Guided bone regeneration techniques are increasingly used to enable the subsequent placement of dental implants. This systematic review aims to analyze the success rate of these techniques in terms of bone gain and complications rate using titanium membranes as a barrier element. Electronic and hand searches were conducted in PubMed/Medline, Scielo, Scopus and Cochrane Library databases for case reports, case series, cohort studies and clinical trials in humans published up to and including 19 September 2020. Thirteen articles were included in the qualitative analysis. Bone gain both horizontally and vertically was comparable to that obtained with other types of membranes more commonly used. The postoperative complication rate was higher that of native collagen membranes and non-resorbable titanium-reinforced membranes, and similar that of crosslinked collagen membranes and titanium meshes. The survival rate of the implants was similar to that of implants placed in native bone. Due to the limited scientific literature published on this issue, more randomized clinical trials comparing occlusive titanium barriers and other types of membranes are necessary to reach more valid conclusions.

The presence of satisfactory bone volume is fundamental for the achievement of osseointegration. This systematic review aims to analyse the use of titanium meshes in guided bone regeneration in terms of bone gain, survival and success rates of implants, and percentages of exposure. An electronic search was conducted Articles were selected from databases in MEDLINE (PubMed), SCOPUS, Scielo, and Cochrane Library databases to identify studies in which bone regeneration was performed through particulate bone and the use of titanium meshes. Twenty-one studies were included in the review. In total, 382 patients, 416 titanium meshes, and 709 implants were evaluated. The average bone gain was 4.3 mm in horizontal width and 4.11 mm in vertical height. The mesh exposure was highly prevalent (28%). The survival rate of 145 simultaneous implants was 99.5%; the survival rate of 507 delayed implants was 99%. The success rate of 105 simultaneous implants was 97%; the success rate of 285 delayed implants was 95.1%. The clinical studies currently available in the literature have shown the predictability of this technique. It has a high risk of soft tissue dehiscence and membrane exposure although the optimal management of membrane exposition permits obtaining a sufficient bone regeneration volume and prevents compromising the final treatment outcome.

The purpose of this study was to evaluate the efficacy and safety of photobiomodulation as an adjuvant treatment for primary headache. A systematic review of randomized clinical trials was performed. For such, electronic searches were performed in the MEDLINE, Embase, Cochrane Library, LILACS, PEDro, PsycInfo, Clinicaltrials.gov., and WHO/ICTRP databases, with no restrictions imposed regarding language or year of publication. We included studies that assessed any photobiomodulation therapy as an adjuvant treatment for primary headache compared to sham treatment, no treatment, or another intervention. The methodological assessment was conducted using the Cochrane Risk of Bias tool. The certainty of the evidence was classified using the GRADE approach. Four randomized clinical trials were included. Most of the included studies had an overall high risk of bias. Compared to sham treatment, photobiomodulation had a clinically important effect on pain in individuals with primary headache. Despite the benefits reported for other outcomes, the estimates were imprecise, and the certainty of the evidence was graded as low. These findings are considered insufficient to support the use of photobiomodulation in the treatment of primary headache. Randomized clinical trials, with higher methodological quality, are needed to enhance the reliability of the estimated effects.

SUMMARY Objectives The aim of this review was to assess the methodologies used in previously published prospective randomized clinical trials on chemomechanical caries removal and to conduct a meta-analysis to quantify the differences in the excavation time between chemomechanical and conventional caries removal methods. Methods An electronic search was performed using Scopus, PubMed, EBSCO host, and Cochrane Library databases. The following categories were excluded during the assessment process: non-English studies published before 2000, animal studies, review articles, laboratory studies, case reports, and nonrandomized or retrospective clinical trials. The methodologies of the selected clinical trials were assessed. Furthermore, the reviewed clinical trials were subjected to meta-analysis for quantifying the differences in excavation time between the chemomechanical and the conventional caries removal techniques. Results Only 19 randomized clinical trials fit the inclusion criteria of this systematic review. None of the 19 reviewed trials completely fulfilled Delphi's ideal criteria for quality assessment of randomized clinical trials. The meta-analysis results revealed that the shortest mean excavation time was recorded for rotary caries excavation (2.99±0.001 minutes), followed by the enzyme-based chemomechanical caries removal method (6.36±0.08 minutes) and the the hand excavation method (atraumatic restorative technique; 6.98±0.17 minutes). The longest caries excavation time was recorded for the sodium hypochlorite-based chemomechanical caries removal method (8.12±0.02 minutes). Conclusions It was found that none of the current reviewed trials fulfilled all the ideal requirements of clinical trials. Furthermore, the current scientific evidence shows that the sodium hypochlorite-based (Carisolv) chemomechanical caries removal method was more time consuming when compared to the enzyme-based (Papacarie) chemomechanical and the conventional caries removal methods. Further prospective randomized controlled clinical trials evaluating the long-term follow-up of papain-treated permanent teeth are needed.

