Comparative Study
A comparative evaluation of the percent acceptable end-rounded bristles: Butler G.U.M., Colgate Plus, Crest Complete, and Reach.
Many researchers have concluded that end-rounded toothbrush bristles reduce the potential of soft tissue trauma. Toothbrushes with a rippled-bristle pattern have been shown to more effectively remove dental plaque from interproximal surfaces than flat-trimmed toothbrushes. Unfortunately, many attempts to utilize rippled-bristle toothbrushes are fraught with difficulty due to poor end-rounding of these bristles in the traditional manufacturing process. ⋯ U. M.) acceptable end-rounding was observed. These results demonstrate that the newly designed rippled-bristle brush (Crest Complete) exhibits excellent bristle end-rounding.
