 # A patient has hypoplasia, microdontia, hypodontia, multiple unerupted teeth, numbness in oral cavity, peripheral paresthesia. This is most likely due to:

A. Hyperparathyroidism

B. Hypoparathyroidism

C. Hyperthyroidism

D. Hypothyroidism

The correct answer is:

B. Hypoparathyroidism

Explanation:
Hypoparathyroidism can cause a range of dental and neurological symptoms, including:

• Dental manifestations: Hypoplasia, microdontia, hypodontia, delayed eruption, and multiple unerupted teeth are associated with impaired calcium metabolism.
• Neurological symptoms: Numbness in the oral cavity and peripheral paresthesia occur due to hypocalcemia, which leads to increased neuromuscular excitability.

Other options explained:

• A. Hyperparathyroidism: May cause brown tumors, loss of lamina dura, and tooth mobility due to increased bone resorption, but not hypoplasia or unerupted teeth.
• C. Hyperthyroidism: Can lead to accelerated dental development but does not cause hypoplasia or hypodontia.
• D. Hypothyroidism: May cause delayed eruption and macroglossia but does not typically result in hypoplasia or paresthesia.
