Hyperparathyroidism is a condition characterized by an overproduction of parathyroid hormone (PTH), which leads to increased bone resorption and changes in bone density. The radiographic features associated with hyperparathyroidism include:

• Loss of Lamina Dura: The lamina dura is the thin layer of dense bone that lines the tooth socket (alveolus). In hyperparathyroidism, the loss of lamina dura can be observed due to the increased osteoclastic activity and bone resorption.

• Ground Glass Appearance: This refers to a radiographic appearance of bone that looks hazy or "ground glass" rather than having a clear, well-defined structure. This appearance is due to the alteration in bone density and the presence of fibrous tissue replacing normal bone.

Other Options:

1. Osteogenesis Imperfecta: This condition is characterized by brittle bones due to a defect in collagen formation. Radiographically, it may show thin cortices and osteopenia, but not typically a ground glass appearance.

2. Osteopetrosis: This is a condition of excessive bone density due to impaired osteoclast function. Radiographically, it shows increased radiopacity (dense bones) rather than a ground glass appearance.

3. Osteitis Deformans (Paget's Disease): This condition is characterized by disorganized bone remodeling. Radiographically, it can show a "cotton wool" appearance and enlarged bones, but it does not typically present with a loss of lamina dura or a ground glass appearance in the early stages.

Pulsus paradoxus is an exaggerated decrease in systolic blood pressure during inspiration, which can occur in patients with airflow obstruction conditions such as emphysema and asthma. These conditions can lead to increased intrathoracic pressure swings during respiration, which affects the cardiac output and arterial pulse amplitude.

The newly formed collagen in the scar tissue is arranged differently compared to the organized collagen fibers in the unwounded skin, leading to a weaker structure. The 70-80% tensile strength is typically what is seen in well-healed sutured wounds. This remaining deficit is because scar tissue is less elastic and more prone to dehiscence (reopening) under tension compared to normal skin.

MEN II is characterized by the triad of medullary carcinoma of the thyroid, pheochromocytoma, and oral and intestinal ganglioneuromatosis.

Gingival group of fibers 
Principal fibers of the periodontal ligament rearranges themselves quite rapidly to the position in about 4 weeks.The supra-alveolar gingival fiber take as much as 40 weeks to rearrange around the new position and thus predispose to relapse.
