Review
Self-adhesive resin cements (SARCs) are used because of their mechanical properties, ease of cementation protocols, and lack of requirements for acid conditioning or adhesive systems. SARCs are generally dual-cured, photoactivated, and self-cured, with a slight increase in acidic pH, allowing self-adhesiveness and increasing resistance to hydrolysis. This systematic review assessed the adhesive strength of SARC systems luted to different substrates and computer-aided design and manufacturing (CAD/CAM) ceramic blocks. The PubMed/MedLine and Science Direct databases were searched using the Boolean formula [((dental or tooth) AND (self-adhesive) AND (luting or cement) AND CAD-CAM) NOT (endodontics or implants)]. Of the 199 articles obtained, 31 were selected for the quality assessment. Lava Ultimate (resin matrix filled with nanoceramic) and Vita Enamic (polymer-infiltrated ceramic) blocks were the most tested. Rely X Unicem 2 was the most tested resin cement, followed by Rely X Unicem > Ultimate > U200, and μTBS was the test most used. The meta-analysis confirmed the substrate-dependent adhesive strength of SARCs, with significant differences between them and between SARCs and conventional resin-based adhesive cement (α < 0.05). SARCs are promising. However, one must be aware of the differences in the adhesive strengths. An appropriate combination of materials must be considered to improve the durability and stability of restorations.

Meta-Analysis Review
To investigate whether flash-free adhesive ceramic brackets (FFA) have a better clinical performance than conventional adhesive ceramic brackets (CVA) in patients undergoing multi-bracket orthodontic treatment. PubMed, CENTRAL, Web of Science, Scopus, Embase, CNKI and Grey-literature were searched without restrictions up to January 2022. Both randomized controlled trials (RCTs) and controlled clinical trials (CCTs) were included. Risk of bias assessment was performed using the RoB 2.0 and ROBINS-I cochrane risk of bias tools. Eight articles, for seven studies, were included in this systematic review, and four split-mouth trials (SMT) were included in the meta-analysis. A random-effects meta-analysis found a statistically significant faster bonding time with FFA (mean difference [MD] = -93.85 seconds/quadrant, P = .002, 2 SMT), and no statistically significant difference regarding bracket failure rate at 6 months (risk ratio [RR] = 1.05; P = .93, 3 SMT), adhesive removal time (MD = -18.26 seconds/quadrant, P = .50, 2 SMT), and amount of remnant adhesive (MD = -0.13/bracket, P = .72, 2 SMT) between FFA and CVA. No difference (P > .05, 3 SMT) was found in enamel demineralization and periodontal measurements. CVA showed a statistically significant higher debonding pain score (P = .004, 1 SMT). Both flash-free and conventional adhesive ceramic brackets had a similar clinical performance, except for the faster bonding with FFA. Further, well-designed clinical trials are still required.

Meta-Analysis
Efficacy of adhesive strategies for restorative dentistry: A systematic review and network meta-analysis of double-blind randomized controlled trials over 12 months of follow-up.
PURPOSE
The efficacy of etch-and-rinse, selective enamel-etching, and self-etching protocols for universal adhesives in follow-ups of over 12 months was compared in a network meta-analysis.
STUDY SELECTION
Randomized controlled trials (RCTs) published from 1998 to 2022 that compared marginal staining, marginal adaptation, retention and fractures, post-operative sensitivity, or recurrence of caries that took place over 12-months post-restoration were selected. A network meta-analysis determined the performance of each adhesive protocol.
RESULTS
After screening 981 articles, 16 RCTs were subjected to data extraction. Of which, 674 patients with 2816 restorations, were included in the network meta-analysis. The pooled risk of marginal discoloration following self-etching was significantly higher than that following etch-and-rinse at over 12, 24, and 36 months, which was time-dependent. The pooled risks of unfavorable marginal adaptation and unfavorable retention and fractures following self-etching were also significantly higher than that following etch-and-rinse, with the rates of unfavorable retention and fractures in non-carious cervical lesions increasing in a time-dependent manner. The pooled risks of marginal discoloration, unfavorable marginal adaptation, retention and fractures were similar between etch-and-rinse and selective enamel-etching protocols. Post-operative hypersensitivity and recurrence of caries were not significantly different among etch-and-rinse, selective enamel-etching, and self-etching protocols.
CONCLUSIONS
In follow-ups over 12 months, esthetic and functional outcomes of restorations completed with an etch-and-rinse adhesive protocol were superior to the ones achieved with a self-etching strategy without selective enamel-etching. Selective enamel etching is recommended for self-etching systems. Biological responses were similar for all three adhesive strategies.

