Sonic and rotation-oscillation power toothbrushes are popular and effective, but have been shown to differ in relative benefits. The objective of this 12-week investigation was to compare the efficacy of a rotation-oscillation powered toothbrush and a newly introduced sonic toothbrush in the reduction of gingivitis and dental plaque.
                This was a randomized, controlled, examiner-blind, two-treatment, parallel-group study to assess gingivitis reduction and plaque reductions after twice-daily brushing with either the rotation-oscillation brush or the sonic toothbrush over 12 weeks. The Modified Gingival Index (MGI) and Gingival Bleeding Index (GBI) were used to determine gingivitis benefits at Week 6 and Week 12, and plaque was scored at these visits before and after supervised brushing using the Rustogi Modified Navy Plaque Index (RMNPI).
                In 171 evaluable subjects, gingivitis reduction benefits were significantly greater for the rotation-oscillation brush group than for those using the sonic toothbrush, with relative mean benefits favoring the rotation-oscillation brush of 29.4% for GBI and 8.2% for MGI at 12 weeks (p < or = 0.01). The rotation-oscillation brush produced significantly lower RMNPI plaque by 33.3% compared to the sonic toothbrush (p < 0.001) at Week 12.
                The rotation-oscillation power toothbrush was significantly more efficacious than the sonic toothbrush in removing plaque, in reducing gingivitis, and lowering the number of bleeding sites after 12 weeks of twice-daily brushing. Although power toothbrushes provide valuable tools toward improving oral health, contrasting results are discerned in their efficiency. This 10-week study was conducted to compare the safety and efficacy of rotation/oscillation and sonic power toothbrushes in the reduction of plaque and gingivitis.
                This two-treatment, parallel group, examiner-blind, randomized study had the subjects brush twice daily at home with their assigned rotation/oscillation or sonic toothbrush following manufacturer's instructions with center visits at baseline, and at 4 and 10 weeks following the baseline visit, for assessment of oral safety (all visits), plaque (baseline, Weeks 4 and 10), and gingivitis (baseline and Week 10). Gingivitis and number of bleeding sites were measured using the Löe-Silness Gingivitis Index, and plaque was measured using the Turesky Modification of the Quigley-Hein Plaque Index.
                At Week 10, 171 subjects were evaluable for plaque assessment (85 in Sonic group, 86 in rotation/oscillation group) and 165 subjects were evaluable for gingivitis and bleeding sites assessment (84 in sonic group, 81 in rotation/oscillation group). The rotation/oscillation group had statistically significantly lower gingivitis scores (by 3.5%) and statistically significantly fewer bleeding sites than the sonic group (by 16.1%) with P = 0.038 and 0.028, respectively, at Week 10. Compared to baseline, only the rotation/oscillation group showed a statistically significant improvement in gingivitis (P = 0.003) and bleeding (P < 0.001) at Week 10. At both Weeks 4 and 10, the rotation/oscillation group had directionally lower plaque scores than the sonic group (by approximately 3%), but treatment group differences were not statistically significant (P > 0.1) at either time point. Both groups showed statistically significantly lower plaque scores at Weeks 4 and 10 relative to baseline. To compare the efficacy on plaque, gingivitis and calculus of an oscillating/rotating power toothbrush (Braun Oral-B Ultra Plaque Remover-D9) and a high frequency toothbrush (sonicare).
                A 6-week, randomized crossover study was carried out. A total of 62 healthy adult subjects completed the study and were assessed for plaque control, gingival condition and calculus control. At the end of the study, subjects completed a questionnaire which assessed their preferences for the two devices.
