An important factor for their prevention is the control of pathogenic microorganisms contained in bacterial biofilm deposited on dental surfaces. Gingivitis, periodontitis, and dental caries are the most frequent oral diseases. Conclusions: The U-shaped automatic electric toothbrush tested in this study proved to be not effective in removing dental plaque. The differences between treatments in clean mouth VAS was statistically significant ( p < 0.0001) favoring the P and H groups. On the contrary, the difference between the U and N groups was not significant (difference 5 95% CI from −2 to 12) favoring the U group. The differences were statistically significant between the U and P groups (difference −48 95% CI from −54 to −41) favoring the P group, and between the U and H groups (difference −45 95% CI from −52 to −39) favoring the H group.

The differences between treatments in FMPS reduction after brushing were statistically significant ( p < 0.0001). Results: Twenty-two participants were randomized to the treatments in the four periods of the study. Mixed models were performed for difference in FMPS and VAS. The secondary outcome variable was a visual analogic scale (VAS) on subjective clean mouth sensation. Primary outcome measure was the reduction in full-mouth plaque score (FMPS) after brushing. Methods: Eligible participants were volunteer students.

Background: The aim of this single-use, four-treatment, four-period (visit), cross-over, mono-centered, examiner-blind, cross-over randomized controlled trial (RCT) was to evaluate the efficacy in dental plaque removal of a U-shaped automatic electric toothbrush (U) compared to a conventional powered toothbrush (P), a habitual toothbrushing procedure (H), and no brushing (N).