Meta-Analysis
OBJECTIVE
To evaluate the adhesion of universal adhesive systems to the dentin of noncarious cervical lesions (NCCLs) by comparing the etch-and-rinse and self-etch strategies through a systematic review and meta-analysis.
METHODS
Systematic electronic searches were performed by two independent reviewers into the following databases: PubMed/MEDLINE, Scopus, Web of Science, and Cochrane Library until December of 2021. Only randomized clinical trials were selected, comparing etch-and-rinse and self-etch strategies and using universal adhesive systems in NCCLs. This systematic review was conducted according to the PRISMA guidelines and registered into PROSPERO.
RESULTS
After the removal of duplicates, 170 articles were identified. In an initial screening of titles and abstracts, 146 records did not satisfy the inclusion criteria and were, therefore, excluded. Twenty-four studies were eligible for evaluation of the full text, and four were excluded after this step. Finally, 20 randomized clinical trials were included in this systematic review and meta-analysis.
CONCLUSION
This systematic review and meta-analysis revealed that applying universal adhesive systems in the etch-and-rinse strategy could lead to better medium-term (>12 to 36 months) retention of NCCL restorations than the self-etch strategy, as well as resulting in lower percentages of marginal discoloration, marginal adaptation, and secondary caries. However, the use of a self-etching strategy can lead to lower postoperative sensitivity.

BACKGROUND
Intrauterine adhesions (IUAs) are one of the main reproductive system diseases in women worldwide. Fusion between the injured opposing walls leads to partial-to-complete obliteration of the cavity and/or cervical canal. The main clinical manifestations in case of IUAs are menstrual disturbances, cyclic pain and reproductive disorders. The reproductive outcomes of women with IUAs remain limited and inefficient compared to women without IUAs, even after adhesiolysis. An exact understanding of the underlying mechanisms and processes to explain the compromised reproductive performance and outcomes in case of IUAs are lacking.
METHODS
A systematic literature review of MEDLINE-PubMed (1966 to January 2022) and EMBASE (1974 to January 2022) was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies were included if they reported underlying causes, related mechanisms and processes to explain the association between IUAs and impaired reproductive performance, pregnancy and obstetric complications.
RESULTS
After an extensive review of the literature, 58 articles were identified reporting underlying mechanisms to explain the association between IUAs and impaired fertility. Intrauterine scarring influences the process of fertilization, reproductive performance and ultimately reproductive outcome. IUAs can disturb the cervico-utero-tubal sperm transport and result in an avascular and unresponsive endometrium with decreased receptivity and thickness. Abnormal decidualization and abnormal trophoblastic infiltration leads to placental attachment disorders. Moreover, the risk for premature delivery, intrauterine fetal growth restriction and fetal anomalies is increased in case of IUAs.
CONCLUSION
The impact of IUAs on reproductive performance, even after adhesiolysis, is becoming more apparent. The postulated mechanisms to explain the association are related to sperm transport, embryo implantation and placentation. Prevention, by preserving the basal layer of the endometrium is essential. Effective and evidence-based strategies for the prevention of endometrial injury and formation of IUAs, are urgently needed.

