Content of the webinar Gingivitis, periodontitis and caries are widespread diseases with a microbial etiology. A prerequisite for therapeutic success is the mechanical destruction, ideally the removal, of infectious pathogenic biofilms. While the subgingival biofilm is addressed by dental professionals using suitable methods, the continuous management of supragingival biofilms is the responsibility of the patient. Today, there is a wide range of tools available for daily plaque removal. In this presentation, the effectiveness and the underlying scientific evidence of the respective products will be examined and appropriate recommendations for the individual patient's oral hygiene instruction will be given.