                Both toothbrushes were found to be safe and effective, but a significantly lower gingival index (P = 0.002) and a lower calculus index (P = 0.022) was found in the D9 group. Assessment of patient preferences revealed that a significant majority of subjects in the study (65%) preferred the D9 to the high frequency toothbrush (27%). It is concluded that the D9 may offer greater potential for the maintenance of good gingival condition than the high frequency toothbrush, and that the greater preference for the D9 may be important with respect to long-term compliance. The implications of these findings are discussed. This clinical study compared the ability of a sonic toothbrush to remove plaque and control gingivitis with that of an oscillating/rotating electric toothbrush. One-hundred and sixteen subjects from a general population were randomly allocated to either a sonic toothbrush group (Sonicare) or an electric toothbrush group (Braun Oral-B Plaque Remover). After 8 weeks use, there was found to be no statistically significant difference in either plaque removal or gingival index between the two groups. Both devices were found to be safe, but whereas 100% of volunteers in the Braun Oral-B Plaque Remover group expressed a wish to continue using the toothbrush, approximately 25% of the Sonicare group did not like the device and said that they would not continue to use it. The Sonicare device was found to offer no advantages in clinical terms over an established oscillating/rotating electric toothbrush (Braun Oral-B Plaque Remover) with respect to removal of supragingival plaque or improvement in gingival health. The purpose of this study was to evaluate the safety and efficacy of the Braun Plak Control for the removal of supragingival plaque and improving gingival health in a long-term clinical trial, and to compare it to regular manual toothbrush. Assessed were plaque accumulation, amount of gingival inflammation, gingival bleeding on probing, and calculus. In total, 77 young individuals were selected on the basis of having 'moderate gingivitis'. They were monitored over 8 months and divided among 2 groups; a control group that used a manual toothbrush and a test group that used the Braun Plak Control. The clinical assessments were repeated after 1, 2, 5, and 8 months. At baseline, subjects were handed their assigned toothbrushes together with written oral hygiene instructions. They were instructed to brush for at least 2 min. 1 month after baseline examinations, all subjects received a professional prophylaxis and oral hygiene instruction from an experienced dental hygienist. Plaque removal was reinforced at the 2-and 5-month examination. In conclusion, results indicate that the Braun Plak Control is a safe and efficient home care device. At the end of this trial, this electric toothbrush proved to be more effective than a regular manual toothbrush. The objective of this study was to evaluate the effect of an oscillating/rotating/pulsating powered toothbrush on plaque and gingivitis prevention over a 9-month period.
                The study had an examiner-masked, randomized, three-group parallel design. A total of 122 subjects >or= 18 years of age in good general health and with at least five teeth per quadrant and no pockets >or= 5 mm were included. A 3-week preexperimental period of extensive oral home care, including rinses, was started to improve gingival health. Professional oral hygiene instruction with a manual brush was provided. At baseline, subjects were assigned to one of three regimens: twice daily brushing with a manual toothbrush, a manual toothbrush and the use of floss, or a powered toothbrush. Subjects were professionally instructed in their regimen and given a prophylaxis. Two weeks later, oral hygiene reinforcement was provided. Gingival bleeding, plaque, staining, and gingival abrasion were assessed during the preexperimental period and at baseline, 10 weeks, and 6 and 9 months.
                There was a significant reduction in plaque and gingivitis from the preexperimental period to baseline. At 10 weeks and 6 and 9 months, the level of plaque was statistically significantly lower with the powered toothbrush versus the other two regimens (P <or= 0.002). At 10 weeks and 6 months, the level of bleeding in the powered toothbrush group was statistically significantly lower versus manual brushing alone (P <or= 0.024).
                The powered toothbrush maintained lower plaque levels for 9 months following the 3-week treatment phase better than the manual toothbrush with or without floss. The powered toothbrush showed significant benefits in preventing gingival bleeding versus manual brushing alone. All regimens were safe for oral tissues. The purpose of the present investigation was to compare manual (Crest Complete) and powered toothbrushing (Braun Oral-B 3D Plaque Remover) for their ability to affect clinical parameters of periodontal diseases.
                48 periodontal maintenance subjects completed this single-blind 6-month longitudinal study. Subjects had a minimum of 20 natural teeth excluding third molars and >10% of sites (approximately 17 sites) with pocket depth > or =4 mm and/or >10% sites with attachment level >4 mm. At baseline, subjects received full mouth clinical measurements (168 sites) to determine mean Plaque Index, Gingival Index, pocket depth and attachment level and % of sites exhibiting BOP. Subjects were then randomly assigned to one of two groups. The control group (N=26) used a manual toothbrush while the test group (N=22) used a powered toothbrush. Subjects received instruction in oral hygiene and used their assigned toothbrush twice daily according to instruction. Follow-up clinical assessments were performed at 3 and 6 months. Significance of differences in clinical measures over time was determined using the Quade test and between brushing groups at each time point using the Mann-Whitney test.
