It is the habit not the handle that affects tooth brushing - a randomised counterbalanced cross over study with young and healthy adults.

OBJECTIVE: To assess the effect of the toothbrush handle on video-observed toothbrushing behaviour and toothbrushing effectiveness. METHODS: This is a randomized counterbalanced cross-over study. N = 50 university students and employees brushed their teeth at two occasions, one week apart, using either a commercial ergonomically designed manual toothbrush (MT) or Brushalyze V1 (BV1), a manual toothbrush with a thick cylindrical handle without any specific ergonomic features. Brushing behaviour was video-analysed. Plaque was assessed at the second occasion immediately after brushing. Participants also rated their self-perceived oral cleanliness and directly compared the two brushes regarding their handling and compared them to the brushed they used at home. RESULTS: The study participants found the BV1 significantly more cumbersome than the M1 or their brush at home. (p < 0.05). However, correlation analyses revealed a strong consistency of brushing behavior with the two brushes (0.71 < r < 0.91). Means differed only slightly (all d < 0.36). These differences became statistically significant only for the brushing time at inner surfaces (d = 0.31 p = 0.03) and horizontal movements at inner surfaces (d = 0.35, p = 0.02). Plaque levels at the gingival margins did not differ while slightly more plaque persisted at the more coronal aspects of the crown after brushing with BV1 (d = 0.592; p 0.042). DISCUSSION: The results of the study indicate that the brushing handle does not play a major role in brushing behavior or brushing effectiveness.

In-Vitro Tooth Cleaning Efficacy and Filament End Rounding of Different Manual Children's Toothbrushes.

PURPOSE: This in-vitro study aimed to investigate the cleaning efficacy of 18 different manual children's toothbrushes applying horizontal, vertical, and rotational movements, as well as to evaluate the rounding of their filament ends. MATERIALS AND METHODS: Models equipped with artificial teeth (coated with titanium dioxide) were brushed using a brushing machine with clamped manual children's toothbrushes. The machine carried out horizontal, vertical, and rotational movements for 1 min with a constant contact pressure of 100 g. The percentage of the area of titanium dioxide removed from the buccal, mesial, distal and total surfaces of the artificial teeth corresponded to the cleaning efficacy. To assess the filament design, a scanning electron microscope was used to check the morphology of the filaments which was scored with Silverstone and Featherstone scale. SPSS 22 was used for data analysis. RESULTS: The rotational and the vertical movements achieved the best cleaning efficacy with all tested toothbrushes. The vast majority of the tested toothbrushes had their poorest cleaning efficacy in the horizontal movement. Only a small part of the children's toothbrushes (3 out of 18) had a correct and acceptable proportion of rounded bristle ends. CONCLUSIONS: Based on the present results, it could be concluded that the cleaning efficacy of different manual children's toothbrushes varied considerably. The best cleaning efficacy was almost always observed for rotational and vertical movements.

Minimal changes in daily flossing behavior among US adults from 2009 through 2020.

BACKGROUND: Flossing is considered to be an integral component of oral hygiene. The authors evaluated trends in daily flossing and their associations with sociodemographic variables. METHODS: The authors used data from the 2009-2020 National Health and Nutrition Examination Surveys, accounting for survey weights in all analyses. Descriptive statistics were computed for all study variables. Pooled univariable and multivariable logistic regression were performed to evaluate which sociodemographic factors were associated with daily flossing and to assess potential interactions with survey periods. Multivariable logistic regression was performed and stratified according to survey period. RESULTS: This study included 26,624 adults. Although the prevalence of daily flossing increased from 29.4% in 2009 through 2010 to 34.8% in 2017 through 2020, this increase was not significant after multivariable adjustment. Results of the pooled survey logistic regression also showed that participants who were older, female, Hispanic, and had a higher income to poverty ratio had higher odds of daily flossing. The interaction between education and survey period was significantly associated with daily flossing (P = .012). Logistic regression for each survey period corroborated the pooled model results. CONCLUSIONS: Approximately 1 in 3 adults in the United States reported flossing daily (32.7%). Although the prevalence of daily flossing increased from 2009 through 2020, this change was not significant after controlling for sociodemographic variables. PRACTICAL IMPLICATIONS: The nonsignificant changes in flossing behavior from 2009 through 2020 suggest that messaging to encourage adults to floss daily has had little effect. Although the authors did not elucidate the benefits of flossing, dental providers should continue to consider encouraging patients to floss until new evidence suggests otherwise.

