Benefit of the power component of sonic and rotation-oscillation modes of action for plaque removal using power toothbrushes.

Purpose: To assess the benefit of the power component of two power toothbrushes, with sonic and rotation-oscillation mechanisms, on plaque removal efficacy.

Methods: Two independent studies with identical designs were used to assess the benefit of the power component of two power toothbrushes, with sonic and rotation-oscillation mechanisms, on plaque removal efficacy. Each brush was tested with the power 'On' relative to a control of the same brush with the power 'Off' used like a manual toothbrush.

Comparison of rotation/oscillation and sonic power toothbrushes on plaque and gingivitis for 10 weeks.

Purpose: Although power toothbrushes provide valuable tools toward improving oral health, contrasting results are discerned in their efficiency. This 10-week study was conducted to compare the safety and efficacy of rotation/oscillation and sonic power toothbrushes in the reduction of plaque and gingivitis.

Methods: This two-treatment, parallel group, examiner-blind, randomized study had the subjects brush twice daily at home with their assigned rotation/oscillation or sonic toothbrush following manufacturer's instructions with center visits at baseline, and at 4 and 10 weeks following the baseline visit, for assessment of oral safety (all visits), plaque (baseline, Weeks 4 and 10), and gingivitis (baseline and Week 10).

One- and 3-minute plaque removal by a battery-powered versus a manual toothbrush.

Background: A new battery-powered toothbrush with a fundamentally different design than other powered toothbrushes has recently been introduced. The new toothbrush has a powered oscillating round head and a second powered head that translates back and forth. This study compared the plaque removal efficacy of a manual toothbrush to this new powered toothbrush.

A plaque removal study comparing two advanced-design oscillating battery-powered toothbrushes.

Objective: The objective of this study was to compare the plaque removal efficacy of two advanced-design battery-powered toothbrushes (Crest SpinBrush Pro and Oral-B CrossAction Power) following a single use.

Methodology: This study was a randomized, controlled, examiner-blind, four-period crossover design, which examined plaque removal with the two toothbrushes following a single use by 40 subjects. Plaque was scored before and after brushing using the Turesky Modification of the Quigley-Hein Index.

Plaque removal efficacy of a prototype power toothbrush compared to a positive control manual toothbrush.

Purpose: Recently, a new experimental battery-powered toothbrush was developed as a second generation to Crest SpinBrush. The brush head of this new prototype toothbrush (Crest SpinBrush Pro) incorporates a dual moving head design with one oscillating and the other translating back and forth. The objective of this study was to compare the plaque removal efficacy of a positive control manual toothbrush (Oral-B Cross Action) to this prototype power toothbrush following a repeated single use study design.

Plaque removal efficacy of a new experimental battery-powered toothbrush relative to two advanced-design manual toothbrushes.

The current study was designed to assess the plaque removal efficacy of a novel experimental powered toothbrush (Crest SpinBrush Pro) compared to two leading manual toothbrushes, the Oral-B CrossAction and the Colgate Navigator. In addition, this paper reports the results of two additional studies examining the relative plaque removal efficacy of the two control manual toothbrushes and a number of other manual toothbrushes. The comparative study was a randomized, controlled, examiner-blind, nine-period crossover design, conducted among 127 adult subjects over a two-month period, that examined plaque removal with a new battery-powered toothbrush and two advanced-design manual toothbrushes.
