Gingival stimulation has been shown to increase keratinization on gingival surfaces and to remove plaque biofilm.The effects on improving periodontal health are related to both actions.

Question

Quizplus · Accepted Answer

The first statement is true, as gingival stimulation can promote keratinization on the gingival surface, which can help to prevent gingival recession and reduce the risk of gum disease. However, the second statement is false, as gingival stimulation alone cannot effectively remove plaque biofilm. Plaque biofilm can only be removed through mechanical techniques such as brushing and flossing. Therefore, the effects of gingival stimulation on periodontal health are limited to promoting gingival health and preventing gingival recession, rather than removing plaque biofilm.
