Comparative efficacy of a new battery-powered toothbrush and a commercially available manual toothbrush on the removal of established supragingival plaque: a single-use crossover study in adults.

OBJECTIVE: The objective of this single-use, examiner-blind, two-treatment crossover clinical study was to evaluate the efficacy of a new battery-powered toothbrush (Colgate MicroSonic) relative to that of a currently marketed manual toothbrush (Oral-B Indicator) for the removal of supragingival plaque. This study included the assessment of plaque removal in the whole mouth, at the gumline, and at interproximal sites via the comparison of pre- and post-brushing plaque levels measured using the Rustogi Modification of the Modified Navy Plaque Index. METHODOLOGY: Qualifying adult male and female subjects from the Newark, New Jersey area were provided with a commercially available toothbrush (Colgate Plus Toothbrush) and dentifrice (Colgate Cavity Protection Great Regular Flavor Fluoride Toothpaste) to use at home for three days before beginning the first phase of the crossover study. Subjects returned to the study site after refraining from any oral hygiene procedures for twenty-four hours, and from eating, drinking, or smoking for four hours. Following an examination for supragingival plaque (pre-brushing), they were stratified, based on their plaque scores, into two balanced groups, each of which used the two study toothbrushes in the order specified by a pre-determined randomization plan. Subjects were instructed to brush their teeth for one minute under supervision with their first assigned toothbrush and the commercially available toothpaste provided, after which they were again evaluated for supragingival plaque (post-brushing). Subjects were then dismissed from the study site, and instructed to use the home-use toothbrush and dentifrice. After three days, subjects returned to the study site for the second phase of the crossover study. Pre- and post-brushing evaluations were again performed following the same procedure, with each of the two subject groups now using the second toothbrush in the assigned treatment order. RESULTS: Of the forty-two (42) subjects entered into the study, thirty-nine (39) complied with the protocol and completed the clinical study. The results of the study indicate that the Colgate MicroSonic battery-powered toothbrush provided a statistically significant reduction in pre- to post-brushing plaque index scores of up to 52.9%. Relative to the manual toothbrush, the Colgate MicroSonic battery-powered toothbrush provided a statistically significant greater reduction in supragingival plaque scores of up to 200%. CONCLUSION: The results of this study support the conclusion that the new Colgate MicroSonic battery-powered toothbrush provides a clinically acceptable level of efficacy for the removal of supragingival plaque. Further, the Colgate MicroSonic battery-powered toothbrush exhibited significantly greater levels of efficacy for the removal of supragingival plaque when compared to the Oral-B Indicator Toothbrush.

Plaque removal efficacy of a new experimental battery-powered toothbrush relative to two advanced-design manual toothbrushes.

The current study was designed to assess the plaque removal efficacy of a novel experimental powered toothbrush (Crest SpinBrush Pro) compared to two leading manual toothbrushes, the Oral-B CrossAction and the Colgate Navigator. In addition, this paper reports the results of two additional studies examining the relative plaque removal efficacy of the two control manual toothbrushes and a number of other manual toothbrushes. The comparative study was a randomized, controlled, examiner-blind, nine-period crossover design, conducted among 127 adult subjects over a two-month period, that examined plaque removal with a new battery-powered toothbrush and two advanced-design manual toothbrushes. During the course of this study, subjects brushed three times with the experimental powered toothbrush and three times with each control manual toothbrush. Study participation was on a voluntary basis following written informed consent of the subjects. Plaque was scored before and after brushing using the Turesky, et al. Modification of the Quigley-Hein Index. Average baseline plaque scores were 2.68 to 2.69 for the three treatment groups. The experimental toothbrush delivered an adjusted (via analysis of covariance) mean difference between baseline and post-brushing plaque scores (i.e., a plaque removal score) of 0.69, while the control toothbrushes delivered adjusted mean differences of 0.46 (Colgate Navigator) and 0.54 (Oral-B CrossAction). All group differences were statistically significant (p < 0.001). The experimental powered toothbrush group had, on average, 49% and 28% greater plaque removal scores than the Colgate Navigator and Oral-B CrossAction groups, respectively. In addition, the Oral-B CrossAction group had, on average, a 16% greater plaque removal score than the Colgate Navigator group. This result was also statistically significant (p < 0.001). Results on buccal and lingual surfaces also demonstrated statistically significantly (p < 0.001) greater plaque removal for the experimental battery-powered toothbrush relative to the control manual toothbrushes.

