Review
BACKGROUND
The purpose of this systematic review was to assess the clinical efficacy (sensitivity reduction) and safety (gum damage) of silver diamine fluoride (SDF) as a tooth desensitizer for adults.
METHODS
The search strategy was developed and adapted from 12 databases. Two independent reviewers selected the studies in consensus with a third reviewer. Randomized clinical trials with adult volunteers affected by dentin hypersensitivity (DH), and receiving treatment with SDF were included. Studies with volunteers testing tooth whitening products, using some type of desensitizer, or taking analgesic or anti-inflammatory medication were excluded. The risk of bias was assessed according to the RoB 2 tool, and confidence in cumulative evidence, according to GRADE.
RESULTS
Only 3 articles were included. The average pain assessed using the visual analog scale was lower in the SDF groups than in the short-term control groups (24h to 7 days) (=0.0134 and =0.0015) of the two studies. The third study evaluated a combination of SDF and a CO laser, compared to using only SDF, and found no statistical difference between the two (=0.74). Inflammation and gingival staining were also evaluated in two of the three studies. No adverse effects were reported. All the included studies had a high risk of bias, and the certainty of the evidence was very low.
CONCLUSION
SDF can be used as a safe and effective tooth desensitizer in adults, with good results, as was achieved in a short-term follow-up. However, more studies with longer evaluation periods are required.

Meta-Analysis Review
INTRODUCTION
Neurological deterioration, soon after anti-copper treatment initiation, is problematic in the management of Wilson's disease (WD) and yet reports in the literature are limited. The aim of our study was to systematically assess the data according to early neurological deteriorations in WD, its outcome and risk factors.
METHODS
Using PRISMA guidelines, a systematic review of available data on early neurological deteriorations was performed by searching the PubMed database and reference lists. Random effects meta-analytic models summarized cases of neurological deterioration by disease phenotype.
RESULTS
Across the 32 included articles, 217 cases of early neurological deterioration occurred in 1512 WD patients (frequency 14.3%), most commonly in patients with neurological WD (21.8%; 167/763), rarely in hepatic disease (1.3%; 5/377), and with no cases among asymptomatic individuals. Most neurological deterioration occurred in patients treated with d-penicillamine (70.5%; 153/217), trientine (14.2%; 31/217) or zinc salts (6.9%; 15/217); the data did not allow to determine if that reflects how often treatments were chosen as first line therapy or if the risk of deterioration differed with therapy. Symptoms completely resolved in 24.2% of patients (31/128), resolved partially in 27.3% (35/128), did not improve in 39.8% (51/128), with 11 patients lost to follow-up.
CONCLUSIONS
Given its occurrence in up to 21.8% of patients with neurological WD in this meta-analysis of small studies, there is a need for further investigations to distinguish the natural time course of WD from treatment-related early deterioration and to develop a standard definition for treatment-induced effects.

This systematic review, conducted according to the PRISMA guidelines, focuses on genotoxicity of oxidative hair dye precursors. The search for original papers published from 2000 to 2021 was performed in Medline, Web of Science, Cochrane registry, Scientific Committee on Consumer Safety of the European Commission and German MAK Commission opinions. Nine publications on genotoxicity of -phenylenediamine (PPD) and toluene-2,5-diamine (-toluylenediamine; PTD) were included, reporting results of 17 assays covering main genotoxicity endpoints. PPD and PTD were positive in bacterial mutation assay, and PPD tested positive also for somatic cell mutations in the Rodent assay . Clastogenicity of PPD and PTD was revealed by chromosomal aberration assay. The alkaline comet assay showed DNA damage after PPD exposure, which was not confirmed where PTD exhibited positive results. PPD induced micronucleus formation , and increased micronucleus frequencies in mice erythrocytes following high dose oral exposure . Based on the results of a limited number of data from the classical genotoxicity assay battery, this systematic review indicates genotoxic potential of hair dye precursors PPD and PTD, which may present an important health concern for consumers and in particular for professional hairdressers.

BACKGROUND AND AIMS
Some studies have reported that the topical forms with aminophylline as the active ingredient appear to be relatively effective on local fat burning while having no/minimal side effects. This systematic review accumulates all of the data on the local fat-burning potency of aminophylline topical formulation.
METHODS
Documents were retrieved from PubMed, Web of Science, and Scopus databases until Aug 2022. Data were extracted from clinical trials reporting the reduction in thigh or waist circumference as a result of using topical forms containing aminophylline. Screening of included studies was performed independently by two authors and the quality assessment of included studies was performed based on the Cochrane Collaboration's approach.
RESULTS
Of the 802 initial studies, 5 studies were included in the systematic review. Several concentrations of aminophylline were used in different studies. Most studies administred the topical formulation on participants' one thigh, and the other thigh was considered to be the control for comparing the fat reduction amount. Except for one study, all other studies reported that all participants lost more fat on the treated area than the control groups. The amount of fat reduction differed in studies regarding their different aminophylline concentrations and administration routines. In the case of side effects, except for some studies reporting skin rashes, other studies reported no significant side effects at all.
CONCLUSIONS
Aminophylline topical formulation offers a safe, effective, and much less invasive alternative to cosmetic surgery for localized fat reduction. It seems that the 0.5% concentration, administered five times a week for five weeks is the most potent concentration. However, more high-quality clinical trials are needed to verify this conclusion.

