Meta-Analysis Review
OBJECTIVES
To compare the clinical performance (retention, secondary caries, marginal adaptation, marginal discoloration, and postoperative hypersensitivity) of self-adhesive flowable composite resins (SAFCs) and flowable composite resins (FCs) in permanent teeth with occlusal cavities.
DATA
Randomized controlled trials (RCTs) of SAFCs versus FCs with a follow-up length of at least one year. No restrictions were placed on language or publication date.
SOURCES
Five databases, including PubMed, Embase, Web of Science, Scopus, and the Cochrane Central Register of Controlled Trials, were searched manually by browsing ten related journals. On 14 June 2023, all electronic and manual searches were updated.
STUDY SELECTION
Five RCTs with 138 participants were included. Cochrane's risk of bias tool (2.0) was implemented in selected studies, and the GRADE tool was utilised to evaluate the evidence quality. To summarize the effects of the treatments and pool the data, a random-effects model was used.
CONCLUSIONS
According to the modified United States Public Health Service Evaluation (USPHS) criteria, there was no discernible difference between the groups during the two-year follow-up period (maximum follow-up time). Nevertheless, FCs applied with the etch-and-rinse mode demonstrated superior marginal adaptation and marginal discoloration at the two-year follow-up (relative risk = 3.21 [1.50 to 6.83], 3.40 [1.10, 10.48]). The evidence for marginal discoloration at any recall time and marginal adaptation at the one-year follow-up was graded as moderate quality due to inconsistency. Moreover, low-quality evidence for marginal adaptation at two-year follow-up was due to imprecision and inconsistency.
CLINICAL SIGNIFICANCE
SAFCs exhibited clinical performance comparable to that of FCs in occlusal cavities. Further high-quality clinical trials are needed to provide solid evidence to support the clinical application of SAFCs.

Meta-Analysis Review
Parkinson's disease (PD) biomarkers are needed by both clinicians and researchers (for diagnosis, identifying study populations, and monitoring therapeutic response). Imaging, genetic, and biochemical biomarkers have been widely studied. In recent years, extracellular vesicles (EVs) have become a promising material for biomarker development. Proteins and molecular material from any organ, including the central nervous system, can be packed into EVs and transported to the periphery into easily obtainable biological specimens like blood, urine, and saliva. We performed a systematic review and meta-analysis of articles (published before November 15, 2022) reporting biomarker assessment in EVs in PD patients and healthy controls (HCs). Biomarkers were analyzed using random effects meta-analysis and the calculated standardized mean difference (Std.MD). Several proteins and ribonucleic acids have been identified in EVs in PD patients, but only α-synuclein (aSyn) and leucine-rich repeat kinase 2 (LRRK2) were reported in sufficient studies (n = 24 and 6, respectively) to perform a meta-analysis. EV aSyn was significantly increased in neuronal L1 cell adhesion molecule (L1CAM)-positive blood EVs in PD patients compared to HCs (Std.MD = 1.84, 95% confidence interval = 0.76-2.93, P = 0.0009). Further analysis of the biological sample and EV isolation method indicated that L1CAM-IP (immunoprecipitation) directly from plasma was the best isolation method for assessing aSyn in PD patients. Upcoming neuroprotective clinical trials immediately need peripheral biomarkers for identifying individuals at risk of developing PD. Overall, the improved sensitivity of assays means they can identify biomarkers in blood that reflect changes in the brain. CNS-derived EVs in blood will likely play a major role in biomarker development in the coming years. © 2023 The Authors.

Pain Physician Sep 2023Intraarticular steroid injections are a commonly used and proven treatment for frozen shoulder; however, there is no scientific basis for a certified dose.
BACKGROUND
Intraarticular steroid injections are a commonly used and proven treatment for frozen shoulder; however, there is no scientific basis for a certified dose.
OBJECTIVES
This study aimed to identify the difference between high- and low-dose steroid injections treatments and suggest an appropriate dose.
STUDY DESIGN
Systematic review and meta-analysis.
METHODS
The MEDLINE, EMBASE, and Cochrane electronic databases were searched through February 15, 2023 for eligible randomized controlled trials. The effects of high- and low-dose steroid injections were calculated as standardized mean differences (SMD) in pain, shoulder range of motion (ROM), and functional improvement. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to evaluate evidence quality.
RESULTS
Four studies with 274 patients were included in the final analysis. The meta-analysis showed that improvement in pain (SMD, 0.10; 95% CI, -0.12 to 0.32), ROM (SMD, 0.07; 95% CI, -0.05 to 0.19), and functional improvement (SMD, 0.08; 95% CI, -0.10 to 0.26) did not differ significantly between the high- and low-dose steroid injections. Subgroup follow-up analyses also showed no clinically significant differences in SMD for pain, ROM, and functional scale measurement in any subgroups (after 3 weeks, 6 weeks, and one year). One article described that, although there was no significant difference in adverse events frequency between the high- and low-dose groups, flushing tended to occur more frequently in the high-dose group.
LIMITATIONS
Limitations are the small number of studies included in the meta-analysis, no disease stage considered, and a short follow-up period.
CONCLUSIONS
This meta-analysis suggests there are no significant differences between the high- and low-dose steroid groups in pain, ROM, or functional improvement. Therefore, considering the side effects of high-dose steroids, starting with low-dose steroids is recommended. However, further studies are needed to establish exact protocols according to disease severity.