Relative extrinsic stain removal effectiveness of a new battery-powered toothbrush and a flat trim manual toothbrush.

PURPOSE: To evaluate the stain removal efficacy of two different toothbrush designs using a laboratory stained pellicle test with seven different dentifrices. METHODS: The toothbrushes were a prototype powered toothbrush (Crest SpinBrush Pro Whitening) and an ADA reference manual toothbrush, as a control. The dentifrices used in the study were: Crest Dual Action Whitening (Cool Mint), Crest Extra Whitening with Tartar Control (Clean Mint), Crest MultiCare Whitening (Fresh Mint), Colgate Total, Colgate Total Plus Whitening, Arm & Hammer Advance White with Tartar Control and Rembrandt Plus with Active Dental Peroxide. This was a randomized, parallel group study that examined stain removal with a novel toothbrushing configuration adapted for powered and manual toothbrushes. Stain was scored before and after brushing for two consecutive, 1-minute periods using digital image analysis. The mean change in L* was statistically compared between toothbrushes with ANCOVA. Labial enamel specimens were obtained from bovine permanent incisors and these specimens were subjected to a laboratory staining process until the L* values for the samples were in the range of 35-45. Digital images for CIE L*a*b* analysis were captured using a high-resolution digital camera under standard polarized lighting conditions. Based on the L* values, the enamel specimens were divided into 14 groups of nine specimens each. RESULTS: Baseline L* values ranged from 40.62 to 41.38 for the 14 toothbrush/dentifrice combinations. The change in L* (post-brushing minus baseline), denoted as deltaL*, was calculated for each specimen and the resulting data were subjected to a two-way ANCOVA. Toothbrush type and dentifrice type were the two terms in the model, and baseline L* was the covariate. Pairwise tests were performed on the adjusted means in order to compare the stain removal efficacy of the two toothbrushes for each of the seven dentifrices evaluated. The powered toothbrush resulted in statistically significantly greater deltaL* values (all P < or = 0.006) than the manual toothbrush for every dentifrice tested. The deltaL* values for dentifrices used with the powered toothbrush were from 66.0-164.2% higher than for the same dentifrice used with the manual toothbrush.

Effectiveness of a battery-powered toothbrush on plaque removal: comparison with four manual toothbrushes.

The objective of these four clinical studies was to evaluate the efficacy of the Colgate Actibrush battery-powered toothbrush in comparison with four top-selling manual European toothbrushes (Dr. Best Flex Toothbrush [Germany]; Reach Triple Action Ultra Clean Toothbrush [Germany]; Jordan Multi-Action Toothbrush [Norway]; and Sanogyl Systeme In'Side Double Action Toothbrush [France]) for plaque removal. Each clinical study used a single-use, examiner-blind design in which the Colgate Actibrush battery-powered toothbrush was compared with one of the 4 manual toothbrushes for removal of plaque in adult subjects after 24 hours of no oral hygiene. Supragingival plaque formation was assessed prebrushing and after a 1-minute supervised brushing with either the battery-powered toothbrush or 1 of the manual toothbrushes. After 24 hours of no oral hygiene, Colgate Actibrush removed statistically significantly more plaque than did all 4 of the manual toothbrushes. The results of these clinical studies support the conclusion that Colgate Actibrush is clinically superior for the control of supragingival plaque, compared with the leading selling European manual toothbrushes.

Safety and plaque removal efficacy of a battery-operated power toothbrush and a manual toothbrush.

