Laboratory interproximal access efficacy of two compact manual toothbrushes.

The Colgate Precision Compact, soft texture toothbrush and the Oral-B 35 toothbrush were compared using a laboratory device designed to simulate clinical toothbrushing motions and pressures. The toothbrushing time was sixty seconds for each vertical or horizontal toothbrushing sequence, for each of the three brushing weights tested (250, 500 or 750 g). Interproximal access efficacy (IAE) was determined by measuring the maximum width of the brushing stroke on pressure-sensitive paper placed around simulated anterior or posterior teeth. Twenty-four toothbrushes of each design were evaluated for each toothbrushing motion, tooth shape and toothbrushing weight. Using the vertical toothbrushing motion on anterior teeth, IAE means for the Colgate Precision Compact toothbrush were significantly higher (p < 0.001) than the Oral-B 35 toothbrush at 250 and 750 g of brushing weight. With vertical toothbrushing across posterior-shaped teeth, IAE values for the Colgate Precision Compact toothbrush were significantly higher (p < 0.001) than the Oral-B 35 toothbrush at each of the 250, 500 and 750 g brushing weights tested. With horizontal toothbrushing motions, the Colgate Precision Compact toothbrush had significantly higher (p < 0.001) IAE means, compared to the Oral-B 35 toothbrush, on both anterior and posterior tooth shapes and at each of the brushing weights tested. When all factors tested were combined, the total IAE for the Colgate Precision Compact toothbrush was significantly superior (p < 0.001) to the Oral-B 35 toothbrush.

Comparative efficacy of two battery-powered toothbrushes on dental plaque removal.

A number of clinical studies have consistently demonstrated that power toothbrushes deliver superior plaque removal compared to manual toothbrushes. Recently, a new power toothbrush (Crest SpinBrush) has been marketed with a design that fundamentally differs from other marketed power toothbrushes. Other power toothbrushes feature a small, round head designed to oscillate for enhanced cleaning between the teeth and below the gumline. The new power toothbrush incorporates a similar round oscillating head in conjunction with fixed bristles, which allows the user to brush with optimal manual brushing technique. The objective of this randomized, examiner-blind, parallel design study was to compare the plaque removal efficacy of a positive control power toothbrush (Colgate Actibrush) to an experimental toothbrush (Crest SpinBrush) following a single use among 59 subjects. Baseline plaque scores were 1.64 and 1.40 for the experimental toothbrush and control toothbrush treatment groups, respectively. With regard to all surfaces examined, the experimental toothbrush delivered an adjusted (via analysis of covariance) mean difference between baseline and post-brushing plaque scores of 0.47, while the control toothbrush delivered an adjusted mean difference of 0.33. On average, the difference between toothbrushes was statistically significant (p = 0.013). Because the covariate slope for the experimental group was statistically significantly greater (p = 0.001) than the slope for the control group, a separate slope model was used. Further analysis demonstrated that the experimental group had statistically significantly greater plaque removal than the control group for baseline plaque scores above 1.43. With respect to buccal surfaces, using a separate slope analysis of covariance, the experimental toothbrush delivered an adjusted mean difference between baseline and post-brushing plaque scores of 0.61, while the control toothbrush delivered an adjusted mean difference of 0.39. This difference between toothbrushes was also statistically significant (p = 0.002). On average, the results on lingual surfaces demonstrated similar directional scores favoring the experimental toothbrush; however these results did not achieve statistical significance. In conclusion, the experimental Crest SpinBrush, with its novel fixed and oscillating bristle design, was found to be more effective than the positive control Colgate Actibrush, which is designed with a small round oscillating cluster of bristles.

Comparative laboratory evaluation of two new toothbrushes regarding interproximal access efficacy.

