tooth brushing behavior
PLAQUE

Instruction to brush teeth to the best of one’s ability results in a greater effort compared to brushing as usual. In particular, it leads to changes in the quantitative aspects of brushing (longer duration, more interdental hygiene) but not in the qualitative aspects, such as paying attention to the inner surfaces, cleaning the gingival margins or using dental floss appropriately. However, the increase in effort goes along with an increase in self-perceived oral cleanliness, which is not verified by objective plaque assessment. Emphasizing the qualitative aspects of tooth brushing behavior and raising awareness of hygiene deficits could be a first step toward improving the effectiveness of oral hygiene.
