Review
OBJECTIVE
The aim of this study was to review the selection criteria of resin cements for different types of partial coverage restorations (PCRs) and investigate if the type of restorations or restorative materials affect the type of selected resin cement.
MATERIALS AND METHODS
An electronic search (1991-2023) was performed in PubMed, Medline, Scopus, and Google Scholar databases by combinations of related keywords.
RESULTS
A total of 68 articles were included to review the selection criteria based on the advantages, disadvantages, indications, and performance of resin cements for different types of PCRs.
CONCLUSIONS
The survival and success of PCRs are largely affected by appropriate cement selection. Self-curing and dual-curing resin cements have been recommended for the cementation of metallic PCRs. The PCRs fabricated from thin, translucent, and low-strength ceramics could be adhesively bonded by light-cure conventional resin cements. Self-etching and self-adhesive cements, especially dual-cure types, are not generally indicated for laminate veneers.

Review
INTRODUCTION
In a suitable condition, it is important to perform any dental restorative procedure using an operatory field isolated. Then, the aim of this study was to compare the bond strength of composite restorations to dentin affected by any contamination agent through a systematic review.
METHODS
This systematic review was performed following the PRISMA 2020 guidelines. The literature search was conducted until September 2022 by scanning the following databases: Embase, PubMed, Scielo, Scopus, and Web of Science. Manuscripts evaluated the bond strength of resin-based materials to permanent human dentin contaminated with blood or saliva were selected for full-text review. The risk of bias was assessed by the RoBDEMAT tool.
RESULTS
A total of 3750 papers resulted from the search from all databases. After the full-text reading, a total of 62 articles remained for the qualitative analysis. The contamination agents used were blood, saliva, and hemostatic agents. A great variety of protocols were used to contaminate the dentin surface, and the contamination process occurred in several steps of the bonding process, including before and after the etching process, after the primer application and after the adhesive application. Also, several decontamination procedures were tested, including reapplication of the etching material, rinsing with water, chlorhexidine or sodium hypochlorite and reapplication of the adhesive system.
CONCLUSION
Any contamination with blood or saliva impaired the bond strength of resin-based materials to dentin. Decontamination procedures including water-spray and reapplication of the bonding system could revert the impairment produced by the saliva or blood contamination. The use of hemostatic agents as a method of blood decontamination is not recommended.
CLINICAL SIGNIFICANCE
Clinicians should avoid contamination during a bonding procedure, otherwise, a reduction in the bond quality is expected.

UNLABELLED
Aseptic stem loosening after total hip arthroplasty surgery is the commonest complication, whether stem is cemented or uncemented. The aseptic cemented stem loosening has been a challenging problem over the years and a leading cause for revision since the inception of total hip arthroplasty. The objective of systematic review and meta-analysis was to determine the impact of cementing technique on aseptic stem loosening in total hip arthroplasty.
METHODS
Cochrane, CINAHL, Embase, Google scholar, Medline, PubMed were searched in 13 December 2020. Two independent investigators extracted the data and a third investigator's involvement was reached on consensus. A total of 37 studies of revision rate due to aseptic loosening were reviewed by using fixed/random effects size and were grouped by cementing technique and studies' characteristics. The data were analyzed through Meta-Essentials and RStudio.
RESULTS
In revision total hip arthroplasty, retained femoral components revisions rate due to aseptic loosening were recorded in 37 studies involving 6167 cases. Aseptic loosening rate collectively was 5.8% (CI 95%, 0.03-0.08) and mean follow-up of study was 12.5 years. The average follow-up period, mean age at index revision surgery and percentage of aseptic loosening were insignificantly associated with revision rate (≥0.05), in meta-regression univariant analyses.
CONCLUSION
This investigative analysis showed that there is a minimal difference between results of cementing techniques of total hip arthroplasty in femoral components in long-term follow-ups, and usually have a low risk of failure.

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.

Meta-Analysis
BACKGROUND
This systematic review and network meta-analysis aimed to compare the clinical efficacy of bioactive and conventional restorative materials in controlling secondary caries (SC) and to provide a classification of these materials according to their effectiveness.
METHODS
A search was performed in Pubmed, Web of Science, Embase, BBO, Lilacs, Cochrane Library, Scopus, IBECS and gray literature. Clinical trials were included, with no language or publication date limitations. Paired and network meta-analyses were performed with random-effects models, comparing treatments of interest and classifying them according to effectiveness in the permanent and deciduous dentition and at 1-year or 2/more years of follow-up. The risk of bias and certainty of evidence were evaluated.
RESULTS
Sixty-two studies were included in the qualitative syntheses and 39 in the quantitative ones. In permanent teeth, resin composite (RC) (RR = 2.00; 95%CI = 1.10, 3.64) and amalgam (AAG) (RR = 1.79; 95%CI = 1.04, 3.09) showed a higher risk of SC than Glass Ionomer Cement (GIC). In the deciduous teeth, however, a higher risk of SC was observed with RC than with AAG (RR = 2.46; 95%CI = 1.42, 4.27) and in GIC when compared to Resin-Modified Glass Ionomer Cement (RMGIC = 1.79; 95%CI = 1.04, 3.09). Most randomized clinical trials studies showed low or moderate risk of bias.
CONCLUSION
There is a difference between bioactive restorative materials for SC control, with GIC being more effective in the permanent teeth and the RMGIC in the deciduous teeth. Bioactive restorative materials can be adjuvants in the control of SC in patients at high risk for caries.

