This work aimed to evaluate the salivary concentration of chemical elements in patients undergoing orthodontic treatment with fixed orthodontic appliances and removable aligners. Twelve Angle Class I and II orthodontic patients undergoing treatment with conventional fixed appliances and 15 patients treated with removable aligners provided unstimulated whole saliva samples before treatment (pre) and after 3 months of treatment (post). The concentration and secretion rate of chemical elements in saliva were determined by total reflection X-ray fluorescence. Differences from pre to post and between groups were determined with the paired T test or Wilcoxon test, and two-way ANOVA, considering P < 0.05. The concentrations of S, Cl, and K decreased, while Zn increased significantly (P < 0.05) between pre and post treatment with the fixed appliance treatment. The salivary secretion rate of S was decreased from pre to post in the fixed appliance group. No differences in the concentration and secretion rate of chemical elements were detected from pre to post in the Invisalign group. Fe secretion rate presented an interaction between time and treatment, with lower secretion at post (P = 0.02) in the Invisalign group. Increased Br secretion rate and decreased Rb, Fe, P, and K in Invisalign patients suggested a better salivary electrolyte profile regarding periodontal bone remodeling. No significant alterations in ions associated with metal corrosion and inflammatory reactions were detected in orthodontic patients under dental plaque control.

常规或 Invisalign 正畸治疗对矿物质和微量元素唾液水平的影响:全反射 X 射线荧光纵向研究。

这项工作旨在评估使用固定正畸矫治器和可移动矫治器进行正畸治疗的患者唾液中化学元素的浓度。12 名接受常规固定矫治器治疗的 Angle I 级和 II 级正畸患者和 15 名接受可移动矫正器治疗的患者在治疗前(前)和治疗后 3 个月(后)提供了未受刺激的全唾液样本。通过全反射X射线荧光法测定唾液中化学元素的浓度和分泌率。考虑到 P < 0.05,使用配对 T 检验或 Wilcoxon 检验和双向方差分析确定了前后和组之间的差异。S、Cl和K的浓度降低,而Zn的浓度显着增加(P < 0. 05) 前后治疗之间用固定矫治器治疗。固定矫治器组S的唾液分泌率从治疗前到治疗后降低。Invisalign 隐适美组前后未检测到化学元素浓度和分泌率的差异。Fe 分泌率呈现时间和治疗之间的相互作用,Invisalign 组的治疗后分泌较低 (P = 0.02)。Invisalign 隐适美患者的 Br 分泌率增加,Rb、Fe、P 和 K 降低,表明在牙周骨重塑方面唾液电解质分布更好。在牙菌斑控制下的正畸患者中没有检测到与金属腐蚀和炎症反应相关的离子的显着变化。固定矫治器组S的唾液分泌率从治疗前到治疗后降低。Invisalign 隐适美组前后未检测到化学元素浓度和分泌率的差异。Fe 分泌率呈现时间和治疗之间的相互作用,Invisalign 组的治疗后分泌较低 (P = 0.02)。Invisalign 隐适美患者的 Br 分泌率增加,Rb、Fe、P 和 K 降低,表明在牙周骨重塑方面唾液电解质分布更好。在牙菌斑控制下的正畸患者中没有检测到与金属腐蚀和炎症反应相关的离子的显着变化。固定矫治器组S的唾液分泌率从治疗前到治疗后降低。Invisalign 隐适美组前后未检测到化学元素浓度和分泌率的差异。Fe 分泌率呈现时间和治疗之间的相互作用,Invisalign 组的治疗后分泌较低 (P = 0.02)。Invisalign 隐适美患者的 Br 分泌率增加,Rb、Fe、P 和 K 降低,表明在牙周骨重塑方面唾液电解质分布更好。在牙菌斑控制下的正畸患者中没有检测到与金属腐蚀和炎症反应相关的离子的显着变化。Fe 分泌率呈现时间和治疗之间的相互作用,Invisalign 组的治疗后分泌较低 (P = 0.02)。Invisalign 隐适美患者的 Br 分泌率增加,Rb、Fe、P 和 K 降低,表明在牙周骨重塑方面唾液电解质分布更好。在牙菌斑控制下的正畸患者中没有检测到与金属腐蚀和炎症反应相关的离子的显着变化。Fe 分泌率呈现时间和治疗之间的相互作用,Invisalign 组的治疗后分泌较低 (P = 0.02)。Invisalign 隐适美患者的 Br 分泌率增加,Rb、Fe、P 和 K 降低,表明在牙周骨重塑方面唾液电解质分布更好。在牙菌斑控制下的正畸患者中没有检测到与金属腐蚀和炎症反应相关的离子的显着变化。
