Radiolucent or Radiopaque: Periodontal ligament

Radiolucent
Radiopaque
Both Radiolucent and Radiopaque
None are correct

The correct answer is: Radiolucent

The periodontal ligament is a layer of soft tissue that attaches the tooth to the surrounding bone. This tissue is not very dense, so it appears less opaque (or less white) on a radiograph compared to other structures like bone, which appear more opaque. Therefore, the correct answer is A, radiolucent. Options B, C, and D are incorrect because they suggest that the tissue is either completely opaque (B), both transparent and opaque (C), or neither transparent nor opaque (D), which are all incorrect descriptions for the periodontal ligament.
