Question

Increased tooth mobility and the absence of lamina

dura are signs of
A. hyperthyroidism.
B. hyperpituitarism.
C. hyperparathyroidism.
D. scleroderma.

Answer 1

Increased tooth mobility and the absence of laminadura are indicative of hyperparathyroidism, a condition associated with excessive calcium reabsorption from the bones.

Step-by-step explanation:

Increased tooth mobility and the absence of laminadura are signs of hyperparathyroidism. This condition is characterized by an overproduction of parathyroid hormone (PTH), which leads to excessive calcium reabsorption from bone, significantly decreasing bone density and potentially leading to spontaneous fractures or deformities. Hyperparathyroidism can cause high serum calcium, low serum phosphate, bone destruction, and kidney stones, and it can result in manifestations in dental health such as increased tooth mobility due to the weakening of the jawbone.
