Fixed appliance orthodontic treatment may affect local saliva secretion; however, there is limited information available about this respect in the literature. Understanding how fixed appliance orthodontic treatment affects local saliva secretion could provide insight on possible contributions of salivary changes towards decalcification. In this study, we found that during the first month of fixed orthodontic treatment, the whole saliva flow rate, upper labial saliva flow rate and concentrations of whole saliva sodium and chlorine increased significantly, while the concentrations of calcium, phosphorous and potassium in whole saliva decreased. However, all these were in normal levels after 3 months. This study demonstrated that saliva flow rate was increased and saliva electrolytes were changed at early stage when placing fixed orthodontic appliances, which was considered due to increased mechanosensation.
固定矫正器正畸治疗可能会影响局部唾液分泌；然而，文献中对此方面的信息有限。了解固定矫正器正畸治疗如何影响局部唾液分泌，可以深入了解唾液变化对脱矿的可能影响。在这项研究中，我们发现，在固定正畸治疗的第一个月中，全唾液流速、上唇唾液流速以及全唾液中钠和氯的浓度显著增加，而全唾液中钙、磷和钾的浓度则降低。然而，所有这些在 3 个月后均恢复正常水平。本研究表明，在放置固定矫正器的早期，唾液流速增加，唾液电解质发生变化，这被认为是机械感觉增加的结果。
