Illustration of the test devices for interdental cleaning (from the left): interdental brushes (IDB) with nylon with a wire core and nylon filaments with diameter of 0.8, 0.9, 1.2, 1.4 mm (ISO 1–4) and wireless interdental rubber picks (IRP) with finger-design (magnification showed in detail the different design of interdental brushes and rubber picks). The working part of the IRP is 16 mm with a taper of 0.05 of the core. The IDB shows no taper having a cylindrical shape, but a working part of 10 mm
