The objective was to investigate the influence of the material and dimensions of the orthodontic archwire on the pain and anxiety in adult patients in orthodontic treatment with brackets.
A randomized prospective triple-blind clinical pilot study was conducted at the Dental Clinic of the University of Salamanca. The study sample comprised 30 adult patients who started orthodontic treatment with brackets. This sample was divided into two groups: the NiTi group (n=15) and Cu-NiTi group (n=15). Pain was analyzed with a visual analogue scale (VAS) and anxiety with the State-Trait Anxiety Inventory (STAI). Anxiety was assessed at the start of treatment (T0) and after one month (T1). Pain was analyzed at the start of treatment (T0), at different time points at the start (T01), and after 4 (T02), 24 (T03), and 48 hours (T04); these measurements were also recorded one month after starting orthodontic treatment (T11, T12, T13, and T14).
The mean age of patients was 31.3 (± 6.05) years old. The highest level of pain, at the beginning of treatment, was observed after 48 hours (5.57 ± 1.72) and at one month after starting treatment at 24 hours (5.13 ± 1.89), with no significant differences between the two groups. When analyzing anxiety, no differences were observed between groups; the anxiety levels were higher one month after starting treatment compared to the start. Regarding the correlation between pain and anxiety, the NiTi group showed a greater direct relationship (<0.05) between these two variables at the start of treatment in the anxiety trait in relation to pain at T02 and T03 and after a month in T12, T13, and T14.
In the sample studied, there was no significant influence of the size or material of the orthodontic archwire on pain and anxiety levels. Orthodontics, Brackets, Archwire, Pain, Anxiety, NiTi, Cu-NiTi.
本研究旨在探讨正畸弓丝的材料和尺寸对成年患者使用托槽进行正畸治疗时疼痛和焦虑的影响。
在萨拉曼卡大学牙科诊所进行了一项随机前瞻性三盲临床试点研究。研究样本包括30名开始使用托槽进行正畸治疗的成年患者。该样本分为两组：镍钛组（n = 15）和铜镍钛组（n = 15）。采用视觉模拟量表（VAS）分析疼痛情况，使用状态-特质焦虑量表（STAI）评估焦虑状况。在治疗开始时（T0）和一个月后（T1）评估焦虑情况。在治疗开始时（T0）、开始时不同时间点（T01）、4小时（T02）、24小时（T03）和48小时（T04）分析疼痛情况；在正畸治疗开始一个月后（T11、T12、T13和T14）也记录这些测量值。
患者的平均年龄为31.3（±6.05）岁。治疗开始时，疼痛水平最高出现在48小时后（5.57±1.72）和开始治疗一个月后的24小时（5.13±1.89），两组之间无显著差异。分析焦虑情况时，两组之间未观察到差异；与治疗开始时相比，治疗一个月后的焦虑水平更高。关于疼痛与焦虑的相关性，镍钛组在治疗开始时，焦虑特质与T02和T03时的疼痛以及一个月后的T12、T13和T14时的疼痛之间，这两个变量之间显示出更大的直接关系（<0.05）。
