Agrawal, SK, Dahal, S, Bhumika, TV, Nair, NS
Journal of Nepal Health Research Council. 2019;(41):364-371
Abstract
Toothbrushes play an essential role in personal oral hygiene by effective plaque removal.However, they get heavily contaminated by bacteria, viruses, yeasts, and fungi which may originate from the oral cavity after every use as well as from the environment where they are stored. This systematic review was conducted to identify various decontamination interventions attempted scientifically and it summarizes the efficacy of each. Meta-analysis illustrated that the use of Ultra-violet rays and Microwave had a significant effect on reduction of the microbial count of a used toothbrush with a mean difference of -2.61 and CI (-4.66,-0.76) with I2=98%. When compared with non-active treatment group, the natural agents (garlic, green tree and tea-tree oil) proved to sterilize the toothbrushes effectively with mean difference of -483.34, CI (-914.79, -51.88) and I2=100%.In contrast, chlorhexidine showed the insignificant result with a mean difference of -347.55 and CI (-951.90, 256.80) with I2=100%. The evidence from this review suggests that decontaminating toothbrush reduces bacterial load. Toothbrushes exposed to radiation and natural agents proved to sanitize them effectively but chlorhexidine rendered insignificant results. Keywords: Chemical agent; disinfection; radiation; microbial load; natural agent; toothbrush.

International journal of dental hygiene. 2018;(4):535-540
Abstract
OBJECTIVE The chewing sticks are widely used in many regions of Asia and Africa as a traditional tool to maintain oral hygiene. Salvadora persica L. (S. persica), also known as Arak or Miswak, a member of the salvadoraceae family. Chewing sticks, made up from S. persica, have chemical antibacterial properties and mechanical effects. The study aimed to investigate possible chemical effects of S. persica on dental plaque, sub-gingival microbiota and gingival inflammation. In order to achieve this, we inactivated some sticks through boiling to be used as inactive, but mechanically comparable control sticks. METHODS In a double-blinded crossover trial, 24 patients with mild-to-moderate periodontitis were randomly allocated to use either fresh activated Miswak or inactivated Miswak for 3-week period. Plaque index (PI), gingival index (GI), visual plaque index (VPI) and bleeding on probing (BOP) were evaluated before and immediately following the experimental period. Sub-gingival plaque samples were analysed using DNA-DNA hybridization technique. The study was repeated with the participants switching the type of Miswak they used after a 7-week of "washout" period. RESULTS There were no significant differences in the microflora after using active and inactive Miswak. Sixteen species of bacteria showed an increase (P < 0.05) after the usage of inactive Miswak, as compared to pretreatment values. No species showed a similar change after the use of active Miswak. There were no significant differences between active and inactive Miswak regarding the registered clinical variables. CONCLUSION This study has not shown any clinical effect of the chemically active Miswak, but there was a tendency towards an effect on the microflora.

Community dental health. 2017;(4):208-225
Abstract
OBJECTIVE In this article we report the findings of a scoping review that aimed to identify and summarise the range of programs and guidelines available for toothbrushing programs in schools and early childhood settings. Dental caries is one of the most common preventable diseases affecting children worldwide. Untreated caries can impact on child health and wellbeing, development, socialisation and school attendance. Supervised toothbrushing programs in schools and other early childhood settings can be effective in improving the oral health of young children. There is limited understanding of the salient issues to consider when developing such programs or how they are best implemented in real world settings. METHODS A scoping review methodology was utilised to provide a summary of the guidelines and programs available. Key search terms were developed, mapped and utilised to identify guidelines and programs across 6 databases and key search engines. RESULTS We located 26 programs and guidelines that met the inclusion and exclusion criteria for the review. These were collated and summarised across key countries and critical aspects of program development and implementation were identified. Toothbrush type and storage, toothpaste strength and method of dispensing, toothbrush storage, staff training and parental consent are key considerations that varied widely. CONCLUSIONS AND RECOMMENDATIONS Guidelines for supervised toothbrushing programs vary within and across countries due to differences in water fluoridation and availability of low fluoride toothpastes. The results of this review provide critical information to be considered when establishing and implementing toothbrushing programs in these settings.

Abstract
AIM: This was to compare the salivary fluoride levels following tooth brushing with amine fluoride toothpastes containing three different concentrations of F (250 ppm F, 500 ppm F and 1250 ppm F) and to evaluate the effect of rinsing with water on the oral fluoride levels up to 90 min. METHODS A double blind randomised six-arm crossover study was conducted with 32 child participants. Patients were divided into two groups depending on their caries experience with caries-free group (n = 17, mean age = 72.9 months) and caries-prone group (n = 15, mean age = 69.6 months, mean dmfs = 12.3). Each participant brushed their teeth with a smear of dentifrice containing (250 ppm, 500 ppm and 1250 ppm F toothpastes) for 60 s. After spitting out the dentifrice/saliva slurry, participants either rinsed with water or did not rinse at all. Samples of whole mixed unstimulated saliva were collected at 0 (baseline), 1, 15, 30, 45, 60 and 90 mins post-brushing/rinsing. RESULTS After completing the study on residual fluoride concentration it was found that caries was not a significant variable (p = 0.567) while every other variable was (all p values <0.001). Time, toothpaste F concentration and rinse had significant effects (p < 0.001). In general, higher residual salivary F concentrations were found with increased F concentration in toothpastes and when no rinsing was performed after brushing. CONCLUSION The results of this study support the current recommendation of using toothpastes with >1000 ppm F concentration in children with an increased caries risk in addition to spitting excess toothpaste with no rinsing following brushing.

