... The specimens were placed in a special device with the exact measurements of the discs to restrict the brushing area. The electrical toothbrush contains a smart pressure sensor that provides positive feedback by providing a green light when optimal pressure (0.8-2.5 N) is used [20]. All discs were brushed for 3 s, corresponding to 1 day of brushing (84 sites, 240 s of brushing per day, 240/84 = 2.9 s per site per day). ...
Background: New lithia-based glass–ceramics, including Advanced Lithium Disilicate (ALD), have become popular in dentistry. However, it is unclear if glazing protocols for ALD might compromise its surface or optical properties. Thus, evaluating color and translucency changes in ALD and traditional lithium disilicate (LD) is crucial. Methods: This study aimed to assess how different firing protocols affect the surface and optical properties of LD and ALD. Sixty disc-shaped specimens were prepared, divided into three subgroups based on firing protocols, and subjected to surface roughness analysis. Specimens were immersed in coffee, wine, and water for 7 days, and then brushed. Color and translucency were measured. Results: Firing protocols significantly influenced surface roughness in LD (0.09–1.39 µm) and ALD (0.05–0.88 µm). Color differences were observed in both LD and ALD after 7 days, with visible changes within clinically acceptable thresholds. Translucency remained stable across firing protocols and staining liquids. Conclusions: Varying firing protocols impact surface roughness and color stability in LD and ALD. Despite differences, color and translucency changes remained within acceptable clinical thresholds, suggesting both materials are suitable for dental applications. Therefore, this study reinforces the reliability and versatility of these materials in restorative dentistry.
... In the 1950s and 1960s, electric-mechanical toothbrushes with high plaque-removal efficiencies were developed [22,23]. These toothbrushes have a higher plaque-removal rate than regular toothbrushes because the electric motor utilizes rotational and planar vibration [24][25][26]; however, they cause tooth wear [27]. Moreover, electric-mechanical toothbrushes can accelerate tooth wear when used in conjunction with charcoal toothpaste [28]. ...
... The BE is effective in removing biofilms, such as plaque, which corresponds to the previous finding that the BE toothbrush significantly amplified plaque removal [21]. Electric-mechanical toothbrushes have a higher plaque removal rate than regular toothbrushes [24][25][26]. However, no significant differences were observed between the BE-on and MB groups. ...
... A significant reduction in residual plaque was observed for the MB and BEon toothbrushes when compared with that of manual toothbrushes. MBs are more efficient for plaque removal than manual toothbrushes because of the mechanical rotation of their bristles [24][25][26]. We observed a significant reduction in the residual plaque when using BE-on compared with that of a manual toothbrush, which corresponded to the results of previous studies [21]. ...
Effective oral care is important for maintaining a high quality of life. Therefore, plaque control can prevent the development and recurrence of periodontitis. Brushing with a toothbrush and toothpaste is a common way to remove plaque; however, excessive brushing or brushing with abrasive toothpaste can cause wear and tear on the dental crown. Hence, we aimed to quantitatively compare the plaque-removal efficiency and tooth wear of toothbrushes using the bioelectric effect (BE) with those of electric–mechanical toothbrushes. To generate the BE signal, an electronic circuit was developed and embedded in a toothbrush. Further, typodonts were coated with cultured artificial plaques and placed in a brushing simulator. A toothpaste slurry was applied, and the typodonts were eluted with tap water after brushing. The plaques of the typodonts were captured, and the images were quantified. For the tooth wear experiment, polymethyl methacrylate disk resin blocks were brushed twice a day, and the thickness of the samples was measured. Subsequently, statistical differences between the experimental toothbrushes and typical toothbrushes were analyzed. The BE toothbrush had a higher plaque-removal efficiency and could minimize tooth wear. This study suggests that the application of BE may be a new solution for oral care.

... One possible explanation for this discrepancy is the advanced brushing mechanisms found in electric toothbrushes, such as oscillating or rotating brush heads, which may enhance cleaning efficiency and reduce the need for a large amount of toothpaste. 25,26 This aspect of electric toothbrushes not only has implications for toothpaste consumption but also for optimizing plaque removal and overall oral health. It is worth noting that the study had a relatively small sample size, consisting of only 10 participants. ...
