This is a report from the 11th European Workshop in Periodontology on primary prevention of periodontitis. The working group has focused on four different approaches: mechanical self-administered plaque control regimes, self-administered interdental mechanical plaque control, adjunctive chemical plaque control and anti-inflammatory approaches.A number of conclusions are drawn in this report. It is implied that professional oral hygiene instruction contributes to plaque and gingivitis reduction, and that reinforcement of the instruction may lead to enhanced results.
Concerning interdental brushes, they have shown the highest efficacy in plaque removal and are also shown to be the most accepted interdental cleaning devices among patients. Regarding the use of floss, most studies cannot show a general effectiveness in plaque removal or reduction of gingival inflammation. According to the working group, interdental brushes are the preferred choice for interdental cleaning. Floss can be an alternative only when sites are too narrow for the interdental brush and show gingival and periodontal health. It is stressed that any method chosen for interproximal cleaning should be preceded by professional instruction.
