METHODS: A total of 23 male and female patients (median age 25 y) treated with clear aligners were included. The OHRQoL questionnaire was used at certain time points during treatment (T1: placement of the first aligner; T2: after one day of use; T3: after seven days; T4: after one month; and T5: after one month in the retention phase). The State-Trait Anxiety Inventory (STAI) was also self-administered to assess state and trait anxiety (Y1 and Y2 subscales, respectively) at the T1, T4 and T5 time points. A population average generalized estimating equations logistic regression model was fit to assess the effect of time on the responses, and the Wald test was used to examine the overall effect of time.
RESULTS: Overall time was a significant predictor for most of the questions. However, time was marginally significant for the OHRQoL questions evaluating oral symptoms such as bad taste/smell, sores, and food accumulation. Tooth discolouration did not differ between time points. The general activity disturbance was significantly lower in the retention phase. Higher depression and anxiety scores were reported at the initial appointment and decreased thereafter.
CONCLUSIONS: CAT has a negative impact on quality of life and psychological status during the initial days of treatment. These impairments ameliorate at later treatment stages.
方法:共有23名男性和女性患者(中位年龄25岁)接受了清晰的对齐治疗。在治疗期间的某些时间点使用OHRQoL问卷(T1:放置第一矫正器;T2:使用一天后;T3:七天后;T4:一个月后;和T5:保留阶段一个月后)。状态-特质焦虑量表(STAI)也自行评估状态和特质焦虑(Y1和Y2分量表,分别)在T1、T4和T5时间点。拟合了总体平均广义估计方程逻辑回归模型,以评估时间对响应的影响,Wald检验用于检验时间的总体效应。
结果:总时间是大多数问题的重要预测因子。然而,OHRQoL问题评估口腔症状,如不良味道/气味,疮,和食物积累。牙齿变色在时间点之间没有差异。在保留阶段,一般活动干扰显着降低。在初次预约时报告了较高的抑郁和焦虑评分,此后下降。
结论:CAT对治疗初期的生活质量和心理状态有负面影响。这些损伤在后期治疗阶段得到改善。
