Comparison of video and written instructions for plaque removal by an oscillating/rotating/reciprocating electric toothbrush

The purpose of this study was to compare the effectiveness of plaque control performed with electric and manual toothbrushes. Fifteen children with primary dentition and 14 children with mixed dentition were divided in two groups and randomly assigned to utilize a manual or an electric toothbrush. In the first session, professional plaque removal was performed, and the children spent 24 hours without brushing their teeth. In the second session, plaque was disclosed and assessed on all facial and lingual surfaces. After that, all children brushed their teeth with the predetermined toothbrush. The next procedure was the disclosure and measurement of residual plaque. After a period of 7 days, the children switched the kind of toothbrush, and the same procedures were repeated. According to the statistical analysis of the results, there were no significant differences concerning plaque removal when the toothbrushes were utilized by children with mixed dentition. On the other hand, the electric toothbrush promoted significantly greater plaque removal on the lingual surfaces of teeth from children with primary dentition.

ABSTRACT Objective: To compare the plaque removal efficacy of an oscillating-rotating electric toothbrush with an orthodontic brush head versus a sonic toothbrush in adolescent patients with fixed orthodontic appliances. Materials and Methods: This was a randomized, examiner-blind, replicate single-use, two-treatment, four-period, crossover study with a washout period between visits of approximately 24 hours. Forty-four adolescent patients with fixed orthodontic appliances in both arches were randomized based on a computer-generated randomization schedule to one of four toothbrush treatment sequences. The primary outcome was plaque score change from baseline, measured using digital plaque imaging analysis. Results: Baseline plaque levels for both brush treatments were high, covering more than 50% of the tooth area. Effective plaque removal was observed with both brush treatments (P < .001); however, the reduction in plaque with the oscillating-rotating toothbrush was statistically significantly greater (P = .017) compared with the sonic toothbrush. Conclusions: The study provides evidence for more effective plaque-removing efficacy of the oscillating-rotating toothbrush versus the sonic toothbrush among orthodontic patients.

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.