Review
The extended use of ethambutol beyond 2 months for treating tuberculosis has increased risk of optic neuropathy. We performed a systematic review of studies evaluating optic neuropathy in extended ethambutol use since 2010 and compared the outcome with a similar systematic review (1965-2010) by Ezer et al. Literature search was conducted in PubMed, Medline, EMBASE, and Cochrane databases. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Main outcome measures were visual acuity, color vision, visual field defects, optical coherence tomography (OCT), and visual evoked potential (VEP). The JBI Critical Appraisal Checklists were used for quality assessment. Twelve studies were selected (out of 639 studies) for analysis of ethambutol optic neuropathy. Visual acuity improvement after stopping ethambutol was statistically significant. Similar improvement was not noted for other outcome measures. On comparing the results of this review with those by Ezer et al., significant improvement was noted in visual acuity, color vision, and visual field defects. Moreover, more patients reported increased optic nerve toxicity, color vision defects, and visual field defects in the present review. Hence, we conclude that the extended use of ethambutol beyond 2 months results in significant optic nerve toxicity. Further randomized controlled trials with different populations are needed to understand the magnitude of this issue.

OBJECTIVES
The objective of this review is to assess the available literature systematically related to the effect of silver diamine fluoride (SDF) for the management of occlusal and root carious lesions in permanent teeth regardless of age. MATERIALS AND METHODS: This systematic review was conducted according to the Cochrane Handbook for Systematic Reviews of Interventions and Preferred Reporting Items for Systematic Review and Meta-Analyses statement. A literature search was performed using PubMed/MEDLINE, Cochrane Central Register of Controlled Trials, Web of Science, DOAJ, and Open Gray with no language restrictions up to December 2022. Three reviewers critically assessed the studies for eligibility. Any disputes between the reviewers were handled by a fourth independent reviewer. The quality assessment and data extraction of the studies were performed.
RESULTS
A total of 2176 studies were screened. The titles and abstracts of the studies were then reviewed (n = 346), and 52 studies met the search criteria. Following the full-text review, 11 studies investigated the effect of SDF against other treatments such as chlorhexidine, sodium fluoride, ammonium bifluoride, tricalcium silicate paste, casein phosphopeptide amorphous calcium phosphate, glass ionomer cement (GIC) combined with fluoride varnish, resin-modified GIC, and atraumatic restorative treatment were assessed.
CONCLUSIONS
Within the limitations of this review, the use of SDF is promising with high preventative fractions in permanent teeth of children and older populations when compared to other topical applications such as dental varnish containing sodium fluoride.

Meta-Analysis
BACKGROUND
Optimal doses of first-line drugs for treatment of drug-susceptible tuberculosis in children and young adolescents remain uncertain. We aimed to determine whether children treated using World Health Organization-recommended or higher doses of first-line drugs achieve successful outcomes and sufficient pharmacokinetic (PK) exposures.
METHODS
Titles, abstracts, and full-text articles were screened. We searched PubMed, EMBASE, CENTRAL, and trial registries from 2010 to 2021. We included studies in children aged <18 years being treated for drug-susceptible tuberculosis with rifampicin (RIF), pyrazinamide, isoniazid, and ethambutol. Outcomes were treatment success rates and drug exposures. The protocol for the systematic review was preregistered in PROSPERO (no. CRD42021274222).
RESULTS
Of 304 studies identified, 46 were eligible for full-text review, and 12 and 18 articles were included for the efficacy and PK analyses, respectively. Of 1830 children included in the efficacy analysis, 82% had favorable outcomes (range, 25%-95%). At World Health Organization-recommended doses, exposures to RIF, pyrazinamide, and ethambutol were lower in children than in adults. Children ≤6 years old have 35% lower areas under the concentration-time curve (AUCs) than older children (mean of 14.4 [95% CI 9.9-18.8] vs 22.0 [13.8-30.1] μg·h/mL) and children with human immunodeficiency virus (HIV) had 35% lower RIF AUCs than HIV-negative children (17.3 [11.4-23.2] vs 26.5 [21.3-31.7] μg·h/mL). Heterogeneity and small sample sizes were major limitations.
CONCLUSIONS
There is large variability in outcomes, with an average of 82% favorable outcomes. Drug exposures are lower in children than in adults. Younger children and/or those with HIV are underexposed to RIF. Standardization of PK pediatric studies and individual patient data analysis with safety assessment are needed to inform optimal dosing.

