Which hormone participates in tooth eruption?
Show answer and explanation
Correct answer: D. Thyroxine
- A. Incorrect – PTH regulates serum calcium/phosphate and bone remodeling broadly, but it is not the hormone classically tied to tooth-eruption timing.
- B. Incorrect. Insulin is not a recognized driver of tooth eruption; thyroxine deficiency (hypothyroidism) is the hormone classically linked to delayed eruption.
- C. Incorrect. Calcitonin lowers serum calcium and inhibits osteoclasts; it is not the hormone tied to the eruption mechanism.
- D. Correct – thyroid hormone (T3/T4) directly influences eruption timing: hypothyroidism causes DELAYED eruption, hyperthyroidism ACCELERATES it. This is the classic eruption-related hormone.
