Correct answer: A — Thyroid hormone

Thyroid hormone (T3/T4) plays a critical role in tooth eruption and skeletal maturation. Hypothyroidism in children leads to delayed tooth eruption and skeletal development. While growth hormone, PTH, and other hormones influence skeletal growth, thyroid hormone has the most direct clinical correlation with the timing of tooth eruption.