Review
INTRODUCTION
Adhesive capsulitis is clinically characterized by the gradual progressive painful loss of active and passive motion caused by the formation of adhesions of the joint capsule. Adhesive Capsulitis of the Hip (ACH) is not a well-explored clinical condition when compared to adhesive capsulitis of shoulder because of the underdiagnosis and rarity of this condition
MATERIALS AND METHODS
Cochrane, Scopus, Pubmed, Embase, and Web of Science databases were searched for original studies on ACH till December 2021 following Cochrane and PRISMA guidelines. Year of publication, authors, number of cases, baseline characteristics of the studies, causes described, presentation, associated conditions, method of diagnosis, treatment to be given, functional outcomes, and complications was extracted from each study.
RESULTS
16 articles were included in this review. 3 of the included studies were retrospective case-control studies, 6 were case series and the remaining 7 were case reports. A total of 224 ACH cases were recorded. Pain and stiffness of the hips were the most common clinical features. Investigations like serology, radiograph, and MRI have been used to rule out other conditions. Arthrography has been used to confirm the diagnosis in 7 studies. Spontaneous recovery is expected in one to two years. Management has been in the form of physiotherapy, intra-articular injection, and arthroscopy.
CONCLUSION
Literature on ACH is limited because of the rarity of the condition. The disease has a favorable prognosis with the possibility of spontaneous recovery. Physiotherapy has been the first line of management. Intractable cases require surgical intervention.

Meta-Analysis Review
PURPOSE
Adhesive small bowel obstruction (ASBO) is one of the most important cause of postoperative morbidity in children who underwent abdominal surgery. Laparoscopic management for ASBO in pediatric patients has been reported. However, its safety and efficacy has not been evaluated in details. The aim of this study is to compare the outcomes of laparoscopy and laparotomy for the treatment of ASBO in children.
METHODS
A systematic review and meta-analysis were performed following the Cochrane Handbook for systematic reviews of intervention and the preferred reporting item for systematic reviews and meta-analysis (PRISMA) and a protocol registered in PROSPERO (CRD42017067914). The primary outcome was the number of intraoperative and postoperative complications. The secondary outcome was length of hospital stay. The risk of bias in non-randomized studies of interventions (ROBINS-I) tool was used to assess the risk of bias. Quality of evidence was summarized using the grades of recommendation, assessment, development and evaluation (GRADE) approach.
RESULTS
We identified three observational studies and no randomized controlled trials. The meta-analysis was done only for the primary outcome. Complications were significantly fewer after laparoscopy compared to laparotomy (Odds ratio = 0.51; 95% CI 0.40-0.66; p < 0.01; I : 0%). The overall risk of bias was considered serious.
CONCLUSIONS
Our results, based on observational studies, indicate that laparoscopy for ASBO was associated with less postoperative complications compared to conventional laparotomy. However, the quality of evidence is very low. A well-controlled study is needed to assess the efficacy of laparoscopy for pediatric patients with ASBO.

Clinical Oral Investigations May 2021A network meta-analysis (NMA) was performed to assess which adhesive strategy is most clinically effective in treating non-carious cervical lesions (NCCLs). (Meta-Analysis)
Meta-Analysis Review
OBJECTIVES
A network meta-analysis (NMA) was performed to assess which adhesive strategy is most clinically effective in treating non-carious cervical lesions (NCCLs).
MATERIAL AND METHODS
Studies were identified by a systematic search of electronic databases including MEDLINE via PubMed, Brazilian Library in Dentistry (BBO), Cochrane Library, EMBASE, Latin American and Caribbean Health Sciences Literature database (LILACS), Scopus, and Web of Science without restrictions on publication year or language. The grey literature was also consulted. Only randomized clinical trials that compared different adhesive strategies in NCCLs in adult patients were included. The risk of bias was evaluated by using the Cochrane Collaboration tool. A random-effects Bayesian mixed treatment comparison model was used to compare adhesive strategies (3ER, 2ER, 2SE, and 1SE) at different follow-up times. The surface under cumulative ranking curve (SUCRA) was estimated for each strategy. Heterogeneity was assessed by using the Cochran Q test and I statistics. The quality of evidence was evaluated using the GRADE approach.
RESULTS
A total of 5058 studies were identified, 66 of which met the eligibility criteria and of these 5 were judged "low" risk of bias and 57 were meta-analyzed. We did not observe significant differences in the NMA analysis for any two pairs of adhesives, except for the shortest follow-up for 2ER vs 3ER. The material 2SE ranked highest, although it differed only slightly from the other bonding strategies.
CONCLUSIONS
No bonding strategy is better than the others.
CLINICAL RELEVANCE
Adhesive efficacy cannot be characterized by its bonding strategy.