Review
BACKGROUND
Masticatory dysfunction impacts food selection, nutritional intake and social activities; all of which play a vital role to ensure good general health and quality of life. Despite the rapidly ageing population, there is limited evidence regarding the risk factors that lead to masticatory dysfunction in older adults or protective factors which may help maintain masticatory ability. Furthermore, there is currently no consensus for a specific test which measures masticatory ability.
OBJECTIVES
The objectives of this scoping review are to identify the risk and protective factors associated with masticatory dysfunction and determine the most commonly used objective measure of masticatory performance.
DESIGN
A scoping review was performed using the PRISMA recommendations. MEDLINE (Ovid), Embase, Scopus and Web of Science databases were searched. Seventy-eight articles were included in this review. There were six randomised controlled trials, six interventional studies, one systematic review, one quasi-experimental study, five prospective cohort studies, 58 cross-sectional studies and one case-control study. Data were analysed for frequency of studies reporting on risk factors, protective factors and/or objective measures of masticatory performance.
RESULTS
This scoping review identified tooth loss as the most common risk factor for masticatory dysfunction. Other notable risk factors included musculoskeletal conditions such as frailty and sarcopenia, cognitive decline and malnutrition. Additionally, the review identified that the presence or addition of teeth was the main protective factor. Other protective factors included denture maintenance via liners and adhesives, textured foods, and oral exercises. Chewing gum was the most common objective measure of masticatory function, followed by the occlusal force and sieve methods.
CONCLUSIONS
This scoping review found that there was limited evidence for a causal link between each of the risk factors and masticatory dysfunction or the protective factors and the maintenance of masticatory ability in older adults. Establishing a standard method for measuring masticatory performance such as the commonly used chewing gum method and encouraging clinicians to routinely measure masticatory function will enable comparisons across multiple risk and protective factors, improving the evidence base and contributing to better patient care.

Meta-Analysis Review
OBJECTIVES
The aim of this systematic review and meta-analysis is to assess the comparative clinical success and survival of intracoronal indirect restorations using gold, lithium disilicate, leucite, and indirect composite materials.
MATERIAL AND METHODS
This systematic review and meta-analysis were conducted following the Cochrane Handbook for Systematic Reviews of Interventions and PRISMA guidelines. The protocol for this study was registered in PROSPERO (registration number: CRD42021233185). A comprehensive literature search was conducted across various databases and sources, including PubMed/Medline, Embase, Cochrane Library, Web of Science, ClinicalTrials.gov, and gray literature. A total of 7826 articles were screened on title and abstract. Articles were not excluded based on the vitality of teeth, the language of the study, or the observation period. The risk difference was utilized for the analyses, and a random-effects model was applied. All analyses were conducted with a 95% confidence interval (95% CI). The calculated risk differences were derived from the combined data on restoration survival and failures obtained from each individual article. The presence of heterogeneity was assessed using the I statistic, and if present, the heterogeneity of the data in the articles was evaluated using the non-parametric chi-squared statistic (p < 0.05).
RESULTS
A total of 12 eligible studies were selected, which included 946 restorations evaluated over a minimum observation period of 1 year and a maximum observation period of 7 years. Results of the meta-analysis indicated that intracoronal indirect resin composite restorations have an 18% higher rate of failure when compared to intracoronal gold restorations over 5-7 years of clinical service (risk difference = - 0.18 [95% CI: - 0.27, - 0.09]; p = .0002; I = 0%). The meta-analysis examining the disparity in survival rates between intracoronal gold and leucite restorations could not be carried out due to methodological differences in the studies.
CONCLUSIONS
According to the currently available evidence, medium-quality data indicates that lithium disilicate and indirect composite materials demonstrate comparable survival rates in short-term follow-up. Furthermore, intracoronal gold restorations showed significantly higher survival rates, making them a preferred option over intracoronal indirect resin-composite restorations. Besides that, the analysis revealed no statistically significant difference in survival rates between leucite and indirect composite restorations. The short observation period, limited number of eligible articles, and low sample size of the included studies were significant limitations.
CLINICAL SIGNIFICANCE
Bearing in mind the limitations of the reviewed literature, this systematic review and meta-analysis help clinicians make evidence-based decisions on how to restore biomechanically compromised posterior teeth.