The Colgate Precision toothbrush and the Crest Complete toothbrush were compared using a laboratory device designed to simulate clinical toothbrushing motions and pressures, allowing measurement of interproximal access efficacy. The toothbrushing time was sixty seconds for each vertical or horizontal toothbrushing motion and for each of the three brushing weights tested (250, 500 or 750g). Interproximal access efficacy was determined by measuring the maximum width of the brushing stroke on pressure-sensitive paper placed around simulated anterior or posterior-shaped teeth. Twenty-four toothbrushes of each design were evaluated for each toothbrushing motion, tooth shape and toothbrushing weight for a total of 576 measurements. Using vertical toothbrushing motions the Colgate Precision toothbrush had significantly higher (p < 0.01) interproximal access efficacy mean values, compared to the Crest Complete toothbrush on both anterior and posterior tooth shapes and at each of the brushing weights tested. Using the horizontal toothbrushing motion on anterior-shaped teeth, the interproximal access efficacy for the Colgate Precision toothbrush was significantly greater (p < 0.05) than the Crest Complete toothbrush at 750g of brushing weight. With horizontal toothbrushing across posterior-shaped teeth, interproximal access efficacy values for the Colgate Precision toothbrush were significantly greater (p < 0.01) than the Crest Complete toothbrush at the 250, 500 and 750g brushing weights tested.

Comparative laboratory evaluation of three toothbrushes regarding interproximal access efficacy.

A new toothbrush from the Colgate-Palmolive Company, called the Colgate Precision toothbrush, was compared to the Oral-B 40 toothbrush and Reach Full-Head soft toothbrush using a laboratory device designed to simulate clinical toothbrushing motions and pressures. The toothbrushing time was sixty seconds for each vertical or horizontal brushing motion and for each of the three brushing weights tested, 250, 500 or 750 grams. Interproximal access efficacy was determined by measuring the maximum width of the brushing stroke measured on pressure sensitive paper placed around the simulated anterior or posterior teeth. Twenty-four toothbrushes of each design were evaluated for each toothbrushing motion, tooth shape and toothbrushing weight for a total of 864 measurements. In all studies conducted, the Colgate Precision toothbrush had statistically superior total interproximal access efficacy scores compared to the Oral-B and Reach toothbrushes. In several assessments the Reach toothbrush was superior to the Oral-B 40 toothbrush.

The clinical effectiveness of a novel power toothbrush and its impact on oral health.

This review details the invention and clinical testing of a new power toothbrush designed to provide a low cost, effective toothbrush, which has a combination of a round oscillating head in conjunction with fixed bristles. The data demonstrate this power toothbrush (Crest SpinBrush) is an effective cleaning toothbrush with respect to plaque removal. Four independent 4-period crossover studies, where subjects used each brush twice, have demonstrated that brushing with this power toothbrush results in 10-40% greater plaque removal relative to a series of control manual toothbrushes. Separate research has confirmed that adults and children tend to brush longer, 35.8% and 38.3% respectively, when using this power toothbrush relative to manual toothbrushes. In addition, it has been shown to be superior to a battery-powered toothbrush (Colgate ActiBrush) in two independent studies and has demonstrated comparable efficacy to a leading powered toothbrush (Oral-B Ultra Plaque Remover). In parallel, this power toothbrush has also been shown to be safe relative to manual and power toothbrushes.

[Gingival abrasion and plaque removal with manual vs. electric toothbrushes].

In a clinical study, the relative incidence of gingival injuries after standardized tooth brushing was tested by 22 volunteer dental assistants whose teeth were brushed with a soft multi-tufted toothbrush, a manual V-form toothbrush, and an electric toothbrush. At the beginning of the study, a dental hygienist cleaned the right or left side of the jaw of each subject with a manual V-form toothbrush or an electric toothbrush; the other side was manually cleaned with a multi-tufted toothbrush. At the second cleansing one week later, the same dental hygienist cleaned the side contralateral to that brushed in the first test week with the multi-tufted brush; the manual V-form brush was used instead of the electric toothbrush and vice versa. The number of new gingival lesions was recorded after each brushing. The cleansing effect was established by determining the amount of residual plaque. The subjects did not know which type of toothbrush was used to cleanse the evaluated side of the jaw. The results showed that the manual V-form toothbrush abraded the gingiva more than the electric toothbrush (p less than 0.005). A similar difference was found between the manual multi-tufted and the electric toothbrush (p less than 0.05). No significant differences could be established with respect to the plaque-removing properties of the three types of toothbrush tested.

A study of gingival irritation and plaque removal following a three-minute toothbrushing.

