Purpose. The objective of this systematic review is to compare results concerning the properties of adhesion, roughness, and hardness of dental liners obtained in the last ten years. Methods. Searches on the databases LILACS, PubMed/Medline, Web of Science, and Cochrane Database of Systematic Reviews were supplemented with manual searches conducted between February and April of 2018. The inclusion criteria included experimental in vitro and in vivo, clinical, and laboratory studies on resilient and/or hard liners, assessment of hardness, roughness, and/or adhesion to the denture base, and physical/mechanical changes resulting from the disinfection process and changes in liners’ composition or application. Results. A total of 406 articles were identified and, from those, 44 are discussed. Twenty-four studies examined the bond strength, 13 surface roughness, and 19 the hardness. Of these 44 studies, 12 evaluated more than one property. Different substances were used in the attempt to improve adhesion. Considering roughness and hardness, the benefits of sealants have been tested, and the changes resulting from antimicrobial agents’ incorporation have been assessed. Conclusion. Adhesion to the prosthesis base is improved with surface treatments. Rough surfaces and changes in hardness compromise the material’s serviceability.

Glycemic Profile

This study aimed to perform a systematic review and meta-analysis of the glycemic index (GI) of gluten-free bread (GFB) and its main ingredients. The systematic review followed PRISMA guidelines, using seven electronic databases (PubMed, EMBASE, Scopus, Science Direct, Web of Science, gray literature research with Google Scholar, and patents with Google Patent tool), from inception to November 2020. Eighteen studies met the inclusion criteria evaluating 132 GFB samples. Five articles tested GI in vivo, eleven in vitro; and two studies tested both methods. The analysis showed that 60.7% (95% CI: 40.2–78.1%) of the samples presented high glycemic indexes, evidencing a high glycemic profile for GFB. Only 18.2% (95% CI: 11.7–27.2%) of the bread samples presented in the studies were classified as a low GI. Meta-analysis presented moderate/low heterogenicity between studies (I2 = 61% and <1% for both high and low GIs) and reinforced the proportion of high GIs. Lower GIs were found in formulations based on Colocasia esculenta flour or enriched with fiber, yogurt and curd cheese, sourdough, psyllium, hydrocolloids, enzymes, fructans, and resistant starch, highlighting the efficacy of these ingredients to lower GFBs’ GI. GFB tends to present high GI, impacting the development of chronic diseases when consumed.

ABSTRACT Objective: To use a systematic review to determine which materials and technique/protocol present the highest success rate in bonding brackets to porcelain surfaces. Materials and Methods: Different databases were searched without limitations up to July 2013. Additionally, the bibliographies of the finally selected articles were hand searched to identify any relevant publications that were not identified earlier. In vitro and in vivo articles were included. Results: No in vivo articles were found that fulfilled the inclusion criteria. A total of 45 in vitro articles met all inclusion criteria. They were published between 2000 to July 2013. Conclusions: The best protocol described in this review is the etching of 9.6% hydrofluoric acid for 1 minute, rinsed for 30 seconds, and then air-dried. The etching of hydrofluoric acid should be followed by an application of silane. Considering the harmful effects of etching with hydrofluoric acid, another appropriate suggestion is mechanical roughening with sandblasting followed by an application of silane.

Introduction: Today we see advances in the use of medicinal plants in the treatment of fungal infections. Curcumin has major antimicrobial, antifungal, antimutagenic, and anticancer activity. This systematic review study is designed to evaluate the effectiveness of curcuminon a dermatophyte fungus, Trichophyton spp. Methods: In this study, antifungal effects of curcumin on the different strains of Trichophytonwereevaluated. For this reason, several databases, including PubMed, Scopus, Web of Science, Embase and Google Scholar were searched systematically in years from1995 to 2020. Only articles with at least English abstracts were evaluated. The syntax was constructed with the combination of some key words along with specific tags used for each of the databases. Results: In this systematic review, studies showed that curcumin has a potent effect on the inhibition of Trichophyton growth. Of the 2,500 studies in the search step, only 11articleswere eligible for survey, 6 of which were on T.rubrum, 3 on T. mentagrophytes, 1 on both T. mentagrophyte and T. rubrum, and 1 on T. longifusus. Conclusion: Today, due to an increase in drug resistance to antifungal agents, plant extracts can be a good alternative in controlling fungal diseases. Curcumin and its compounds are effective in inhibiting or reducing Trichophyton infections in vitro and in vivo.

Chitosan is a natural polysaccharide extracted from the shells of crustaceans that has been proposed as a scaffold in tissue engineering. Certain studies have proven a greater osseointegration of titanium surfaces that are functionalized with chitosan. The MEDLINE, CENTRAL, PubMed, and Web of Science databases were electronically searched for in vivo studies. Seven studies met the inclusion criteria. Animal models, implant site, chitosan incorporation methods, and methods of analysis were emphasized. The selected studies were individually discussed regarding the coatings, osseointegration potential, and suitability of the experimental models used, analyzing their limitations. We concluded that chitosan-biofunctionalized titanium surfaces have greater osseointegration capacity that uncoated control titanium alloys.

