Meta-Analysis
OBJECTIVES
This systematic review with network meta-analysis synthesises available randomised controlled trials evidence concerning efficacy of self-administered dentifrices for management of dentine hypersensitivity (DH) pain.
STUDY SELECTION
Following systematic review registration (CRD42019154064), three data bases (MEDLINE, Embase, CENTRAL) were searched to December 2022 for parallel randomised controlled trials conducted in adults diagnosed with DH, using at least two recognised stimuli, assessing the short-term efficacy of home-use dentifrice treatment in reducing pain. Thirty-two studies and 4,638 participants were included. A Network meta-analysis (NMA) approach was used to compare relative effectiveness between interventions.
CONCLUSIONS
Twice daily application of self-applied dentifrice containing formulations of stannous, potassium +/- stannous, or arginine can be recommended for the reduction of dentine hypersensitivity pain. There is a need for standardised methodology guideline development to improve the conduct, analysis and reporting of DH clinical studies.
CLINICAL RELEVANCE
This is the first comprehensive NMA to be performed, that follows guidelines for conduct of DH trials to determine the efficacy of self-applied dentifrices for the management of dentine hypersensitivity. Indirect comparisons can be made between formulations that have not been compared to one another in randomised controlled trials.

Meta-Analysis Review
Dental caries is a global oral health problem caused due to localized demineralization of the enamel. Chemical plaque control is used as an adjuvant to mechanical plaque control in removing biofilm, thereby preventing dental caries. In recent times, there has been a renewed interest in nature-based products. This systematic review aimed to analyse the existing literature to compare the effectiveness of herbal and conventional dentifrices on prevention of dental caries. A search was done in the databases of PubMed and Google Scholar in July 2020 for the related topic. A hand search was done from the references of primary studies and other clinical trial registry sites. Randomized control trials, comparative clinical trials, and in vitro studies in which the effectiveness of herbal and conventional dentifrices on prevention of dental caries were included after review by the reviewers. The systematic search revealed a total of thirty-two publications from which ten publications were included. Five studies were clinical studies and five were in vitro studies. All the studies used microbiological analysis for the determination of cariogenic microorganisms in plaque and saliva, whereas one study used pH of plaque and saliva. Among the included studies, all studies had a high risk of bias with level 2 evidence. With the evidence available, it can be concluded that herbal dentifrices and fluoride dentifrices have similar antimicrobial activity against cariogenic microorganisms.

Review
The use of bioactive materials is a recent proposal in the treatment of dentin hypersensitivity (DH) due to the ability to stimulate the neoformation of a barrier on dentin surface. Questions have arisen about the effectiveness of the materials to reduce DH when compared to the control groups (placebo or non-bioactive substance). Thus, the aim of this systematic review was to evaluate the randomized controlled trials in adult patients for DH treatment with a dentifrice containing bioactive glass, applied either at-home or in-office. : The study was registered in PROSPERO and followed PRISMA guidelines. Searches were carried out in four databases (Pubmed/Medline, CENTRAL, Wbb of Science, LILACS) spanning from February 2020 to March 2020, with no language or publication date restrictions. A supplementary hand-search was performed by checking the list of references. The so-called gray literature of the national and international databases for theses and dissertations, as well as unfinished, in progress and unpublished studies were also searched. : After reading the titles and abstracts, articles that were duplicated (74 records) or unrelated to the systematic review (76 records) were excluded. Fifteen studies were evaluated considering seven at low risk of bias, four at high risk and four at moderate risk. The bioactive compounds at low concentrations (2.5-7.5%) can be used as treatment of DH both at-home and in-office.

