1. Rickets
2. Congenital hyperthyroidism

4. Cherubism
Oral Pathology
Answer: 2
Congenital hyperthyroidism does not typically cause delayed eruption of teeth.
In thalassemia the microscopic picture of RBCs is:
1. Microcytic, hypo chromic and target cells present
2. Macrocytic, hypochromic and target cell present
3. Microcytic. hypochromic and target cell absent
4. Macrocytic. hypochromic and target cells absent
Pathology
Answer: 1
Mcroscopic picture of red blood cells (RBCs) in thalassemia, the following
characteristics are typically observed:
Microcytic: The RBCs are smaller than normal (microcytic)
due to the reduced hemoglobin content.
Hypochromic: The RBCs have a lower concentration of
hemoglobin, leading to a paler appearance (hypochromic).
Target cells: These are RBCs that have a bullseye
appearance due to an abnormal distribution of hemoglobin within the cell.
Target cells are often seen in thalassemia due to the imbalance of globin
chains and the resultant membrane changes.
A wound which Was sutured attains:
1. Normal tensile strength after 6 months
2. 70-80% of tensile strength of unwounded skin which may persist for life
3. 100% tensile strength of unwounded skin after 9 months
4. 100% of tensile strength can be achieved if sutures were of nylon or vicryl
Pathology Answer: 2
The newly formed collagen in the scar tissue is arranged differently compared to the organized collagen fibers in the unwounded skin, leading to a weaker structure. The 70-80% tensile strength is typically what is seen in well-healed sutured wounds. This remaining deficit is because scar tissue is less elastic and more prone to dehiscence (reopening) under tension compared to normal skin.