Objective Toothpaste is a crucial component of daily oral hygiene routines and is significant in maintaining oral health. This study aimed to assess the amount of toothpaste consumed during tooth brushing and investigate the influence of toothbrush type on toothpaste consumption.
Materials and Methods Ten volunteer students of dentistry who regularly practiced oral hygiene at home were enrolled. Participants used a 15-mL tube of toothpaste with manual and electric toothbrushes and the amount consumed was recorded three times daily.
Statistical Analysis Variance analysis for repeated measures was applied for differences within groups for toothbrush types while the t-test was carried out to compare the mean quantities between groups. Statistical significance was set at p < 0.05.
Results The findings revealed no significant difference in toothpaste consumption across different time intervals for both manual and electric toothbrushes. However, a significant difference in toothpaste consumption was observed when comparing toothbrush types. Participants using electric toothbrushes consumed less toothpaste compared to those using manual toothbrushes.
Conclusion The observed differences in toothpaste consumption highlight the importance of considering toothbrush type when promoting appropriate usage. With their advanced brushing mechanisms, electric toothbrushes may enhance cleaning efficiency and reduce the need for a large amount of toothpaste. Reducing toothpaste consumption benefits oral health and contributes to environmental sustainability. It minimizes packaging waste, conserves energy and resources, promotes water conservation, preserves ecosystems, and encourages a culture of ecological responsibility. By embracing a more conscious approach to toothpaste usage, individuals can contribute to a greener and more sustainable future.
... The majority of studies have focused on the impact of electric toothbrush brands on consumer experience. Firstly, Adam (2020) aims to investigate the advantages of Oral-B electric toothbrush in removing dental plaque compared with traditional toothbrush. This was a comparative study in which 27 participants were assigned to two groups. ...
... In addition, the incorrect brushing method is also one of the reasons for the poor cleaning performance of traditional toothbrushes. Compared with the research design of Adam (2020), the research of Adam et al. (2020) used experimental methods to compare the cleaning effect of two different electric toothbrushes of Philips and Oral-B on users' dental plaque. Participants using both electric toothbrushes were asked to brush their teeth the same way, which added credibility to the study's findings. ...
Oral diseases have a lot of adverse effects on people’s health. Oral care has become an important part of People’s Daily maintenance of oral health. The purpose of this paper was to investigate the relationship between the type of electric toothbrush and a specific oral care population. This study will use the method of secondary research to review the relevant literature to answer the research questions. The results show that Oral-B is superior to Philips in both the treatment of gingivitis and plaque, but the Philips toothbrush still cleans better than a manual toothbrush. Secondly, children with disabilities can benefit from electric toothbrushes, because electric toothbrushes provide better plaque removal than manual toothbrushes. However, electric toothbrushes do not give disabled children the same cleaning results as ordinary people. Thirdly, in terms of enamel wear, sonic toothbrushes wear enamel more severely than vibrating toothbrushes. However, in terms of cementum, sonic toothbrush has less damage to cementum. In general, sonic toothbrushes are less harmful than vibrating toothbrushes. Practically speaking, this study suggests that ordinary consumers should choose Oral-B toothbrush more often than Philips toothbrush. Moreover, it is suggested that disabled children use electric toothbrushes to achieve better cleaning effect. However, as ordinary electric toothbrushes cannot make up for the defects of disabled children, it is suggested that relevant health institutions develop electric toothbrushes specially for disabled children. Furthermore, for those with sensitive and fragile teeth, the study recommends that they use a sonic toothbrush instead of vibrating toothbrush.
... 11 Electric toothbrushes have evolved to include built-in timers, pressure sensors, expanded brushing modes, and Bluetooth-connected apps to increase brushing time and thoroughness. 12,13 The majority of contemporary electric toothbrushes are classified as sonic (side-to-side motion) or oscillating-rotating (O-R). Evidence shows greater gingivitis and plaque reduction for the latter technology. ...