Effectiveness of dental floss in the management of gingival health: A 6-month follow-up of a randomized controlled clinical trial.

OBJECTIVES: To evaluate, (i) if subjects submitted to a structured oral hygiene training program (OHt) maintain adopted habits over 180 days without professional guidance; and (ii) in perspective whether flossing provides additional benefits to toothbrushing on gingival health. MATERIALS AND METHODS: Seventy-five adult subjects showing approximately 40% proximal gingival bleeding were randomized to receive OHt (1 session weekly over 8 weeks) using toothbrush and dental floss or toothbrush alone. The subjects were then followed over 180 days without professional guidance. Primary outcomes were mean interproximal Gingival Index (GI) and GI = 2 (gingival bleeding). Mixed linear models were used for the comparison between groups (p < 0.05). RESULTS: 68 subjects received OHt, 48 subjects completed the 180-day follow-up. Subjects maintained adequate oral hygiene routines. Besides a reduction in gingival inflammation, no alterations in gingival status were observed among groups, subjects additionally instructed to use dental floss showing a mean interproximal GI = 2 of 12.8 ± 2.5 compared with 19.8 ± 2.2 for subjects limited to tooth brushing alone. CONCLUSIONS: OHt intensive training promotes gingival health and maintenance lasting at least 6 months without professional supervision reinforcing important principles: (i) dental health professionals should dedicate time training and motivating their patients to reach adequate self-performed plaque control; and (ii) the adjunctive use of dental floss appears essential to reduce interproximal gingival inflammation in subjects with intact interdental papillae. CLINICAL RELEVANCE: Dentists need to invest time in training/motivating/engage their patients to achieve adequate OH; adjunct flossing in subjects with papilla filling the interdental space appears essential to reach and maintain gingival health. CLINICALTRIALS: GOV : (53831716.5.0000.5346). TRIAL REGISTRATION: The protocol registration was filed May 9, 2018 (# 538,311,716.5.0000.5346) on ClinicalTrials.gov. An NCT number (NCT04909840) was generated upon completed registration.

Self-determined use of provided powered oral hygiene devices leads to improved gingival health after 1 year: a longitudinal clinical trial.

PURPOSE: Our study aimed to evaluate the long-term concordance and acceptance when using powered devices for everyday oral hygiene routine and gingival health in patients showing papillary bleeding. PATIENTS AND METHODS: Thirty-one participants were recruited at the dental clinic of the University Hospital of Cologne, Germany, over a 6-week duration. At baseline, a standard dental check-up was performed, including oral hygiene indices and documentation of oral hygiene devices used. The study consisted of two consecutive phases: the first (motivational trial) was designed to prove the effectiveness and safety of a microdroplet device and a powered toothbrush compared to dental floss and a manual toothbrush over a period of 4 weeks. The second (observational) phase began with all participants receiving the powered oral homecare devices. Participants were able to use their oral hygiene measures of choice over an unsupervised period of 1 year. All participants were then rescheduled for a routine dental check-up, where oral hygiene indices and oral hygiene devices used were reevaluated. RESULTS: After 1 year, 93.3% of participants stated they performed interdental cleaning on a regular basis (baseline 60.0%). The percentage using a powered toothbrush increased from 41.9% (baseline) to 90.0% after 1 year. Oral hygiene parameters had improved after both the motivational trial and observational phases compared to baseline (papillary bleeding index p = .000; Rustogi Modified Navy Plaque Index p < .05; Quigley-Hein Index p = .000). CONCLUSION: In the long term, participants preferred using powered oral hygiene devices over the gold standard dental floss and manual toothbrush. Improved oral hygiene parameters after 1 year may indicate implementation of newly acquired oral-hygiene skills during the 4-week instruction phase.

Quantitative analysis of the effects of brushing, flossing, and mouthrinsing on supragingival and subgingival plaque microbiota: 12-week clinical trial.

