A novel biofilm removal approach (Guided Biofilm Therapy) utilizing erythritol air-polishing and ultrasonic piezo instrumentation: A randomized controlled trial.

Biofilm removal using erythritol AIRFLOW® and ultrasonic piezo-electric instruments (GBT) can be considered equally efficient compared with the conventional SRP. Moreover, GBT seemed to require shorter treatment time and to exhibit a more favourable patient perception than the conventional approach.