Community dental health. 2016;(3):213-217
Abstract
OBJECTIVE To investigate the impact of an integrated oral health promotion intervention, within the Syrian national immunisation programme, which provided free preventive dental health products, without health workers' counselling, on one-year-old infants' tooth-brushing and bottle-feeding termination practices. RESEARCH DESIGN a randomised controlled parallel-group trial. SETTING A maternal and child health centre in Sweida city, Syria. PARTICIPANTS 92 mothers of one-year-old infants, attending an infant vaccination clinic, were allocated into three groups: Test, Control One and Control Two. INTERVENTIONS The Test group received an oral health promotion package including an infant oral health pamphlet, a baby toothbrush, fluoride toothpaste (1,000 mg/L) and a trainer cup, without health workers' counselling. Control One received only the pamphlet, whilst Control Two received no intervention. MAIN OUTCOME MEASURES after one month, the presence of old plaque on infants' primary teeth was checked, to assess tooth-brushing behaviour. Also, a mothers' self-completed questionnaire was administered to assess bottle-feeding use. RESULTS The response rate was 100% and the attrition rate was zero. There were differences in tooth-brushing and bottle-feeding termination practices between the three groups (P⟩0.001). Infants in the Test group were less likely to have old plaque and more likely to stop bottle-feeding than their counterparts in the two control groups. There were no differences in the abovementioned outcomes between the two control groups. CONCLUSIONS Providing free preventive dental health products, without health worker's counselling, in an integrated oral health promotion intervention, was an effective measure to promote infants' tooth-brushing and bottle-feeding termination practices. These findings should be supported by long-term follow up studies.

Abstract
OBJECTIVE To compare the efficacy of an oscillating-rotating power toothbrush with a novel brush head incorporating angled CrissCross bristles (Oral-B Triumph with SmartGuide with Oral-B CrossAction brush head) versus a sonic toothbrush (Sonicare DiamondClean) for plaque and gingivitis reduction over a six-week period. METHODS This was a single-center, randomized, examiner-blind, two-treatment, parallel group study involving 65 subjects per group. Subjects presenting with mild-to-moderate gingivitis at Baseline were randomly assigned to either the oscillating-rotating brush or the sonic brush. They were instructed to use their assigned toothbrush and a standard fluoride dentifrice for two minutes twice daily at home for six weeks. Gingivitis and plaque were assessed at Baseline and Week 6 using the Modified Gingival Index (MGI), Gingival Bleeding Index (GBI), and Rustogi Modified Navy Plaque Index (RMNPI). Data were analyzed using an Analysis of Covariance (ANCOVA), with baseline as the covariate. Subjects also completed a consumer perception questionnaire to evaluate their brushing experience. RESULTS One-hundred and thirty subjects were enrolled in the study and randomized to treatment. Sixty-four subjects per group completed the trial. Both brushes produced statistically significant reductions in gingivitis and plaque measures at Week 6 relative to Baseline (p < 0.001 for all). The oscillating-rotating brush with the novel brush head demonstrated statistically significantly greater reductions in all gingivitis and plaque measures compared to the sonic toothbrush. The benefits for the oscillating-rotating brush over the sonic brush were 32.6% for gingivitis, 35.4% for gingival bleeding, 32% for number of bleeding sites, 22% for whole mouth plaque, 24.2% for gingival margin plaque, and 33.3% for approximal plaque (p < or = 0.001 for all measures except gingival margin plaque, where p = 0.018). Analysis of the consumer perception questionnaire results showed subjects using the oscillating-rotating brush rated it higher for overall use experience and key attributes related to cleaning, gentleness, and brush head shape/size versus subjects in the sonic brush group. There were no adverse events reported or observed for either brush. CONCLUSION This six-week randomized, examiner-blind, comparative clinical study showed the oscillating-rotating toothbrush, with a novel brush head incorporating angled CrissCross bristles, was significantly better than an advanced sonic power toothbrush at reducing gingival inflammation and bleeding, as well as reducing whole mouth plaque, plaque along the gumline, and in the approximal regions.