BACKGROUND: Translational microbiome research using next-generation DNA sequencing is challenging due to the semi-qualitative nature of relative abundance data. A novel method for quantitative analysis was applied in this 12-week clinical trial to understand the mechanical vs. chemotherapeutic actions of brushing, flossing, and mouthrinsing against the supragingival dental plaque microbiome. Enumeration of viable bacteria using vPCR was also applied on supragingival plaque for validation and on subgingival plaque to evaluate interventional effects below the gingival margin. METHODS: Subjects with gingivitis were enrolled in a single center, examiner-blind, virtually supervised, parallel group controlled clinical trial. Subjects with gingivitis were randomized into brushing only (B); brushing and flossing (BF); brushing and rinsing with Listerine® Cool Mint® Antiseptic (BA); brushing and rinsing with Listerine® Cool Mint® Zero (BZ); or brushing, flossing, and rinsing with Listerine® Cool Mint® Zero (BFZ). All subjects brushed twice daily for 1 min with a sodium monofluorophosphate toothpaste and a soft-bristled toothbrush. Subjects who flossed used unflavored waxed dental floss once daily. Subjects assigned to mouthrinses rinsed twice daily. Plaque specimens were collected at the baseline visit and after 4 and 12 weeks of intervention. Bacterial cell number quantification was achieved by adding reference amounts of DNA controls to plaque samples prior to DNA extraction, followed by shallow shotgun metagenome sequencing. RESULTS: 286 subjects completed the trial. The metagenomic data for supragingival plaque showed significant reductions in Shannon-Weaver diversity, species richness, and total and categorical bacterial abundances (commensal, gingivitis, and malodor) after 4 and 12 weeks for the BA, BZ, and BFZ groups compared to the B group, while no significant differences were observed between the B and BF groups. Supragingival plaque vPCR further validated these results, and subgingival plaque vPCR demonstrated significant efficacy for the BFZ intervention only. CONCLUSIONS: This publication reports on a successful application of a quantitative method of microbiome analysis in a clinical trial demonstrating the sustained and superior efficacy of essential oil mouthrinses at controlling dental plaque compared to mechanical methods. The quantitative microbiological data in this trial also reinforce the safety and mechanism of action of EO mouthrinses against plaque microbial ecology and highlights the importance of elevating EO mouthrinsing as an integral part of an oral hygiene regimen. TRIAL REGISTRATION: The trial was registered on ClinicalTrials.gov on 31/10/2022. The registration number is NCT05600231.

A Randomized, Parallel Design Study to Evaluate the Effects of Different Oral Cleaning Modalities on Gingivitis and Plaque After a 6-Week Period of Home Use.

The study objective was to evaluate the effect of different interdental oral cleaning modalities on gingivitis and plaque following a 6-week period of home use. This was a randomized, parallel, examiner-blinded study. Study subjects were routine manual toothbrush (MTB) users with moderate to severe gingivitis, aged 18 to 65 years. Subjects were required to have a gingival bleeding score of ≥1 on at least 50 gingival sites per the Gingival Bleeding Index (GBI) and to have a minimum average plaque score of ≥0.6 per the Rustogi Modified Navy Plaque Index (RMNPI) following a 3- to 6-hour plaque accumulation period. Subjects were randomly assigned to one of four groups based on the oral care cleaning modality: (1) NON group: MTB alone, (2) FLS group: MTB plus string floss, (3) MPF group: MTB plus a Philips® Sonicare® Power Flosser with the Quad Stream nozzle, or (4) PPF group: Philips Sonicare power toothbrush plus the power flosser. Safety and efficacy measures (Modified Gingival Index [MGI], GBI, and RMNPI) were assessed at baseline, 2 weeks, and 6 weeks. The primary efficacy endpoint was the reduction in gingival inflammation from baseline to week 6 as measured by the MGI. A total of 260 subjects were randomized and 256 subjects completed the study. The adjusted mean percent reduction in gingival inflammation from baseline to week 6 was 14.90% for the NON group, 13.16% for the FLS group, 33.51% for the MPF group, and 49.30% for the PPF group. Pairwise comparisons indicated that both the PPF and MPF groups were statistically significantly different from both the NON and FLS groups. In conclusion, use of either the Philips Sonicare power toothbrush with the Philips Sonicare Power Flosser or an MTB with the Philips Sonicare Power Flosser was statistically superior to an MTB alone and an MTB used with string floss in reducing gingival inflammation following 6 weeks of home use.

