In which scenario would the root debridement stroke be utilized?

The root debridement stroke is specifically designed for removing biofilm, calculus, and debris from the root surfaces, especially in cases where the cementum or dentin is exposed due to gingival recession. In this scenario, the objective is to thoroughly clean the compromised root surfaces to promote healing and reduce the risk of periodontal disease. The technique generally involves a gentle yet firm stroke that helps to ensure all irregularities and deposits are effectively addressed.

In contrast, the other situations presented do not necessitate the specific characteristics of a root debridement stroke. Removing plaque from a healthy tooth relies more on standard brushing or scaling techniques that don't require the specialized approach of root debridement. Cleaning instruments after procedures involves sterilization and hygiene practices rather than strokes on tooth structures. Lastly, assessing tooth surface conditions typically requires visual inspection or probing rather than the mechanical action of root debridement, which is targeted at the hard-to-reach areas of root surfaces.