ABSTRACTThe objective of this systematic review was to evaluate the biocompatibility and interaction of bioceramic materials with animal and human mesenchymal cells in vitro and in vivo and to compare them with mineral trioxide aggregate (MTA). Two independent researchers conducted PubMed/Medline, Web of Science, and Scopus searches to identify studies published in English, without restrictions on year of publication using the following keywords: “root canal sealer,” “root repair material,” “cytotoxicity,” and “bioceramics.” The articles were selected following the PRISMA statement. A total of 1486 titles were identified in the initial search. However, only 18 studies met the inclusion and exclusion criteria. The results showed that bioceramic materials have biological properties similar to those of MTA, including low cytotoxicity as well as promoting cell proliferation and adhesion, low expression of inflammatory cytokines, and reduced pulp inflammation. This systematic review therefore suggests that the choice of repair bioceramic materials or MTA based on biocompatibility should be the professional's decision.

Background: In recent years, more attention has been focused in the practice of both crude extract of medicinal plants, and the screening plant-derived compounds as substitute scolicidal agents during hydatid cyst surgery. The present study was designed to review the protoscolicidal effects of some Iranian herbal medicines against hydatid cyst protoscoleces. Methods: English databases, including PubMed, Google Scholar, Web of Science, EBSCO, Science Direct, and Scopus were searched for publications worldwide related to protoscolicidal effects of Iranian herbal medicines without date limitation so that identify all published articles (in vitro, in vivo, clinical and case-control) have studied. Keywords included “Protoscolicidal”, “Scolicidal”, “Herbal medicines”, “Extract”, “Essential oil”, “Plant”, “In vitro”, and “Iran”. Moreover, the language of data collection was limited to English. Results: In total, 40 papers up to 2020 were included in the present systematic review. The most studies were conducted on protoscolicidal activity of methanolic extracts (17 studies) followed by essential oils (15 studies), and aqueous extract (3 studies). The most commonly used part of herbs were leaves (21 herbs), seeds (8 herbs), and fruit (6 herbs), respectively. Moreover, the most prevalent herbal family was Lamiaceae (6 studies), followed by Apiaceae (5 studies) and Liliaceae (5 studies). Conclusion: Considering the high efficacy of Iranian herbal medicines against hydatid cyst protoscoleces, it can be concluded that Iranian herbal medicines have ability to consider as new alternative protoscolicidal agents during hydatid cyst surgery; however, more clinical studies are required to discover the precise protoscolicida activity of Iranian medicines in animal and human subjects.

Secretome and extracellular vesicles (EVs) are considered a promising option to exploit mesenchymal stem cells’ (MSCs) properties to address knee osteoarthritis (OA). The aim of this systematic review was to analyze both the in vitro and in vivo literature, in order to understand the potential of secretome and EVs as a minimally invasive injective biological approach. A systematic review of the literature was performed on PubMed, Embase, and Web of Science databases up to 31 August 2019. Twenty studies were analyzed; nine in vitro, nine in vitro and in vivo, and two in vivo. The analysis showed an increasing interest in this emerging field, with overall positive findings. Promising in vitro results were documented in terms of enhanced cell proliferation, reduction of inflammation, and down-regulation of catabolic pathways while promoting anabolic processes. The positive in vitro findings were confirmed in vivo, with studies showing positive effects on cartilage, subchondral bone, and synovial tissues in both OA and osteochondral models. However, several aspects remain to be clarified, such as the different effects induced by EVs and secretome, which is the most suitable cell source and production protocol, and the identification of patients who may benefit more from this new biological approach for knee OA treatment.

The use of biological templates for the suitable growth of adipose-derived mesenchymal stem cells (AD-MSC) and “neo-tissue” construction has exponentially increased over the last years. The bioengineered scaffolds still have a prominent and biocompatible framework playing a role in tissue regeneration. In order to supply AD-MSCs, biomaterials, as the stem cell niche, are more often supplemented by or stimulate molecular signals that allow differentiation events into several strains, besides their secretion of cytokines and effects of immunomodulation. This systematic review aims to highlight the details of the integration of several types of biomaterials used in association with AD-MSCs, collecting notorious and basic data of in vitro and in vivo assays, taking into account the relevance of the interference of the cell lineage origin and handling cell line protocols for both the replacement and repairing of damaged tissues or organs in clinical application. Our group analyzed the quality and results of the 98 articles selected from PubMed, Scopus and Web of Science. A total of 97% of the articles retrieved demonstrated the potential in clinical applications. The synthetic polymers were the most used biomaterials associated with AD-MSCs and almost half of the selected articles were applied on bone regeneration.

Significant number of literatures has demonstrated the antiproliferative effect of Zerumbone and its role as anti-angiogenesis. The aims of this systematic review were to assess the anti-cancer effects of Zerumbone and the role of its antiangiogenic properties in treating cancer. Relevant articles were selected based on specific inclusion criteria. Articles chosen for this systematic review were between January 2008 and December 2018. Relevant articles were identified through an extensive search in Science Direct, PubMed, Google Scholar and Scopus. The literature searches of the electronic databases combined the following key words: anti-angiogenic, anticancer, Zerumbone and Zingiber zerumbet. Studies chosen for this review includes the following designs in vitro, in vivo and ex vivo. The initial literature search obtained a total of 352 related records and the final number of studies that met the inclusion criteria in the current review was 43 studies. In vitro studies were the commonest study design. Evidently, Zerumbone demonstrate a potential antiproliferative and antiangiogenic. The antiproliferative activities of Zerumbone was shown to induce by different signalling pathway. Zerumbone through its antiangiogenic effect play a great role in reducing invasion and metastasis. Some selected studies on Zerumbone were found to plague with limitation such as lack of toxic threshold value which may be needed for the clinical trials on this compound.