A Randomized, Parallel Design Study to Compare the Effects of Two Different Interdental Cleaning Modalities on Gingivitis and Plaque After a 4-Week Period of Home Use.

The study objective was to evaluate the effect of two different interdental oral cleaning modalities on gingivitis and plaque following a 4-week period of home use. This was a randomized, parallel, single-blinded study. Subjects were routine manual toothbrush (MTB) users with moderate to severe gingivitis, aged 18 to 65 years. Subjects were required at baseline to have a gingival bleeding score of ≥1 on at least 50 gingival sites per the Gingival Bleeding Index (GBI) and to have an overall plaque score of ≥0.6 per the Rustogi Modified Navy Plaque Index (RMNPI) following a 3- to 6-hour plaque accumulation period. Subjects were randomly assigned to one of three groups based on the oral care cleaning modalities: (1) NON group: MTB alone, (2) IDB group: MTB plus an interdental brush, or (3) MPF group: MTB plus a Philips® Sonicare® Power Flosser with the Quad Stream nozzle. All subjects used the MTB with fluoride toothpaste. Efficacy measures (Modified Gingival Index [MGI], GBI, and RMNPI) and safety were assessed at baseline, 2 weeks, and 4 weeks. The primary efficacy endpoint was the reduction in gingival inflammation from baseline to week 4 as measured by the MGI. A total of 189 subjects were randomized and 186 completed the study. The adjusted mean percent reduction in gingival inflammation from baseline to week 4 was 2.80% for the NON group, 11.32% for the IDB group, and 20.87% for the MPF group. The differences between the MPF group and the NON and IDB groups were statistically significant (.0001). In conclusion, use of the MTB with the Philips Sonicare Power Flosser showed statistically significant benefits compared to an MTB alone and an MTB used with an interdental brush in reducing gingival inflammation following 4 weeks of home use.

A Randomized, Parallel Design Study to Compare the Effects of Different Interdental Cleaning Modalities on Gingivitis and Plaque After a 6-Week Period of Home Use.

The objective of this study was to evaluate the effect of different interdental oral cleaning modalities on gingivitis and plaque following a 6-week period of home use. This was a randomized, four-arm, parallel design clinical trial. Study subjects were manual toothbrush (MTB) users with moderate to severe gingivitis, aged 18 to 65 years. Subjects were required at baseline to have a gingival bleeding score of ≥1 on at least 50 gingival sites per the Gingival Bleeding Index (GBI) and to have an overall plaque score of ≥0.6 per the Rustogi Modified Navy Plaque Index (RMNPI) following a 3- to 6-hour plaque accumulation period. Subjects were randomly assigned to use one of four oral care cleaning modalities: (1) NON group: MTB alone, (2) FLS group: MTB plus string floss, (3) IDB group: MTB plus an interdental brush, or (4) CPF group: MTB plus the Philips® Sonicare® Cordless Power Flosser with the Quad Stream nozzle. Efficacy measures (Modified Gingival Index [MGI], GBI, and RMNPI) and safety were assessed at baseline, 2 weeks, and 6 weeks. The primary efficacy endpoint was the reduction in gingival inflammation from baseline to week 6 as measured by the MGI. Of the 372 subjects randomized in the study, 364 completed a post-baseline MGI evaluation and were included in the analyses. The adjusted mean percent reduction in gingival inflammation from baseline to week 6 was -2.10% for the NON group, 2.82% for the FLS group, 2.60% for the IDB group, and 29.10% for the CPF group. Pairwise comparisons indicated that the CPF group was statistically significantly different from the NON, FLS, and IDB groups (.0001). In conclusion, adjunctive use of the Philips Sonicare Cordless Power Flosser with the Quad Stream nozzle and an MTB showed statistically better results in term of reducing gingival inflammation following 6 weeks of home use when compared to an MTB alone, an MTB used with string floss, and an MTB used with an interdental brush.