... The linear magnetic drive produces micro-vibrations at bristle tips, which might augment plaque removal. 12 In light of the significant design changes associated with the latest O-R model, this investigation was undertaken to extend the reach of the prior meta-analysis and compare the efficacy of O-R toothbrushes, including the latest model, with manual negative control and sonic positive control toothbrushes in reducing gingivitis and plaque in RCTs with up to 6 months' follow-up. It also offers new perspectives on the data. ...
... The iO O-R toothbrush incorporates a linear magnetic drive system that directs energy to brush filaments tips-eliminating intrinsic losses of energy that are incurred with use of mechanical drive systems in earlier models of oscillating rotating brushes-inducing micro-vibrations at the site of plaque removal. 12 The superiority of this brush vs manual 28,29,50 and sonic 30,31 brushes has already been demonstrated in studies of plaque and gingivitis reduction after as much as 6 months of use; the current results further confirm evidence of the iO brush as an effective oral health tool. ...
Background:
Research continues to show an association between oral health and systemic health, further stressing the importance of effective daily plaque removal via toothbrushing to maintain periodontal health and overall well-being. This investigation was undertaken to compare the efficacy of oscillating-rotating, sonic, and manual toothbrushes in reducing gingivitis and plaque in randomised controlled trials (RCTs) with up to 6 months' follow-up.
Methods:
This meta-analysis was conducted from a single database (Procter & Gamble Oral Care Clinical Archive) including RCTs from 2007 to 2022. Three authors independently assessed study eligibility. Disagreements concerning selected studies were resolved by discussion with an expert colleague. Direct and indirect treatment comparisons along with transition rates to gingival health were calculated using participant-level data. Transition-to-health time was calculated using data from all time points. Subregion analyses evaluated number of bleeding sites and plaque reduction.
Results:
This meta-analysis included 21 gingivitis RCTs and 25 plaque RCTs. Relative to manual and sonic brushes, oscillating-rotating brushes had a higher percentage of participants who transitioned to gingival health (72% vs 21% and 54%; P < .001). Compared with manual and sonic brushes, respectively, oscillating-rotating brushes demonstrated greater bleeding site reductions (by 52% and 29%; P < .001) and superior plaque reductions (by 19% and 5%; P < .001). Oscillating-rotating brushes provided faster transitions to health than sonic brushes and showed greater efficacy across subregions. The most advanced oscillating-rotating brush demonstrated statistically significantly greater efficacy compared with traditional oscillating-rotating, manual, and sonic brushes when analysed separately. Risk of bias was deemed low for all studies.
Conclusions:
Oscillating-rotating toothbrushes offer superior results for transition to health, gingivitis, and plaque reduction compared with manual and sonic brushes. The most advanced oscillating-rotating model offers enhanced efficacy vs traditional models.
... The ultrasonic toothbrush refers to any electric toothbrush whose movement speed is higher than these limits. These two can not only clean the accessible area of the tooth surface with mechanical polishing but also dislodge the surface stains and bacteria by the high-frequency vibration of the bristles with fluid pressure and shear force [15]. ...
With the continuous improvement of people's income level, people can enjoy more and more delicious food. At the same time, the emphasis on oral health has reached a new level in order to enjoy good food. The toothbrush is a product closely related to oral health in People's Daily life. The combination of human factors, industrial design, and engineering design will result in products with outstanding function and beautiful appearance. An excellent toothbrush is no doubt based on people's good experience at the core, combined with innovative industrial design to produce products. This article aims to compare the advantages and disadvantages of different toothbrushes and analyze the effects of different structural designs of toothbrushes on plaque removal and gingivitis inhibition. The study found that electric toothbrushes were significantly better than manual toothbrushes at removing plaque. Both are effective in reducing gingivitis, but the difference is not significant. Based on this article, in daily life to clean the mouth, the best choice of rotary vibration electric toothbrush is to clean dental plaque.
... We kept the application speed and force in a narrow range to reduce the impact of those factors on the whitening effect. For instance, brushing force ranged from 0.8 to 2.5 N [41]. The sensor light changes colors according to brushing force, which helps to maintain consistent pressure in the optimal range. ...
Background
The aim of this study was to evaluate the postbrushing tooth-whitening effect of toothpaste containing hydroxyapatite nanoparticles (nano-HAPs). The impact of the concentration on the whitening performance of nano-HAP toothpaste was also investigated.
