BACKGROUND
So far, a few studies have tried to investigate the relationship between the placement of fixed orthodontic appliances and the change of nonmicrobial salivary properties, mostly with conflicting outcomes and short-term assessment (up to 6 months from bracket placement). The purpose of this study was to evaluate the salivary flow rate, pH and buffer capacity prior to the beginning of therapy and after 1 year from bracket placement using a simple and commercially available chairside saliva check kit.
METHODS
The study population consisted of 20 healthy patients (mean age, 16.5±4 years) scheduled for fixed orthodontic treatment. Salivary samples were taken just before bracket bonding (T0; baseline assessment) and after 1 year of treatment (T1; half-treatment assessment) using the GC Saliva-Check Kit (GC Corp., Leuven, Belgium).
RESULTS
No statistically significant difference was detected between T0 and T1 for the salivary parameters examined in the present study.
CONCLUSIONS
Under the conditions of this study, the placement of fixed orthodontic appliances did not change the salivary pH, buffer capacity and flow rate after 1 year of treatment if compared with the baseline assessment.
背景
到目前为止，已有一些研究试图探究固定正畸矫治器的放置与非微生物唾液特性变化之间的关系，这些研究大多结果相互矛盾，且评估期较短（从托槽放置起长达6个月）。本研究的目的是使用一种简单且市售的椅旁唾液检测试剂盒，评估治疗开始前以及托槽放置1年后的唾液流速、pH值和缓冲能力。
方法
研究对象为20名计划接受固定正畸治疗的健康患者（平均年龄16.5±4岁）。使用GC唾液检测试剂盒（比利时鲁汶市GC公司）在托槽粘结前（T0；基线评估）和治疗1年后（T1；治疗中期评估）采集唾液样本。
结果
本研究中所检测的唾液参数在T0和T1之间未检测到统计学上的显著差异。
结论
在本研究条件下，与基线评估相比，固定正畸矫治器放置1年后并未改变唾液的pH值、缓冲能力和流速。