Power Flossing Removes Biofilm From Model Periodontal Pockets In Vitro and Shifts the Microbiome During Biofilm Regrowth.

The Philips® Sonicare® Power Flosser (PSPF) is highly effective in reducing gum disease. Next to effective supragingival cleaning, this may be partially driven by subgingival cleaning. This in vitro study aimed to assess the effectiveness of the PSPF in removing biofilm from a model periodontal pocket up to 6 mm deep and to investigate the taxonomic composition of biofilm regrown after use of the PSPF.

Creating Behavior Change for Interdental Biofi lm Disruption: Oral Irrigation as a Solution to Increasing Patient Compliance.

Interdental cleaning is critical to maintaining oral health, preventing dental issues, and promoting overall well-being. However, many patients either struggle with consistently following recommended interdental care routines or have poor technique when complying with recommendations. Addressing this problem requires a multifaceted approach comprised of tailored patient education and patient-clinician partnership to provide both an effective interdental cleaning tool and an accessible method for the patient to implement the modified interdental habit into their routine. The aim of this article is to discuss the different modalities for interdental cleaning, how to assess patient candidacy for different interdental cleaning modalities, and behavior-change strategies to promote patient compliance to recommended interdental care.

In Vitro Biofilm Removal From Human Enamel Using a Philips® Sonicare® Power Flosser.

The objective of this in vitro study was to quantify the removal of dental biofilm from human enamel surfaces after treatment with the Philips® Sonicare® Power Flosser. Dental biofilms were grown from pooled human saliva on human enamel disks for 4 days, according to an established academic model.* The biofilms (n = 6) were treated with the Philips Sonicare Power Flosser for 3 seconds using the Quad Stream nozzle. To quantify the number of bacteria before treatment, the biofilm volume was measured using optical coherence tomography (OCT) and the bacterial cell density was determined from untreated control samples (n = 6) using confocal laser scanning microscopy (CLSM). After treatment the number of remaining bacteria were counted using CLSM. Additionally, scanning electron microscope (SEM) images were recorded. While before treatment 0.2-mm thick dense biofilms were present, after treatment only scattered groups of bacteria remained (Figure 1 through Figure 4). Quantitative analysis showed 99.96% removal for the Quad Stream nozzle. The Philips Sonicare Power Flosser oral irrigator with Quad Stream nozzle removed over 99.9% of the bacteria in this established laboratory model of dental biofilm.

The effectiveness of water jet flossing and interdental flossing for oral hygiene in orthodontic patients with fixed appliances: a randomized clinical trial.

BACKGROUND: Orthodontic treatment presents challenges with plaque accumulation around brackets, archwires, and elastics, leading to retained plaque and gingival inflammation. Conventional toothbrushing may not be enough, requiring additional oral hygiene aids like interproximal brushes, dental flosses, and water flossers. Limited research exists on comparing water flossing and interdental flossing in orthodontic patients. Therefore, this study aims to assess their effectiveness in maintaining oral hygiene during active orthodontic treatment. METHODS: A single-blind, randomized, parallel clinical study recruited orthodontic patients with full-mouth brackets and archwires. Thirty participants were randomly assigned to either water jet flossing or interdental flossing groups. All participants were instructed to brush twice daily with a provided toothbrush and toothpaste and use the assigned intervention once daily at night. Clinical measures, including the Gingival Bleeding Index (BI), Plaque Index (PI), and Gingival Index (GI), were recorded at baseline and day 14. Descriptive statistics and statistical tests were performed using SPSS software. RESULTS: The water jet flossing group demonstrated a slightly higher, albeit non-significant, benefit in plaque removal (median difference of 6.79%%, P = 0.279) and bleeding reduction (median difference of 5.21%%, P = 0.172) compared to the interdental flossing group after two weeks. Both groups showed significant reductions in gingival bleeding index and plaque index from baseline to the 2-week follow-up. The interdental flossing group had median mean percentage differences of 16.13%% (plaque index) and 23.57% (gingival bleeding index), while the water jet flossing group had median percentage differences of 21.87% (plaque index) and 32.29% (gingival bleeding index). No significant changes in gingival index grades were observed in either group. CONCLUSION: Both water jet flossing and interdental flossing were effective in reducing plaque accumulation and gingival bleeding among orthodontic patients. While no significant differences were found between the two methods, water jet flossing showed a potential advantage. Further research is needed to validate its effectiveness, assess long-term impact, and understand its benefits for orthodontic patients.

