Which brushing technique places the bristles at the attached gingiva and sweeps them apically?

Modified Bass
Roll
Charter's
Stillman’s

The correct answer is: Roll

The brushing technique that places the bristles at the attached gingiva and sweeps them apically is known as the Roll technique. This technique is particularly effective for removing plaque and debris from the tooth surfaces and is especially beneficial for patients with gingival recession. In the Roll brushing method, the toothbrush is positioned so that the bristles are against the attached gingiva. The user then gently rolls the bristles downwards towards the apical direction, which aids in providing a gentle massaging effect on the gum tissue along with cleaning the teeth. This motion can help strengthen the gingival tissue as well as promote good oral hygiene by ensuring that plaque is effectively removed from both the teeth and the marginal gingival area. Other techniques like the Modified Bass, Charter's, and Stillman's have different positioning and motions that may focus on certain areas or aspects of oral hygiene, but they do not initiate the sweeping action from the attached gingiva or are utilized for different oral hygiene purposes. For instance, Modified Bass emphasizes a vibratory motion at the gum line and is typically recommended for effective plaque removal from sulcular areas.