Introduction: Several experimental studies in the literature have tested different biology-based methods for inhibiting or decreasing orthodontic tooth movement (OTM) in humans. This systematic review investigated the effects of these interventions on the rate of tooth movement. Study design: Electronic [MedLine; SCOPUS; Cochrane Library; OpenGrey;Web of Science] and manual searches were conducted up to January 26th, 2016 in order to identify publications of clinical trials that compared the decreasing or inhibiting effects of different biology-based methods over OTM in humans. A primary outcome (rate of OTM deceleration/inhibition) and a number of secondary outcomes were examined (clinical applicability, orthodontic force used, possible side effects). Two reviewers selected the studies complying with the eligibility criteria (PICO format) and assessed risk of bias [Cochrane Collaboration's tool]. Data collection and analysis were performed following the Cochrane recommendations. Results: From the initial electronic search, 3726 articles were retrieved and 5 studies were finally included. Two types of biology-based techniques used to reduce the rate of OTM in humans were described: pharmacological and low-level laser therapy. In the first group, human Relaxin was compared to a placebo and administered orally. It was described as having no effect on the inhibition of OTM in humans after 32 days, while the drug tenoxicam, injected locally, inhibited the rate of OTM by up to 10% in humans after 42 days. In the second group, no statistically significant differences were reported, compared to placebo, for the rate of inhibition of OTM in humans after 90 days of observation when a 860 nm continuous wave GaAlA slow-level laser was used. Conclusions: The currently available data do not allow us to draw definitive conclusions about the use of various pharmacological substances and biology-based therapies in humans able to inhibit or decrease the OTM rate. There is an urgent need for more sound well-designed randomized clinical trials in the field.

Abstract. Obesity is related to increase in the incidence of morbidity and mortality. Studies have suggested anti-obesity properties of garlic; however, results are inconsistent. This systematic review and meta-analysis is done to summarize the data obtained from available randomized clinical trials on the effect of garlic supplementation on body weight, Body Mass Index (BMI), and Waist Circumference (WC). The online databases of Scopus, PubMed, Google Scholar and Cochrane library were searched until March 2018 for related publications using relevant keywords. Effect sizes of eligible studies were pooled using random-effects models. Cochran’s Q-test and I2 index were used for assessing heterogeneity. We found 1241 records in our initial search, of which 13 randomized clinical trials (RCTs) with 15 treatment arms were included. Pooled analysis showed that garlic administration might significantly decrease WC (Weighed Mean Difference (WMD): −1.10 cm, 95% CI: −2.13, −0.07, P = 0.03, I2 = 0%). However, garlic intervention had no significant effect on body weight (WMD): −0.17 kg, 95% CI: −0.75 to 0.39, P = 0.54, I2 = 0%) and BMI (WMD: −0.17 kg/m2, 95% CI: −0.52, 0.16, P = 0.30, I2 = 44.5%) as compared to controls. From Subgroup analysis, it was ascertained that the effect of garlic supplementation on BMI was significant in trials with duration < 12 weeks (WMD: −0.58 kg/m2, 95% CI: −1.08, −0.08, I2 = 19.8%, P = 0.02) compared to those with higher duration (>12 weeks). The current meta-analysis results suggest that garlic supplementation seems to reduce waist circumference unlike body weight and BMI.

Objective: Recent trial studies have found that resveratrol supplementation beneficially reduces oxidative stress marker, but, there is no definitive consensus on this context. The present systematic review and meta-analysis aimed to investigate the effect of resveratrol supplementation on oxidative stress parameters. Methods: We searched databases of Pubmed, Scopus and Cochrane Library up to December 2018 with no language restriction. Studies were reviewed according to preferred reporting items for systematic reviews and meta-analyses (PRISMA) and Cochrane handbook. To compare the effects of resveratrol with placebo, weighted mean difference (WMD) with 95% confidence intervals (CI) were pooled based on the random-effects model. Results: Among sixteen clinical trials, we found that resveratrol supplementation increased GPx serum levels significantly (WMD: 18.61; 95% CI: 8.70 to 28.52; P<0.001) but had no significant effect on SOD concentrations (WMD: 1.01; 95% CI: -0.72 to 2.74; P= 0.25), MDA serum levels (WMD: -1.43; 95% CI: -3.46 to 0.61; P = 0.17) and TAC (WMD: -0.09; 95% CI: -0.29 to 0.11; P = 0.36) compared to placebo. Finally, we observed that resveratrol supplementation may not have a clinically significant effect on oxidative stress. Conclusion: However, the number of human trials is limited in this context, and further large prospective clinical trials are needed to confirm the effect of resveratrol supplement on oxidative stress markers.