PURPOSE: To compare the safety and plaque removal efficacy of a battery-operated power toothbrush and a reference adult manual toothbrush. MATERIALS AND METHODS: This was a single-blind, randomized, split-mouth study. The power toothbrush studied was the Braun Oral-B Battery toothbrush (D4) and this was compared with a standard reference ADA manual toothbrush. The D4 toothbrush is derived from the Plaque Remover range of toothbrushes and has an oscillating/rotating action. At an initial visit, subjects (n = 48) were given a baseline examination of the oral hard and soft tissues and were instructed in the use of the D4. After one week during which subjects used the D4 at home, they returned to the test facility having abstained from oral hygiene for 23-25 hours. Two contralateral quadrants of the mouth were then randomly assigned to be cleaned with each toothbrush. Plaque assessments and hard and soft tissue examinations were made before and after brushing each quadrant for 15 seconds. Plaque was evaluated using the Rustogi modification of the Navy Plaque Index. RESULTS: Plaque levels were significantly reduced for all sites, marginal sites and approximal sites by both toothbrushes (P < 0.0001), but the efficacy of the D4 was significantly greater than that of the ADA manual brush for all comparisons (P < 0.0001). The greatest difference between the two toothbrushes was at approximal sites where the D4 removed 19% more plaque than the manual toothbrush. For all sites, the D4 was 14% more effective, while at marginal sites the difference in favor of the D4 was 12%.

Comparison of gingivitis and plaque efficacy of a battery-powered toothbrush and an ADA-provided manual toothbrush.

This examiner-blind clinical study evaluated the efficacy of a new battery-powered toothbrush with oscillating head (Colgate Actibrush) on established gingivitis and plaque at 15 days and again at 30 days, as compared to a control manual toothbrush (American Dental Association [ADA]-provided toothbrush, full head, soft bristles). A total of 63 participants completed the study. They were stratified into two balanced groups according to their mean baseline prebrushing plaque scores and were randomly assigned to use the battery-powered test toothbrush or the manual control toothbrush. Participants were instructed to brush their teeth twice daily (mornings and evenings) for 1 minute with their assigned toothbrush for the 30-day duration of the study. Gingivitis and plaque (pre- and postbrushing) examinations were conducted by the same dental examiner at baseline, after 15 days, and again after 30 days. The Colgate Actibrush demonstrated a significantly greater reduction of plaque (46.53%) and gingivitis (18.57%) when compared to the ADA-provided toothbrush after 30 days of use. Additionally, a comparison of the plaque scores for the battery-powered toothbrush at 15 and 30 days shows a continued reduction in plaque of more than 25% for a cumulative difference from baseline of 73%. These results support the conclusion that the new battery-powered toothbrush is clinically superior in plaque removal efficacy and gingivitis efficacy to the manual toothbrush, and continues to significantly improve plaque scores even up to 30 days of use.

Comparative efficacy of the Colgate Actibrush battery-powered toothbrush vs Oral-B CrossAction toothbrush on established plaque and gingivitis: a 6-week clinical study.

The objective of this clinical program was to compare the efficacy of the Colgate Actibrush battery-powered toothbrush and the Oral-B CrossAction Toothbrush (full head, soft bristle) for the control of supragingival plaque and gingivitis. Two independent clinical studies were conducted: Study 1 (repeated 3 times) was a single-use, examiner-blind clinical study designed to measure the removal of plaque after 24 hours of no oral hygiene. Study 2 was a definitive 6-week, examiner-blind clinical study designed to determine plaque and gingivitis efficacy at 3 and 6 weeks. Sixty-one men and women, who had refrained from using oral hygiene procedures for 24 hours, were entered into the study and stratified into 2 balanced groups according to baseline (prebrushing) plaque and gingivitis scores. For Study 1, Modified Navy Plaque Index (Rustogi Refinement) scores were obtained prebrushing and after a 1-minute supervised brushing with the assigned toothbrush and a commercially available toothpaste. On 3 separate occasions, after 24 hours of no oral hygiene, the Colgate Actibrush battery-powered toothbrush removed significantly more plaque than did the CrossAction Toothbrush. For Study 2, subjects were instructed to brush their teeth twice daily for 1 minute with the assigned toothbrush. Plaque Index scores and Löe-Silness Gingival Index scores were assessed after 3 and 6 weeks. At the 6-week examination, the group using the Colgate Actibrush battery-powered toothbrush exhibited a statistically significant reduction in both supragingival plaque and gingivitis, compared with the group that used the CrossAction Toothbrush. The results of these clinical studies support the conclusion that the Colgate Actibrush battery-powered toothbrush is clinically superior for the control of both supragingival plaque and gingivitis, as compared with the Oral-B CrossAction manual toothbrush.

Comparison of the safety and efficacy of an oscillating/rotating battery-powered toothbrush and a standard manual toothbrush.

