with measles. They are
considered a pathognomonic sign of measles and typically appear 2-3 days before
the onset of the characteristic skin rash. However, they are not commonly
observed in all cases, making them a less frequently seen early manifestation of
the disease. They are small and can be easily overlooked or mistaken for other
oral conditions.

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.

Dens in dente is thought to arise as a result of
1. a normal tooth but enclaved within an other tooth, during formation
2. proliferation and evagination of an area of the inner enamel epithelium
3. extensive growth of mesenchymal cells of pulp tissue
4. an invagination of the enamel organ during tooth formation
Oral Pathology
Answer: 4
Dens in dente is a rare developmental dental anomaly that is characterized by a tooth with an invaginated or cavity-like structure that appears like a "tooth within a tooth." It arises from an error during the morphodifferentiation stage of tooth development.
