[Comparative study of the Interplak tooth cleansing instrument]

Unlike manual and electric toothbrushes, the brush head of the Interplak instruments remains stationary while ten tufts of bristle rotate. The efficacy of this new system was evaluated in comparison to a conventional electric toothbrush (Braun dental d3). When used for the first time the Interplak instrument proved to be more effective in reducing plaque. After training periods of 2 and 4 weeks there was, however, no significant difference between products.