Twenty-five subjects were assessed for plaque and soft tissue safety monitored by gingival irritation the first thing in the morning of day one following no toothbrushing for 12-14 hours. Subjects then brushed with either the Dentrust (manual toothbrush), Crest Complete (manual toothbrush) or Interplak (mechanical toothbrush) for a timed three minutes under supervision. The toothbrush assignments were by a table of random numbers. Following brushing, the subjects were assessed immediately for levels of plaque and gingival irritation. The subjects were then recalled three hours later for another assessment of plaque levels and residual gingival irritation from the morning toothbrushing. After three or four days the subjects were recalled to test an alternate toothbrush. Three or four days later the subjects were recalled to test the final toothbrush. Levels of irritation severity were evaluated using standard soft tissue examination procedures, and after rinsing with disclosing solution and photography, with subsequent blind judging of stain intensity and area on the gingiva by a panel of three experienced investigators. In the first morning assessment there was no significant difference among plaque or gingival appearance or stain uptake levels of the three groups before using the three toothbrushes. Immediately following toothbrushing, the three groups exhibited similar levels of plaque removal and clinical or stain-related gingival irritation. There was no significant statistical difference among the plaque or safety evaluations, although the Interplak toothbrush demonstrated higher irritation levels judged by stain uptake than the manual toothbrushes.(ABSTRACT TRUNCATED AT 250 WORDS)

Effectiveness of a sonic toothbrush in maintenance of dental implants. A prospective study.

This study assessed the efficacy of a sonic and a manual toothbrush in reducing plaque and gingivitis around dental implants. Subjects were randomly assigned to either sonic (n = 16) or manual (n = 15) study groups. Groups were balanced according to baseline levels of plaque and gingivitis. The plaque (PI), gingival (GI), and bleeding (BI) indices as well as probing depths were determined at baseline, and at 4, 8, 12, and 24 week follow-up visits. Mean scores per person were calculated for each clinical parameter. Oral hygiene habits, compliance and acceptance were also evaluated over the study period. Within group comparisons from baseline throughout the study, as well as between group comparisons (i.e., sonic versus manual), were determined. Overall, plaque, gingival, and bleeding indices in both groups were lower at each follow-up visit when compared to the baseline. Within group comparisons demonstrated that both the sonic toothbrush subjects and the manual toothbrush subjects had significantly lower PI, GI, and BI scores at each post-baseline visit (4, 8, 12, and 24 weeks) than at baseline (p<0.005). In addition, the sonic toothbrush subjects also had significantly lower probing depths at each post-baseline visit than at baseline (p < 0.005). Between group comparisons demonstrated that the sonic toothbrush subjects over time had significantly lower PI and BI scores around dental implants than the manual toothbrush subjects (Repeated measures MANOVA; PI, p = 0.01; BI, p = 0.017). The sonic toothbrush subjects had lower GI scores and reduced probing depths over time when compared to manual toothbrush subjects but these scores were not statistically significant (GI; probing depth, p > 0.05). No implant problems (e.g., loose screws) were attributable to the sonic toothbrush. Relevant to oral hygiene habits, subjects in both groups demonstrated a high level of compliance with their assigned toothbrush. Overall, the results of this study demonstrated that sonic toothbrushing significantly reduced plaque, gingival inflammation and bleeding, and probing pocket depths around implants over the 6-month trial period. It is concluded that sonic brushing is an effective means of dental implant maintenance.

A practice-based study of a power toothbrush: assessment of effectiveness and acceptance.

BACKGROUND: The greater effectiveness of the power toothbrush compared with a manual toothbrush is well-documented. Despite this, acceptance by dental professionals is still low. METHODS: This general practice study evaluated the effectiveness of a power toothbrush (Braun Oral-B Ultra Plaque Remover, Braun GmbH) in 16,903 patients, based on the clinical opinions of dental professionals in regard to patients' changing oral health status. In addition, a survey assessed the attitudes of dental professionals and patients toward the power toothbrush. RESULTS: The power toothbrush was considered by dental professionals to have had a positive effect on the oral health of 80.5 percent of their patients; the noticeable benefits with respect to a number of clinical criteria included plaque removal and improved gingival condition. Most patients in the study (88.9 percent) reported that they would continue using the power toothbrush once the study was completed. At the end of the study, many more dentists and hygienists considered the power toothbrush to be the most effective way of brushing, and almost 70 percent said that they would now be more likely to recommend a power toothbrush to their patients. CONCLUSIONS: The power toothbrush improved the oral health of patients in this practice-based study, and the number of dental professionals who said they would recommend a power toothbrush increased markedly during the study. CLINICAL IMPLICATIONS: Enabling dental professionals to evaluate the effect of a power toothbrush reinforces the findings from controlled clinical studies and increases their awareness of its potential to improve oral hygiene.