PURPOSE: To compare the cleaning efficacy of a battery-powered toothbrush with an oscillating/rotating action (Dr. Best Powerclean) and a standard flat-trimmed manual toothbrush (Elmex super 39) in a single-blind, cross-over clinical study. MATERIALS AND METHODS: 78 healthy subjects took part in the study. Subjects were asked to abstain from all oral hygiene procedures for 48 hours, after which hard and soft oral tissues were examined. Plaque was then scored using the Turesky modification of the Quigley-Hein Index, and subjects were instructed to brush their teeth for a total time of 1 minute with either one or the other brush, according to a predetermined randomization schedule. Immediately after brushing, plaque was scored again and hard and soft tissues were re-examined. All plaque scoring was carried out by the same investigator who was blind with respect to the brushes used. Subjects were instructed to continue with their usual oral care routine throughout the study period. They were scheduled to return after 12-14 days, having again abstained from all oral hygiene for 48 hours prior to the visit, in order to repeat the evaluation sequence but brushing with the alternative brush. Prior to analysis of the results, data from the two phases of the study were combined. RESULTS: Both toothbrushes were found to be safe as used in the study. Using the non-parametric Wilcoxon test for paired samples, whole mouth plaque scores were found to be reduced significantly from 2.04 +/- 0.60 to 1.57 +/- 0.51 by the Powerclean toothbrush (P < 0.001), and from 1.99 +/- 0.65 to 1.27 +/- 0.52 by the manual toothbrush (P < 0.001). At approximal surfaces, the plaque scores were also significantly reduced from 2.14 +/- 0.0.59 to 1.69 +/- 0.50 for the Powerclean (P < 0.001), and from 2.08 +/- 0.64 to 1.40 +/- 0.57 for the manual toothbrush (P < 0.001). A comparison of the two brushes revealed that the manual toothbrush removed significantly more plaque than the Powerclean, both for the whole mouth and approximal surfaces (P < 0.001). The Powerclean reduced whole mouth plaque by 23.2 +/- 11.5% compared to 37.8 +/- 14.0% for the manual toothbrush and approximal plaque by 20.9 +/- 10.6% and 34.9 +/- 14.0%, respectively. It is concluded that the Dr. Best Powerclean toothbrush is not as effective as a standard flat-trimmed manual toothbrush.

A split-mouth comparison of a three-dimensional-action electric toothbrush and a high-frequency electric toothbrush for reducing plaque and gingivitis.

PURPOSE: To compare the effectiveness in reducing plaque and gingivitis of an electric toothbrush with three-dimensional (oscillating/rotating/pulsating) brush head action, Braun Oral-B 3D Plaque Remover, and an electric toothbrush with high-frequency vibrating action, Sonicare Plus. MATERIALS AND METHODS: This was a randomised, split-mouth study of 33 adult subjects who used both electric toothbrushes for a total of 9 weeks. After a 2-week acclimation period of brushing with each device on alternating days, subjects received a prophylaxis, then refrained from any oral hygiene on the mandibular teeth for 21 days to induce gingivitis. However, they continued to brush the maxillary teeth on alternating days with each electric toothbrush. Then, for a period of 4 weeks they brushed each side of the mouth with different toothbrushes, randomly assigned to right or left. Plaque and gingivitis were assessed initially, after the 21-day no-oral-hygiene period, and after 2, 3 and 4 weeks of brushing twice daily. RESULTS: After 21 days without oral hygiene, mean mandibular plaque and gingivitis scores increased significantly for all subjects. Use of both electric toothbrushes during the treatment phase progressively reduced plaque and gingivitis scores at each successive examination. The Braun toothbrush was significantly more effective than the Sonicare toothbrush in reducing plaque at every examination and gingival bleeding after 4 weeks of brushing. It is concluded that the Braun electric toothbrush with three-dimensional brush head action offers advantages over the Sonicare electric toothbrush with high-frequency vibrating action in terms of plaque control and potential improvement of gingival health following induction of experimental gingivitis.

Comparison of plaque removal efficacy of a battery-powered toothbrush and a manual toothbrush: a single-use clinical study in New Jersey.

