Are over contoured restorations worse for gingival health than under contoured restorations?

  1. True

  2. False

The correct answer is: True

Over contoured restorations can create an environment that is favorable for plaque accumulation due to the irregular contours which can trap food debris and plaque, leading to an increased risk of gingival inflammation and periodontal disease. On the other hand, under contoured restorations are easier to clean and maintain good oral hygiene, reducing the risk of gingival issues. Therefore, over contoured restorations are indeed worse for gingival health compared to under contoured restorations.