Review
The aim of this study is to review the potential of strontium-doped nanohydroxyapatite (SrnHAP) as a biomaterial for remineralizing early carious lesions. Publications from 2012 to 2022 were included based on the patient/population, intervention, comparison, and outcomes (PICO) framework, focusing on demineralized enamel treated with strontium-doped nanohydroxyapatite compared to other remineralizing agents, with the primary outcome being remineralization capacity. Electronic databases, namely, PubMed, Cochrane Library, and Google Scholar, were explored from March 31, 2023, to April 10, 2023. Only English language studies were included, while certain research types and studies on bovine teeth were excluded. Bias was assessed using the Cochrane methodology. Five studies were synthesized, all using extracted human maxillary premolars. Four studies focused on remineralizing enamel, while one study focused on remineralizing dentin. Among these studies, comparisons were made between different strontium concentrations and various remineralizing agents such as nanohydroxyapatite (nHAP), Acclaim, casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), and NovaMin. X-ray diffraction analysis was used to examine hydroxyapatite formation, while scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used for characterization. Additionally, one study evaluated the mechanical properties of partially demineralized dentin specimens. This study was registered in the PROSPERO under the ID CRD42023397413 and completed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Meta-Analysis Review
AIM
To evaluate the efficacy of adjunctive therapies in reducing gingivitis and plaque by means of a systematic review of randomized clinical trials (RCTs).
MATERIAL AND METHODS
A search protocol was designed to identify 6-month RCTs that investigated the efficacy of adjuncts to mechanical plaque control on gingivitis and plaque. Following screening, relevant information was extracted, and quality and potential risk of bias were estimated. Mean treatment differences were calculated to obtain standardized mean differences and weighted mean differences (SMD and WMD) as appropriate.
RESULTS
Meta-analyses included 70 studies of adjunctive antiseptics. Compared with mechanical plaque control alone, adjuncts yielded statistically significant reductions in gingival index (n = 72; SMD = -1.268; 95% CI [-1.489; -1.047]; p < .001; I = 96.2%), bleeding (%) (n = 26, WMD=-14.62%; 95% CI [-18.01%; -11.23%]; p < .001; I = 95.1%), plaque index (n = 93, SMD = -1.017; 95% CI [-1.194; -0.840]; p < .001; I = 95.3%) and plaque (%) (n = 23; WMD = -18.20%; 95% CI [-24.00%; -12.50%]; p < .001; I = 96.9%). Mouthrinses resulted in greater reductions in per cent plaque compared with dentifrices (meta-regression, coefficient = 13.80%; 95% CI [2.40%; 25.10%]; p = .020). The antiseptic agents were similarly effective in reducing gingivitis and plaque in patients with dental plaque-induced gingivitis (intact periodontium) or previously treated periodontitis with gingival inflammation.
CONCLUSION
Adjunctive antiseptics in mouthrinses and dentifrices provide statistically significant reductions in gingival, bleeding and plaque indices.

Review
BACKGROUND
Dental caries is one of the most prevailing oral health diseases in children. Recent times have focused on herbal products, because they have minimum or no side effects and are effective in prevention. Licorice is one such product belonging to Glycyrrhiza family used in the form of dentifrice, chewing gums, lollipop, gels, etc., Literature reports about the activity of licorice root extract on the biofilm thereby reducing Streptococcus mutans (SM) count and preventing dental caries in children.
OBJECTIVES
The objective is to assess the effectiveness of licorice in reducing SM count and preventing dental caries in children.
METHODOLOGY
PubMed and Google scholar were searched with search strategies for studies reporting licorice as intervention in children among 3-15 years for preventing dental caries. Only those studies with study design of randomized controlled trials, clinical trials, and comparative studies published between January 1, 2000, and October 31, 2019 were included. Cross references and hand searching for the relevant articles were also conducted.
RESULTS
A preliminary search yielded a total of 31 studies through PubMed and Google scholar. From 31 studies, nine studies were excluded based on the screening through titles. From the remaining 22 articles, six duplicates, four without parameters, six as reviews and case reports and were excluded. Finally, six articles giving ten estimates were included for qualitative synthesis.
CONCLUSION
Licorice extracts proves to be effective as an antimicrobial agent by reducing the count of SM in children. Its action on biofilm limits the fall of pH thereby preventing acidic environment that increases the risk of dental caries. Moreover, licorice in lollipop form is well accepted by children.

Meta-Analysis
Whitening dentifrices (WDs) are widespread and accessible worldwide, claiming to whiten teeth. Therefore, this systematic review aimed to assess the extrinsic stain removal (ESR), the whitening potential, and the adverse effects of WDs. Randomized controlled trials comparing WDs with regular dentifrices (RDs) and other home-based whitening products were searched at NCBI-PubMed, Cochrane-CENTRAL, EBSCO-Host, and clinicaltrials.gov. The studies were screened and had data extracted by two independent researchers. Eligible studies presented outcomes of ESR, color change, and adverse effects, with no restriction of publication date. Data were meta-analyzed using RevMan 5.3, and the level of evidence was rated according to GRADE criteria. Eleven studies (n=1962) assessed reduction of stain area and intensity through Lobene Stain index, with a mean difference (MD) of -0.33 ([-0.41;-0.25]; =0.00001) and -0.34 ([-0.44;-0.25]; =0.00001), respectively. When the modified Lobene Stain index was used (six studies; n=2576), MD was -0.42 ([-0.58;-0.25]; =0.00001) and -0.30 ([-0.39;-0.21]; =0.00001), respectively. Mean color change through shade guide tabs (three studies; n=1322) was -1.80 ([-2.33;-1.26]; =0.00001). All differences were in favor of the WDs, which also produced a risk of adverse effects (RR=1.74; [1.20, 2.52]; =0.003; four studies; n=1322). The comparison of WDs with paint-on gel (two studies; n=58) yielded similar efficacy and adverse effects (>0.05), whereas the comparison of WDs with white strips (two studies; n=87) yielded higher efficacy of the latter (=0.00001) and similar adverse effects (=0.52). The quality of evidence varied from low to moderate. WDs are more effective in reducing extrinsic stain and producing a whitening-like effect in teeth than RDs, although they also produce more adverse effects. Whitening efficacy of WDs is similar to paint-on gel and lower than white strips. Higher-quality evidence demands larger, well-conducted, independent studies.

