Radiology

Cephalometric radiographs require low contrast and wide latitude films to visualize both soft tissues and hard tissues simultaneously. Wide latitude allows for better visualization of structures with different densities in the same image, which is essential for cephalometric analysis.

Christ-Siemens-Touraine Syndrome is a form of hypohidrotic ectodermal dysplasia, characterized by hypohidrosis (reduced sweating), hypotrichosis (sparse hair), and oligodontia (few teeth). Supernumerary teeth are extra teeth and are not characteristic; rather, missing teeth are expected.

Supracrestal fibrotomy (also known as circumferential supracrestal fibrotomy or CSF) is a surgical procedure performed to sever the supracrestal fibers around a tooth, which helps prevent relapse of corrected rotations, especially in the maxillary canine region, as these fibers are primarily responsible for the rotational memory of the tooth and subsequent relapse.

Vascular dementia is considered an irreversible form of dementia because it is caused by damage to blood vessels in the brain, often resulting from strokes or chronic reduced blood flow. The brain tissue that dies as a result of this damage cannot be regenerated. While treatments can manage symptoms and prevent further damage, the existing damage and associated cognitive decline cannot be reversed.

 

  • Subarachnoid hemorrhage can cause acute cognitive issues, but these are often treatable and potentially reversible, not inherently a cause of irreversible dementia in the long term.
  • Wilson's disease is a genetic disorder that causes copper to accumulate in the body, including the brain. The resulting neurological and psychiatric symptoms, including dementia, are treatable and largely reversible with timely diagnosis and appropriate therapy.
  • Normal pressure hydrocephalus is a condition where excess cerebrospinal fluid accumulates in the brain's ventricles. The symptoms, including dementia, can often be significantly improved or reversed with surgical shunting.
