What is an example of occlusal trauma as a risk factor?

An example of occlusal trauma as a risk factor is parafunctional habits such as clenching or bruxism. These habits involve abnormal tooth contact and excessive force on the teeth and supporting structures during non-functional movements. This increased mechanical stress can lead to various periodontal issues, including the breakdown of the supporting tissues around teeth, as well as exacerbating existing conditions like periodontal disease.

In contrast, excessive dental plaque accumulation relates more to microbial factors leading to inflammation and periodontal disease, rather than mechanical forces. The use of antimicrobial mouthwash deals with controlling the bacterial load rather than mechanical trauma. Similarly, improper flossing techniques may lead to trauma in some cases but are generally more associated with plaque control and not classified specifically as occlusal trauma. Hence, parafunctional habits are the primary example of occlusal trauma affecting periodontal health.
