Dimopoulou E, Baysan A. Effect of topical applications containing surface pre-reacted glass-ionomer filler on dental hard tissues-A systematic review. J Dent 2024; 147:104904. [PMID: 38442802 DOI: 10.1016/j.jdent.2024.104904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Revised: 02/06/2024] [Accepted: 02/26/2024] [Indexed: 03/07/2024] Open
Abstract
OBJECTIVES The objective of this systematic review was to assess the efficacy of topical applications containing surface pre-reacted glass-ionomer filler on dental hard tissues. DATA SOURCES A comprehensive literature search was conducted in PubMed, MEDLINE, Embase, Scopus, ClinicalTrials.gov, Lilacs and Cochrane Central Register of Controlled Trials (until 15.08.2022). Google and Open Grey were used to search for grey literature and handsearching was conducted. STUDY SELECTION Clinical and in vitro studies conducted on human adult teeth were considered eligible without date and language restrictions. The electronic database generated 2,488 results. In total, 227 studies were found to be relevant from which 71 duplicates were removed. Title and abstract screening were then conducted, and a total of 33 studies met the inclusion criteria were assessed for full text screening. Two authors concluded that 11 studies satisfied the eligibility criteria. In vitro studies were evaluated using an accepted quality assessment tool for dental studies. Cochrane risk of bias tool was used for quality assessment of clinical randomised studies, whilst ROBINS-I tool was used for non-randomised studies. RESULTS Nine in vitro and only two non-randomised clinical trials were reported to meet the eligibility criteria. Results were grouped and analysed separately according to the study design. Different modes of surface pre-reacted glass-ionomer filler delivery were reported in the included studies. Three studies tested the effect of surface pre-reacted glass-ionomer filler containing toothpastes, whilst three studies investigated the effect of polishing pastes with surface pre-reacted glass-ionomer filler, three studies used eluates as surface pre-reacted glass-ionomer filler delivery method and two studies reported the effect of the coatings. The effect of those vehicles was tested on enamel, dentine or oral biofilm. Each study was analysed individually, and heterogeneity was detected among in vitro and clinical studies. Half of the in vitro studies were medium risk, whilst three were low and two studies presented with high risk. In clinical trials, outcome, confounding, selection biases were reported. Meta-analysis was therefore unable to be carried out. CONCLUSION Regardless of the mode of delivery and type of studies, all included studies demonstrated the efficacy of surface pre-reacted glass-ionomer filler containing topical applications to inhibit demineralisation of dental hard tissues at a dose dependant manner. Antimicrobial properties towards cariogenic species were also reported. CLINICAL SIGNIFICANCE Surface pre-reacted glass-ionomer filler containing topical applications may serve as potential caries preventive and cariostatic tools. The systematic review registered in PROSPERO, International prospective register of systematic reviews, No. CRD42022347130.

Multiple-Ion Releasing Bioactive Surface Pre-Reacted Glass-Ionomer (S-PRG) Filler: Innovative Technology for Dental Treatment and Care. J Funct Biomater 2023; 14:jfb14040236. [PMID: 37103326 PMCID: PMC10142353 DOI: 10.3390/jfb14040236] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Revised: 04/12/2023] [Accepted: 04/19/2023] [Indexed: 04/28/2023] Open
Abstract
Surface Pre-Reacted Glass-ionomer (S-PRG) filler, which releases strontium (Sr2+), borate (BO33-), fluoride (F-), sodium (Na+), silicate (SiO32-), and aluminum (Al3+) ions at high concentrations, is a unique glass filler that are utilized in dentistry. Because of its multiple-ion releasing characteristics, S-PRG filler exhibits several bioactivities such as tooth strengthening, acid neutralization, promotion of mineralization, inhibition of bacteria and fungi, inhibition of matrix metalloproteinases, and enhancement of cell activity. Therefore, S-PRG filler per se and S-PRG filler-containing materials have the potential to be beneficial for various dental treatments and care. Those include restorative treatment, caries prevention/management, vital pulp therapy, endodontic treatment, prevention/treatment of periodontal disease, prevention of denture stomatitis, and perforation repair/root end filling. This review summarizes bioactive functions exhibited by S-PRG filler and its possible contribution to oral health.