Meta-Analysis Review
The purpose of this study is to evaluate the effects of high-intensity laser therapy (HILT) in patients with frozen shoulder. PRISMA guidelines were adhered to, and a systematic search was conducted in the PubMed, Web of Science, Scopus, CINAHL, Science Direct, and PEDro databases (last update: September 4, 2023; search period: December 2022-September 2023). The inclusion criteria encompassed RCTs comparing HILT with other physical therapy interventions in frozen patients with frozen shoulders, with or without sham HILT, assessing pain intensity, shoulder ROM, and disability outcomes. The quality of the RCTs was assessed with the Cochrane Risk of Bias tool, and evidence was assessed using the GRADE approach. Five trials met the eligibility criteria and were included in the review and meta-analysis, which pooled results from the visual analog scale (VAS), goniometry, and the shoulder pain and disability index (SPADI). Mean differences (MDs) for pain intensity and disability show a pooled effect in favor of HILT both for VAS (MD = - 2.23 cm, 95% CI: - 3.25, - 1.22) and SPADI (MD = - 10.1% (95% CI = - 16.5, - 3.7), changes that are statistical (p < 0.01) and clinical. The MD for flexion (MD = 9.0°; 95% CI: - 2.36°, 20.3°; p = 0.12), abduction (MD = 3.4°; 95% CI: - 6.9°, 13.7°; p = 0.51), and external rotation (MD = - 0.95°; 95% CI: - 5.36°, 3.5°; p = 0.67) does not show statistical and clinical differences between groups after treatment. PI and disability changes were graded as important due to their clinical and statistical results. HILT into a physical therapy plan reduce pain and disability, but it does not outperform conventional physical therapy in improving shoulder ROM. It is suggested that future RCTs compare the effects of HILT and LLLT to assess their possible differences in their analgesic effects.

Meta-Analysis Review
OBJECTIVE
To investigate the therapeutic effects of platelet-rich plasma (PRP) injection on range of motion, pain, and disability in patients with adhesive capsulitis (AC).
DATA SOURCES
The authors performed the literature search in the PubMed, Embase, and Cochrane Library databases in February 2023.
STUDY SELECTION
Prospective studies comparing the outcomes of PRP with other intervention in patients with AC.
DATA EXTRACTION
The quality of included randomized trials was assessed using the revised Cochrane Risk of Bias (RoB 2.0) tool. The Risk of Bias in Non-Randomized Studies of Interventions tool was applied to assess the quality of nonrandomized trials. The mean difference (MD) or standardized mean difference (SMD) was determined as the effect size for continuous outcomes, and outcome accuracy was determined using 95% confidence intervals (CIs).
DATA SYNTHESIS
Fourteen studies involving 1139 patients were included. Our meta-analysis revealed that PRP injection can significantly improve passive abduction (MD=3.91; 95% CI, 0.84-6.98), passive flexion (MD=3.90; 95% CI, 0.15-7.84), and disability (SMD=-0.50; 95% CI, -1.29 to -0.74) within 1 month after intervention. Moreover, PRP injection can significantly improve passive abduction (MD=17.19; 95% CI, 12.38-22.01), passive flexion (MD=17.74; 95% CI, 9.89-25.59), passive external rotation (MD=12.95; 95% CI, 10.04-15.87), pain (MD=-8.40; 95% CI, -16.73 to -0.06), and disability (SMD=-1.02; 95% CI, -1.29 to -0.74) 3 months after intervention. PRP injection can also significantly improve pain (MD=-18.98; 95% CI, -24.71 to -13.26), and disability (SMD=-2.01; 95% CI, -3.02 to -1.00) 6 months after intervention. In addition, no adverse effects of PRP injection were reported.
CONCLUSIONS
PRP injection may serve as an effective and safe treatment for patients with AC.

