“…Another minimal approach regarding the repair of resin composite restorations without silane coupling pretreatment has also been reported [23]. Furthermore, Akimoto et al [24] reported that silane coupling treatment is not necessary for the adhesion of resin composites, depending on the composition of the fillers, owing to the chelating reaction between the acidic monomer and the Sr and Ba alkaline-earth metal ions. AB (a self-etching primer) contains an acidic monomer, while the CRs (BeautiCore LC) contain a S-PRG filler, which itself contains strontium as a glass component.…”

Purpose:The recent development of enamel-colored translucent zirconia makes it a viable material to produce crowns. However, to achieve a sufficient surface roughness for bonding, alumina particle abrasion must be employed. In this study, the effects of particle abrasion on the surface roughness of zirconia and the effects of sample pretreatment on the bond strength between zirconia and a composite resin core were investigated and compared to optimize the surface treatment conditions. Methods: Zirconia specimens were abraded with alumina particles and bonded to trial composite resin cores using a dualcure composite luting agent and either an alumina-zirconia adhesive primer and/or a porcelain primer. The particle abraded zirconia surface was observed via laser scanning microscopy, and the roughness was evaluated qualitatively. Results:The peak-to-valley roughness, arithmetic mean height, root mean square height, and skewness parameter values significantly increased after particle abrasion. The bond strength was greater when the adhesive primer was applied to the zirconia specimens, and when the porcelain primer and a self-etching primer were applied to the composite resin cores, compared with specimens prepared without primers. With a self-etching primer, however, the porcelain primer played no role in increasing the bond strength. Conclusion:The combination of particle abrasion and a suitable primer is recommended to improve the bond strength between zirconia and the composite resin core. Moreover, the chemical surface treatment with a self-etching primer was more effective for adhesion than the silane coupling of the composite resin fillers.

“…Nakase et al [37] reported that S-PRG filler-containing CAD/CAM resin composite blocks demonstrated acceptable physical properties and wear performance for clinical use. Moreover, an S-PRG filler-containing CAD/CAM resin composite crown is advantageous for primary tooth restoration because it can be cemented using a conventional glass-ionomer cement through the chelation reaction between Sr and polycarboxylic acid [38].…”

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.

“…The FL-Bond II primer is an acetone-free adhesion promoting monomer with no incorporation of HEMA [25]. This primer contains ethanol, pure water, a phosphonic acid monomer (6-MHPA), and a carboxylic acid monomer (4-AET) [10,26]. The bonding contains 1,6bis(methacr yloxy-2-ethoxy-carbonylamino)-2,4,4trimethylhexane (UDMA), HEMA, TEGDMA and S-PRG filler (surface pre-reacted glass-ionomer) [27].…”

The aim of this work was to reduce microleakage in giomer restorations by using innovative materials in both adhesive systems and light-cured dental giomer. Two adhesive systems with different primers were investigated. The innovative compounds in the primers were acrylic acid (AA)/itaconic acid (IA) copolymer modified with methacrylic groups and AA/IA/N-acryloyl-L-leucine copolymer grafted with methacrylic groups. In addition, the investigated new giomer G contains a pre-reacted glass based on the latter copolymer. The commercial Beautifil II giomer and the FL-Bond II adhesive system were used for comparison. Microleakage was evaluated by determining the scores and percentages of dye penetration lengths after thermocycling of a series of light-cured dental giomer restorations performed on 42 premolars extracted for orthodontic reasons. A lower microleakage value was recorded for the adhesive system containing the AA/IA/N-acryloyl-L-leucine copolymer grafted with methacrylic groups than for the commercial adhesive, which was in substantial agreement with SEM and AFM investigations. In this case, remarkable dentin sealing and a strong adhesion at the giomer restoration�tooth interface was observed, and the innovative adhesive was proven to be promising for dental applications.
