ABSTRACT To evaluate the safety and plaque removal efficacy of an advanced rotating-oscillating power toothbrush relative to a sonic toothbrush with either a standard or compact brush head.
Two studies used a randomized, examiner-blind, two-treatment, crossover design. In Study 1, subjects were instructed to use their first randomly assigned toothbrush for five to seven days and then, after abstaining from all oral hygiene for 24 hours, were assessed with the Rustogi, et al. Modified Navy Plaque Index. They then brushed for two minutes and post-brushing plaque scores were recorded. Subjects were assigned to the alternate toothbrush and the procedures were repeated. In Study 2, subjects alternated using both brushes for approximately 10 days, then had four study visits three to four days apart (some variability based on patient scheduling). In Study 1, Oral-B Triumph with a FlossAction brush head and Sonicare Elite 7300 with a full-size, standard head were compared in a two-treatment, two-period crossover study. Study 2 compared Oral-B Triumph with a FlossAction brush head and Sonicare Elite 7300 with a compact head in a two-treatment, four-period crossover study.
Fifty subjects completed Study 1 and 48 completed Study 2. All brushes were found to be safe and significantly reduced plaque after a single brushing. In Study 1, Oral-B Triumph was statistically significantly (p < 0.001) more effective in plaque removal than Sonicare Elite 7300 with the full-size brush head: whole mouth = 24% better, marginal = 31% better, approximal = 21% better. In Study 2, Oral-B Triumph was statistically significantly (p < 0.001) more effective than Sonicare Elite 7300 with the compact brush head: whole mouth = 12.2% better, marginal = 14.6% better, approximal = 12% better.
Oral-B Triumph with its rotation-oscillation action was significantly more effective in single-use plaque removal than Sonicare Elite 7300 with its side-to-side sonic action when fitted with either a standard or a compact brush head.

    ABSTRACT: The aim of this study was to evaluate the plaque removal efficacy of four toothbrushes: the Philips Sonicare Elite with medium and mini brush heads, the Elmex Sensitive, and the American Dental Association (ADA) reference toothbrush. This study was a randomized, controlled, investigator-blinded, four-brush crossover design study, which examined plaque removal following a consecutive repeated use. All brushes were used on each participant in a randomly assigned quadrant of the mouth. A total of 90 subjects participated in the study. Prior to the experiment, they received a professional prophylaxis and were requested to refrain from toothbrushing for 48 h. Teeth were professionally brushed consecutively for 10 to 90 s per quadrant. A Turesky-modified Quigley Hein Index score was assessed at baseline and after each brushing interval by one blinded investigator. Results showed reduction of mean plaque scores for all brushes with time from 10 to 90 s. After 30 s (2-min whole mouth equivalent) of brushing, the Sonicare brushes cleaned 19, the ADA brush 16, and the Elmex Sensitive 10 of in average 28 tooth surfaces. With time, the number of additional cleaned surfaces decreased. Time is an important variable in the evaluation of plaque-removing efficacy since absolute efficacy increases with time and differs per toothbrush. No differences could be found between the two brush heads of the Sonicare.

    ABSTRACT: INTRODUCTION: Good oral hygiene is a challenge for orthodontic patients because food readily becomes trapped around the brackets and under the archwires, and appliances are an obstruction to mechanical brushing. The purpose of this study was to compare plaque removal efficacy of 3 toothbrush treatments in orthodontic subjects. METHODS: This was a replicate-use, single-brushing, 3-treatment, examiner-blind, randomized, 6-period crossover study with washout periods of approximately 24 hours between visits. Forty-six adolescent and young adult patients with fixed orthodontics from a university clinic in Germany were randomized, based on computer-generated randomization, to 1 of 3 treatments: (1) oscillating-rotating electric toothbrush with a specially designed orthodontic brush head (Oral-B Triumph, OD17; Procter & Gamble, Cincinnati, Ohio); (2) the same electric toothbrush handle with a regular brush head (EB25; Procter & Gamble); and (3) a regular manual toothbrush (American Dental Association, Chicago, Ill). The primary outcome was the plaque score change from baseline, which we determined using digital plaque image analysis. RESULTS: Forty-five subjects completed the study. The differences in mean plaque removal (95% confidence interval) between the electric toothbrush with an orthodontic brush head (6% [4.4%-7.6%]) or a regular brush head (3.8% [2.2%-5.3%]) and the manual toothbrush were significant (P <0.001). Plaque removal with the electric toothbrush with the orthodontic brush head was superior (2.2%; P = 0.007) to the regular brush head. No adverse events were seen. CONCLUSIONS: The electric toothbrush, with either brush head, demonstrated significantly greater plaque removal over the manual brush. The orthodontic brush head was superior to the regular head.

    ABSTRACT: A controlled, clinical, double blind study was conducted to assess the efficacy of a sugar-free chewing gum containing calcium hydroxyapatite on dentin hypersensitivity, versus a placebo chewing gum with no active ingredients, after one and two weeks.
