“…It is important to determine the exural strength of acrylic resins with antimicrobial additives because it affects the potential for fracture in removable orthodontic retainers. Previous studies reported that the addition of Sr to PBG improved its chemical durability; however, the effects on physical durability are unclear [22]. In this study, there was no signi cant difference in the exural strength of 3.75% Sr-PBG compared to that of the control group; however, 7.5% and 15% Sr-PBG showed signi cantly lower exural strength values.…”

Acrylic resins are widely used as the main components in removable orthodontic appliances. However, poor oral hygiene and maintenance of orthodontic appliances provide a suitable environment for the growth of pathogenic microorganisms. In this study, strontium-modified phosphate-based glass (Sr-PBG) was added to orthodontic acrylic resin at 0% (control), 3.75%, 7.5%, and 15% by weight to evaluate the surface and physicochemical properties of the novel material and its antifungal effect against Candida albicans. Surface microhardness and contact angle did not vary between the control and 3.75% Sr-PBG groups (p > 0.05), and the flexural strength was lower in the experimental groups than in the control group (p < 0.05), but no difference was found with Sr-PBG content (p > 0.05). All experimental groups showed an antifungal effect at 24 and 48 h compared to that in the control group (p < 0.05). This study demonstrated that 3.75% Sr-PBG exhibits antifungal effects against C. albicans along with suitable physicochemical properties, which may help to minimize the risk of adverse effects associated with harmful microbial living on removable orthodontic appliances and promote the use of various materials.

“…However, the application of pure PBG is limited by its low chemical durability. The addition of strontium (Sr) to PBGs has been reported to improve chemical durability [22]. Sr can also promote remineralization of dentin and enamel and has been shown to stimulate dentin production by human dental pulp stem cells [23].…”

Acrylic resins are widely used as the main components in removable orthodontic appliances. However, poor oral hygiene and maintenance of orthodontic appliances provide a suitable environment for the growth of pathogenic microorganisms. In this study, strontium-modified phosphate-based glass (Sr-PBG) was added to orthodontic acrylic resin at 0% (control), 3.75%, 7.5%, and 15% by weight to evaluate the surface and physicochemical properties of the novel material and its in vitro antifungal effect against Candida albicans (C. albicans). Surface microhardness and contact angle did not vary between the control and 3.75% Sr-PBG groups (p > 0.05), and the flexural strength was lower in the experimental groups than in the control group (p < 0.05), but no difference was found with Sr-PBG content (p > 0.05).

“…These hybrid glasses should display intriguing physical and chemical characteristics. Glassy silicophosphate materials, including the patented Hench bioglass and similar bioactive glasses, along with their corresponding glass–ceramic forms, are recognized biomaterials [1–6]. With the advancement of planar technology, which enables the production of layered structures in microelectronic devices and integrated circuits, binary silicophosphate glass films have found significant utility in the electronics industry [7–9].…”

Erbium‐incorporated silicophosphate glasses are very desirable in principal sectors such as photonics, optoelectronics, lasers, and illuminating diodes. The focus of the current investigation has been on determining how the erbium dopant affects the optical, physical, and structural characteristics of the silicophosphate‐based glasses. The pure silicophosphate glasses and doped with various contents of erbium were prepared by the sol–gel process in this work. The noncrystalline character of the glasses synthesized was confirmed by the XRD patterns that were obtained. The optical measurement showed that the addition of trivalent erbium ions resulted in an increase in the refractive index of the samples and a decrease in their energy band gap values. It demonstrated the presence of P–O–P linkage stretching vibration modes that were both symmetrical and asymmetrical, P–O in PO4 bending vibration modes, OH group elongating and flexure vibrations, and P–O–H water absorption in glasses. The theoretical values of the optical basicity (Ʌth) increased from 0.465 to 0.472, while the values of the interaction parameter (A) decreased from 0.218 to 0.214 . Silicophosphate glasses doped with trivalent erbium ions show promise as optoelectronic and optical filter system materials.