OBJECTIVE: This single-use, examiner-blind clinical study evaluated the efficacy of a newly introduced battery-powered toothbrush (Colgate Motion Toothbrush) relative to a manual toothbrush (Oral-B CrossAction toothbrush) for the removal of supragingival plaque. METHODOLOGY: This study assessed plaque removal via the comparison of pre- and post-brushing plaque levels. A total of 126 adult male and female subjects from the northern New Jersey area reported to the clinical facility for a baseline (pre-brushing) plaque examination after having refrained from all oral hygiene procedures and chewing gum for 24 hours, and from eating, drinking or smoking for four hours. Subjects were entered into the study and stratified into two balanced groups based on their baseline plaque scores. Subjects were instructed to brush their teeth for one minute under supervision with their assigned toothbrush and a commercially available dentifrice, after which they were once again evaluated for supragingival plaque (post-brushing). RESULTS: All 126 subjects completed all aspects of the single-use clinical study. The subjects who used the Colgate Motion toothbrush exhibited a statistically significant 42.1% greater plaque reduction after a single tooth brushing than did those subjects who used the Oral-B CrossAction toothbrush. Relative to the pre-brushing baseline scores, the Colgate Motion toothbrush group exhibited a statistically significant 59.0% reduction in plaque removal. CONCLUSION: The results of this single-use, examiner-blind, clinical study support the conclusion that the battery-powered Colgate Motion toothbrush provides significantly greater efficacy for the removal of supragingival plaque than does the manual Oral-B Cross-Action toothbrush.

Comparison of the laboratory interproximal access efficacy of the Colgate precision toothbrush and the Crest complete toothbrush.

The Colgate Precision toothbrush was compared to the Crest Complete toothbrush for interproximal access efficacy using a laboratory device designed to simulate clinical toothbrushing motions and weights. Each vertical and horizontal brushing motion was timed for one minute for each of the three brushing weights tested; 250, 500 or 750g. Pressure-sensitive paper was placed around all simulated tooth surfaces to record the brushing strokes. The measurements of the recorded brushing strokes provided the interproximal access efficacy of all brushes. A total of twenty-four Colgate Precision toothbrushes and twenty-four Crest Complete toothbrushes were tested for both brushing motions, both tooth shapes and all three brushing weights, resulting in a total of 576 measurements. With vertical brushing motion using both tooth shapes tested and at all brushing weights, the Colgate Precision toothbrush had significantly greater interproximal access efficacy (p < 0.01 by ANOVA) than the Crest Complete toothbrush. With horizontal brushing motion on both tooth shapes tested, at the 500 and 750g brushing weights, the Colgate Precision toothbrush had significantly higher interproximal access efficacy (p < 0.01 by ANOVA) than the Crest Complete toothbrush. When total interproximal access efficacy means (comparing results of all weights tested) were evaluated, the Colgate Precision toothbrush was superior (p < 0.01) to the Crest Complete product for both brushing motions and tooth shapes tested.

A review of the clinical efficacy of the Oral-B oscillating/rotating power toothbrush and the Philips Sonicare toothbrush in normal subject populations.

Plaque removal by a toothbrush results from a physical scrubbing of bristles on the tooth surface that removes adherent plaque bacteria. Because of the frequency of brush head motion, some power toothbrushes generally remove plaque more effectively than a manual brush. One power toothbrush, Philips Sonicare, claims also to remove plaque as a result of dynamic fluid activity. This effect has been shown in laboratory studies but clinical evidence is currently lacking. This review evaluated the data from well-controlled clinical studies carried out in normal subjects from a general population comparing the Sonicare toothbrushes with the Oral-B oscillating/rotating power toothbrush technology. It focuses on plaque removal from approximal surfaces where it is difficult for toothbrush bristles to reach, as it is here that any dynamic fluid effect should be most apparent. Results from the review found no evidence to support a greater efficacy for the Sonicare toothbrushes either generally or at approximal surfaces. Data revealed that the oscillating/rotating toothbrush was more effective than the Sonicare toothbrushes with respect to plaque removal. It is possible that factors associated with the clinical situation such as damping resulting from bristle contact with the tooth surface and the high viscosity of saliva and dentifrice may counteract dynamic fluid activity in vivo. This review indicates that dynamic fluid activity beyond the reach of bristles as demonstrated in the laboratory is yet unproven in the clinical situation.

A single-use and 3-month clinical investigation of the comparative efficacy of a battery-operated power toothbrush and a manual toothbrush.

