Meta-Analysis Review
BACKGROUND
To evaluate the effectiveness of the use of antimicrobial photodynamic therapy (aPDT) in root canals disinfection in cases of endodontic retreatments.
METHODS
This Systematic Review was registered in PROSPERO (CRD42021260013) and followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Searches were performed in the electronic databases PubMeb, Scopus, Web of Science, Embase, Web of Science, Clinical Trials and Cochrane Library. Methodological quality and risk of bias were assessed by the Cochrane Risk of Bias tool for randomized clinical trials (RCT) and by the Newcastle-Ottawa (NOS) qualifier for non-RCT (prospective) studies. Meta-analysis was performed using R software, version 3.6.3 with the "META" package assistant by the RStudio platform. The odds ratio (OR) measure of effect was calculated and the random effect model was applied with a 95% confidence interval, and heterogeneity tested by the I2 index. The certainty of evidence was rated using GRADE.
RESULTS
Regarding the 1513 studies screened, 10 met the eligibility criteria and were included, and 8 used in the quantitative synthesis. Meta-analysis showed that all of studies data presented a significant difference before and after of antimicrobial photodynamic therapy in the microbial load reduction in secondary endondontic infections (OR 0.15 [0.07; 0.32], p < 0.0001). Overall, the studies had a low risk of bias and, the analysis of evidence by GRADE assessment was rated as moderate.
CONCLUSION
It is suggested that aPDT is a beneficial and promising tool, showing efficacy in reducing the microbial load in cases of endodontic retreatment.

INTRODUCTION
The antimicrobial trimethoprim is structurally related to potassium-sparing diuretics and may consequently lead to derangements in electrolyte and acid-base balance. Since no report so far analyzed the literature documenting individual cases with electrolyte and acid-base derangements induced by trimethoprim, a systematic review was carried out.
EVIDENCE ACQUISITION
We retained 53 reports documenting 68 cases (42 males and 26 females 23 to 96 years of age) of electrolyte or acid-base derangements occurring on trimethoprim for about 5 days.
EVIDENCE SYNTHESIS
One hundred five electrolyte imbalances were detected in the 68 patients: hyperkalemia (>5.0 mmol/L) in 62 (91%), hyponatremia (<135 mmol/L) in 29 (43%) and metabolic acidosis (pH<7.38 and bicarbonate <19 mmol/L) in 14 (21%) cases. Following possible predisposing factors for electrolyte and acid-base abnormalities were found in 54 (79%) patients: high-dose trimethoprim, comedication with drugs that have been associated with electrolyte and acid-base derangements, preexisting kidney disease, age ≥80 years and diabetes mellitus.
CONCLUSIONS
High-dose trimethoprim, comedicated with drugs that have been associated with electrolyte and acid-base derangements, poor kidney function, age ≥80 years and diabetes mellitus predispose to trimethoprim-associated electrolyte and acid-base abnormalities. Clinicians must recognize patients at risk, possibly avoid drug combinations that may worsen the problem and monitor the laboratory values.

Review
Leishmaniasis is an infectious disease responsible for a huge rate of morbidity and mortality in humans. Chemotherapy consists of the use of pentavalent antimonial, amphotericin B, pentamidine, miltefosine, and paromomycin. However, these drugs are associated with some drawbacks such as high toxicity, administration by parenteral route, and most seriously the resistance of some strains of the parasite to them. Several strategies have been used to increase the therapeutic index and reduce the toxic effects of these drugs. Among them, the use of nanosystems that have great potential as a site-specific drug delivery system stands out. This review aims to compile results from studies that were carried out using first- and second-line antileishmanial drug-carrying nanosystems. The articles referred to here were published between 2011 and 2021. This study shows the promise of effective applicability of drug-carrying nanosystems in the field of antileishmanial therapeutics, with the perspective of providing better patient adherence to treatment, increased therapeutic efficacy, reduced toxicity of conventional drugs, as well as the potential to efficiently improve the treatment of leishmaniasis.

