- Brief summaryThe efficacy in plaque removal on average following a single brushing exercise is only a reduction from baseline plaque scores of 42% (Slot et al. 2012). In populations that use toothbrushes, the interproximal surfaces of the molars and premolars are the predominant sites of residual plaque. Removal of plaque from these surfaces remains a valid objective because, in patients susceptible to periodontal disease, gingivitis and periodontitis are usually more pronounced in this interdental area than on oral or facial aspects (Löe 1979). Toothbrushing alone does not reach the interproximal areas of teeth, resulting in parts of the teeth that remain unclean. Good interdental oral hygiene requires a device that can penetrate between adjacent teeth. Interdental brushes are frequently recommended by dental professionals to patients with sufficient space between their teeth. Interdental brushes are small, specially designed brushes for cleaning between the teeth. Slot et al. (2008) systematically reviewed the literature to determine the effectiveness of interdental brushes used as adjuncts to toothbrushes in terms of the presence of plaque and clinical parameters of periodontal inflammation in patients with gingivitis or periodontitis. And concluded that as an adjunct to brushing, the IDB removes more dental plaque than brushing alone The Soft-Picks interdental cleaners resemble interedntal brushes, but do not have metal or nylon fiber bristles. Instead, they have small elastomeric fingers protruding perpendicularly from a plastic core. Till so far only one publication is available presenting a parallel design using this rubber interdental bristles cleaner and it was compared to an interdental brush. It concluded that regarding gingivitis reduction the interdental brush superior but for plaque reduction and removal both inderdental devices are comparably effective (Yost et al. 2006).
