Abstract：
BACKGROUND: In recent years, the demand for orthodontic treatment with aligners has increased, led by patient need, as aligners typically provide them with improved aesthetics and less physical discomfort. In deciding with the patient on an appropriate orthodontic system, it is important to take into account the potential discomfort and the perceptions that patients have in relation to their treatment. The objective of this study was to analyze the influence of brackets or aligners on oral health-related quality of life (OHRQoL) and anxiety levels in a sample of adult patients during the first month of treatment.
METHODS: The pilot study was carried out at the Dental Clinic of the University of Salamanca between November 2023 and February 2024. Eighty adult patients who initiated orthodontic treatment were selected and divided into two groups: the brackets group (Victory®; 3 M Unitek, California, USA) (n = 40) and the aligners group (Invisalign®; Align Technology, California, USA) (n = 40). OHRQoL was analyzed using the Oral Health Impact Profile-14 (OHIP-14) questionnaire, and anxiety was analyzed using the State-Trait Anxiety Inventory (STAI). The follow-up time was one month, with scores recorded at the beginning (T0) and one month after starting treatment (T1).
RESULTS: The mean patient age was 33.70 (± 5.45) years old. The total sample (n = 80) consisted of 66.2% men and 33.8% women. In the brackets group, one month after starting treatment, the dimension with the highest impact was that of physical pain (5.62 ± 1.51). In the aligners group, where the dimension of psychological disability had the highest score (4.22 ± 1.02). In the brackets group the total OHIP score was higher at one month (T1) (33.98 ± 6.81) than at the start of treatment (T0) (21.80 ± 3.34); this greater impact on OHRQoL one month after starting treatment was not observed in the aligners group (T1 = 27.33 ± 6.83; T0 = 27.33 ± 6.22). The orthodontic system used did not influence participants\' anxiety (p > 0.05). Age and sex were not influential factors in either OHRQoL or anxiety.
CONCLUSIONS: The bracket system significantly influenced patients\' OHRQoL. In the sample studied, no influence of the orthodontic system (brackets versus aligners) on anxiety was observed.

摘要：
背景：近年来，使用矫正器进行正畸治疗的需求增加了，由病人的需要，因为对准器通常为它们提供改进的美学和更少的身体不适。在与患者一起决定适当的正畸系统时，重要的是要考虑到潜在的不适和患者对治疗的看法。这项研究的目的是分析支架或矫正器对治疗第一个月的成年患者样本中口腔健康相关生活质量（OHRQoL）和焦虑水平的影响。
方法：试点研究于2023年11月至2024年2月在萨拉曼卡大学牙科诊所进行。选择了80名开始正畸治疗的成年患者，并将其分为两组：托槽组（Victory®；3MUnitek，加州,美国)(n=40)和对准器组(Invisalign®；对准技术，加州,美国)(n=40)。OHRQoL使用口腔健康影响概况-14(OHIP-14)问卷进行分析，使用状态特质焦虑量表(STAI)分析焦虑。随访时间为一个月,在开始（T0）和开始治疗后一个月（T1）记录评分。
结果：患者平均年龄为33.70(±5.45)岁。总样本（n=80）包括66.2％的男性和33.8％的女性。在括号组中，开始治疗一个月后，影响最大的维度是身体疼痛(5.62±1.51)。在校准器组中，其中心理残疾维度得分最高(4.22±1.02)。在支架组中，OHIP总评分在1个月（T1）（33.98±6.81）高于治疗开始时（T0）（21.80±3.34）；在开始治疗后一个月，未观察到对OHRQoL的更大影响（T1=27.33±6.83；T0=27.33±6.22）。使用的正畸系统不影响参与者的焦虑（p>0.05）。年龄和性别不是OHRQoL和焦虑的影响因素。
结论：支架系统显著影响患者OHRQoL。在研究的样本中，未观察到正畸系统（托槽与矫正器）对焦虑的影响。
