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. METHODS: This randomized, controlled, examiner-masked, four-period cross-over study examined plaque removal with the two toothbrushes following a single use in 40 subjects. Plaque was scored before brushing and after 1 and 3 minutes of brushing using the Turesky modification of the Quigley-Hein index. RESULTS: Baseline plaque scores were 2.98 prior to using the powered toothbrush and 2.99 prior to using the manual toothbrush. The powered toothbrush delivered a covariance-adjusted mean plaque score change from baseline of 0.61 after 1 minute of brushing and 0.93 after 3 minutes of brushing. The adjusted mean changes for the manual toothbrush were 0.43 and 0.62, respectively. The differences between treatment groups were statistically significant (P < 0.001) after both 1 and 3 minutes of brushing. The powered toothbrush had, on average, 42.1% and 49.6% greater plaque removal scores after 1 minute and 3 minutes of brushing, respectively. Both toothbrushes had statistically significantly greater plaque removal scores after 3 minutes than after 1 minute of brushing (P < 0.001). Plaque removal scores for each toothbrush after 3 minutes of brushing were about 50% higher than the scores after 1 minute of brushing. CONCLUSIONS: The powered toothbrush delivered statistically significantly superior plaque removal after both 1 and 3 minutes of brushing compared to the manual toothbrush. Both toothbrushes showed statistically significantly greater plaque removal following 3 minutes of brushing than following 1 minute of brushing, and the difference between the toothbrushes was greater following 3 minutes of brushing than following 1 minute of brushing.

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. In addition, this paper reports the results of a study examining the relative plaque removal efficacy of the positive control manual toothbrush to seven representative manual toothbrushes. METHODS: This study was a randomized, controlled, examiner-blind, four-period crossover design, which examined plaque removal with the two toothbrushes following a single use in 40 subjects. Plaque was scored before and after brushing using the Turesky Modification of the Quigley-Hein Index. RESULTS: Baseline plaque scores were 2.61 and 2.66 for the prototype power toothbrush and control toothbrush treatment groups, respectively. With respect to all surfaces examined, the prototype power toothbrush delivered an adjusted (via analysis of covariance) mean difference between baseline and post-brushing plaque scores of 0.98 while the control toothbrush delivered an adjusted mean difference of 0.74. The experimental toothbrush group, on average, had a 32.8% larger plaque removal score than the control toothbrush. These results were statistically significant (P < 0.001). Similar results were observed on buccal and lingual surfaces. In addition, results from the study comparing manual toothbrushes showed that the positive control manual toothbrush had higher plaque removal scores compared to seven representative manual toothbrushes. The plaque removal score differences reached statistical significance for five of the seven toothbrushes.

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. RESULTS: Average baseline plaque scores were 2.915 and 2.883 for the SpinBrush Pro and CrossAction Power toothbrush treatments, respectively. The SpinBrush Pro toothbrush delivered an adjusted (via analysis of covariance) mean difference between baseline and post-brushing plaque scores of 0.802, while the CrossAction Power toothbrush delivered an adjusted mean difference of 0.667. The SpinBrush Pro toothbrush, on average, had 20.2% greater plaque removal scores relative to the CrossAction Power toothbrush. These results were statistically significant (p < 0.001). The observed results on the buccal and lingual surfaces were consistent with the overall results, and were statistically significant. CONCLUSION: The results of this study support the conclusion that the SpinBrush Pro removes statistically significantly greater amounts of plaque over a one-minute brushing period compared to the CrossAction Power toothbrush.

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. During the course of this study, subjects brushed three times with the experimental powered toothbrush and three times with each control manual toothbrush. Study participation was on a voluntary basis following written informed consent of the subjects. Plaque was scored before and after brushing using the Turesky, et al. Modification of the Quigley-Hein Index. Average baseline plaque scores were 2.68 to 2.69 for the three treatment groups. The experimental toothbrush delivered an adjusted (via analysis of covariance) mean difference between baseline and post-brushing plaque scores (i.e., a plaque removal score) of 0.69, while the control toothbrushes delivered adjusted mean differences of 0.46 (Colgate Navigator) and 0.54 (Oral-B CrossAction). All group differences were statistically significant (p < 0.001). The experimental powered toothbrush group had, on average, 49% and 28% greater plaque removal scores than the Colgate Navigator and Oral-B CrossAction groups, respectively. In addition, the Oral-B CrossAction group had, on average, a 16% greater plaque removal score than the Colgate Navigator group. This result was also statistically significant (p < 0.001). Results on buccal and lingual surfaces also demonstrated statistically significantly (p < 0.001) greater plaque removal for the experimental battery-powered toothbrush relative to the control manual toothbrushes.
