“…In dense composites, formation of capillaries at the interfaces may lead to enhanced dissolution of the glass [47]. Coating bioactive glass particles or fiber with a suitable sizing layer retards the dissolution and increases the adhesion to the polymer [60,61]. Thus, depending on the FRC structure, the additional coating may help in controlling the initial ion release rate from the glasses and thus aid osseointegration of the implant.…”

“…[25] Because of its much greater surface area, sol-gel-derived BAG has the potential to more readily release these ions in composites, and be rechargeable when exposed to topical sources of calcium and fluoride. Furthermore, studies of composites formulated with BAG have shown that the mechanical properties are not significantly compromised by addition of 12 to 15 wt% BAG, [26,27] and the total material loss for a nonsilanated bioglass-contaning composite was not quite 1% after 60 days in DI water. [27]…”

Objectives Materials that are capable of releasing ions such as calcium and fluoride, that are necessary for remineralization of dentin and enamel, have been the topic of intensive research for many years. The source of calcium has most often been some form of calcium phosphate, and that for fluoride has been one of several metal fluoride or hexafluorophosphate salts. Fluoride-containing bioactive glass (BAG) prepared by the sol-gel method acts as a single source of both calcium and fluoride ions in aqueous solutions. The objective of this investigation was to determine if BAG, when added to a composite formulation, can be used as a single source for calcium and fluoride ion release over an extended time period, and to determine if the BAG-containing composite can be recharged upon exposure to a solution of 5,000 ppm fluoride. Methods BAG 61 (61% Si; 31% Ca; 4% P; 3% F; 1% B) and BAG 81 (81% Si; 11% Ca; 4% P; 3% F; 1% B) were synthesized by the sol gel method. The composite used was composed of 50/50 Bis-GMA/TEGDMA, 0.8% EDMAB, 0.4% CQ, and 0.05% BHT, combined with a mixture of BAG (15%) and strontium glass (85%) to a total filler load of 72% by weight. Disks were prepared, allowed to age for 24 h, abraded, then placed into DI water. Calcium and fluoride release was measured by atomic absorption spectroscopy and fluoride ion selective electrode methods, respectively, after 2, 22, and 222 h. The composite samples were then soaked for 5 min in an aqueous 5,000 ppm fluoride solution, after which calcium and fluoride release was again measured at 2, 22, and 222 h time points. Results Prior to fluoride recharge, release of fluoride ions was similar for the BAG 61 and BAG 81 composites after 2 h, and also similar after 22 h. At the four subsequent time points, one prior to, and three following fluoride recharge, the BAG 81 composite released significantly more fluoride ions (p<0.05). Both composites were recharged by exposure to 5,000 ppm fluoride, although the BAG 81 composite was recharged more than the BAG 61 composite. The BAG 61 composite released substantially more calcium ions prior to fluoride recharge during each of the 2 and 22 h time periods. Thereafter, the release of calcium at the four subsequent time points was not significantly different (p>0.05) for the two composites. Significance These results show that, when added to a composite formulation, fluoride-containing bioactive glass made by the sol-gel route can function as a single source for both calcium and fluoride ions, and that the composite can be readily recharged with fluoride.

“…According to the manufacturer's instructions, Molloplast B should be used with an adhesive resin (Primo). This resin consists of γ‐methacryloxy‐propyltrimethoxysilane, which is a trialkoxysilane and one of the most studied silane compounds, especially for composite resin . However, Permaflex can be directly applied on the denture base resin.…”