New design of interdental rubber picks - does the archimedean screw design bring an improvement for experimental cleaning efficacy and force?

BACKGROUND: Up to date, interdental brushes (IDB) are the first choice for interdental cleaning because of their cleaning efficacy. Cylindrical ones must be selected individually according to the size/morphology of the interdental area (IDR), whereas conical ones cover a larger variability of IDR. However, there is a trend on the part of patients towards interdental rubber picks (IRP) which are in general conically shaped, and which seem to be linked with lower cleaning efficacy. A new IRP with an Archimedes´ screw design was developed to overcome this limitation. Therefore, the in vitro study aimed to measure the experimental cleaning efficacy (ECE) and force (ECF) during interdental use of IDBs versus the new IRP type. METHODS: Three IRPs with different tapers (PHB angled: 0.039, PHB straight S: 0.027, Vitis straight M: 0.045; all Flexipicks, Dentaid, Cerdanyola del Vallès, Spain) were compared to one IDB (Interprox micro PHD 0.9, Dentaid, Cerdanyola del Vallès, Spain). IDR were reproduced by a 3D-printer (Form2, Formlabs Sommerville, MA, USA) according to human teeth and matched to equivalent pairs (isosceles triangle, concave, convex) in three different diameters (1.0 mm,1.1 mm,1.3 mm). Covered with simulated biofilm, pre-/ post-brushing situations of IDR (standardized, computer-aided ten cycles) were photographed and quantified by digital image subtraction to calculate ECE [%]. ECF were registered with a load cell [N]. Statistically significant differences were detected using the Mann-Whitney-U-test and the Kruskal-Wallis-test with Bonferroni correction for multiple testing. RESULTS: Overall, the ECE (mean ± SD) was higher for IDB micro 0.9 (45.95 ± 11.34%, p < 0.001) compared to all IRPs (PHB angled: 25.37 ± 15.29%; PHB straight: 22.28 ± 16.75%; Vitis straight: 25.24 ± 12.21%; p ≤ 0.001), whereat best ECE was achieved in isosceles triangle IDR of 1.0-1.1 mm (IDB micro 0.9: 70.7 ± 7.7%; PHB angled S: 57.30 ± 4.43%; p < 0.001). The highest ECF occurred for Vitis straight M with 2.11 ± 0.46 N, while IDB micro 0.9 showed lowest ECF values (0.64 ± 0.14 N; p < 0.001). CONCLUSIONS: IRP with an Archimedes´ screw design and a higher taper were associated with advanced ECE but also higher ECF, nevertheless, ECE didn't reach the cleaning efficacy of conventional IDBs.

Evaluation of the efficacy of inter-dental brush and dental floss for peri-implant mucositis: A crossover randomized clinical trial.

OBJECTIVES: To evaluate the most effective method for mechanical inter-dental plaque removal between inter-dental brushes (IDB) and dental floss (DF), in addition to toothbrushing in patients affected by peri-implant mucositis (PIM); to identify possible factors related to the patient or to the single implant-supported element that could influence plaque accumulation and inflammation of peri-implant tissues. METHODS: Forty patients with PIM were recruited. They were randomly assigned to two different groups depending on inter-dental device used (IDB or DF). At baseline (T0), interproximal area (IA), interproximal emergence angle of the implant crown (A°) and manual dexterity (evaluated with Purdue Pegboard) have been recorded. At 14 days (T1), the inter-dental cleaning devices have been inverted between groups. After 14 days (T2), the Plaque Index (PI) and Gingival Index (GI) have been recorded. A questionnaire has been submitted to a patient for the analysis of preferences at T0, T1 and T2. RESULTS: Both inter-dental cleaning devices were effective in reducing PI and GI in the inter-dental area after 14 days of use. GI reduction was influenced by manual dexterity of the dominant hand. No significant differences were found for PI and GI at the variation of IA and A°. CONCLUSION: IDB was the most effective method for inter-dental plaque removal in all subjects regardless of their manual dexterity. DF seems to be more effective than IDB only in subjects with good dexterity.