Meta-Analysis Review
OBJECTIVES
The purpose of the present systematic review and meta-analysis was to assess the available evidence regarding the efficacy of curcumin mouthwashes on plaque and gingivitis.
METHODS
A comprehensive online search of multiple databases (PubMed, Scopus, Web of Science, and Google Scholar) was performed to identify all relevant studies published up to August 2020, using the following keywords: curcumin, turmeric, gingivitis, periodontal health, and plaque control. All clinical trials that compared the efficacy of curcumin mouthwash with chlorhexidine in controlling dental plaque and gingivitis were included. Data were analysed using Review Manager (RevMan) 5.3 software. The risk of bias was evaluated by two independent reviewers using the Cochrane assessment tool.
RESULTS
Six randomized clinical trials (comprising 320 subjects) fulfilled the eligibility criteria. Five studies showed a high risk of bias and only one study showed a low risk of bias. The pooled data of the six included studies revealed comparable efficacy of curcumin and chlorhexidine in reducing dental plaque (I = 91%; standardized mean difference [SMD]: 0.27, 95% CI: -0.53, 1.07, p = 0. 51) and gingival inflammation (I = 40%; SMD: -0.13, 95% CI: -0.35, 0.09, p = 0.24), with no statistically significant differences between the two groups.
CONCLUSION
The results suggest that curcumin mouthwashes have promising anti-plaque and anti-gingivitis properties. Further clinical trials with adequate sample sizes and standardized methodologies are required to discern the efficacy of curcumin mouthwash in reducing plaque and gingivitis.

Review
Natural products from plants have gained prominence in the search for therapeutic alternatives. Monoterpenes, such as carvone, are suggested as candidates for the treatment of several diseases. Therefore, the objective of this study is to review the pharmacological activities of carvone in experimental models in vitro and in vivo. For this, the searches were carried out in May 2020 (upgraded in July 2021) in the databases of PubMed, Web of Science and Scopus and gathered studies on the pharmacological activities of carvone. Two independent reviewers performed the selection of articles using the Rayyan application, extracted the relevant data and assessed the methodological quality of the selected studies using Syrcle's risk of bias tool. Ninety-one articles were selected that described 10 pharmacological activities of carvone, such as antimicrobial, antispasmodic, anti-inflammatory, antioxidant, antinociceptive, anticonvulsant, among others. The evaluation of the methodological quality presented an uncertain risk of bias for most studies. In light of that, carvone stands out as a viable and promising alternative in the treatment of several pathological conditions. However, carrying out studies to evaluate possible mechanisms of action and the safety of this monoterpene is recommended.

Review
The objective of this systematic review was to retrieve and examine published studies related to in vitro and in vivo evaluation of disulfiram for the treatment of bacterial infections. Five scientific databases (PubMed, Embase, Scopus, Web of Science, and Latin American and Caribbean Health Sciences Literature) were searched to retrieve the maximum literature regarding the study's aim. The search strategy retrieved a total of 870 studies, of which 31 were included and 19 approached disulfiram as the primary aim and 12 included it as a secondary finding from other investigational objectives. The evidence pointed out five main aspects of pre-clinical testing regarding disulfiram antibacterial activity, namely spectrum of antimicrobial action, drug combinations, intracellular studies, animal studies and bacterial targets. Findings to emerge from this study are the observed potential of disulfiram as a non-antibiotic drug being proposed as a potential drug to contribute to the treatment of bacterial diseases usually with few treatment alternatives in the context of drug resistance. We evaluated the potency and selectivity of disulfiram, which indeed until now shows potential to be explored for use as an adjunctive chemical to antimicrobial ones. Even with the level of evidence being reserved, the potential of combining disulfiram with other drugs, already used or new to be used for the treatment of mycobacterial diseases, as well as its likely immunomodulatory effect, deserve to be further investigated. Furthermore, the copper-dependent mode of action in Gram-positive bacteria is an alternative to be explored in drug design or repurposing of chemicals.

Meta-Analysis
BACKGROUND
Otitis externa is a condition causing inflammation of the outer ear canal, which presents with itching, discharge and pain. Most cases of acute otitis externa are caused by bacterial infection and are thus treated with antibiotics. This systematic review and meta-analysis of randomised controlled trials aims to assess the effectiveness of topical non-antibiotic treatments compared to topical antibiotic treatment for the treatment of acute otitis externa.
METHODS
Systematic review and meta-analysis databases searched: Cochrane Library including ClinicalTrials.gov; MEDLINE; World Health Organisation International Clinical Trials Registry Platform and Web of Science to identify randomised clinical trials evaluating topical antibiotics and topical non-antibiotic agents in adults and children with acute otitis externa. Non-antibiotic therapeutics for comparison with topical antibiotics included antiseptics, steroids, non-pharmaceuticals and astringents.
RESULTS
Seventeen trials were eligible for inclusion, with 10 combined in meta-analysis. Data could be pooled comparing antiseptic and steroid monotherapies with topical antibiotic agents. There were no significant differences in cure rates in any pairwise comparisons. Individually, the majority of studies favoured topical antiseptics or steroids over antibiotics, however these differences were not significant when pooled in meta-analysis.
CONCLUSION
Antiseptic, steroid and antibiotic monotherapies are all effective for the management of acute otitis externa. There is insufficient evidence to suggest that topical antiseptic or steroid agents are superior or inferior to topical antibiotics.

