    Summary
    Objectives: The aim of this study was to evaluate the efficacy of four different powered toothbrushes with side-to-side action for noncontact biofilm removal in vitro. Materials and methods: A three-species biofilm was formed in vitro on protein-coated titanium disks using a flow chamber combined with a static biofilm growth model. Subsequently, the biofilm-coated substrates were exposed to four different side-to-side toothbrushes (A, B, C, and D) with various brushing times (2, 4, and 6s) and brushing (bristle-to-disk) distances (0, 2, and 4mm). The biofilm volumes were measured using volumetric analyses with confocal laser scanning microscope images and Imaris version 7.5.2 software. Results: The median percentages of biofilm reduction by the analyzed toothbrushes ranged from 9% to 80%. The abilities of the tested toothbrushes to remove the in vitro biofilm differed significantly (p < 0.05). Two of the tested toothbrushes (C and D) were capable of significant biofilm reduction by noncontact brushing. Conclusions: It was possible to reduce a three-species in vitro biofilm by noncontact brushing with two out of four side-to-side toothbrushes. Clinical relevance: Toothbrushes C and D show in vitro a high efficacy in biofilm removal without bristle contact.
