Which of the following statements is true regarding hypoparathyroidism and its impact on dental development?

HYPOPARATHYROIDISM causes LOW calcium levels (hypocalcemia). Calcium is essential for proper enamel formation. When hypoparathyroidism occurs during tooth development, it can cause ENAMEL HYPOPLASIA — defective/incomplete enamel formation. This is the classic dental manifestation. It does NOT increase caries resistance (B wrong — hypoplastic enamel is actually more susceptible). It doesn't cause larger teeth (C wrong). It definitely affects dental development (D wrong). A is correct.