J Dent 2023; 131:104445. [PMID: 36773742 DOI: 10.1016/j.jdent.2023.104445] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Revised: 01/21/2023] [Accepted: 02/03/2023] [Indexed: 02/11/2023] Open
Abstract
OBJECTIVE To evaluate the antimicrobial potential of silver nanoparticles (Ag NPs) synthesized using three different routes (ultraviolet light, Turkevich, and green chemistry method using Glycine max extract) associated with COREGA® denture powder adhesive. METHODS Heat-cured acrylic resin specimens were treated with different Ag NPs associated with the adhesive (AD + Ag UV, AD + Ag Turk, and AD + Ag Gm groups). As controls, the specimens were treated with a combination of adhesive and nystatin (AD + Nyst group), only adhesive (AD group), or submerged on the surface of the specimens (PBS group). After the treatments, biofilms of C. albicans developed for 3, 6, and 12 h on the specimen surfaces. The biofilm was quantified using colony-forming units per milliliter, colorimetric assay, and confocal laser scanning microscopy. RESULTS Regardless of the period, we observed an inhibition of fungal load and a reduction in metabolic activity and biofilm mass in the resin specimens treated with the combinations AD/Ag NPs, compared to AD and PBS. The antimicrobial action of the AD + Turk and AD + Ag Gm groups was similar than that for the AD + Nyst group in all periods and viability tests, except for the biofilm mass (12 h). CONCLUSIONS The COREGA® adhesive with Ag NPs, mainly those synthesized using the Turkevich and Glycine max methods, showed excellent antimicrobial activity against C. albicans biofilms, maintained for up to 12 h. CLINICAL SIGNIFICANCE The association of Ag NPs to the adhesive can add preventive or therapeutic effects against denture stomatitis, to this prosthetic material.

Effect of Particle Sizes and Contents of Surface Pre-Reacted Glass Ionomer Filler on Mechanical Properties of Auto-Polymerizing Resin. Dent J (Basel) 2023; 11:dj11030072. [PMID: 36975569 PMCID: PMC10047318 DOI: 10.3390/dj11030072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Revised: 02/24/2023] [Accepted: 02/28/2023] [Indexed: 03/08/2023] Open
Abstract
Herein, the mechanical properties of an auto-polymerizing resin incorporated with a surface pre-reacted glass ionomer (S-PRG) filler were evaluated. For this, S-PRG fillers with particle sizes of 1 μm (S-PRG-1) and 3 μm (S-PRG-3) were mixed at 10, 20, 30, and 40 wt% to prepare experimental resin powders. The powders and a liquid (powder/liquid ratio = 1.0 g/0.5 mL) were kneaded and filled into a silicone mold to obtain rectangular specimens. The flexural strength and modulus (n = 12) were recorded via a three-point bending test. The flexural strengths of S-PRG-1 at 10 wt% (62.14 MPa) and S-PRG-3 at 10 and 20 wt% (68.68 and 62.70 MPa, respectively) were adequate (>60 MPa). The flexural modulus of the S-PRG-3-containing specimen was significantly higher than that of the S-PRG-1-containing specimen. Scanning electron microscopy observations of the specimen fracture surfaces after bending revealed that the S-PRG fillers were tightly embedded and scattered in the resin matrix. The Vickers hardness increased with an increasing filler content and size. The Vickers hardness of S-PRG-3 (14.86–15.48 HV) was higher than that of S-PRG-1 (13.48–14.97 HV). Thus, the particle size and content of the S-PRG filler affect the mechanical properties of the experimental auto-polymerizing resin.

Abstract
Although a surface pre-reacted glass ionomer (S-PRG) exerts a suppressive effect on Candida albicans (C. albicans) activity and growth, its influence on the expression of the lipase gene (LIP) family including LIP1-LIP10, an indicator of clinical infection, has not yet been investigated. Therefore, in this study, we evaluated the effect of S-PRG filler eluates on LIP expression in C. albicans using real-time reverse-transcription polymerase chain reaction. Candida albicans was treated with an S-PRG filler diluted at ratios of 1:32 and 1:64 for 24 h at 37°C. The diluted S-PRG filler eluates (1:32) suppressed lipase activity in C. albicans by downregulating LIP5 (0.54±0.25 relative to that of the control) and LIP8 (0.35±0.074) expression after 24 h, which corresponded with decreased lipase activity. At a dilution factor of 1:64, there was no significant difference in LIP expression. Thus, the S-PRG filler eluate has potential to suppress fungal activity by downregulating LIP expression.

Abstract
The aim of the study was to examine the applicability of bioactive and antibacterial nanoparticles to an experimental adhesive. The adhesive (60 wt% BisGMA, 15 wt% TEGDMA, 25 wt% HEMA) was mixed with combinations of 5 wt% methacryl-functionalized polyhedral oligomeric silsesquioxane (MA-POSS) and one kind of bioactive/antibacterial nanoparticles: 1 wt% core-shell silica-silver nanoparticle (SiO2@Ag), 1 wt% bioactive glass with bismuth (BAG-Bi) or 1 wt% calcium phosphate (CAP). Pure adhesive served as control. The physicochemical (degree of conversion (DC), linear shrinkage (LS), shear and complex viscosity, water sorption (WS), sol fraction (SF)), biological (antimicrobial effect) and bioactive (mineral precipitation) properties were investigated. DC and LS remained unchanged. The combination of BAG-Bi/MA-POSS resulted in a significantly increased WS and SF compared to control. In addition, the combination of CAP/MA-POSS slightly increased the shear viscosity of the adhesive. The addition of the nanoparticles did not influence the antimicrobial effects compared to the pure adhesive. Improved mineral inducing capacity could be detected in all nanoparticle combinations. The combination of bioactive and/or antibacterial nanoparticles showed improved mineral inducing capacity, but no antibacterial properties. The material properties were not or only slightly affected.