                Mean pocket depth, mean plaque index and % of sites exhibiting BOP showed significant reductions from baseline to 3 and 6 months in both groups. Mean probing attachment level and mean Gingival Index were significantly reduced in the powered brushing group only. There was a significant positive correlation between plaque reduction and reduction in other clinical parameters in both brushing groups. The majority of subjects showed improvements in clinical parameters at 6 months, although a greater proportion of subjects in the powered group showed a reduction in Plaque Index (77% versus 65%) and in % sites exhibiting BOP (82% versus 69%). Mean pocket depth and mean attachment level showed significantly greater reductions between baseline and 6 months in lingual and mandibular areas in the powered group.
                Both manual and powered toothbrushes reduced pocket depth, plaque index and BOP. The powered toothbrush significantly reduced mean gingival index and probing attachment level. The greatest benefit of the powered brush was at mandibular and lingual surfaces. The clinical effectiveness of a manual ionic toothbrush in the removal of dental plaque and the reduction of gingivitis was evaluated. A double-blind study evaluated the effect of a small, imperceptible electric current on established dental plaque and gingivitis during toothbrushing. Sixty-four adults completed the study. Gingivitis and plaque scores were determined at baseline and after 3 and 6 months. The baseline indices of the two groups were well balanced. At each examination, the participants were instructed how to hold the toothbrush properly and reminded to change brush heads every 4 weeks. Statistically significant improvements in Löe Gingival Index scores were observed from baseline to 6 months between the control and test groups and within the test group. The Quigley-Hein Plaque Index scores also showed a significant improvement from baseline to 6 months between the control and test groups and within the test group. The aim of this 12-month parallel design controlled clinical trial was to assess the effect of the Braun Oral-B Plak Control electric toothbrush on supragingival plaque and gingival health, and to compare it with a conventional soft manual toothbrush (Jordan). A total of 111 patients aged between 20 and 63 years, from a general population, with bleeding on probing at 30% or more of all sites examined were entered into the study. At baseline, immediately after periodontal examination, all volunteers received a thorough scaling of their teeth. Volunteers in both groups were told to brush their teeth for 2 min 2 x a day. Oral hygiene instruction was given at the start of the study and was not repeated. At 3, 6 and 12 months, assessments were carried out by a single clinician who was not aware which group the volunteers belonged to. Analysis of results demonstrated that over the 12 months of the study, the Braun Oral-B Plak Control was significantly more effective in improving gingival health than the manual toothbrush. There was, however, no difference between the 2 groups in terms of plaque removal, with the number of sites with visible plaque decreasing by a similar amount in both groups. In conclusion, results indicate that the Braun Oral-B Plak Control toothbrush is safe and more effective than a manual toothbrush in improving gingival health. This three-month clinical trial was designed to compare the effect of an electric and a manual toothbrush on reducing primarily gingivitis and secondarily, plaque, in a cohort of 70 healthy adults. After baseline evaluation of gingivitis, soft tissue trauma, and plaque, patients were randomly assigned to one of the two experimental groups, shown an instructional tooth brushing videotape, and had their teeth cleaned. Soft tissue trauma was again scored at 2 weeks. At 12 weeks all three clinical parameters were again evaluated. The results showed statistically significant reductions (baseline vs. 3-month) in both whole mouth (p = 0.003) and interproximal (p = 0.008) gingivitis scores for the electric toothbrush group. No significant reduction at three months compared to baseline was seen for the manual brush group. When gingivitis reductions were compared over the three-month test period, the electric brush was significantly better than the manual toothbrush in both whole mouth (p = 0.0007) and interproximal (p = 0.002) gingivitis reduction. No increase in soft tissue trauma and no significant differences in plaque reductions were seen for either 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. A single blind 30 day study compared the reduction of plaque and gingivitis for the Hapika Powerbrush to the Interplak ultra 10 tuft. A longitudinal parallel group design was utilized and screening evaluation was performed to determine patient eligibility prior to study enrollment, 66 subjects were entered into the study and assigned to 1 of 2 groups, each using one of the toothbrushes. At baseline, subjects received an oral soft tissue exam, a dental hard tissue exam, and were scored by the Lobene modification of the Löe and Silness gingival index (GI). Plaque was then disclosed and scored both pre and post brushing using the modified Turesky plaque/debris examination and an interproximal bleeding examination was performed post-brushing. On days 15 and 30, after an oral soft tissue and GI examination, plaque was graded by the Modified Turesky plaque/debris exam. Subjects then brushed and were graded by the Modified Turesky plaque/debris examination and an interproximal bleeding index examination. The results showed that both brushes provided a similar change in clinical indices. All produced a statistically significant reduction from baseline to day 30 for the gingival index (26.5-29.1%), the bleeding index (13.8-24.1%), and the plaque index (16.9-19.4%). A comparison of pre and post brushing scores for the plaque index at 30 showed that both brushes reduced plaque similarly with a statistically significant reduction (P < 0.05) from their pre-brushing plaque index scores at all time periods. 