Meta-Analysis Review
OBJECTIVE
The aim of this study was to evaluate the efficacy and safety of clonidine adhesive patch for tic disorders (TDs).
METHODS
Medline, Embase, Cochrane central register of controlled trials and Chinese databases of CBM, CNKI were searched from inception to 08.2016 for randomized controlled studies (RCTs), open-label control studies of clonidine adhesive patch versus other medications or/and placebo for TDs. The cochrane Handbook for Systematic Reviews of Interventions was used to guide our study.
RESULTS
Six studies involving 1145 participants were included in this study. Among these studies, two study (N = 513 patients) used placebo as a control and four studies (N = 632 patients) used positive drug controls. The results of meta-analysis suggested that clonidine adhesive patch may be as effective as haloperidol or tiapride for TDs. Adverse events (AEs) were reported in all studies, and the most common AEs of clonidine adhesive patch were rash (8.9%), lightheadedness (8.0%), dry mouth (4.0%). The AEs of clonidine adhesive patch were slight.
CONCLUSION
These data provide moderate quality evidence that clonidine adhesive patch might be an effective and safe treatment option for TDs, and results from further trials are urgently needed to extend the evidence base.

Journal of Dentistry Sep 2021This systematic review and meta-analysis evaluated the effects of non-thermal atmospheric plasma (NTAP) treatment on dentin wetting and adhesive-dentin bond strength. (Meta-Analysis)
Meta-Analysis Review
OBJECTIVES
This systematic review and meta-analysis evaluated the effects of non-thermal atmospheric plasma (NTAP) treatment on dentin wetting and adhesive-dentin bond strength.
DATA/SOURCES
This report followed the PRISMA 2020 statement. Two reviewers conducted literature search of MEDLINE, Web of Science and Scopus databases up to the end of November 2020. Included in vitro studies compared the effect of NTAP on treated dentin of non-carious, intact, extracted human third molar teeth with different control groups. Studies with no adequate methods, missing data, lack of control group, or those using animal teeth were excluded. The random effects model was used to summarize the treatment effect with standardized mean difference (SMD) and 95% CI. Risk of bias was assessed using the custom Cochrane Collaboration's tool.
STUDY SELECTION/RESULTS
Seventeen studies met inclusion criteria. The effects on dentin wetting were reported in favor of NTAP (SMD -5.38; 95% CI [-6.97, -3.78]; p<0.00001; I2=81%). Regarding adhesive-dentin bond strength, statistically significant differences between the NTAP and control group were in favor of NTAP in the short-term (SMD 1.92; 95%CI [1.35, 2.50]; p<0.00001; I2=97%), and long-term (SMD 3.28; 95%CI [2.46, 4.09]; p<0.00001; I2=97%). A limitation of meta-analysis is moderate heterogeneity caused by methodological differences and lack of data, which was evaluated through risk of bias and sensitivity analysis.
CONCLUSIONS
NTAP substantially improves dentin wetting and adhesive-dentin bond strength with 30 seconds exposure time and up to 10 mm tip-to-surface distances being sufficient for positive NTAP effects on bonding efficiency.
FUNDING

CLINICAL SIGNIFICANCE
This systematic review and meta-analysis substantiate potential applicability of NTAP treatment of dentin in improving adhesive bonding clinically. Further research should be based on the optimized parameters such as time and distance with additional refinement of NTAP power.
