AeroDam is a device that attaches to the dental turbine on one side and to the suction hose connector on the other. Its perimeter design with respect to the turbine head allows maximum proximity to the source of the aerosols without leaving exposed flanks. AeroDam captures the aerosol flow emitted by the turbine, that has been deflected onto the tooth surface or surfaces opposing that flow (dental mirror surface or inside the oral cavity, when the flow direction is not perpendicular to the tooth surface). The proximity of the surface in opposition to the direct flow favours the efficiency of the system. The device is designed so that the airflow forms a dam with a toroidal vortex structure within which the aerosol is confined.
