1. Rickets
2. Congenital hyperthyroidism
3. Cleidocranial dysplasia

A White blood cell count of more than 1,00,000 cells/cc of blood indicates
1. Leukopenia
2. Leukocytosis
3. Leukaemia
4. Polycythaemia
Oral Pathology
Answer: 3
A white blood cell count of more than 100,000 cells/cc indicates leukemia.
The extracellular polysaccharide synthesized by cariogenic streptococci in the presence of excess sucros is best described as
1) Mucopolysaccharide
2) Dextran-like glucan
3) Glycogen-like glucan
4) Amylopectin
Oral Pathology
Answer: 2
Cariogenic streptococci, particularly Streptococcus mutans, synthesize extracellular polysaccharides when exposed to high levels of sucrose. These polysaccharides are primarily dextran-like glucans, which are formed from the polymerization of glucose units. Dextran contributes to the formation of dental plaque and biofilm, facilitating the adherence of bacteria to tooth surfaces and promoting caries development.
Diapedesis Connotes:
1. Pavementing of neutrophils
2. Migration of
neutrophils In tissues
3. Increased urine output
4. Exodus of neutrophils from
vascular compartment
Pathology Answer: 4
Diapedesis is a critical process in the body's immune response, particularly in the context of inflammation.