Review
AIM
The aim of this systematic review was to evaluate the efficacy of patient-performed or administered adjunctive measures to non-surgical peri-implantitis therapy in terms of probing depth (PD) and/or bleeding on probing (BoP) reductions.
MATERIALS AND METHODS
Randomized and controlled clinical trials with at least 6 months of follow-up were searched in three databases. Secondary outcomes included implant loss, disease resolution, recurrence of peri-implantitis, need of re-treatment, changes in marginal bone levels, patient-reported outcomes and adverse effects.
RESULTS
Of 567 titles, 10 publications, reporting 9 investigations, were included. Three types of adjunctive measures were found (local/systemic antimicrobials and probiotics). Four studies evaluated the effects of local antimicrobials (i.e., minocycline microspheres, chlorhexidine chips or a metronidazole + amoxicillin gel), three studies evaluated systemic antimicrobials (either amoxicillin + metronidazole or metronidazole alone) and two studies evaluated probiotics (Lactobacillus reuteri strains). The addition of local antimicrobials led to modest improvements in PD reduction. Systemic antimicrobials showed significantly greater reductions in PD and BoP, especially at initially deep sites (PD > 6 mm). Due to the large heterogeneity among included studies, no meta-analyses were performed.
CONCLUSIONS
Different adjunctive measures in the non-surgical treatment of peri-implantitis have different impact in terms of PD and BoP reductions. Improved PD reductions result after the use of systemic antimicrobials, and to a lesser extent, after the use of local antimicrobials.

Review
Due to the increasing bacterial resistance to conventional antibiotics, developing safe and effective approaches to combat infections caused by bacteria and biofilms has become an urgent clinical problem. Recently, carbon dots (CDs) have received great attention as a promising alternative to conventional antimicrobial agents due to their excellent antimicrobial efficacy and biocompatibility. Although CDs have been widely used in the field of antibacterial applications, their antibacterial and antibiofilm mechanisms have not been systematically discussed. This review provides a systematic overview on the complicated mechanisms of antibacterial and antibiofilm CDs based on recent development.

Review
CONTEXT
Sodium hypochlorite, a gold standard for irrigation in endodontics, has disadvantages like toxicity and root dentin weakening. Alternatives derived from natural products are being explored.
AIMS
This systematic review was done to understand the clinical benefits of natural irrigants when compared with a standard irrigant, sodium hypochlorite.
SETTINGS AND DESIGN REGISTRATION
This systematic review was registered with PROSPERO (2018 CRD42018112837) METHODS AND MATERIAL: This review was done in conformation to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA 2020) statement. In vivo studies using at least one natural irrigant and sodium hypochlorite (NaOCl) were included. Studies using them as medicaments were excluded. PubMed, Cochrane and SCOPUS were searched. RevMan tool for Risk of Bias 2 (RoB 2) and risk-of-bias tool to assess non-randomized studies of interventions (ROBINS-I) were used. GRADEpro was used to assess certainty of evidence.
RESULTS
Ten articles (6 RCTs and 4 clinical studies) on approximately 442 patients were included. Seven natural irrigants were evaluated clinically. Due to the heterogeneity, meta-analysis could not be conducted. Antimicrobial efficacy was found to be similar for castor oil, neem, garlic-lemon, noni, papaine and NaOCl. Neem, papaine-chloramine, neem-NaOCl and neem-CHX were superior, while propolis, miswak and garlic were inferior to NaOCl. Post-operative pain was less for neem. There was no significant difference between papaine-chloramine, garlic extract and sodium hypochlorite in clinical/radiographic success.
CONCLUSIONS
The studied natural irrigants are not more efficacious than NaOCl. At the moment, they cannot replace NaOCl routinely and may only substitute in select cases.
