“…Only one of the new, commercially available, bioactive RBSs (BeautiSealant) was studied in the included in studies [18,20,38,43,49,51]. It was observed that this bioactive RBS released multiple ions, such as Na, Sr, Al, Si and B, which contributed to its strong enamel remineralization effect [49,51].…”

“…Furthermore, a few studies assessed Sr, sodium (Na), aluminum (Al), silicon (Si) and boron (B) ion release [49,51]. It was noticed that these ions' release was significantly high in the bioactive RBS (BeautiSealant) [20,38,43,49,51]. Nevertheless, one study reported that BeautiSealant released the lowest amount of fluoride [18], and another study stated that there was no significant difference between BeautiSealant and Teethmate F-1 sealants [20].…”

Remineralizing Effects of Resin-Based Dental Sealants: A Systematic Review of In Vitro Studies

The incorporation of remineralizing additives into sealants has been considered as a feasible way to prevent caries by potential remineralization through ions release. Thus, this systematic review aimed to identify the remineralizing additives in resin-based sealants (RBS) and assess their performance. Search strategies were built to search four databases (PubMed, MEDLINE, Web of Science and Scopus). The last search was conducted in June 2020. The screening, data extraction and quality assessment were completed by two independent reviewers. From the 8052 screened studies, 275 full-text articles were assessed for eligibility. A total of 39 laboratory studies matched the inclusion criteria. The methodologies used to assess the remineralizing effect included microhardness tests, micro-computed tomography, polarized-light microscopy, ions analysis and pH measurements. Calcium phosphate (CaP), fluoride (F), boron nitride nanotubes (BNN), calcium silicate (CS) and hydroxyapatite (HAP) were incorporated into resin-based sealants in order to improve their remineralizing abilities. Out of the 39 studies, 32 studies focused on F as a remineralizing agent. Most of the studies confirmed the effectiveness of F and CaP on enamel remineralization. On the other hand, BNN and CS showed a small or insignificant effect on remineralization. However, most of the included studies focused on the short-term effects of these additives, as the peak of the ions release and concentration of these additives was seen during the first 24 h. Due to the lack of a standardized in vitro study protocol, a meta-analysis was not conducted. In conclusion, studies have confirmed the effectiveness of the incorporation of remineralizing agents into RBSs. However, the careful interpretation of these results is recommended due to the variations in the studies’ settings and assessments.

“…[18,23] These results can be explained by the quick effect of fluoridereleasing ionomeric materials within the first hours, acting initially at the tooth/material interface and remaining constant at lower concentrations. [30] In addition, prevention of demineralization occurred after aging of the material. Aging by thermocycling, as used in this study, might have contributed to lower bacterial adhesion.…”

Objective: The aim of this study was to evaluate the effect of sealants on the prevention of enamel demineralization and on biofilm metabolic activity. Materials and Methods: Cavity preparations were performed on 45 blocks of bovine teeth (4x4x4 mm) randomly assigned to three groups (n=15): RI-Riva Light Cure®/SDI; EM-Embrace™ WetBond™ Pulpdent Corp.®; and CO-Natural Flow/DFL resin (negative control). The sealed blocks were subjected to thermocycling (500 cycles/30 s). Half of the blocks were covered with acidresistant varnish to create a control area (RI, EM, and CO) and an experimental area (RI-EX, EM-EX, and CO-EX). They were subsequently exposed to Streptococcus mutans biofilm for assessment of demineralization by the Knoop microhardness test (50 g/15 s), at 25, 50, 100, 150, and 200 μm from the interface. In another test, the cylinders of the sealants (4 mmx3 mm) were subjected to the biofilm metabolic activity test. Results: The RI-EX group showed higher microhardness than CO-EX (p<0.05) and less demineralization when compared to RI at all distances. Microbial activity was lower in EM compared to CO, but not statistically significant in relation to RI. Conclusion: Both sealants can inhibit enamel demineralization in the presence of S. mutans biofilm.

Introduction. From the variety of direct restorative dental materials, composite resins are considered as having the most esthetic and functional properties. The conservative preparation, esthetic results, good mechanical qualities and surface finishing properties of dental composites, combined with the protective properties of fluoride from glass-ionomers, led to a new generation of dental materials: the giomers. Objective. The purpose is to review the available literature about the giomers, regarding the chemical composition, handling properties and esthetics, adhesion and microleakage, fluoride releasing and protection offered, clinical indications. Method. The search was carried out using ScienceDirect and PubMed databases with the following keywords: giomer, esthetic properties giomers and fluoride releasing giomers. A total of 232 articles were initially selected, with the following inclusion criteria: full text articles, written in English, with topics on the properties and the clinical implications of giomers. Papers presented as abstract were not included. In the next step, review articles, duplicates, and articles in other languages were removed; as a result, a total of 44 sources published between 2004 and 2017 were selected. Results. The selected articles referred to the following aspects about the giomers: chemical composition (8 articles), adhesion and microleakage (10 articles), fluoride releasing and pulp protection (15 articles), clinical indications (6 articles), effects of additional treatments and dietary habits (11 articles).
