“…FMMT intercalated with N -methylformamide (FMMT–NMF) was prepared by the dispersion of a solution of FMMT in DI water (5 g in 5 mL) in N -methylformamide (60 mL, NMF; 473936, Sigma-Aldrich, St. Louis, MO, USA) followed by magnetic stirring at room temperature (25 °C) for 72 h [31]. The solid was collected following centrifugation (10 min at 4000 rpm) and then dried in a vacuum oven at 60 °C to obtain FMMT-NMF as a powder.…”

“…FMMT intercalated with acrylamide (FMMT-AAm) was synthesized by mixing a 12 wt % acrylamide solution (12 g acrylamide, A17157, Alfa Aesar, Ward Hill, MA, USA) in DI water (100 mL) with FMMT-NMF (2 g) under magnetic stirring at room temperature (25 °C) for 24 h. NaF (0.5 g) and a 5 M NaNO 3 buffer (10 mL) were then added and the pH was adjusted to 4 by titration with 12 M HCl or 1 M NaOH [31]. The resulting acidic mixture was then magnetically stirred at room temperature (25 °C) for an additional 24 h followed by centrifugation at 4000 rpm for 10 min; the supernatant was discarded.…”

“…After 14 d of fluoride release, each sample was subjected to sonication (3 × 15 mL DI water for 10 min) to remove any residual fluoride ions on the surface of the MLC samples. The different groups of samples were then placed in 0.2% aqueous NaF (5 mL) at pH 7 for 1 min [31] to determine the recharge ability of the MLC samples containing varying amounts of FMMT-AAm-NaF. The samples were then removed, air-dried, and placed in DI water (5 mL) to repeat the fluoride ion release process over 7 d. The daily fluoride release from this 7 d process was also calculated to determine the cumulative fluoride release amount after recharging.…”

Molar pits and fissures tend to be affected by caries due to cleaning difficulties. As such, the filling of pits and cracks with sealants is common to deter the onset of caries. However, current clinical practices rely on sealants that lack the ability to release and recharge fluoride ions. Thus, we herein report the development of a fluoride—montmorillonite nanocomposite resin that has the potential to provide sustained release of fluoride due to the strong adsorption of fluoride by montmorillonite. X-ray diffractometry, thermogravimetric analysis, and Fourier-transform infrared spectroscopy were employed to confirm the successful insertion of the polymer into the interlayer structure. The mechanical properties (viscosity, hardening depth, hardness, diametral tensile strength, flexural strength, and wear resistance) of the developed composite resin were then examined, and simulation of the oral environment demonstrated a good fluoride ion release and recharge ability for the effective prevention of dental caries. Finally, we demonstrated the non-cytotoxic nature of this material using the water-soluble tetrazolium salt (WST-1) test. We expect that the described fluoride-containing composite resin may become a new clinical option in the near future.

“…After 14 days of fluoride release, residual fluoride ions on the surface of the samples were removed by sonication (three times in 15 mL DI water for 10 min). Subsequently, the samples were placed in a 0.2% NaF solution (5 mL) at pH 7 for 1 min [37] to recharge fluoride ions to the samples. Then, the samples were removed, air-dried and soaked in DI water (5 mL) to repeat the fluoride ion release process over 1 week.…”

Dental caries (tooth decay) is the most frequent oral disease in humans. Filling cavities with a dental restorative material is the most common treatment, and glass ionomer cements are the main fluoride ion release restorative materials. The goal of this study was to develop a restorative compound with superior fluoride ion release and recharge abilities. Previously developed fluorinated bentolite and hydrophobized 3YSZ were used as two different inorganic fillers mixed in a bisphenol A-glycidyl methacrylate (Bis-GMA) matrix. XRD, FTIR, and TGA were used to determine the hydrophobic modification of these two inorganic fillers. In mechanical tests, including diameter tensile strength, flexural strength, and wear resistance, the developed composite resin was significantly superior to the commercial control. A WST-1 assay was used to confirm that the material displayed good biocompatibility. Furthermore, the simulation of the oral environment confirmed that the composite resin had good fluoride ion release and reloading abilities. Thus, the composite resin developed in this study may reduce secondary caries and provide a new choice for future clinical treatments.

“…Xu et al added calcium fluoride nanoparticles (∼56 nm) up to 30% to bionanocomposites and found that the fluoride release was better detected compared to traditional resin counterpart while strength and elastic modulus of the nanocomposite are sustained [63,64]. Because of unique structural of kaolinite, which has high surface area for adsorption of fluoride, kaolinite is considered as an excellent carrier compared with the conventional silica nanoparticle used in conventional composite resins [65]. These polymer-kaolinite bionanocomposites have the potential to provide sustained release of fluoride due to strong adsorption of kaolinite to fluoride during the fabrication process.…”

Multiphasic bionanocomposites have been highlighted in the biotechnology field since they have offered mechanical flexibility during operation. This interest has been increased mainly through polymer/ceramic/metal manipulation techniques and modifications in formulation. Recently, a number of studies on bionanocomposites have been examined due to their favorable mechanical properties and cellular activities when compared to the neat polymers or polymer blends. This paper critically reviews recent applications of bionanocomposites for regeneration of pulp-dentin complex, periodontal ligament, and alveolar bone, and substitute of enamel in dentistry.