Review
OBJECTIVE
to evaluate the existing evidence on surface treatment techniques employed in resin composite repair and their effect on the repair short- and long-term bond strength.
DATA AND SOURCE
This scoping review was performed under the PRISMA-ScR guidelines for scoping reviews and registered on the Open Science Framework platform.
STUDY SELECTION
A systematic search was conducted in PubMed, Embase, and Scopus and grey literature up to September 2022 without language or date restriction. In vitro studies comparing mechanical surface and/or chemical treatments on repair bond strength of resin composite were included. Studies evaluating experimental adhesive systems or resin composites were excluded. Selection of studies and data extraction were performed. Data from selected studies was qualitatively analyzed.
RESULTS
A total of 76 studies were included in the qualitative analysis. Among the mechanical treatments, alumina blasting was the most frequently used, followed by silica coating and diamond bur. As for chemical treatments, dentin bonding systems were the most frequently evaluated, followed by universal adhesive systems and silane/ceramic primer. The combination of mechanical and chemical pre-treatments increased the repair bond strength of resin composite in both short- and long-term simulated aging scenarios. The evidence obtained from the included studies was classified as moderate quality, mainly due to the medium risk of bias observed across most of the studies.
CONCLUSION
The techniques used to treat the surface of resin composites for repair are diverse. Incorporating a combination of mechanical and chemical pre-treatments resulted in superior repair bond strength of resin composite materials under both short- and long-term simulated aging conditions.
CLINICAL SIGNIFICANCE
The analysis of evidence revealed significant variability among protocols for repairing resin composites. Utilizing both mechanical and chemical pre-treatment methods is important for enhancing the bond strength of resin composites during both short- and long-term simulated aging situations.

BACKGROUND
Over 1.1 billion people smoke worldwide. The alkaloid nicotine is a prominent and addictive component of tobacco. In addition to tumors and cardiovascular disorders, tobacco consumption is associated with a variety of chronic-inflammatory diseases. Although neutrophilic granulocytes (neutrophils) play a role in the pathogenesis of many of these diseases, the impact of nicotine on neutrophils has not been systematically reviewed so far.
OBJECTIVES
The aim of this systematic review was to evaluate the direct influence of nicotine on human neutrophil functions, specifically on cell death/damage, apoptosis, chemotaxis, general motility, adhesion molecule expression, eicosanoid synthesis, cytokine/chemokine expression, formation of neutrophil extracellular traps (NETs), phagocytosis, generation of reactive oxygen species (ROS), net antimicrobial activity, and enzyme release.
MATERIAL AND METHODS
This review was conducted according to the PRISMA guidelines. A literature search was performed in the databases NCBI Pubmed and Web of Science™ in February 2023. Inclusion criteria comprised English written research articles, showing studies on the direct impact of nicotine on specified human neutrophil functions.
RESULTS
Of the 532 originally identified articles, data from 34 articles were finally compiled after several evaluation steps. The considered studies highly varied in methodological aspects. While at high concentrations (>3 mmol/l) nicotine started to be cytotoxic to neutrophils, concentrations typically achieved in blood of smokers (in the nmol/l range) applied for long exposure times (24-72h) supported the survival of neutrophils. Smoking-relevant nicotine concentrations also increased the chemotaxis of neutrophils towards several chemoattractants, elevated their production of elastase, lipocalin-2, CXCL8, leukotriene B4 and prostaglandin E2, and reduced their integrin expression. Moreover, while nicotine impaired the neutrophil phagocytotic and anti-microbial activity, a range of studies demonstrated increased NET formation. However, conflicting effects were found on ROS generation, selectin expression and release of β-glucuronidase and myeloperoxidase.
CONCLUSION
Nicotine seems to support the presence in the tissue and the inflammatory and selected tissue-damaging activity of neutrophils and reduces their antimicrobial functions, suggesting a direct contribution of nicotine to the pathogenesis of chronic-inflammatory diseases via influencing the neutrophil biology.

Meta-Analysis Review
Is there any advantage between using continuous passive motion and conventional physical therapy in patients with primary adhesive capsulitis?: A systematic review and meta-analysis.
BACKGROUND
We are unsure if continuous passive motion (CPM) has any role in the nonoperative management of the Primary Stiff Shoulder (frozen shoulder). We hypothesized that there is no difference in pain improvement, range of motion, and function with or without CPM in patients with a primary stiff shoulder.
METHOD
We searched the databases for clinical trials comparing CPM versus no-CPM physiotherapy. In the final step, we reviewed five randomized clinical trials. We collected the data of Constant Shoulder Score (CSS), the visual analog scale of pain, shoulder pain and disability index (SPADI), and range of motion (flexion, abduction, external and internal rotation). We used a random-effects model to analyze the data.
RESULTS
Five studies with a total of 224 patients were included. There were 113 patients in the CPM arm and 111 in the control arm. Both the CPM and control groups showed significant improvements in all measured parameters compared to the first visit after 8-24 weeks. Meta-analysis of pooled data showed significant differences in pain improvement, forward flexion, and CSS favoring the CPM. Still, there was no significant difference in abduction, external and internal rotation, and SPADI.
DISCUSSION
The CPM seems to be slightly effective in improving pain and motion in the short term, but its long-term efficacy is still under question. The extra cost and time must be considered when offering the CPM.