Methods
Two concentrations of nano-HAP (10 wt% and 1 wt%) were incorporated in nonabrasive toothpastes. Forty bovine incisors were randomly assigned into four groups: 10 wt% nano-HAP, 1 wt% nano-HAP, toothpaste without nano-HAP as a negative control and water as a blank control. Each tooth was treated with the toothpaste three times and hydrodynamic shear force (HSF) once. The teeth surfaces were observed by SEM after each application. Tooth color ( L *, a * and b * values) was measured by a spectrophotometer, and color changes (△ E , △ L , △ a and △ b values ) were calculated. Two-way mixed ANOVA was performed to evaluate the influence of the concentration and repeated application on the tooth-whitening effect of nano-HAP.
Results
We found that nano-HAP-treated enamel exhibited higher L* values and lower a * and b * values than the control groups ( P < 0.05). The 10 wt% nano-HAP group showed significantly higher △ E values than the 1 wt% nano-HAP group ( P < 0.05). After three applications, the △ E mean value of the 10 wt% nano-HAP group was 4.47. The △ E and △ L values were slightly reduced after HSF ( P < 0.05). For both nano-HAP groups, HAP single crystallites and agglomerates were identified, and their sizes grew with nano-HAP reapplication.
Conclusions
In conclusion, nano-HAP toothpaste has a satisfying postbrushing whitening effect and good resistance to mechanical forces. The whitening effect seemed to be concentration-dependent.
... Philippe Guy Woog, a Swiss dentist, invented the first electric toothbrush in 1939 and dubbed it the broxodent, which made cleaning teeth simpler (Adam, 2020). Since then, other innovators have continued to advance the innovation of the electric toothbrush to more efficient ones. ...
... Since then, other innovators have continued to advance the innovation of the electric toothbrush to more efficient ones. The current electric toothbrush recommended by dentists is "Oral-B GENIUS X Electric Toothbrush", which is rechargeable (Adam, 2020). Compared to the manual toothbrush, which makes 600 movements, the Oral-B GENIUS X Electric Toothbrush has rotating and oscillating bristles, which make 48,000 brush movements. ...
... Electric brushes might significantly improve the brushing effectiveness of dental laypeople as compared to manual toothbrushes. This idea is confirmed by a recent meta-analysis conducted by Adam (2020), who found a slight but substantial benefit for electric toothbrushes over manual toothbrushes in terms of gingivitis and dental hygiene. The most modern toothbrush types include straighter, curved, angled, and contoured handles with grips and soft rubber regions to make them simpler to grasp and operate (Re, et al., 2015). ...
... Recently, an O-R toothbrush with micro-vibrations (Oral-B® iO) 25,26 has demonstrated greater plaque removal and gingivitis reduction relative to that of both manual and sonic toothbrushes. This level of performance has been observed after a single brushing and throughout studies lasting 8, 12, and 24 weeks 17,27− 29 . ...
This study aimed to compare dental plaque regrowth dynamics across 8 days between an oscillating-rotating (O-R) electric toothbrush and a manual toothbrush using Digital Plaque Imaging Analysis (DPIA). A randomized crossover trial involving adult participants with ≥10% plaque coverage on anterior teeth was conducted. Thirty-four subjects were randomized to one of 4 treatment sequences, each having four 8-day treatment periods. Subjects brushed twice daily with the assigned toothbrush. Morning and afternoon plaque were evaluated on days 1, 3, and 8. The primary variable was afternoon percent plaque coverage, evaluated across 8 days.
The O-R toothbrush produced lower mean plaque levels versus the manual toothbrush for all endpoints over 8 days (P≤0.001). The benefit for the O-R toothbrush increased over time, demonstrating 16.4% and 28.1% lower afternoon plaque levels on Days 1 and 8, respectively compared to the manual brush. Trends were similar for morning plaque. Repeated measures analyses showed a 21.2% reduction in overall afternoon plaque and a 23.5% reduction in overall morning plaque for the O-R brush versus the manual brush (P < 0.001). The O-R toothbrush resulted in less overnight and afternoon plaque regrowth versus the manual toothbrush at all time points, and the benefit increased over 8 days.
