Clinical Trial Data on the Mechanical Removal of 14-Day-Old Dental Plaque Using Accelerated Micro-Droplets of Air and Water (Airfloss)

Novel strategies to combat dental biofilms aim at reducing biofilm stability with the ultimate goal of facilitating mechanical cleaning. To test biofilms, they need be subjected a defined stress. Here, we employed an oral care device (Airfloss) that emits microbursts compressed air and water apply shear 14-day-old plaque in 20 healthy participants no signs diseases (clinical trial no. NCT05082103). Exclusion criteria included pregnant or nursing women, users prostheses, retainers orthodontic appliances, recent antimicrobial anti-inflammatory therapy. Plaque accumulation, before after treatment, was assessed using fluorescence images disclosed on central incisor, first premolar, molar third quadrant (120 images). For each tooth, pre- post-treatment percentage index (PPI) Turesky modification Quigley-Hein (TM-QHPI) were recorded. The mean TM-QHPI significantly decreased treatment (p = 0.03; one-sample sign test), but significant difference between PPI observed 0.09; t-test). These data are value for researchers seek remove and/or disrupt biofilms.
