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). Methods: Eligible participants were volunteer students. Primary outcome measure was the reduction in full-mouth plaque score (FMPS) after brushing. The secondary outcome variable was a visual analogic scale (VAS) on subjective clean mouth sensation. Mixed models were performed for difference in FMPS and VAS. Results: Twenty-two participants were randomized to the treatments in the four periods of the study. The differences between treatments in FMPS reduction after brushing were statistically significant (p < 0.0001). 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. 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 between treatments in clean mouth VAS was statistically significant (p < 0.0001) favoring the P and H groups. Conclusions: The U-shaped automatic electric toothbrush tested in this study proved to be not effective in removing dental plaque.

Abstract Background: To evaluate the efficacy of a newly developed electric toothbrush in reducing dental plaque via a quantitative light-induced fluorescence-digital (QLF-D)-applied visualisation system in the brush head.Methods: Participants included 20 adults aged 19 to 28 years. Participants were randomly assigned either (i) an electric toothbrush with a monitor to visualise red-fluorescent dental plaque via a camera built into the brush head (monitor usage group, n = 10) or (ii) an electric toothbrush without a monitor (monitor-non-use group, n = 10). The amount of dental plaque was assessed by personal hygiene performance (PHP) at baseline and 1 week later.Results: In the monitor-usage group, PHP score was significantly lower at the 1-week follow-up than at baseline (6 vs 16; range, 0–12 vs 13–21; P = 0.029). This change was not observed in the monitor-non-use group (14 vs 13; range, 6-21 vs 2-26; P = 0.778). After 1 week, the change in PHP scores in the monitor usage group was significantly greater than that in the monitor non-use group (−10 vs 0; range, -21 to 9 vs -8 to 16; P = 0.021).Conclusions: Our results clearly demonstrate that brushing teeth while looking at a monitor that depicts red-autofluorescent dental plaque via application of QLF-D improved the efficacy of dental-plaque removal relative to brushing teeth without a monitor.

The aim of the present examiner-blind randomized controlled clinical study was to compare the efficacy two soft-bristle toothbrushes in terms of plaque removal. Seventy volunteers were randomly allocated to Group A (tapered-tip toothbrush) or Group B (end-rounded toothbrush). At baseline appointment (Day 0), volunteers underwent plaque examination using the Improved Plaque Identification Index. Under supervision, they brushed their teeth for 1 minute with their assigned toothbrushes and the plaque examination was repeated. Volunteers continued the oral hygiene regimen (assigned toothbrush and a regular dentifrice provided by the researchers) for 7 days. The experimental procedures of Day 0 were then repeated. Separate statistical analyses were performed for mean percent reduction of plaque in the whole-mouth, interproximal and gumline scores at both times, using Mann-Whitney test, p0.05). In conclusion, on Day 0, Group A presented higher efficacy in supragingival plaque removal than Group B, as reflected by whole-mouth, gumline and interproximal plaque scores.
