To examine the prophylactic potential of 3 orthodontic bonding adhesives: Fuji Ortho SC, Illuminate, and Resilience.
Thirty-six Wistar Wag rats were randomly divided into 4 groups consisting of 9 rats each. One of the groups received no treatment and was used as a control. In the other groups, individual bands coated with one of the 3 adhesives were cemented to the lower incisors. Enamel samples were obtained after 6 and 12 weeks and analyzed using scanning electron microscopy in combination with energy dispersive spectrometry.
Six weeks after band cementation, no fluoride was found in the enamel of the lower incisors. After 12 weeks, there was no fluoride in the enamel of teeth coated with the Resilience composite. However, in the case of the Illuminate composite and the resin-modified glass ionomer Fuji Ortho SC cement, the depth of fluoride penetration reached 2 µm and 4.8 - 5.7 µm, respectively.
Fluoride ions from orthodontic adhesives can be incorporated into the surface layer of the enamel. Orthodontists may apply orthodontic adhesives, such as the Fuji Ortho SC, to reduce the occurrence of caries during orthodontic treatment with fixed appliances.
研究三种正畸粘结剂Fuji Ortho SC、Illuminate和Resilience的预防潜力。
将36只Wistar Wag大鼠随机分为4组，每组9只。其中一组不接受治疗，作为对照组。在其他组中，将涂有三种粘结剂之一的单个带环粘结到下切牙上。在6周和12周后获取牙釉质样本，并结合能量色散光谱法使用扫描电子显微镜进行分析。
带环粘结6周后，在下切牙的牙釉质中未发现氟化物。12周后，涂有Resilience复合材料的牙齿牙釉质中没有氟化物。然而，对于Illuminate复合材料和树脂改性玻璃离子Fuji Ortho SC粘结剂，氟化物渗透深度分别达到2μm和4.8 - 5.7μm。
正畸粘结剂中的氟离子可掺入牙釉质表层。正畸医生可使用Fuji Ortho SC等正畸粘结剂，以减少固定矫治器正畸治疗期间龋齿的发生。