Efficacy of flossing and mouth rinsing regimens on plaque and gingivitis: a randomized clinical trial.

BACKGROUND: To investigate the effects of combinations of mechanical (brushing and flossing) and chemotherapeutic regimens which included essential oils (EO) non-alcohol and alcohol-containing mouthrinses compared to brushing only in the prevention and reduction of plaque, gingivitis, and gingival bleeding. METHODS: This was a randomized, virtually supervised, examiner blind, controlled clinical trial. Following informed consent and screening, subjects (N = 270) with gingivitis were randomly assigned to one of the following regimens: (1) Brush Only (B, n = 54); (2) Brush/Rinse (EO alcohol-containing mouthrinse) (BA, n = 54); (3) Brush/Rinse (EO non-alcohol containing mouthrinse) (BZ, n = 54); (4) Brush/Floss (BF, n = 54); (5) Brush/Floss/Rinse (EO non-alcohol containing mouthrinse) (BFZ, n = 54). Unflavored waxed dental floss (REACH unflavored waxed dental floss), and fluoridated toothpaste (Colgate Cavity Protection) were used. Examinations included oral hard and soft tissue, plaque, gingivitis, gingival bleeding, probing depth and bleeding on probing. RESULTS: After 12 weeks, both BA and BZ and the BFZ group were superior in reducing interproximal plaque (30.8%, 18.2%, 16.0%, respectively), gingivitis (39.0%, 36.9%, 36.1%, respectively), and bleeding (67.8%, 73.6%, 79.8%, respectively) compared to B. The BF group did not provide significant reductions in interproximal plaque but did reduce interproximal gingivitis (5.1%, p = 0.041) at Week 4 and bleeding at Weeks 4 and 12 (34.6%, 31.4%, p < 0.001 respectively) compared to B. The BFZ group did not significantly reduce interproximal plaque, gingivitis or bleeding compared to BZ. CONCLUSIONS: This study demonstrated that the addition of EO non-alcohol containing mouthrinse to the manual toothbrushing and flossing regimen further reduces plaque, gingivitis and bleeding showing that addition of EO mouthrinses (alcohol or non-alcohol containing) to the oral hygiene regimen provides sustained reductions in plaque to help maintain gingival health after a dental prophylaxis. Dental professional recommendation of the addition of an EO non-alcohol containing mouthrinse to daily oral hygiene routines of brushing or brushing and flossing should be considered to aid supragingival plaque control and improve gingivitis prevention. STUDY REGISTRY NUMBER: NCT05600231.

Powered versus manual toothbrushes for plaque removal and gingival health amongst 55 and older individuals: A systematic review and meta-analysis.

OBJECTIVE: To compare manual and powered toothbrushes in older adults and to culminate available clinical evidence concerning efficiency with respect to plaque removal and reduced gingivitis. BACKGROUND: Manual dexterity decreases with age, negatively impacting daily activities, including oral hygiene practices. Effective plaque control in this age group is directly related to nutrition and overall health. Therefore, developing oral health interventions tailored to the ageing population is essential. MATERIAL AND METHODS: This systematic review was registered with PROSPERO (Registration No. CRD42023415876). Five electronic databases were searched to identify randomized controlled trials published from inception until March 2023. The risk of bias was assessed using the Cochrane Risk of Bias Tool. Meta-analyses were also performed for gingival, plaque, and bleeding indices. RESULTS: A total of 2118 records were identified, and six eligible publications were retrieved. Comparison of Plaque Indices between powered and manual toothbrushes showed a Standard mean difference (SMD) of -0.10; 95% CI [-0.37, 0.18] (p = .38). Comparison of the gingival index and bleeding index between powered and manual toothbrushes showed an SMD of -0.28; 95% CI [-0.72, 0.16] (p = .22) and SMD of -0.03 [-0.38, 0.32] (p = .84), respectively. CONCLUSION: According to the available literature, this study suggests the need for more streamlined research to support the superiority of either powered or manual toothbrushes in improving oral health (as measured by the indices) among the older population. The results will hence have significant reverberations for older adults looking to improve their oral hygiene practices.