Sonesson, M, Twetman, S, Bondemark, L
European journal of orthodontics. 2014;(6):678-82
Abstract
OBJECTIVE To evaluate the effectiveness of daily tooth brushing with high-fluoride toothpaste on white spot lesion (WSL) formation in adolescents during treatment with fixed orthodontic appliances (FOA). MATERIALS AND METHODS Four hundred and twenty-four healthy 11- to 16-year-old patients, referred to five Orthodontic Specialist Clinics, were randomized to use either toothpaste containing 5000 ppm fluoride or regular toothpaste with 1450 ppm fluoride. To be eligible for inclusion, the patients had to be scheduled for bimaxillary treatment with FOA for an expected duration of at least 1 year. The primary and secondary outcome measures were prevalence and incidence of WSL, as registered from digital photos of the maxillary incisors, canines, and premolars taken before onset and immediately after debonding. The photos were evaluated separately by two blinded and calibrated clinicians using a 4-step score. A random sample of 50 cases was reassessed to check intra- and interexaminer reliability (Kappa = 0.70; 0.74). RESULTS The use of high-fluoride toothpaste resulted in fewer WSL (P = 0.042) with a prevented fraction of 32%. The lateral incisor was most commonly affected in both groups. CONCLUSION To prevent WSL during treatment of FOA, daily use of high-fluoride toothpaste may be recommended.

Abstract
While toothpaste F(-) concentration and rinsing regimen have well-characterised impacts on fluoride's effectiveness, other aspects of brushing regimen have much less well-established effects, in particular, dentifrice quantity and brushing duration. An in vivo study (n = 42) of oral fluoride delivery (i.e. oral disposition post-brushing), and retention (i.e. concentration of F(-) in saliva post-brushing, a known efficacy predictor), was performed to compare effects observed with those of dentifrice F(-) concentration and rinsing regimen. Subjects brushed with a NaF-silica dentifrice (Aquafresh Advanced, 1,150 ppm F(-) ) or a control dentifrice (250 ppm F(-) , same base), for 45, 60, 120 or 180 seconds with 0.5 or 1.5 g dentifrice, and rinsed with 15 ml water once or three times in a cross-over design. The F(-) concentration was measured in post-brushing expectorate, rinse and toothbrush washing samples, and in saliva between 5-120 minutes after brushing. Using 1.5 g versus 0.5 g dentifrice increased F(-) in all samples: oral retention of F(-) was almost doubled by this increase. Increasing duration of brushing had more complex effects. The amount of F(-) in the expectorate increased but decreased in both rinse and toothbrush washing samples. Oral F(-) retention increased, but only in the period 30-120 minutes after brushing. Over the ranges investigated, the order of importance on oral F(-) retention was: dentifrice F(-) concentration > quantity > rinsing regimen > brushing duration. Hence, increasing dentifrice quantity and, to a lesser extent, the duration of brushing, can elevate oral fluoride post-brushing. Evidence is accumulating that the importance of these variables to fluoride efficacy may have been underestimated.

After-brush rinsing protocols, frequency of toothpaste use: fluoride and other active ingredients.
Parnell, C, O'Mullane, D
Monographs in oral science. 2013;:140-53
Abstract
The intra-oral retention or substantivity of active ingredients in toothpastes is important for their effectiveness, and this is influenced by product-related and user-related factors. Product-related factors include the formulation and the compatibility of active and other agents in the toothpaste and the concentration of the active ingredient. User-related factors include biological aspects such as salivary flow and salivary clearance, and behavioural aspects, such as frequency and duration of brushing, amount of toothpaste used and post-brushing rinsing behaviour. To date, product-related factors have dominated the research agenda for toothpastes, but user-related factors have the potential to significantly enhance or reduce the effectiveness of toothpaste. In this chapter, we will focus on two of the user-related factors that have been most widely studied: (1) frequency of toothbrushing and (2) post-brushing rinsing behaviour. We will then provide an overview of how evidence on these two behaviours has been used to produce guidance both for the profession and for the public, and make suggestions for the future direction of research in this area.

Tomás, I, Diz, P, Tobías, A, Scully, C, Donos, N
Journal of clinical periodontology. 2012;(3):213-28
Abstract
AIM: The aim of this study was to investigate the robustness of the observations on the influence of oral hygiene, gingival and periodontal status on the development of bacteraemia from everyday oral activities (B-EOA), analysing its prevalence, duration, magnitude and bacterial diversity. MATERIAL AND METHODS This systematic review/meta-analysis complies with PRISMA reporting guidelines. MEDLINE-PubMed, the Cochrane Library and Embase were explored for detecting studies on B-EOA. RESULTS There were 290 potentially eligible articles, of which 12 article on B-EOA fulfilled the inclusion criteria and were processed for data extraction (seven on toothbrushing, one on dental flossing and four on chewing). Evaluating the influence of plaque and gingival indices on the prevalence of bacteraemia following toothbrushing, the pooled odds ratios were 2.61 [95% confidence interval (CI) = 1.45-4.69] and 2.77 (95% CI = 1.50-5.11), respectively. None of five studies on bacteraemia following dental flossing and chewing revealed a statistically significant association between oral hygiene, gingival or periodontal status and the development of bacteraemia. CONCLUSIONS Meta-analysis showed that plaque accumulation and gingival inflammation scores significantly increased the prevalence of bacteraemia following toothbrushing. However, systematic review showed no relationship between oral hygiene, gingival and periodontal status and the development of B-chewing, and there is no evidence that gingival and periodontal health status affects B-flossing.