The Effect of Charcoal-Based Dentifrice and Conventional Whitening Toothpaste on the Color Stability and Surface Roughness of Composite Resin: A Systematic Review of In Vitro Studies.
The objective was to systematically review studies that evaluated the effect of charcoal-based dentifrices (CbDs) and conventional whitening toothpastes (CWTs) on the color stability (CS) and/or surface roughness (SR) of composite resin (CR). The question we focused on was "Do CbD and CWT affect the CS and/or SR of CR?" Indexed databases were searched without language and time restrictions up to and including May 2023 using different keywords. Original experimental studies were included. The risk of bias (RoB) was assessed using the Quality Assessment Tool for In Vitro Studies. Ten in vitro studies performed on CR were included. The number of CR samples assessed ranged between 18 and 200. In one study, CbDs altered the CS and SR of CR, whereas another study showed no difference in changes in the SR and CS of CR when CbDs were compared with CWTs. One study showed that compared with CWTs, CbDs caused changes in the CS of CR but changes in SR were similar between the two dentifrices. One study showed that CbDs and CWTs improved the overall color and enhanced the SR of CR. Three studies had a high RoB, five had a medium RoB, and two had a low RoB. Compared to CWTs, CbDs appeared to affect the CS of CR, but the SR of CR induced by both dentifrices remained consistent. Further well-designed and power-adjusted studies are needed.

Microplastic particles are used as ingredients in personal care products such as face washes, shower gels and toothpastes and form one of the main sources of microplastic pollution, especially in the marine environment. In addition to being a potential pollutant to the environment, the transfer of microplastics to humans can become a severe threat to public health. This systematic review was conceptualized to identify evidence for the presence of and characteristics of microplastics in toothpaste formulations. The PICOS Criteria was used for including studies for the review. Electronic databases of Scopus, Embase, Springer Link, PubMed, Web of Science and Google Scholar were searched, as well as hand and reference searching of the articles was carried out. The articles were screened using the software application, Covidence® and data was extracted. This systematic review showed that toothpastes from China, Vietnam, Myanmar and the UAE, reported no evidence of microplastics and those from Malaysia, Turkey and India reported the presence of microplastics. The shape of the microplastics present in these toothpastes were found to be granular, irregular with opaque appearance and also in the form of fragments and fibers and the percentage weight in grams ranged from 0.2 to 7.24%. Malaysia releases 0.199 trillion microbeads annually from personal care products into the environment and toothpastes in Turkey release an average of 871 million grams of microplastics annually. Similarly, in India, it has been reported that 1.4 billion grams of microplastic particles are emitted annually from toothpaste. The findings of this systematic review provide evidence that toothpastes, at least in some parts of the world, do contain microplastics and that there is a great risk of increase in the addition of microplastics to the environment by the use of toothpaste.

Clinical Oral Investigations Jun 2021To assess whether professional fluoride application (PFA) used in addition to regular fluoride toothpaste (RFT, ≥ 1,000 ppm) is more effective than RFT alone in children. (Meta-Analysis)
Meta-Analysis Review
OBJECTIVE
To assess whether professional fluoride application (PFA) used in addition to regular fluoride toothpaste (RFT, ≥ 1,000 ppm) is more effective than RFT alone in children.
MATERIALS AND METHODS
A systematic search was conducted using the PubMed, Embase, Google Scholar and CENTRAL databases. Randomized controlled trials (RCTs) comparing the effectiveness of RFT + PFA and RFT alone were included. Meta-analyses with random-effects models were performed. The certainty of evidence was assessed using the GRADE approach.
RESULTS
A total of 2,729 records were identified from electronic and manual searches, which were screened by two reviewers independently and in duplicate. Six RCTs (5,034 participants) were included, of which four had high risk of bias and two had unclear risk of bias. The PFA used in all these trials was fluoride varnish (FV). In meta-analyses, no significant difference was observed between participants receiving FV + RFT and RFT alone of d(m/e)fs increment (mean difference (MD) - 0.17, 95% confidence interval (CI) - 0.60 to 0.26, P = 0.43, I = 38%; 6 trials, 5,034 participants, moderate certainty evidence), incidence of caries (risk ratio (RR) 0.91, 95% CI 0.80 to 1.05, P = 0.21, I = 41%; 4 trials, 4,487 participants, moderate certainty evidence) or changes in prevalence of caries (RR 0.89, 95% CI 0.78 to 1.01, P = 0.07, I = 0%, 4 trials, 4,189 participants, low certainty evidence).
CONCLUSIONS
Low to moderate certainty evidence suggests that FV does not have significant additional caries-preventive benefit for children (under 8 years old) when provided as an adjunct to daily tooth brushing with RFT (≥ 1,000 ppm). There is insufficient evidence regarding the additional benefit of other PFA interventions.
CLINICAL RELEVANCE
The decision to apply FV to children needs to be made in light of their actual usage of RFT.