PURPOSE: To compare the safety and efficacy of a manual toothbrush and a battery-operated power toothbrush in two separate studies, one utilizing a single-use design and the other a 3-month parallel-group design. MATERIALS AND METHODS: The toothbrushes compared in the two studies were the Oral-B CrossAction manual toothbrush and the Colgate Actibrush battery-operated power toothbrush. The single-use study, which used a single-blind, cross-over design, involved 71 healthy subjects, who were instructed to abstain from oral hygiene for 23-25 hours prior to brushing with each of the two toothbrushes. Plaque was measured using the Proximal Marginal Index (PMI) pre- and post-brushing. The 3-month parallel-group study involved a total of 113 subjects who had plaque (PMI), gingivitis and bleeding (Loe and Silness) scored at baseline and after 1 and 3 months of product use. RESULTS: In both studies, the two toothbrushes were found to be safe. In the single-use study, significantly greater amounts of plaque were removed by the CrossAction manual toothbrush than by the Actibrush for the whole mouth as well as for marginal and approximal sites (P < 0.001). In the 3-month study, significantly greater plaque reduction was achieved with the CrossAction brush, the advantage being significant at 1 month for all sites except lingual sites (P < 0.05). At 3 months, there were consistent numerical advantages in favor of the CrossAction at all sites except lingual sites. Reductions in gingivitis were found to be similar with both toothbrushes.

Effect of electric toothbrushes versus manual toothbrushes on removal of plaque and periodontal status during orthodontic treatment.

This study compared the effectiveness of three different types of electric toothbrushes, i.e., Interplak, Philips, and Rotadent, with a manual multitufted toothbrush (Blend-a-Med), in removing supragingival plaque and in preventing the development of gingivitis in adolescent patients with fixed orthodontic appliances. A single blind, cross-over, clinical trial was carried out in 36 adolescent patients, randomly divided into four equal groups. Every group tested each type of toothbrush, in a different sequence. Plaque and gingival scores were recorded at baseline and after 1 and 2 months of the test period. All patients received a professional prophylaxis after each clinical evaluation, except during the test period. The analysis of the data was performed with the nonparametric Friedman test. The results demonstrated, in essence, for all parameters that the manual toothbrush was the most effective. Of the three electric toothbrushes tested, the Philips toothbrush seemed to give slightly better results than the Interplak toothbrush, whereas Rotadent very clearly gave results inferior to all others. Personal preference on the four toothbrushes used revealed that the group as a whole least preferred a manual brush. However, the answers on the questionnaire did not always show a logical consistency. Therefore it should be interpreted with some caution.

A 3-month clinical investigation comparing the safety and efficacy of a novel electric toothbrush (Braun Oral-B 3D Plaque Remover) with a manual toothbrush.

PURPOSE: To compare the efficacy and safety of a novel electric toothbrush (Braun Oral-B 3D Plaque Remover) with a standard reference ADA manual toothbrush. MATERIALS AND METHODS: 114 subjects were included in a 3-month randomized, parallel group, examiner-blind study and divided into two groups: 3D users and manual toothbrush users. Subjects were instructed to brush twice daily for 2 minutes. Evaluation of oral soft and hard tissue for safety, plaque, gingivitis and bleeding was conducted prior to the start of product use (at baseline), at days 14 and 35, and at 3 months. RESULTS: 105 subjects (55 3D users and 50 manual toothbrush users) completed the study. At days 14, 35 and at 3 months both groups showed reductions from baseline in whole mouth plaque, gingivitis and bleeding that were statistically significant (P < 0.005), except in the case of plaque at day 35 in manual toothbrush users. At 3 months, reductions for whole mouth plaque, gingivitis and bleeding were 15%, 16% and 65%, for 3D users and 8%, 12% and 56%, for manual toothbrush users, respectively. Group differences were significant (P < 0.05) in favor of the 3D with respect to plaque reduction for the whole mouth and for interproximal and anterior lingual sites at all three time periods. With respect to gingivitis, reductions for the whole mouth and interproximal and posterior lingual sites at 3 months were significantly greater in the 3D group. There was no clinically significant soft or hard tissue abrasion in either group. In conclusion, the 3D electric toothbrush was found to be safe and had increased efficacy with respect to reduction of plaque and gingivitis compared to a manual toothbrush.
