title: Models for assessing powered toothbrushes.
abstract: The continued development of the power toothbrush over the last 25 years has led to some present-day models that demonstrate increased efficacy in plaque removal compared with a manual brush. The wealth of clinical data that supports these claims has a reference to both in vitro and in vivo models. An overview of performance evidence compared with manual toothbrushes must also be considered from a research model view. The issue of power toothbrush safety in relation to soft tissue abrasion will offer an opportunity for the review of the scientific facts behind any fictitious "hype". Specific studies will provide clinical evidence on power toothbrush safety and performance. This paper will consider implications of the evidence for the use of powered toothbrushes in clinical practice and will emphasize the current consensus of clinical opinion in the light of scientific evidence.
