Conventional orthodontic treatment with stainless steel orthodontic wires may be detrimental to oral health, as it contributes to demineralized lesions and increases adhesion and bacterial biofilm formation, which contributes to cavity development. An alternative that has been investigated to reduce the side effects of orthodontic treatment is the use of coating materials with antimicrobial nanoparticles. This study aims to evaluate the antiadherent and antibacterial properties of TiO2-coated and TiO2:Ag-coated stainless steel orthodontic wires against S. mutans bacteria.
In the sol-gel method, TiO2:Ag thin films were deposited on stainless steel orthodontic wires. Coated archwires were analyzed for their antibacterial and antiadherent properties. The evaluation of Streptococcus mutans adhesion to the orthodontic wires' surface was conducted according to the type of coating used, biofilm formation assay, and measurement of the pH of the bacterial community.
In the microbiological test, the TiO2:Ag coatings revealed a statistically significant difference in terms of microbial adhesion and biofilm formation by Streptococcus mutans. The TiO2:Ag coating on stainless steel wire increased pH levels in the saliva environment.
It can be concluded that antimicrobial orthodontic wires coated with silver TiO2 nanoparticles using the sol-gel thin film are a promising choice for improving orthodontic treatment.
使用不锈钢正畸丝进行传统正畸治疗可能对口腔健康有害，因为它会导致脱矿病变，并增加黏附力和细菌生物膜形成，进而促进龋齿发展。为减少正畸治疗副作用而进行研究的一种替代方法是使用含有抗菌纳米颗粒的涂层材料。本研究旨在评估二氧化钛涂层和二氧化钛:银涂层的不锈钢正畸丝对变形链球菌的抗黏附和抗菌性能。
采用溶胶-凝胶法在不锈钢正畸丝上沉积二氧化钛:银薄膜。对涂层弓丝的抗菌和抗黏附性能进行分析。根据所用涂层类型、生物膜形成试验以及细菌群落pH值测量，对变形链球菌在正畸丝表面的黏附情况进行评估。
在微生物测试中，二氧化钛:银涂层在变形链球菌的微生物黏附和生物膜形成方面显示出统计学上的显著差异。不锈钢丝上的二氧化钛:银涂层提高了唾液环境中的pH值。
可以得出结论，使用溶胶-凝胶薄膜法涂覆银二氧化钛纳米颗粒的抗菌正畸丝是改善正畸治疗的一个有前景的选择。