Review
. has been implicated in infections of treated root canals. Current irrigants and intracanal medicaments cannot eliminate completely from the root canal. Silver diamine fluoride (SDF) prevents caries by promoting remineralization and exerting an antibacterial effect. Studies suggest that SDF may possess antibacterial properties against . The purpose of this review is to systematically and critically analyze the literature, focusing on the use of SDF as an intracanal medicament or irrigant, when compared to other antibacterial agents. . The focused question was "Is the antibacterial effect of SDF against better than other intracanal medicaments and irrigants?" Using the keywords ((silver diamine fluoride) AND ()) AND ((sodium hypochlorite) OR (NaOCl) OR (chlorhexidine) OR (calcium hydroxide) OR (Ca(OH))), an electronic search was conducted on the following databases: PubMed/MEDLINE, ISI Web of Science, Scopus, EMBASE, and Google Scholar. The clinical trial registers ClinicalTrials.gov and CONTROL were also searched using the same keywords. General characteristics and outcomes were extracted, and quality of the studies was assessed using the Preferred Reporting Items for Laboratory studies in Endodontology (PRILE) guidelines. . Six articles (five studies and one study) were included in this systematic review. In the majority of the studies, SDF had equal or better antibacterial efficacy against compared to calcium hydroxide, sodium hypochlorite, and chlorhexidine. However, the majority of the studies did not fulfill several items in the PRILE criteria and had numerous sources of bias. . Within the limitations of the systematic review and the studies reviewed, SDF may be effective against and therefore could be used as an intracanal medicament and/or irrigant to prevent reinfections of the root canals and improve the outcomes of endodontic treatment. However, animal and clinical studies should be carried out to determine the efficacy of SDF in endodontics. . The protocol for this review was registered on PROSPERO. Registration number: CRD42021224741.

Review
Apart from the major drawback of black staining once lesion is arrested, few studies have indicated that dental personnel's perception and attitude towards silver diamine fluoride (SDF) influences its usage. This report aims to provide a systematic review presenting dental personnel's knowledge, attitudes, and perceptions, (KAPs) regarding SDF. A search of multiple electronic literature databases and a manual search were performed. The review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 statement. A comprehensive search yielded 719 publications and 14 cross-sectional studies matching the inclusion criteria. Awareness of SDF among respondents ranged from 29.6% to 87.8%, whereas awareness of its use in dentistry ranged from 14.4% to 94.5%. Regarding attitude towards SDF, the mean score ranged from 3.39 to 14.35. An increase in knowledge of and attitude towards SDF is significantly associated with the usage of SDF and may increase the usage of SDF. This review provides vital information on dental personnel's KAPs regarding SDF. It is anticipated that the adaptation of SDF usage will be more widespread in the future, especially among children. Findings from the review may assist intervention programs to change misperceptions and to enhance awareness regarding SDF among dental personnel.

Meta-Analysis Review
BACKGROUND
Suboptimal exposure to antituberculosis (anti-TB) drugs has been associated with unfavourable treatment outcomes. We aimed to investigate estimates and determinants of first-line anti-TB drug pharmacokinetics in children and adolescents at a global level.
METHODS
We systematically searched MEDLINE, Embase and Web of Science (1990-2021) for pharmacokinetic studies of first-line anti-TB drugs in children and adolescents. Individual patient data were obtained from authors of eligible studies. Summary estimates of total/extrapolated area under the plasma concentration-time curve from 0 to 24 h post-dose (AUC) and peak plasma concentration ( ) were assessed with random-effects models, normalised with current World Health Organization-recommended paediatric doses. Determinants of AUC and were assessed with linear mixed-effects models.
RESULTS
Of 55 eligible studies, individual patient data were available for 39 (71%), including 1628 participants from 12 countries. Geometric means of steady-state AUC were summarised for isoniazid (18.7 (95% CI 15.5-22.6) h·mg·L), rifampicin (34.4 (95% CI 29.4-40.3) h·mg·L), pyrazinamide (375.0 (95% CI 339.9-413.7) h·mg·L) and ethambutol (8.0 (95% CI 6.4-10.0) h·mg·L). Our multivariate models indicated that younger age (especially <2 years) and HIV-positive status were associated with lower AUC for all first-line anti-TB drugs, while severe malnutrition was associated with lower AUC for isoniazid and pyrazinamide. -acetyltransferase 2 rapid acetylators had lower isoniazid AUC and slow acetylators had higher isoniazid AUC than intermediate acetylators. Determinants of were generally similar to those for AUC.
CONCLUSIONS
This study provides the most comprehensive estimates of plasma exposures to first-line anti-TB drugs in children and adolescents. Key determinants of drug exposures were identified. These may be relevant for population-specific dose adjustment or individualised therapeutic drug monitoring.
