“…Stomatitis is a major complication in orthodontic treatment, which can lead to patient discomfort and increased medical costs [ 29 – 31 ]. The prolonged use of removable retainers also creates a suitable environment for C. albicans colonization and proliferation [ 32 ]. Therefore, this study aimed to develop a more effective antimicrobial-loaded material for removable orthodontic appliances to prevent and treat C. albicans infections while providing suitable physicochemical properties for clinical use.…”

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). 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.

“…7 Although Dental Cleaning Agents (DCA) are effective in removing mild tartar or slight discoloration, mechanical cleansing method remains essential and recommended due to the tenacious long-term adhesion of bio lm. [8][9][10] In this study, Melosira nummuloides, lava seawater diatoms primarily found during the low-temperature winter periods in the Northern Hemisphere's temperate regions, were identi ed in certain areas of Jeju Island. These diatoms effectively block heavy metals and harmful substances, leading to reduced chances of contamination.…”

High-temperature baking is a typical method to remove organic matter from diatoms, but it’s not suitable for bio-silica because of the high crystallinity. This study provides a method using the VAUS™ to remove organic matter from diatoms more quickly and biocompatibly. Organic matter was removed by using VAUS™, while NaOCl was utilized to remove the organic matter from the silicate frustule. The optimal frequency for organic matter removal was investigated to domestically produced M. nummuloides. The removal efficiency of TOC/TN was calculated and analyzed. The C and Si elements were analyzed in EDS, while visual confirmation of organic matter removal was analyzed by using XRD. TOC RE% at a frequency of 35kHz exhibited the highest value, indicating a statistically significant difference. XRD analysis demonstrated that the organic matter was almost removed using NaOCl compared to the high-temperature baked M. nummuloides. In the EDS analysis, there were significant differences in the C and Si elements with respect to frequency. This is very similar to the values from the positive control group, high temperature baked M. nummuloides. This new procedure of applying periodic negative pressure to NaOCl pre-treatment is considered to be an effective method of chemically removing organic matter from diatoms.
