Non-surgical therapy - Is there a better way to debride?

Hand instruments as well as well as sonic and ultrasonic scalers have been used over decades for subgingival debridement. They have proven their efficacy in removing bacterial deposits in numerous clinical, animal and in vitro studies. However, studies have also reported side effects of a frequent and long-term use of these instruments over many years in supportive periodontal therapy (SPT) i.e. damage to the root surface, gingival recession, discomfort or pain during treatment as well as tooth sensitivity after treatment, all factors potentially reducing patients' compliance attending regular SPT appointments. Therefore, new approaches have been investigated particularly for SPT to assess their capability in removing bacterial biofilm without causing the aforementioned side effects. One of the new approaches with increasing evidence is the so called "Air-Flow Therapy". The aim of this presentation is to provide an overview about devices, mechanisms of action, side effects and current scientific evidence of air-flow therapy in periodontal treatment.
