Trial Summary

What is the purpose of this trial?

The goal of this randomized, masked-examiner clinical trial is to investigate a full-mouth electronic toothbrush (FMET). The three arms are: 1) FMET + American Dental Association (ADA) approved dentifrice, 2) conventional electronic toothbrush (ETB) + ADA dentifrice and 3) FMET + foam system.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but if you are on medications that affect periodontal conditions, like phenytoin or steroids, you may not be eligible to participate.

What data supports the effectiveness of the treatment Full-mouth Electronic Toothbrush for dental health?

Research shows that electric toothbrushes, especially those with oscillating-rotating actions and novel brush heads, are more effective than manual toothbrushes in reducing plaque and gingivitis (gum inflammation). This suggests that the Full-mouth Electronic Toothbrush could be effective in improving dental health by reducing plaque and gingivitis. ^{1 2 3 4 5}

Is the electronic toothbrush safe for use in humans?

Research shows that electronic toothbrushes, like the Braun Oral-B and Crest SpinBrush, are generally safe for use in humans, with mild side effects such as gum irritation being the most common. These side effects are similar to those experienced with manual toothbrushes. ^{6 7 8 9 10}

How does the Full-mouth Electronic Toothbrush treatment differ from other treatments for dental health?

The Full-mouth Electronic Toothbrush treatment is unique because it uses oscillating-rotating technology with micro-vibrations, which has been shown to significantly improve oral hygiene by reducing plaque and improving gum health more effectively than manual toothbrushes. ^{1 2 3 11 12}

Baseline and 30-day outcome measures will be collected to evaluate the impact of FMET + foam on clinical indicators of gingivitis, plaque, and patient perceptions.

Group II: FMET + ADA dentifrice Experimental Treatment 1 Intervention

Baseline and 30-day outcome measures will be collected to evaluate the impact of FMET + ADA dentifrice on clinical indicators of gingivitis, plaque, and patient perceptions.

Findings from Research

In a study involving 35 healthy participants, the Braun Oral-B 3D Plaque Remover electric toothbrush significantly reduced gingivitis and bleeding on probing compared to a manual toothbrush after 4 weeks of use.

The electric toothbrush also demonstrated superior plaque removal effectiveness, and participants preferred it over the manual toothbrush, indicating it may encourage longer brushing sessions.

In a 12-week study involving 100 adults with gingivitis and plaque, the oscillating-rotating (O-R) electric toothbrush significantly improved gingival health, with 86% of users achieving a 'healthy' status compared to only 20% of manual toothbrush users.

The O-R toothbrush also led to a greater reduction in bleeding sites and plaque across all regions, demonstrating its superior efficacy in improving oral health compared to a manual toothbrush.

In a study of 110 adults with gingivitis, the novel oscillating-rotating electric toothbrush (Oral-B iO) significantly reduced gingivitis and plaque compared to a manual toothbrush, with benefits observed as early as one week and continuing through the eight-week trial.

After eight weeks, 82% of participants using the O-R toothbrush were classified as 'healthy' (less than 10% bleeding sites), compared to only 24% of those using the manual brush, highlighting the O-R toothbrush's superior efficacy in improving gum health.

The new sonic powered toothbrush demonstrated significant reductions in supragingival plaque and gingivitis severity after just one use and continued effectiveness over 12 weeks, outperforming a manual toothbrush.

After four and 12 weeks, the sonic toothbrush showed up to 90 times greater reductions in plaque and significant improvements in gingival health compared to the manual toothbrush, indicating its superior efficacy in maintaining oral hygiene.

In a study comparing an oscillating/rotating power toothbrush (Oral-B Precision Clean) to a manual toothbrush, the power toothbrush demonstrated significantly greater plaque removal, achieving 28.8% reduction for the whole mouth, 44.3% along the gingival margin, and 20.7% on approximal surfaces.

Both toothbrushes were effective in reducing plaque, but the power toothbrush outperformed the manual toothbrush with statistically significant results (p < 0.001), indicating its superior efficacy in maintaining oral hygiene.

In a 3-month study involving 114 participants, the Braun Oral-B 3D electric toothbrush significantly outperformed a standard manual toothbrush in reducing plaque and gingivitis, with reductions of 15% and 16% respectively, compared to 8% and 12% for the manual toothbrush.

Both toothbrushes were safe to use, showing no clinically significant tissue abrasion, but the 3D electric toothbrush demonstrated greater efficacy in plaque reduction across all evaluated time points.

In a study of 104 participants over 4 weeks, all three toothbrushes (Crest Spin Brush, Colgate ActiBrush, and Oral B 40) were found to be generally safe, with only mild adverse events reported, primarily localized gingivitis.

The Crest Spin Brush and Colgate ActiBrush were better tolerated than the Oral B 40, suggesting that electric toothbrushes can be as safe as manual ones for daily use.

In a study involving 140 participants over four weeks, the Crest SpinBrush Pro powered toothbrush was found to be at least as safe as two leading manual toothbrushes, with no significant differences in adverse events reported among the groups.

The most common adverse event was mild localized irritation of the gums, with only one severe case of tooth sensitivity, indicating that while some irritation occurred, it was generally mild and manageable.
