Plaque control is especially important during orthodontic treatment because areas of the teeth near brackets and wires are difficult to clean with a toothbrush, resulting in debris buildup of food or dental plaque, thus causing caries and periodontal disease. The objective of this study was to evaluate the antimicrobial properties of silver nanoparticles (AgNPs), titanium dioxide nanoparticles (TiONPs), and silver/titanium dioxide nanoparticles (Ag/TiONPs), synthesized on the surface of α-alumina ceramic brackets. The AgNPs and TiONPs were synthesized by a simple chemical method, and these were characterized by XRD, SEM, and XPS TEM; the antimicrobial activity was tested against and by diffusion test. The results of this study demonstrated that by this simple chemical method, silver and titanium dioxide nanoparticles can be synthesized on the surface of α-alumina esthetic brackets, and these NPs possess good antimicrobial activity and the possibility of reducing dental caries, periodontal disease, and white spot generated during orthodontic treatment.
在正畸治疗期间，菌斑控制尤为重要，因为靠近托槽和弓丝的牙齿区域很难用牙刷清洁，会导致食物残渣或牙菌斑堆积，进而引发龋齿和牙周疾病。本研究的目的是评估在α-氧化铝陶瓷托槽表面合成的银纳米颗粒（AgNPs）、二氧化钛纳米颗粒（TiONPs）以及银/二氧化钛纳米颗粒（Ag/TiONPs）的抗菌性能。AgNPs和TiONPs通过简单的化学方法合成，并用XRD、SEM和XPS TEM对其进行表征；通过扩散试验测试其对 和 的抗菌活性。本研究结果表明，通过这种简单的化学方法，可以在α-氧化铝美观托槽表面合成银和二氧化钛纳米颗粒，这些纳米颗粒具有良好的抗菌活性，并且有可能减少正畸治疗期间产生的龋齿、牙周疾病和白斑。