Meta-Analysis Review
BACKGROUND
The results of vital pulp treatments in permanent teeth have been encouraging. Currently, pulpotomy treatment for permanent teeth primarily utilizes mineral trioxide aggregate (MTA) as the dressing material, followed by calcium hydroxide. While other calcium-silicate-based cements have been suggested for pulpotomy, there is a limited number of studies evaluating their long-term effectiveness.
OBJECTIVES
The objective of this systematic review and meta-analysis was to evaluate the success rate of pulpotomies performed on permanent teeth, comparing the use of ProRoot MTA with that of calcium hydroxide and other bioceramic materials.
METHODS
A comprehensive search was conducted in several electronic databases, including PubMed, Cochrane Library, Scopus, Web of Science, Embase and Science Direct until December 2022. The search was guided by PICOS criteria, including only randomized clinical trials (RCTs) that evaluated the success rate of pulpotomy treatments in permanent teeth using ProRoot MTA in comparison to calcium hydroxide and other bioceramic materials. The quality of the included studies was assessed using the RoB-2 tool to evaluate the risk of bias, and relevant data were extracted and analysed in RevMan software 5.3 using fixed-effect models. The GRADE tool was used to determine the overall quality of evidence.
RESULTS
The initial search retrieved 1072 studies and, after eliminating duplicates, 677 studies were screened and 28 studies were considered for eligibility. In the final selection process, 16 studies were included in the systematic review, with 10 being determined as having a high risk of bias. Pulpotomy showed an overall mean success rate of 92% after 1 year. The meta-analysis indicated a significantly higher success rate for pulpotomies utilizing MTA in comparison with calcium hydroxide, while no significant difference was seen between MTA and calcium-enriched mixture (CEM) or Biodentine. The GRADE assessment revealed an overall low level of evidence for the included studies.
DISCUSSION
Most randomized controlled trials exhibited a significant absence of control over confounding factors.
CONCLUSIONS
This systematic review and meta-analysis demonstrate that pulpotomy is a highly effective treatment for managing permanent teeth. The results indicate that the success rate of pulpotomy using ProRoot MTA is significantly higher than when using calcium hydroxide. However, the certainty of evidence supporting these findings is low, and there is a need for well-designed RCTs to assess the long-term outcomes of pulpotomy using newer bioceramic materials.

Review
OBJECTIVES
The purpose of this systematic review was to analyze the effect of commercially available calcium silicate-based bioactive endodontic cement (BEC) on treatment outcome when used as root repair material in human permanent teeth and to compare it with traditional materials.
METHODS
PubMed, Embase, and Cochrane Library were searched until June 2020. Randomized clinical studies and observational studies with a minimum 1-year follow-up and sample size of at least 20 were included. Risk of bias (ROB) was assessed using Cochrane's ROB tool and the National Institutes of Health Quality Assessment Tool.
RESULTS
Thirty-nine studies were included in the systematic review. Majority of the studies used mineral trioxide aggregate. The pooled success rate for BEC was estimated by a random-effects method as 90.49% (95% confidence interval [CI]: 88.4992.34, = 54%). Eleven studies comparing BEC with traditional materials were included in the meta-analysis. The use of BEC significantly improved the treatment outcome when compared to traditional materials with odds ratio (OR) = 2.15 (95% CI: 1.57-2.96, = 0.8%, = 0.433).
CONCLUSION
Very low-to-moderate-quality evidence suggests that the use of BEC as root repair material enhanced the treatment outcome. High-quality studies are required for the newer BEC to establish their clinical performance. Registration: PROSPERO CRD42020211502.

Review
Are polywave light-emitting diodes more effective than monowave ones in the photoactivation of resin-based materials containing alternative photoinitiators? A systematic review.
OBJECTIVE
This systematic review aimed to analyze if using polywave light-emitting diodes (LED) to photoactivate resin-based materials (resin composites, adhesive systems, and resin cements) containing alternative photoinitiators provide better physicochemical properties than monowave ones.
MATERIAL AND METHODS
Inclusion criteria were in vitro studies that evaluated the degree of conversion, microhardness and flexural strength in resin-based materials containing alternative photoinitiators and light-activated with mono and polywave LEDs. Exclusion criteria were studies that evaluated the physicochemical properties of composites through any material interposed between the LED and the resin composite and studies that exclusively compared different modes and/or light activation times. Selection of studies, data extraction, and risk-of-bias analysis was performed. Data from selected studies were qualitatively analyzed. A systematic search was performed in June 2021 using PubMed/Medline, Embase, Scopus, and ISI Web of Science databases and grey literature without language restriction.
RESULTS
A total of 18 studies were included in the qualitative analysis. Nine studies used diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide (TPO) as an alternative photoinitiator for resin composite. Polywave LED improved the degree of conversion of resin composite compared to monowave in 9 of the included studies. Polywave LED improved the microhardness of resin composite compared to monowave in 7 of the included studies. Polywave LED improved the degree of conversion for 11 studies and microhardness of resin composite compared to monowave for 7 included studies. No differences in the flexural strength medium between poly and monowave LEDs were observed. The evidence was graded as low quality due to the high risk of bias for 11 studies.
CONCLUSION
The existing studies, with their limitations, revealed that the polywave light-emitting diode maximizes activation, resulting in a higher degree of double-bond conversion and microhardness of resin composites containing alternative photoinitiators. However, the flexural strength of these materials is not influenced by the type of light activation device.

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.
