Development of New Experimental Dental Enamel Resin Infiltrants—Synthesis and Characterization

Abstract

The aim of the present study was to obtain experimental infiltration materials, intended for the treatment of dental white spots, and to investigate them. Two series of infiltrants (P1–P6)/(P1F–P6F) were obtained, based on different monomer mixtures, without/with glass filler (with fluoride release ability). Each infiltrant from the second series contained the same amount of glass powder, and each infiltrant from the (P–PF) group contained the same resin composition. The characteristics of the experimental infiltrants were investigated by degree of conversion (DC), mechanical strength, water sorption (WS), and fluoride release, in addition to residual monomer for (P1F–P6F) infiltrants. The results were compared with those obtained for commercial Icon infiltrant. For the experimental infiltrants, without/with filler, the recorded DC was in the range of 58.27–89.70%/60.62–89.99%, compared with Icon (46.94%) 24 h after polymerization. The release of fluoride depends on the permeability of the polymer matrix, with respect to the water sorption, which may help to diffuse ions in the storage medium but which can also influence the release of residual monomers. The highest flexural strengths were recorded for the (TEGDMA/HEMA/Bis-GMA) infiltrants (133.94 ± 16.389 MPa/146.31 ± 7.032 MPa). The best experimental infiltrants were P2 and P2F (Bis-GMA/HEMA/TEGDMA).

Novel dental resin infiltrant containing smart monomer dodecylmethylaminoethyl methacrylate

“…The result demonstrated that the modification did not affect the mechanical properties of resin infiltrant ( p > 0.05). In detail, flexural strength of the resin infiltrant was around 120-130 MPa, while the elastic modulus was about 4 GPa, which were similar to other results ( Prodan et al., 2022 ). The DMAEM could covalently grafted to resin infiltrant by reaction of acrylate groups with methacrylate groups, yielding the non-release antibacterial dental material.…”

“…According to the study published before, the experimental resin infiltrant contains bisphenol-Adiglycidyl methacrylate (BisGMA, Esstech; Essington, PA, USA), triethylene glycol dimethacrylate (TEGDMA, Esstech; Essington, PA, USA), and a light cure initiator system based on camphorquinone (CQ) and ethyl 4-N,N-dimethylaminobenzoate (4E) ( Hashemian et al., 2021 ; Prodan et al., 2022 ). DMAEM was mixed with the experimental resin infiltrant in the dark, at a DMAEM mass fraction of 1.25%, 2.5%, 5% and 7.5%, respectively ( Table 1 ).…”

Resin Infiltration of Non-Cavitated Enamel Lesions in Paediatric Dentistry: A Narrative Review

“…A similar outcome was observed by Prodan et al [ 127 ] using the fluoride-releasing glass filler, where incorporation of the filler improves the DC and strength of the material and inhibits demineralisation through the fluoride-releasing effect. However, contrasting findings were reported by Sfalcin et al [ 128 ] in terms of water sorption and solubility of their experimental resin containing 25% ethoxylated bisphenol A dimethacrylate (BisEMA) and 75% TEDGMA doped with either HAP and BAG.…”

Development of nanohybrid dental composite containing mesoporous carrier silica particles: Synthesis particles, determination of fluoride adsorption capacities, and addition of the composite

“…Compared to other monomers, BISGMA hardened the polymeric matrix formed after polymerization. [30][31][32] Polymerization of the UDMA main monomer in the polymeric matrix resulted in more flexible material. [33] The high-flexural strength and lowstandard deviation were obtained in the ([40:40]:20) ratio as a result of the favorable reactivity, viscosity, and processability that TEGDMA monomer imparted to the UDMA: BISGMA main monomer pair.…”