Abstract Background Virtual reality therapy has been shown to be an excellent alternative to non-pharmacological treatment for the control of burn pain. Objective To evaluate the effects of virtual reality therapy on pain control in people who have suffered burns published in the scientific literature. Method Systematic review carried out as recommended by Cochrane®. The search was carried out in the Embase, PubMed, Lilacs and Cochrane Library databases, in the period from March 2021. Randomized clinical trials were included without language restriction and year of publication. The risk of bias was assessed using the Cochrane® tool. Results Of the 3755 articles found, only 17 articles were selected for reading in full. Of these, only four articles met the inclusion criteria. The results of the studies showed that the use of virtual reality therapy reduced the intensity of pain in children and adolescents with burns, despite the fact that most results are not statistically significant. No selected study had a high risk of bias. Conclusions Virtual reality therapy has been shown to be effective in controlling pain, reducing the time spent thinking about it and greater distraction during the procedures. However, most randomized clinical trials results were not statistically significant in at least one of the moments when pain was assessed. It is noteworthy that randomized clinical trials are still necessary to administer virtual reality therapy, especially in adults.

Abstract Objective This systematic review aimed to evaluate the effectiveness of different interventions at reducing pain-related fear in people with fibromyalgia and to analyze whether the included trials reported their interventions in full detail. Design Systematic review. Setting No restrictions. Methods The Cochrane Library, CINAHL, EMBASE, PsycINFO, PubMed, and Scopus were searched from their inception to April 2020, along with manual searches and a gray literature search. Randomized clinical trials were included if they assessed pain-related fear constructs as the primary or secondary outcome in adults with fibromyalgia. Two reviewers independently performed the study selection, data extraction, risk-of-bias assessment, Template for Intervention Description and Replication (TIDieR) checklist assessment, and grading the quality of evidence. Results Twelve randomized clinical trials satisfied the eligibility criteria, including 11 cohorts with a total sample of 1,441 participants. Exercise, multicomponent, and psychological interventions were more effective than controls were in reducing kinesiophobia. However, there were no differences in decreasing kinesiophobia when self-management and electrotherapy were used. There were also no differences between groups with regard to the rest of the interventions and pain-related constructs (fear-avoidance beliefs, fear of pain, and pain-related anxiety). However, a serious risk of bias and a very serious risk of imprecision were detected across the included trials. This caused the overall certainty of the judged evidence to be low and very low. Additionally, the included trials reported insufficient details to allow the full replication of their interventions. Conclusions This systematic review shows that there are promising interventions, such as exercise, multicomponent, and psychological therapies, that may decrease one specific type of fear in people with fibromyalgia, i.e., kinesiophobia. However, because of the low–very low certainty of the evidence found, a call for action is needed to improve the quality of randomized clinical trials, which will lead to more definitive information about the clinical efficacy of interventions in this field.

Objectives. This meta-analysis was conducted to compare the complication rates between arm and chest ports in patients with breast cancer. Design and Data Sources. PubMed, Embase, Cochrane library, Chinese National Knowledge Infrastructure (CNKI), and Wanfang database were used to perform a systematic review and meta-analysis of publications published from the inception of the database to 11, October 2019. Our search generated a total of 22 articles published from 2011 to 2019, including 6 comparative studies and 16 single-arm articles, involving 4131 cases and 5272 controls. Single-arm studies combined with comparative studies were also pooled and analyzed. Finally, subgroup analysis was performed to compare the rates of infection and thrombosis between these two ports. Eligibility Criteria. Included articles were research studies comparing complication rates of arm ports with chest ports in patients with breast cancer. Any review or meta-analysis article would be removed. Data Extraction and Synthesis. Demographic data and information for the following analysis were extracted. DerSimonian and Laird random effect meta-analysis was conducted to analyze comparative studies while Begg’s and Egger’s tests were used for assessment of publication bias. Meta-regression analysis was performed to explain the sources of heterogeneity. Results. There was no difference in the risk of overall complications between arm and chest ports for comparative studies (P=0.083). While results of pooled comparative and single-arm studies indicated that arm port would increase the overall complication risks with RR of 2.64, results of the subgroup analysis showed that there was no difference in the risk of catheter-related infection between these two ports. However, arm port might be associated with the higher thrombosis rates compared with chest port according to the results of the analysis for only comparative studies (RR = 2.23, P=0.041) as well as pooled comparative and single-arm studies (RR = 1.21, P=0.029). Conclusions. This study indicated that the arm port might increase the risk of overall complication risks as well as the risk of catheter-related thrombosis compared with the chest port. However, these reported findings still need to be verified by large randomized clinical trials.
