Trauma from occlusion affects blood supply to gingiva. True or False?

  1. True

  2. False

The correct answer is: True

Trauma from occlusion can occur when there is excessive force being applied to the teeth or when the teeth don't come together properly. This can lead to damage to the periodontal ligament and surrounding tissues, affecting the blood supply to the gingiva. Therefore, the statement is true. False is incorrect because occlusal trauma can indeed affect the blood supply to the gingiva and cause damage to the surrounding tissues.