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. This single (examiner) blind, randomized, 4-week study compared the safety and efficacy of a new electric toothbrush (experimental) regarding plaque removal and reducing gingivitis with two other brushes, an electric brush (control electric) and a manual toothbrush (control hand). Ninety-six subjects with 1) a minimum of 15 suitable teeth in acceptable occlusion; 2) a minimum gingivitis score of 0.9; and 3) a minimum plaque score of 1.8 were entered into the study. The subjects were randomly assigned to one of 3 groups: a control hand group (31 subjects), an experimental group (32 subjects), and a control electric group (33 subjects). Device use instructions were given according to the manufacturer's recommendations. Two examiners separately determined either gingival scores or plaque scores at baseline and 4 weeks. In regard to gingivitis, use of all 3 brushes for the study period showed statistically significant improvements in gingivitis scores (P values less than 0.01) within each of the 3 groups. Between group analyses of covariance showed that of the 3 groups, the control hand group improvement was better than both the experimental and the control electric groups (P less than 0.05). When interproximal gingivitis scores were analyzed separately, similar improvements were noted. Regarding effectiveness of plaque removal during a single brushing event at the initial and final visits, each of the 3 brushes was effective in reducing plaque for every tooth surface scored (P values less than 0.01). However, between group analyses of covariances showed that the experimental group was better than the other two (P less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS) The aim of the present study was to evaluate the efficacy of an electric toothbrush with a specially designed orthodontic brush head compared with a manual toothbrush in controlling plaque and gingivitis in patients with fixed orthodontic appliances over an 8-week period in a dental practice setting.
                This was a randomised controlled, single blind, stratified, parallel group trial conducted in two specialist orthodontic dental practices by a specialist orthodontist. Group 1 comprised 41 subjects who used the electric toothbrush and Group 2 consisted of 43 subjects who brushed with a manual toothbrush around the orthodontic appliance for a timed 2 minutes twice daily for 8 weeks. Plaque around the fixed appliance attachments was measured using an orthodontic modification to the Silness and Loe plaque index, while gingival condition was scored using the gingival index and Eastman interdental bleeding index.
                There was baseline balance for all clinical variables (p > 0.05). Both groups had significantly less plaque after 8 weeks than at baseline (p < 0.001) but the group using the electric brush also had significantly less interdental gingival bleeding, as determined by the Eastman interdental bleeding index both at week 4 (p < 0.001) and week 8 (p = 0.004). The majority of subjects (n = 54, 64.3%) preferred the electric toothbrush.
                In conclusion, the results from this study would suggest that use of an electric toothbrush with an orthodontic brush head may be of benefit in promoting gingival health in fixed orthodontic appliance patients; however, the long-term effects (over at least 6 months) need to be evaluated. This investigation was undertaken to determine if an ionic toothbrush was effective at removing plaque and reducing gingivitis in patients wearing orthodontic appliances. Fifty-two orthodontic patients were randomly assigned to one of two groups and completed a six-week double-blind study. Group 1 consisted of the test group using the ionic toothbrush with an active battery; group 2 consisted of the control group using the ionic toothbrush with an inactive battery. The plaque and gingival indices were measured at baseline, two weeks, and six weeks. The findings demonstrated that the active ionic toothbrush was no more effective at plaque removal and gingivitis reduction than the inactive toothbrush. Although the active toothbrush did effectively remove plaque and reduce gingivitis over the course of six weeks, it showed no significant improvement over the same toothbrush that contained an inactive battery. It was observed that the ionic toothbrush effectively reduced plaque and gingivitis regardless of the presence or absence of an active battery. The clinical findings demonstrated that an active ionic toothbrush was no more effective in removing plaque and reducing gingivitis in patients with orthodontic appliances than an inactive ionic toothbrush.
There is some evidence that rotation oscillation brushes reduce plaque and gingivitis more than side to side brushes in the short term. This difference is small and it's clinical importance is unclear. Further trials of good quality are required to assess the superiority of other modes of action for powered toothbrushes.
