Abstract
Introduction: Biofilms may show varying adherence strengths to dentine. This study quantified the shear force required for the detachment of multispecies biofilm from the dentine using fluid dynamic gauging (FDG) and computation fluid dynamics (CFD). To date this force has not been quantified. Methods: Multispecies biofilms were grown over 3, 7 and 14 days on 2 mm thick dentine sections of human molars (n = 8 per group). The FDG technique with different suction flow rates (100%, 80% and 40%) was used to assess biofilm removal. At maximum suction (100%), the flow rate was 500 mL/min. Digital images of each stained dentine sample were captured (10× magnification) before and after subjecting the samples to the various suction flow rates.
