Fig. 4From: In vitro comparison of cleaning efficacy and force of cylindric interdental brush versus an interdental rubber pickIllustration of a the experimental cleaning efficacy (ECE) and b the experimental cleaning force (ECF) for different sizes of IDR and IDB/IRP. Three different IDR on the x-scale (1.0 mm; 1.1 mm; 1.3 mm), the ECE on the y-scale, differing in IRP (blue), IDB ISO 1 (green), IDB ISO 2 dark red, IDB ISO 3 bright red and IDB ISO 4 in brownBack to article page
